Job Description

Job Title: Senior Full-Stack Engineer (Contract)

Company Overview:
NexaFlow is developing a next-generation automated code review tool powered by large language models (LLMs). We are seeking a Senior Full-Stack Engineer to build a proof-of-concept prototype from end to end.

Key Responsibilities:
- Design and implement an LLM-integrated code review system capable of analyzing pull requests, detecting bugs and security vulnerabilities, and providing contextual feedback within CI/CD pipelines.
- Own the entire proof-of-concept (PoC) process, including system architecture, LLM integration, static analysis pipeline, pull request webhook integration, review dashboard, and Docker-based deployment.
- Integrate LLM APIs such as OpenAI GPT-4 or Anthropic Claude into production systems.
- Develop and maintain CI/CD pipelines using tools such as GitHub Actions and GitLab CI.
- Incorporate static analysis tools such as Semgrep or CodeQL into the review workflow.
- Work independently from initial architecture through to deployment.

Requirements:
- 5+ years of full-stack development experience with Python or Node.js and React or Vue.
- Hands-on experience integrating LLM APIs (e.g., OpenAI GPT-4, Anthropic Claude) into production systems.
- Strong background in CI/CD pipeline development, including experience with GitHub Actions, GitLab CI, and code review tooling.
- Experience with static analysis tools such as Semgrep or CodeQL.
- Ability to work independently and take ownership of the entire PoC lifecycle.
- Familiarity with Retrieval-Augmented Generation (RAG) architectures and vector databases is a plus.

Contract Details:
- Contract role with potential for extension.
- Location: San Francisco; remote-friendly.

If you are passionate about building innovative developer tools and have a strong background in full-stack engineering and LLM integration, we encourage you to apply.
