About the role

Senior Software Engineer — Agentic Coding (AI Training)

About The Role

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: Alignerr

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

Why Join Us

Work at the absolute frontier of agentic AI — one of the most exciting areas in technology today

Collaborate on cutting-edge projects alongside leading AI research labs

Fully remote and flexible — work when and where it suits you

Freelance autonomy with the depth and challenge of meaningful, high-impact engineering work

Your expertise directly shapes how AI agents write software — influencing tools used by millions of developers

Ongoing learning exposure to state-of-the-art large language models and autonomous systems

Potential for long-term engagement and contract extension as projects scale
