What if your software engineering expertise could define how the next generation of AI writes, debugs, and ships code on its own? We're looking for Senior Software Engineers in Seattle to work at the frontier of agentic AI — building, evaluating, and improving autonomous coding systems that can reason through complex problems, execute multi-step plans, and produce production-quality software with minimal human intervention.
Seattle is one of the world's premier engineering hubs, home to engineers who've built the systems powering the modern internet. This role channels that caliber of talent toward the most transformative challenge in software today: teaching AI to code autonomously.
This is a fully remote, flexible contract role. If you're a senior engineer who's excited about agentic AI and wants to work on problems that genuinely matter, we want to hear from you.
Organization: the hiring company
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week

What You'll Do
Design, build, and refine agentic coding workflows — systems where AI autonomously plans, writes, tests, and iterates on code
Evaluate AI-generated code for correctness, efficiency, security, and adherence to best practices
Create complex, real-world coding challenges and benchmarks to stress-test agentic AI capabilities
Provide expert-level feedback on AI reasoning chains, tool usage, and code output quality
Identify failure modes, edge cases, and areas where autonomous agents break down
Develop and improve evaluation frameworks, rubrics, and testing harnesses for agentic systems
Collaborate asynchronously with researchers and engineers working on large language models and AI agents
Work independently on task-based assignments at your own pace and on your own schedule
---
Who You Are
5+ years of professional software engineering experience — you've built, shipped, and maintained real systems
Proficient in one or more major languages: Python, JavaScript/TypeScript, Java, C++, Go, or Rust
Strong understanding of software architecture, design patterns, and system design principles
Comfortable reading, reviewing, and debugging code you didn't write — across diverse codebases and styles
Deep familiarity with modern development workflows: version control, CI/CD, testing frameworks, and code review
Excellent problem-solving and analytical thinking — you can reason through ambiguous, multi-step technical challenges
Clear, precise technical communicator who can articulate why code is good, bad, or broken
Self-directed and reliable when working independently without close supervision
Genuinely curious about AI, LLMs, and the future of autonomous software development
---
Nice to Have
Experience with AI/ML systems, prompt engineering, or LLM-based tooling
Familiarity with agentic frameworks (e.g., LangChain, AutoGPT, CrewAI, OpenAI function calling)
Background in developer tools, compilers, static analysis, or code generation
Experience evaluating or training AI models — RLHF, preference labeling, or similar workflows
Contributions to open-source projects or a strong public engineering portfolio
Knowledge of multiple programming paradigms and languages
