Fullstack Developer (Python/React)

About Us

micro1 is the end-to-end human data infrastructure behind AGI. Our AI recruiter model is used by frontier AI labs and Fortune 10s to source, vet, and deploy PhDs and professors from the world’s top universities at scale. These experts are placed directly into the training loops of the most advanced AI systems, powering the breakthroughs that move models forward. Our data platform converts their expertise into high-signal training datasets, and our talent management tooling measures, routes, and improves performance at scale.

What You’ll Do

You’ll help design, build, and ship production systems end-to-end. This is a hands-on role for someone who’s comfortable owning features from UI to infrastructure, moving fast, and making good tradeoffs under real constraints. You’ll work closely with a small, senior, remote team to turn rough ideas into reliable software.

Responsibilities

Build scalable and high-performance backend APIs using Python and FastAPI to support new feature development. Develop and enhance frontend interfaces using React, Next.js, and TypeScript to support evolving product workflows. Integrate LLMs and AI Agents into the platform (e.g., trainer feedback systems and AI-assisted workflows). Implement concurrency patterns and backend optimizations to improve system performance and handle increasing workloads. Write and optimize SQL queries and data models to support reliable and efficient data operations. Improve overall platform scalability, performance, and reliability across frontend and backend systems. Maintain clean architecture, modular services, and production-grade code quality. Debug, troubleshoot, and resolve issues to ensure codebase stability and long-term maintainability. Collaborate with a small, senior remote team to deliver features quickly while maintaining high engineering standards.

What We Look For

Advanced experience with React, including building scalable, maintainable UI systems with Next.js and TypeScript. Expert-level experience with FastAPI and building production-grade Python APIs. Advanced Python skills, including experience with concurrency, asynchronous programming, and performance optimization. Intermediate SQL skills, including query writing, debugging, and basic database performance tuning (not tied to a specific database like PostgreSQL). Strong frontend fundamentals and experience building clean, maintainable UI systems (e.g., Tailwind or similar CSS frameworks). Experience integrating APIs and building service-oriented architectures. Practical experience deploying or maintaining services in AWS environments. Clear thinker, strong communicator, and collaborative team player.

Nice to Have

Experience working with LLM APIs or AI-driven product features. Exposure to prompt engineering, AI workflows, or automation pipelines. Familiarity with agentic systems, multi-step reasoning, or tool-using models.
