Full Job Posting

Job requirements

  • 3–8 years of professional software development experience, with at least 1–2 years focused on Generative AI or LLM application development.
  • Hands-on production experience building LLM-powered applications using LangChain and/or LangGraph.
  • Practical experience with Hugging Face — using pre-trained models, the Transformers library, or the Inference API.
  • Working knowledge of RAG architectures, vector databases (e.g. Pinecone, Weaviate, pgvector, or MongoDB Atlas Vector Search), and embedding techniques.
  • Strong Python skills — writing clean, well-tested, and maintainable code, ideally with experience in FastAPI or similar API frameworks.
  • Working proficiency in the MEAN stack: MongoDB, Express.js, Angular (17+), and Node.js.
  • Experience designing and consuming REST APIs; familiarity with GraphQL is expected for this role.
  • Comfortable using Git and working within modern CI/CD workflows.
  • Clear communicator who works effectively with both technical and non-technical stakeholders.
  • Experience deploying AI-powered applications on any one of the cloud providers: AWS, Azure, or GCP.
  • Exposure to LLM evaluation frameworks, observability tools (e.g. LangSmith, Langfuse), or fine-tuning workflows.
  • Prior experience integrating third-party AI APIs (OpenAI, Anthropic, Bedrock, Cohere) in production.
  • Familiarity with MongoDB Atlas Vector Search or other native vector capabilities in operational databases.
  • Experience in an agile team environment with iterative product delivery.

Job responsibilities

  • Design, develop, and maintain LLM-powered application features using Python and frameworks such as LangChain and LangGraph.
  • Build and maintain Retrieval-Augmented Generation (RAG) pipelines — including chunking, embedding, retrieval, and re-ranking strategies.
  • Integrate Hugging Face models and APIs for text generation, classification, embeddings, and semantic understanding tasks.
  • Develop and tune prompt engineering strategies, manage LLM context, and ensure reliable, production-grade outputs.
  • Build agentic workflows using LangGraph — orchestrating tool use, multi-step reasoning, and stateful agent behaviour.
  • Expose AI capabilities through clean Python APIs (e.g. FastAPI) that the MEAN application can consume.
  • Apply responsible AI principles, ensuring solutions are fair, explainable, and aligned with organisational and regulatory standards.
  • Evaluate and recommend emerging Generative AI tools, models, and frameworks that add tangible value to the product.
  • Contribute to the MEAN application (MongoDB, Express.js, Angular, Node.js), with a focus on integrating AI services into the product experience.
  • You will also collaborate on the user-facing application — touching Node.js APIs, MongoDB, and Angular where needed to integrate AI capabilities — but the depth of ownership sits with the Python AI services.
  • Participate in code reviews to uphold quality and share knowledge across the team.
  • Troubleshoot and debug issues across the stack — from LLM response quality and retrieval accuracy to API performance and UI integration.
  • Contribute clear technical documentation for AI services, APIs, and integration points.
  • Work within agile/scrum delivery practices, collaborating closely with product managers and fellow engineers.

Job benefits

  • A collaborative engineering team working on meaningful, real-world Generative AI problems.
  • Opportunities to grow into senior and leadership roles as the team scales.
  • Access to cutting-edge Gen AI tools, models, and a culture of continuous learning.
  • Flexible working arrangements and a commitment to work-life balance.
