You Are:

UST is seeking an innovative and hands-on Sr. AI/ML Engineer to join our AI transformation team. In this pivotal role, you will move beyond traditional modeling to design and deploy scalable AI Agents and GenAI frameworks.

The opportunity:

• AI Agent & GenAI Development

• Build Autonomous Agents: Design and deploy AI Agents using LangGraph, Google Agent Space, and the Agent Development Kit (ADK) to automate workflows, code generation, and data analysis tasks.

• GenAI Solutions: Develop advanced RAG (Retrieval-Augmented Generation) pipelines and LLM applications using LangChain and LlamaIndex, ensuring context awareness and high accuracy.

• Machine Learning & Engineering

• End-to-End Pipelines: Build and manage scalable ML pipelines from data ingestion to deployment, ensuring robust data wrangling and feature engineering.

• API Development: Expose AI models and agents as consumable services using FastAPI, ensuring low latency and high availability.

• Strategy & Leadership

• Technical Leadership: Drive the technical roadmap for AI initiatives, aligning development teams toward strategic objectives.

• Stakeholder Collaboration: Translate complex product and business requirements into ML-driven solutions, collaborating closely with SMEs, UX teams, and Product Managers.

This position description identifies the responsibilities and tasks typically associated with the performance of the position. Other relevant essential functions may be required.

What you need:

• Required Qualifications

• Education: Bachelor s or Master s degree in Computer Science, Data Science, Statistics, or a related field.

• Experience: 5-7 years of professional experience in Data Science, Machine Learning, or AI Engineering.

• Programming: Expert-level proficiency in Python and SQL with strong software engineering principles (clean code, version control).

• Core ML Stack: Expert proficiency in Python data stack (Scikit-learn, Pandas, NumPy, Statsmodels).

• Deep Learning: Experience with PyTorch or TensorFlow for complex non-linear problems.

• GenAI Stack: Hands-on experience with LLMs (Prompt Engineering, Fine-tuning) and orchestration frameworks like ADK, LangChain, and LangGraph.

• Cloud & DevOps: Strong understanding of Google Cloud Platform (GCP), specifically Google Vertex AI. Familiarity with Docker, Kubernetes, and CI/CD pipelines.

• API Integration: Experience building and deploying applications using FastAPI.

• Preferred Qualifications:

• Background in automating SDLC processes or building developer productivity tools.

• Knowledge of Vector Databases (e.g., Pinecone, Weaviate, Milvus).

• Adaptability & Mindset

• Learning Agility: A proven ability to rapidly upskill. You must be able to move from training a Logistic Regression model one day to fine-tuning a Llama-3 model the next.

• Problem-Solving Versatility: You understand when to use a simple rule-based system, when to use a Regressor, and when to use an LLM Agent. You do not force GenAI into every problem.

• Automation First: A mindset focused on automating your own workflows and the SDLC processes around you.
