About the role
- Engineers ship at the speed of the slowest part of the inner loop - and at Harper that loop has to run fast for humans and for coding agents, both of which now ship 5-10x faster than they did a year ago.
- The fastest teams aren't fast because they tolerate chaos; they're fast because the path from idea to production is short, trusted, and boring in the best way.
- It's a direct lever on the bet: the faster and more trustworthy the loop, the more judgment-into-compute work the whole org ships per week.
Responsibilities
- Own dev-environment reliability. Local/staging/CI parity, a working env booting in under 10 min, reproducible and containerized.
- Build the internal developer platform. Service templates, scaffold generators, doc indexers, internal CLI commands.
- 3-6 years building software, with developer-platform / CI-CD / build-infra / dev-environment experience that other engineers actually adopted at a high-growth company.
- Cut CI build times.
- You'll build for an audience that notices immediately.
Nice to have
- devcontainers or comparable cloud dev environments
- custom lint-rule authoring
- open-source developer-tools contributions.
- DX here is high-leverage and highly visible - when the loop is fast, twenty engineers and a fleet of coding agents move like a much larger org
- when it's slow, everyone feels it.
- The right person wants that pace and that scrutiny.
Compensation
- $176,000-$253,000 cash (base + target performance bonus), plus competitive equity.
Benefits
- Uber commuter benefits; breakfast, lunch, and dinner provided; snacks and coffee stocked; free gym membership; health, dental, and vision.
- Bonus: devcontainers or comparable cloud dev environments
