Full-Stack AI Developer Needed

TrueMarch (truemarch.com) is an applied AI and decentralized infrastructure company. We are looking for experienced software and AI developers for ongoing contract work, with the possibility of a long-term engagement. What you will work on: - Full-stack web applications and APIs using TypeScript, Node.js, React and Next.js - AI features built on large language models: prompt design, retrieval (RAG), tool use and agent workflows - Evaluation and testing of AI features before release - Data pipelines and backend services that need to run reliably in production Trial Phase Deliverables (2 weeks): 1. A Next.js + Node.js (TypeScript) app with a simple question-and-answer feature over a set of documents we provide, using an LLM API with retrieval (RAG). 2. A REST API endpoint for asking questions, plus a basic web page to use it. 3. Automated tests for the API, and a small evaluation set (about 10 questions with expected answers) showing how accurate the answers are. 4. Code in a private GitHub repository with a README explaining how to set it up, run it and deploy it. 5. A short written summary of design choices, limitations and what you would improve next. We will review the work on code quality, correctness, test coverage and clear communication during the two weeks.
