Job Description & How to Apply Below

Nexa Flow is building a next-generation code review tool powered by large language models. We are seeking a Senior Full-Stack Engineer to lead the development of a proof-of-concept prototype that integrates LLM-based analysis into existing CI/CD workflows.

Responsibilities:
  • Design and implement a full-stack application that integrates LLM APIs (OpenAI/Anthropic) for automated code review.
  • Build webhook-based integrations with Git Hub/Git Lab to automatically analyze pull requests.
  • Develop a hybrid analysis pipeline combining LLM reasoning with static analysis for bug detection, security vulnerability identification, and code quality enforcement.
  • Create a configurable rule engine allowing per-repository custom review policies.
  • Build a dashboard displaying review statistics, trends, and actionable insights.
  • Containerize the entire solution with Docker for easy self-hosted deployment.
  • Own the full lifecycle from architecture design through deployment and documentation.
Requirements:
  • 5+ years of professional full-stack development experience.
  • Strong experience integrating LLM APIs (OpenAI GPT-4, Anthropic Claude) into production systems.
  • Hands-on experience with CI/CD pipeline integration (Git Hub Actions, Git Lab CI).
  • Prior work building code review tools, linters, or static analysis systems.
  • Proficiency in Python (FastAPI) or Node.js for backend;
    React or Vue for frontend.
  • Experience with Docker containerization and self-hosted deployment.
  • Ability to work independently across the full stack from architecture to deployment.
  • Strong communication skills for async collaboration.
Nice to Have:
  • Experience with RAG (Retrieval-Augmented Generation) architectures.
  • Familiarity with CodeQL, Semgrep, or similar static analysis tools.
  • Previous startup or PoC-stage project experience.
  • Contributions to open-source developer tools.
Additional Information:
  • This is a contract/consulting engagement, not a full-time employee role.
  • We value flexibility and outcome-driven collaboration.
  • Remote-friendly with a preference for candidates in the San Francisco Bay Area.
