run:ai, is looking for a senior software engineer to build the tools that help engineers develop, validate, and contribute software with confidence. as we expand our open-source ecosystem and adopt agentic development, you'll shape how contributions are tested and integrated, improve feedback for developers, and help protect our codebase and internal assets. you'll work across Developer tooling, compatibility validation, scale testing, and ai-assisted contribution workflows, building infrastructure that supports both our engineering teams and the wider open-source community.
what you'll be doing:
build Developer tools and ci workflows that simplify development, testing, and contribution for internal engineers and open-source contributors.
develop compatibility validation infrastructure that verifies run:ai across supported software versions and environments.
build scale-testing and performance-regression infrastructure that produces repeatable results and actionable diagnostics.
develop workflows for agentic prs, including automated evaluation, testing, and controls that support effective human review.
partner with engineering, DevOps, and security teams to enable external contributions while protecting credentials, internal systems, and code integrity.
own projects from technical design through rollout, measuring their impact on Developer productivity and software reliability.
Requirements: what we need to see:
a degree in Computer Science or a related field, or equivalent practical experience.
5+ years of software engineering experience, including building Developer tools, shared libraries, or engineering infrastructure.
strong programming skills and the ability to design maintainable software used by other engineers.
practical experience developing ci/cd pipelines, automated testing frameworks, and git-based development workflows.
ability to diagnose unreliable tests, slow feedback cycles, and recurring development friction, and address their underlying causes.
experience delivering and maintaining reliable software, including testing, debugging, and operational support.
ability to use ai development tools effectively and evaluate generated code for correctness, security, and maintainability.
clear communication, sound engineering judgment, and the ability to collaborate across team boundaries.
ways to stand out from the crowd:
experience maintaining open-source projects or improving external contributor workflows.
experience building tooling for coding agents, evaluating ai-generated changes, or automating code review.
background with compatibility matrices, performance benchmarking, or scale-testing frameworks.
familiarity with secure ci practices, dependency integrity, and running tests on untrusted contributions.
a track record of measurably improving Developer productivity and software reliability.
