About the Role
We are looking for a Senior Machine Learning Engineer with 5 -6 years of industry experience to lead the design, development, and deployment of AI-powered systems. This role combines hands-on ML engineering, backend development, LLM integration, and production-grade infrastructure work.
You will work closely with product and engineering teams to build reliable, scalable, and high-impact machine learning features.
Key Responsibilities
Machine Learning & LLMs :
- Integrate LLMs (OpenAI, Anthropic, etc.) into pipelines - prompting, workflows, RAG, evaluation, and iteration.
- Design robust prompt engineering strategies and maintain prompt libraries across environments.
- Improve model performance via finetuning, quantization, pruning, or distillation when needed.
- Build, train, finetune, and optimize ML and LLM-based models for production use cases.
Backend Engineering :
- Develop scalable backend systems using Python (FastAPI/Flask preferred).
- Architect and integrate REST APIs, rate limiting, and monitoring.
- Debug, profile, and optimize API performance in production.
Infrastructure & DevOps :
- Build and deploy containerized applications using Docker.
- Manage model and service deployments on Kubernetes (EKS, GKE, AKS or self-managed clusters).
- Work with CI/CD pipelines to ensure smooth releases and automated testing.
- Implement logging, monitoring, and alerting for ML and backend services.
Collaboration & Leadership :
- Work closely with cross-functional teams to convert business problems into ML solutions.
- Provide technical guidance to junior engineers and contribute to architectural decisions.
- Bring a strong bias for shipping, iteration, and maintaining high engineering standards.
Required Skills & Experience :
- 5 - 6 years of hands-on experience as an ML Engineer or similar role.
- Expert-level Python programming and clean code practices.
- Strong experience designing and integrating production APIs.
- Practical experience integrating LLM models and writing optimized prompts.
- Strong understanding of model finetuning, hyperparameter tuning, and inference optimization.
- Experience with Docker, containerized deployments, and Kubernetes orchestration.
- Good understanding of microservices architecture, distributed systems, and cloud infrastructure.
- Solid problem-solving and debugging skills across the ML lifecycle.
Nice-to-Have :
- Experience with vector databases (Pinecone, Weaviate, FAISS).
- Experience with event-driven architecture (Kafka, Pub/Sub, SQS/SNS).
- Exposure to data pipelines (Airflow, Prefect, Dagster).
