Role Description
Mercor is seeking software engineers to support one of the world’s leading AI labs in advancing code understanding and reasoning capabilities for next-generation machine learning models.
In this role, you’ll engage in real-world engineering work:
- Analyzing large, production-grade repositories to create and evaluate technically challenging coding questions.
- Systematically exploring multiple modules and connecting related functions across files.
- Assessing how advanced AI systems reason about architecture, data flow, and performance.
Your ability to reason from evidence: citing specific files, functions, and line numbers will directly influence how these AI models learn to think like expert engineers.
Qualifications
- 4+ years of elite software engineering experience at top-tier startups, quantitative trading firms, hedge funds, or similar high-performance environments.
- Experience using coding agents or LLMs as part of your engineering workflow (e.g., Copilot, Claude, GPT-4, or Replit Agents).
- Computer Science degree from a leading university or equivalent practical expertise.
- Fluent in Python and JavaScript/TypeScript, and can comfortably read Java, Go, or other modern languages (Rust, C++, C#).
- Demonstrate systematic exploration, examining multiple files and dependencies before forming conclusions.
- Practice evidence-based reasoning, grounding answers in specific code references rather than assumptions.
- Excel at cross-file synthesis, connecting distributed logic to explain how systems work end-to-end.
- Show strong architectural understanding, identifying patterns, abstractions, and design choices in complex codebases.
- Display intellectual honesty, acknowledging uncertainty when information is incomplete or ambiguous.
- Write clear, structured technical documentation, and communicate insights precisely and persuasively.
Requirements
- Ability to work across diverse systems, including web APIs, backend services, CLI tools, data processing pipelines, frontend applications, and DevOps tooling.
- Experience with security, observability, and performance-critical architectures.
Engagement Details
- This project will be a high-impact 24-hour sprint launching in the next 1–2 weeks.
- Compensation: Task-based pay (top performers previously earned $1,000+ during the sprint).
- Classification: Hourly contractor through Mercor.
- Payment: Weekly payouts via Stripe Connect.
