Position: Software Engineer (Builder Tools)

As a Software Engineer on the Builder Tools team, you will build and maintain the CI/CD infrastructure, internal tooling, and AI-assisted development workflows that every engineering team at Hadrian depends on
Your users are Hadrian’s engineers, and your job is to make them faster
That means owning shared pipeline libraries, reducing friction in the SDLC, making internal systems accessible to AI coding agents, and automating the work that slows teams down
The systems you build touch every engineer at Hadrian, and the improvements you ship show up immediately in how fast the company moves
Build and maintain CI/CD pipeline libraries that abstract build, release, and deployment events for use across multiple engineering teams
Design and build internal tools, APIs, and CLI utilities that reduce developer friction and automate recurring engineering tasks — dependency upgrades, credential rotation, routine maintenance
Help make Hadrian’s internal systems API-ready for AI coding agents; build harness tooling, context systems, and feedback loops that improve the quality of AI-generated contributions in our codebase
Instrument and monitor developer productivity systems; surface bottlenecks and measure the impact of tooling improvements through clear metrics
Partner with application development teams to identify needs, implement CI/CD best practices, and drive adoption of new tooling across the org
Join the on‑call rotation to support systems and services during production incidents; contribute to root cause analyses and postmortems
Participate in code reviews and author technical proposals that raise the engineering bar for the Builder Tools team

Proven ability to troubleshoot complex systems and resolve issues efficiently
A developer empathy mindset: you build tools that are easy to adopt, well-documented, and reduce toil rather than create it

Bachelor’s degree in Computer Science or related field, or equivalent experience
Experience with Docker and container orchestration (Kubernetes or similar)
5–8 years of software engineering experience, with at least 2–3 years focused on CI/CD, developer tooling, or build infrastructure
Hands‑on experience building and maintaining complex CI/CD pipelines and build infrastructure — pipeline-as-code, artifact management, multi‑environment deployments
Genuine curiosity and hands‑on experience with AI coding tools and agents — Copilot, Cursor, Claude Code, or similar — and opinions about what makes them work well in a real codebase
Experience building API‑ready interfaces or harness tooling for AI coding agents
Familiarity with Git Ops principles and workflows
Prior work on developer experience or engineering productivity programs
Experience with static analysis, automated PR pipelines, or code review tooling
Background in fast‑paced or scaling startup environments
