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.

- 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.

- 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 role with potential for extension.
