About the Role

You will join our team to architect and build serverless services, low-latency GraphQL & event APIs, and AI agent orchestration capabilities that connect to leading LLM providers.

Your Responsibilities

  • Create execution flows, tool/function calling, conversation state & memory models, and provider abstraction layers.
  • Implement NestJS serverless (Lambda + API Gateway) services, scalable GraphQL schemas/resolvers, and focused REST endpoints.
  • Use event-driven patterns (pub/sub, async triggers) for orchestration, streaming responses, and action agent pipelines.
  • Enforce TDD; expand Jest suites (unit, integration, contract) for Lambdas & GraphQL.
  • Profile hot paths (invocation latency, cold starts, resolver timing), optimize caching & streaming strategies.
  • Enable conversational UI consumption via lightweight components & GraphQL patterns—keep abstractions clean.
  • Follow ADRs, sequence diagrams, API specs, and operational runbooks.
  • Refine coding standards, automate quality gates (ESLint, SonarQube), and evolve build/test acceleration for a large codebase.

Requirements

  • 8+ years professional full stack development with clear depth in backend architecture & distributed systems.
  • NestJS (primary), Node.js, Express.js, GraphQL, REST API design, MongoDB operations.
  • Hands-on with OpenAI/Anthropic and/or AWS Bedrock.
  • Deployment of AWS Lambda, and event-driven patterns.
  • Working knowledge of TypeScript, Web Components, and integrating framework-agnostic UI components.
  • Designing modular services and scalable API surface areas for a large multi-team codebase.
  • Bachelor's degree in Computer Science / Engineering or equivalent experience.

Benefits

  • Build AI workflows.
  • Deliver at scale with measurable reliability goals.
  • Continuously learn in a fast-moving AI + serverless ecosystem.
  • Contribute to social responsibility and inclusive culture initiatives.
  • Join a company committed to equality, equity, and inclusive growth.
