Senior Backend Developer, AI

Summary

Build and own scalable Java/Spring Boot and Python backend services, integrate AI tools (LLMs, RAG, vector search) into workflows, and validate AI-generated code before production.


  • Build and own backend services using Java, Spring Boot, and Python-designed for scale, reliability, and real-time use.

  • Use AI tools (Amazon Q, Cursor, Copilot, Claude, GPT) to accelerate development, refactoring, and problem-solving.

  • Turn product ideas into production-ready systems quickly, without compromising quality.

  • Integrate AI capabilities (LLMs, RAG, vector search) into backend workflows where they add real value.

  • Act as the final filter for AI-generated code-identify flaws, inefficiencies, and incorrect assumptions before they ship.

  • Design clean APIs, handle distributed system challenges, and ensure performance at scale.

  • Write and validate tests to keep fast-moving systems stable.

  • Debug production issues and take full ownership of reliability and performance.

Requirements



  • Strong experience with Java (Spring Boot) and Python backend systems.

  • Experience building high-scale, low-latency distributed systems.

  • Solid understanding of APIs, databases, caching, and event-driven systems (e.g., Kafka).

  • Experience with cloud environments (AWS) and containerized deployments.

  • Familiarity with LLM APIs, token usage, latency, and response handling.

  • You are already using AI tools (Amazon Q, Cursor, Copilot, Claude, GPT) as part of your daily workflow.

  • You know how to manage context, structure prompts, and get reliable outputs from AI systems.

  • You don't trust AI blindly, you verify, refine, and take responsibility for every line shipped.
