Backend Software Engineer - Innovative Growth

Zettasoft-egypt

<div>
 
 
 About Zettasoft
 
 
 
 Zettasoft is a software development company with offices in New York and Cairo. We solve business problems with technology, partnering with clients to design and build modern, AI-enabled platforms that move their business forward. You can learn more at zettasoft.com.
 
 
 
 
 
 
 About the Role
 
 
 
 We are building the next generation Cybersecurity Management Platform &mdash; a product that unifies security posture and response workflows into a single pane of glass, with LLM-powered automation at its core. We are hiring a Senior Backend Engineer to help architect and build the services that power it.
 
 
 You will own backend systems end-to-end: from API design and data modeling, to LLM-orchestrated workflows, to production deployment on a modern container platform. You will write code, set the bar for engineering quality, and shape how AI coding agents are used inside our team. This is a high-ownership role for an engineer who genuinely enjoys shipping secure, well-tested software and wants to work on a product where security correctness is a feature, not an afterthought.
 
 
 
 
 
 
 What You'll Do
 
 
 
 &bull;&nbsp;&nbsp;&nbsp;Design, build, and operate backend services in
 
 Python
 
 using
 
 Django
 
 and
 
 FastAPI
 
 for our cybersecurity management platform.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Architect LLM-powered features using the Anthropic or OpenAI APIs &mdash; prompts, tool use, retrieval, evaluation, guardrails, and cost/latency controls.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Design clean, well-documented REST and async APIs and the data models behind them; make pragmatic trade-offs between speed, simplicity, and long-term maintainability.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Build and operate services as part of a modern microservices architecture, deployed as containers (Docker) and orchestrated with Kubernetes or equivalent.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Write secure code by default: apply OWASP Top 10 thinking to every endpoint, review peers' code for security flaws, and partner with security stakeholders on threat modeling.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Use Claude Code, Codex, or similar AI coding agents as part of your daily workflow &mdash; delegating to them where it accelerates quality, and knowing when not to.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Own your services in production: observability, SLOs, on-call, incident response, and continuous improvement.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Raise the engineering bar through code review, design review, mentorship of junior engineers, and thoughtful technical writing.
 
 
 
 
 
 
 
 
 
 What We're Looking For
 
 
 
 
 Must-haves
 
 
 
 &bull;&nbsp;&nbsp;&nbsp;5+ years of professional backend engineering experience building production services in
 
 Python
 
 .
 
 
 &bull;&nbsp;&nbsp;&nbsp;Strong hands-on experience with both
 
 Django
 
 and
 
 FastAPI
 
 &mdash; you understand when to reach for each and why.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Shipped features that integrate
 
 LLMs
 
 (Anthropic or OpenAI) into real products &mdash; not just demos. You have opinions on prompt design, tool/function calling, evaluations, and controlling cost and latency in production.
 
 
 &bull;&nbsp;&nbsp;&nbsp;You write
 
 secure code by default
 
 and are deeply familiar with the
 
 OWASP Top 10
 
 &mdash; injection, broken access control, SSRF, insecure deserialization, and the rest. You spot these in code review without being asked.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Experience designing and operating
 
 modern microservices architectures
 
 with container-based deployment (Docker + Kubernetes or equivalent).
 
 
 &bull;&nbsp;&nbsp;&nbsp;You actively
 
 use and embrace AI coding agents
 
 &mdash; Claude Code, Codex, or similar &mdash; and can speak to how they have changed the way you ship code.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Strong grounding in relational databases (PostgreSQL), async patterns, testing, and production observability.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Deep knowledge of
 
 REST API design
 
 &mdash; resource modeling, versioning, pagination, error semantics, idempotency &mdash; and a point of view on where REST stops being the right tool.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Hands-on experience authoring
 
 OpenAPI (Swagger) specifications
 
 &mdash; using them for contract-first design, client and server code generation, and keeping documentation honest as the API evolves.
 
 
 &bull;&nbsp;&nbsp;&nbsp;
 
 DevOps experience building and operating CI/CD pipelines
 
 &mdash; GitHub Actions, GitLab CI, or equivalent &mdash; with automated testing, security scanning, and progressive deployment to production.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Clear written and verbal communication in English; comfortable collaborating across time zones with our New York team.
 
 
 
 
 
 
 Nice-to-haves
 
 
 
 &bull;&nbsp;&nbsp;&nbsp;Prior experience in the cybersecurity domain: SIEM, SOAR, EDR/XDR, vulnerability management, cloud security, or compliance automation.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Experience with event-driven architectures (Kafka, NATS, SQS) and workflow orchestration (Temporal, Celery, Airflow).
 
 
 &bull;&nbsp;&nbsp;&nbsp;Experience with retrieval-augmented generation, vector databases, or agentic systems in production.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Familiarity with infrastructure as code (Terraform), cloud platforms (AWS/GCP/Azure), and secure SDLC practices.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Contributions to open-source Python or security tooling.
 
 
 
 
 
 
 
 
 
 What We Offer
 
 
 
 &bull;&nbsp;&nbsp;&nbsp;A senior seat on a small, high-ownership team building a greenfield platform &mdash; your architectural decisions will matter for years.
 
 
 &bull;&nbsp;&nbsp;&nbsp;A codebase where AI-assisted engineering is a first-class practice, not an afterthought.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Competitive compensation, meaningful scope, and a genuine voice in how the product and the engineering org are built.
 
 
 &bull;&nbsp;&nbsp;&nbsp;Fully remote work from anywhere in Egypt.
 
 
 &bull;&nbsp;&nbsp;&nbsp;A
 
 full-time role on a one-year renewable contract
 
 &mdash; with the clear expectation of long-term continuation for the right person, as the platform is a multi-year commitment.
 
 
 
 
 
 
 
 
 
 How to Apply
 
 
 
 Send your r&eacute;sum&eacute;/CV, a link to code you are proud of (GitHub, a production service you led, or a non-trivial side project), and a short note on one LLM-powered feature you have shipped &mdash; what was hard about it, and what you would do differently next time &mdash; to career@zettasoft.com.
 
 
 
 Zettasoft is an equal opportunity employer. We evaluate applicants on the strength of their work and their fit for the role, and we welcome candidates from all backgrounds.
