Contract</p></div>
<div><div><div><div><div>
Our client is a fast-growing healthcare company providing autism diagnostics, therapy, and medical services to young children across the United States. As part of that growth, the Data, AI, and Automation team is building the cloud infrastructure needed to move internal algorithmic tools from desktop execution to production-grade, browser-based services.</div><br>
<br>
<div>They're looking for a <b>Senior Backend Engineer</b> (6+ years of experience) to own the web application platform that productizes an in-house scheduling solver as a secure, internal cloud service. The solver&mdash;a Python-based optimization engine&mdash;currently runs as a desktop app with Excel workflows. Your job is to build the cloud platform around it: authentication, backend orchestration for long-running workloads, artifact and version management, integrations with BigQuery and Google Sheets, and production-grade operability. The web UI is intentionally simple and utilitarian&mdash;a small set of buttons, a run console, and basic pages for upload, run, status, download, and publish. The core of this role is backend architecture, not frontend polish.</div><br>
<br>
<div>You'll collaborate closely with a dedicated algorithm expert who owns the solver codebase&mdash;you won't need to develop or deeply understand the Python algorithm itself. The two codebases have clear domain ownership connected by well-defined input/output contracts. You'll report to the VP and have significant autonomy to make architectural decisions and drive the platform forward. Longer term, the platform you build is designed to be extensible: other teams at the company are building their own algorithms and automation, and your platform will serve as the template for containerizing and orchestrating additional workloads. This is the foundation of a broader internal platform, not a one-off project.</div><br>
<br>
<div>This is a <b>long-term contract opportunity</b> without an end date. The engagement is <b>fully remote</b>, and candidates can be <b>located anywhere in Latin America</b>. You'll need strong English communication skills (B2+ or higher) for this role.</div>
<br>
<b>Responsibilities</b><br>
<ul><li>Own the web application platform on GCP: authentication/authorization, APIs, storage, service architecture, and a simple utilitarian web UI.</li>
<li>Build reliable long-running job execution for the solver&mdash;queueing, concurrency limits, cancellation, retries&mdash;optimized for low wait time and iterative use.</li>
<li>Own end-to-end workflow I/O and integrations: maintain the existing Excel-in/Excel-out experience, enable safe and auditable publish to Google Sheets, and integrate with BigQuery for data enrichment and metrics/reporting.</li>
Define and maintain the platform<li> solver contract (I/O bundle format, versioning, error taxonomy, logging) in partnership with the algorithm owner.</li>
<li>Implement PHI-safe security and compliance controls in partnership with the Security Engineer: least-privilege IAM, encryption, secrets management, and audit logging.</li>
<li>Establish production operability in partnership with the DevOps Engineer: CI/CD, monitoring/alerting, and support/run-diagnostics tooling.</li>
</ul><b>Mandatory Requirements</b><br>
<ul><li>6+ years building production backend systems and platforms (internal tools and/or customer-facing).</li>
<li>Strong experience with client-server distributed architectures.</li>
<li>Comfortable designing and building asynchronous/event-driven systems (e.g., publish/subscribe, queues, streaming) for long-running workloads.</li>
<li>Proficiency building systems that implement stateful resources: relational and/or non-relational databases and object storage.</li>
<li>Strong familiarity with at least one major cloud provider (GCP, AWS, or Azure)&mdash;with the ability and willingness to work in GCP as the production environment.</li>
<li>Comfortable containerizing and packaging application code (Docker, container registries, orchestration).</li>
<li>Comfortable using Git and CI/CD tools (e.g., GitHub Actions/Workflows).</li>
<li>Ability to model and implement execution pipelines using state machines/workflows (durable job state, retries, idempotency, compensating actions).</li>
<li>Strong experience in at least one backend language (Go, Java, Python, or equivalent). The solver codebase is Python&mdash;you don't need to be a Python expert, but you must be comfortable reading, packaging, and containerizing Python code.</li>
<li>Experience designing secure systems (authn/authz, secrets handling, encryption, audit logging), including PHI/PII-safe logging.</li>
<li>Strong cross-team collaboration skills and ability to define ownership boundaries and contracts.</li>
</ul><b>Nice-to-Have</b><br>
<ul><li>Experience with Google Cloud Platform specifically (Cloud Run, Pub/Sub, BigQuery, IAM).</li>
<li>Experience with optimization/solver workloads (OR-Tools, MILP, etc.).</li>
<li>Experience with healthcare data compliance (HIPAA) and BAA-oriented vendor setups.</li>
<li>Experience with cloud-native container orchestration (e.g., Kubernetes, Cloud Run).</li>
<li>Experience with Excel ingestion/export pipelines.</li>
<li>Experience with JavaScript frameworks (e.g., React) for simple internal UIs.</li>
</ul><b>What We're Looking For Beyond the Tech Stack</b><br>
Beyond the technical requirements, this team is looking for a specific type of engineer:<br>
<ul><li><b>Startup mindset over big-tech process. </b>You own outcomes, not tickets. You think about whether the work you're doing is useful, not just whether it's assigned.</li>
<li><b>Genuine curiosity and love of learning. </b>You pick up new domains and tools quickly because you're naturally drawn to understanding how things work. You've built things on your own time just to learn.</li>
<li><b>Adaptability over certification stacking. </b>They care about foundational engineering ability and the capacity to grow, not a perfect resume match on every specific technology.</li>
<li><b>Comfort with ambiguity. </b>You're building infrastructure for a team that includes non-engineers who are developing algorithms. The terrain is new and evolving, and you're excited by that, not unsettled.</li>
</ul><b>What Success Looks Like</b><br>
<ul><li><b>3 months &mdash; V1 prototype in pilot: </b>V1 web app platform running real Base Schedule workflows end-to-end for a small pilot cohort (Google SSO, validate/solve job orchestration, Excel artifact management, per-run status/logs, and a basic publish flow).</li>
<li><b>6 months &mdash; V1 rollout complete: </b>V1 is the default execution path for schedulers (production rollout complete): reliable parallel runs with low queue time, versioned publish to Google Sheets with audit trail, solver quality metrics landing in BigQuery for analytics, and a repeatable release/rollback workflow with DevOps.</li>
<li><b>9 months &mdash; V2 in prototype: </b>V2 Week Ahead workflow running in prototype (cloud-executed Week Ahead + early cross-center allocation orchestration), with the operational scaffolding needed to evaluate rollout (monitoring, support playbook, and clear success criteria for V2).</li>
</ul><b>Of Note</b><br>
<ul><li>A company laptop will be provided.</li>
<li>HIPAA compliance training is required before the start date.</li>
<li>Completed background checks will be required before the start date if you are selected as a winning candidate.</li>
<li>As a winning candidate, you will be required to disclose your engagement with DevEngine as a primary client on your professional LinkedIn profile.</li>
</ul>

Rest assured that your application will be carefully reviewed and considered. We appreciate your understanding and interest in joining our team.</div></div></div></div></div></div><p></p>

Senior Backend Engineer (Java)

Luxoft

<div><div><h5 class="jobSectionHeader"><b>Project description
</b></h5><div>The paradigm of software is shifting from reactive to proactive. At Luxoft, we are at the forefront of this transformation, engineering the next generation of Agentic AI systems. We are seeking an exceptional Backend Engineer to architect the core infrastructure for software that doesn't just execute commands, but reasons, plans, and acts autonomously.<br>
<br>
As a key member of our elite AI Core team, you will move beyond traditional backend development to build the central nervous system for our AI agents. This role is for a true systems builder&mdash;someone passionate about creating robust, scalable, and intelligent platforms that empower autonomous AI to solve complex, real-world problems. You will be instrumental in crafting the bridge between raw data and digital cognition.<br>
<br>
What You'll Be Building: The Engine of Intelligence<br>
<br>
As our Backend Engineer for Agentic Systems, you will own the end-to-end lifecycle of the agent's core infrastructure&mdash;from its memory and logic to its deployment and operational resilience.<br>
<br>
<ul><li>The Agent's Communication Backbone: You will wield FastAPI and Pydantic to design and build high-throughput, asynchronous, and self-documenting APIs. These are more than just endpoints; they are the high-bandwidth channels through which our agents perceive data, communicate their intent, and interact with external tools and systems. Your Pydantic models will define the rigorous data contracts that ensure absolute integrity across our distributed environment.</li></ul><br>
<ul><li>The Agent's Cognitive Framework: You will architect and implement the core systems that enable agentic behavior. This involves developing sophisticated state machines, implementing advanced reasoning loops (e.g., ReAct, Chain-of-Thought), and orchestrating the workflows that allow agents to plan, delegate tasks, and leverage a diverse suite of tools.</li></ul><br>
<ul><li>The Agent's Memory and Knowledge Base: An agent's power lies in its ability to learn and recall. You will be the steward of our agents' memory systems, leveraging the reliability of PostgreSQL. You will design and manage complex database schemas for storing conversation histories, learned knowledge graphs, and operational logs. Your expertise in database management and optimization will be critical to ensuring our agents can access information instantaneously as their knowledge scales.</li></ul><br>
<ul><li>The Agent's Operational Habitat: Our AI agents must be deployed with unwavering reliability and scale on demand. You will master Docker to containerize our entire agentic ecosystem, creating reproducible, isolated, and portable environments that guarantee consistency from development to production.
</li></ul></div></div><div><h5 class="jobSectionHeader"><b>Responsibilities</b></h5>
<div><div><p>Architect &amp; Develop: Design, build, and maintain high-performance backend services in Python, using FastAPI for our core agentic platform.
</p></div><div><p>Model Reality: Implement complex data validation and serialization schemas with Pydantic to ensure data integrity across our distributed systems.
</p></div><div><p>Empower Agents: Develop the core logic for AI agents, including tool integration, state management, and multi-step reasoning frameworks.
</p></div><div><p>Manage Data Persistence: Design, optimize, and manage PostgreSQL databases. Write efficient SQL queries, manage migrations, and ensure the long-term health and scalability of our data stores.
</p></div><div><p>Containerize &amp; Deploy: Create and maintain clean, efficient Dockerfiles and Docker Compose configurations for all backend services, streamlining our deployment pipelines.
</p></div><div><p>Collaborate &amp; Innovate: Work in close partnership with AI Researchers, Prompt Engineers, and Frontend Developers to deliver cohesive, end-to-end intelligent solutions.
</p></div><div><p>Test &amp; Harden: Author comprehensive unit and integration tests to guarantee the reliability and robustness of the foundational systems powering our agents.
</p></div></div></div><div><h5 class="jobSectionHeader"><b>Skills</b></h5>
<p>Must have
</p><div><div><p>Technical Excellence:
</p></div><div><p>Proven Professional Experience: A minimum of 3 years in backend engineering, with a strong portfolio of building scalable, production-grade systems using robust Python skills. This includes deep, hands-on experience with database management.
</p></div><div><p>Deep expertise in FastAPI and a strong appreciation for its asynchronous capabilities.
</p></div><div><p>Mastery of Pydantic for creating strict, type-safe data models that enforce architectural clarity.
</p></div><div><p>Experince in any of common agentic frameworks such as langGraph, Pydantic-AI, Google ADK, Agno or any similar framework
</p></div><div><p>Strong command of PostgreSQL, including advanced schema design, query optimization, and indexing strategies.
</p></div><div><p>Production-level experience with Docker, with a proven ability to write clean, multi-stage Dockerfiles and manage containerized applications.
</p></div><div><p>The Agentic Mindset:
</p></div><div><p>A profound passion for AI and a demonstrable interest in agentic systems. You have likely experimented with frameworks like LangChain, LlamaIndex, or AutoGen, or you possess a strong desire to build such systems from fundamental principles.
</p></div><div><p>A systems-thinking approach. You can visualize how disparate components&mdash;LLMs, databases, APIs, and tools&mdash;integrate to form a single, intelligent entity.
</p></div><div><p>Personal Attributes:
</p></div><div><p>Insatiable Curiosity: You are constantly learning and exploring the bleeding edge of AI and software engineering.
</p></div><div><p>Ownership Mentality: You don't just write code; you take ownership of the systems you build and are accountable for their performance and reliability.
</p></div><div><p>Collaborative Spirit: You thrive in a team environment, sharing knowledge and elevating those around you.
</p></div></div><p>Nice to have
</p><div><div><p>Experience with vector databases (e.g., Pinecone, Chroma, Weaviate).
</p></div><div><p>Knowledge of cloud platforms (AWS, GCP, Azure) and infrastructure-as-code (Terraform)
</p></div><div><p>Familiarity with CI/CD pipelines (e.g., GitHub Actions, GitLab CI)
</p></div><div><p>Experience with message queues (e.g., RabbitMQ, Kafka) for asynchronous task processing.
