Software Engineer — Backend Coding Tasks (micro1)
What the work involves
micro1 is engaging Software Engineers with strong backend experience to author realistic, challenging coding tasks that AI models must solve — and to build the deterministic verifiers that grade them, accepting every reasonable valid solution and rejecting everything else. You'll work across feature implementation, bug fixes, codebase refactoring and performance optimisation, leaning on solid algorithms and data-structures fundamentals and a testing mindset. Compensation is output-based: experts are paid per task that meets the project specifications, and a minimum number of tasks must be submitted each week.
No prior experience in AI is required — your engineering judgement is what matters. Contractor, fully remote and flexible (~15 hrs/week).
What you'll do
- Create realistic, interesting and challenging coding tasks for AI to solve, spanning feature implementation and bug fixes
- Implement deterministic verifiers that accept reasonable valid solutions and reject everything else
- Design tasks around scalable services and APIs, debugging, performance work and automated testing
- Apply strong code-review instincts to keep task specs and reference solutions unambiguous
- Refactor and extend code across large-scale applications
- Identify and resolve software bugs and system bottlenecks in the problems you design
- Complete a short AI interview (~15–20 minutes) and any technical assessment without outside assistance
- Meet the minimum weekly task submission and start within 24–48 hours of onboarding
Requirements & eligibility
- Strong backend experience in Java, Node.js, Go, Rust, TypeScript, Python, C++ or similar
- A track record of building scalable services and APIs
- Comfort with debugging, performance work and automated testing
- Solid code-review instincts
- Strong understanding of algorithms, data structures and foundational computer science
- Experience with codebase refactoring and implementing complex features in large-scale applications
- Excellent analytical, problem-solving and technical communication skills
- English proficiency for instructions and written feedback
