About the role

Key responsibilities & impact

Build, refine, and use ML Engineering platforms and components; develop and implement scalable backend systems, APIs, and microservices using FastAPI.
Implement MLOps including model KPI measurement, tracking, model drift detection, and model feedback loops.
Deploy and operationalize ML and Deep Learning models, with a strong focus on LLMs and Generative AI.
Integrate Azure OpenAI (GPT-4, GPT-4 Vision) and other LLM providers with proper retry logic and error handling.
Maintain up-to-date knowledge of state-of-the-art technologies such as LLMs, GenAI, and transformer architectures.
Scale machine learning algorithms to work on massive data sets under strict SLAs.
Build and orchestrate model pipelines including feature engineering, inferencing, and continuous model training.
Write backend application code in Python and SQL using strong object-oriented principles and asynchronous programming (asyncio, async/await).
Implement dependency injection patterns and layered architecture (Service, Foundation, Orchestration, DAL).
Build LLM observability (e.g., Langfuse) to track prompts, tokens, costs, and latency.
Develop prompt management systems with versioning and fallback mechanisms.
Implement Celery (or similar) workflows for asynchronous task processing and complex pipelines.
Build multi-tenant architectures with client data isolation.
Implement cost optimization strategies for LLM usage (prompt caching, batch processing, token optimization).
Integrate third-party APIs and services (e.g., document/OCR services, cloud storage, enterprise systems).
Collaborate with client-facing teams to understand business context and contribute to technical requirement gathering.
Write production-ready code that is testable, maintainable, and accounts for edge cases and errors.
Ensure high quality of deliverables by following architecture/design guidelines, coding best practices, and periodic design/code reviews.
Write unit tests and higher-level tests to handle expected edge cases and errors gracefully.
Troubleshoot backend application code using structured logging and distributed tracing.
Use bug tracking, code review, version control, and other tools to organize and deliver work.
Participate in scrum calls and agile ceremonies, communicating progress, issues, and dependencies.
Document application changes and updates, including API documentation via OpenAPI/Swagger.
Research and evaluate emerging architecture patterns and technologies through rapid learning, proofs-of-concept, and prototypes.

Requirements

What you’ll need

Bachelor’s or Master’s degree in Computer Science or a related field.
Strong Python coding skills - 7+ years.
2+ years of hands-on experience with machine learning and production LLM systems.
Experience building backend APIs with FastAPI, async patterns, rate limiting, and SQLAlchemy - 3+ years.
Experience designing maintainable and extensible systems using dependency injection, interfaces, and abstract base classes.
Experience with vector databases such as Pinecone, Weaviate, or Chroma, as well as hybrid search.
Strong understanding of RAG architectures, including retrieval, reranking, context assembly, and response generation.
Hands-on experience with LangChain and LangGraph for building and orchestrating LLM workflows.
Advanced Python skills, including async/await, type hints, Pydantic, and SOLID principles.
MLOps experience with MLflow, model versioning, and A/B testing; experience with Langfuse is a plus.
Experience in NLP and computer vision, including document understanding, OCR, and GPT-4 Vision.
Experience building feature pipelines, real-time and batch inference systems, and model serving.
Hands-on experience with Hugging Face is required; experience with LlamaIndex is a plus.
Familiarity with database technologies such as SQL.
Good problem-solving skills and the ability to work in a fast-paced, team-oriented environment.
