Remote Staff NA Developer Tools Robotics Senior Backend Developer Founder Staff Development

Requirements

• 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. • You can name a CI time you cut and the technique you used, and you've worked with at least one monorepo build system at depth. • You've integrated an eval framework into a real CI pipeline (at least one). • You write code with AI daily and have opinions on rules files and repo-level agent guidance. • Strong written communication. • Bonus: devcontainers or comparable cloud dev environments; custom lint-rule authoring; open-source developer-tools contributions. • On-site in San Francisco, in person, long days, high standards. 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. You'll build for an audience that notices immediately. The right person wants that pace and that scrutiny. • Compensation (OTE): $176,000–$253,000 cash (base + target performance bonus), plus competitive equity. • Location: San Francisco, in-office. Based here or willing to relocate. • Benefits: Uber commuter benefits; breakfast, lunch, and dinner provided; snacks and coffee stocked; free gym membership; health, dental, and vision. • Process: Founder call (15 min) → Tech Lead deep-dive (60 min, inner-loop / CI) → Super Day on-site → founder + Tech Lead offer. No committee. Best offer, first. • To apply: If you've cut a 20-minute CI to 4, or boot times from 45 minutes to 6, or shipped an eval suite engineers actually trust — send your resume, the numbers, and the playbook.

Responsibilities

• Cut CI build times - Monorepo tuning, incremental builds, remote caching. Target: CI <5 min on p95. • Cut CI build times • Own dev environment reliability - Local/staging/CI parity. Boot a working env in <10 min. Reproducible. Containerized. • Own dev environment reliability • Quarantine flaky tests - Detection, isolation, dashboard. Flaky tests get fixed or quarantined, never silently retried. • Quarantine flaky tests • Wire the eval stack into CI - Pre-merge gates · offline experiments · production trace monitoring • Wire the eval stack into CI • Ship PR preflight automation - The robot summary every PR opens with: services touched, tests run, missing tests, migrations, critical-path warnings • Ship PR preflight automation • Build internal developer-platform pieces - Service templates, scaffold generators, doc indexers, internal CLI commands • Build internal developer-platform pieces • You Might Be a Fit If… • You've shipped developer tooling / CI / build infra that other engineers actually adopted at a high-growth company • You can name a CI time you cut and the technique you used • You've worked with at least one monorepo build system at depth • You've integrated an eval framework into a real CI pipeline • You write code with AI daily and have opinions on rules files, repo-level agent guidance • You're 3–6 years into your career

Benefits

• $176K – $253K • Offers Equity • Offers Bonus • The Problem • 36 million businesses in America need insurance. 77% are underinsured. 40% have no coverage at all. We're building 90%+ AI-led commercial insurance distribution. ~1,000 new customers/month, 100x growth in a year, scaling toward Series B. • Our engineers and our coding agents both ship 5–10x faster than they did a year ago. Without rails - fast builds, reliable dev environments, merge queues, eval frameworks that catch regressions - that velocity quietly converts into rework, hotfixes, and weekend pages. • Engineers ship at the speed of the slowest part of the inner loop. Make the inner loop fast and trustworthy. • The Thesis • The fastest teams are not fast because they tolerate chaos. They are fast because the path from idea to production is short, trusted, and boring in the best way. At Harper, that path has to work for humans and coding agents. • You will build the loop engineers live inside every day: dev environments that boot, tests people trust, CI that gives signal, PR preflight that catches risk, and tooling that makes the right pattern easier than the wrong one. • OTE: $176,000–$253,000 cash compensation (base salary + target performance bonus) • Equity: competitive equity, so you share in the company you are helping build • Equity: • Location: San Francisco, in-office • Location: • Health, dental, and vision insurance • Team meals and snacks • The Process • Founder call (15 min) - Mission, pace, scope • Founder call (15 min) • Tech Lead deep-dive (60 min) - Inner-loop / CI conversation • Tech Lead deep-dive (60 min) • Super Day on-site - full-day simulation of working at Harper: dev-environment debug, CI design, code review, team context, and founder/CTO time • Super Day on-site • Founder + Tech Lead offer conversation - No committee. Best offer, first. • Founder + Tech Lead offer conversation • To Apply • If you've cut a 20-minute CI to 4, or boot times from 45 minutes to 6, or shipped an eval suite engineers actually trust - send your resume, the numbers, and the playbook.
