How to Get a Job Building Developer Tools

Getting your first dev-tools job is mostly a portfolio + positioning game. Unlike generic SWE roles where coding-interview performance dominates, dev-tools hiring managers care about whether you can ship a tool other developers actually want to use — and your public artifacts make or break the case.

This guide is the complete playbook: which companies hire for dev-tools, what hiring managers look for, the fastest path for career switchers, and the portfolio + interview prep that closes offers.

Companies that hire for developer tools roles

Categorized by likelihood of hiring + scale of the team:

• Big tech with named DPE/DevX teams: Google (Engineering Productivity), Meta (Developer Infrastructure), Microsoft (Developer Velocity), Amazon (Builder Tools), Apple (Internal Tools), Stripe (Developer Productivity), Shopify (Developer Acceleration), Airbnb (Tooling), Netflix (Productivity Engineering). Tier 1 comp.
• Dev-tools companies (the product IS the tool): GitHub, GitLab, JetBrains, Vercel, Netlify, Cloudflare, Datadog, Sentry, HashiCorp, Confluent, MongoDB, Posthog, Linear, dbt Labs, Supabase. Comp varies; mission alignment high.
• AI labs + AI-tooling startups: Anthropic, OpenAI, Cohere, Replicate, LangChain, Cursor (the Anysphere team), various YC AI startups. Tier 1 comp at the labs; high upside at startups.
• Mid-size companies with platform teams: Stripe, Uber, Lyft, DoorDash, Airbnb, Square, Mercado Libre, Booking.com, Spotify (the Backstage team is the famous example). Strong DPE budgets.
• Open-source-heavy companies: Red Hat, Canonical, GitLab, Hugging Face, Sourcegraph, Postman. Often hire OSS contributors directly.

Filter on: roles that explicitly say “Developer Productivity,” “Developer Experience,” “Platform Engineer,” “Build Engineer,” “Internal Tools”, or “Tooling Engineer”.

What hiring managers look for

Public hiring posts and informal interviews with dev-tools hiring managers consistently surface five things:

1. Public artifacts. A GitHub profile with at least 1–2 dev tools you’ve shipped (your own or substantial OSS contributions). This is the single biggest signal — it shows you can finish things and that you have taste.
2. Empathy for users. Tools fail when authors don’t feel their users’ pain. Interviews probe this with “walk me through how you’d roll out tool X to a 50-engineer team.”
3. System thinking. Dev tools touch builds, CI, deploy, runtime. Hiring managers test for the ability to reason across the whole pipeline, not just the slice in front of you.
4. Documentation + communication. Tools live or die on docs. A candidate who writes a clean README and clear PR descriptions stands out.
5. Pragmatism. Dev tools is a discipline of solving real problems with the simplest possible tools. Over-engineering is a red flag; opinionated but proportional design is a green flag.

Getting your first dev-tools job

The fastest paths from regular dev → dev tools (in order of leverage):

1. Internal rotation. Ask your current employer for a 6-month rotation onto the platform/DevX team. You keep your salary, build the portfolio, and apply externally with the title in hand. This converts faster than any external job search.
2. Ship one OSS dev tool. 8 weeks of nights and weekends. Real tool, not a toy. Use our idea scorer to pick something high- signal. Apply to dev-tools roles with the GitHub link in your application.
3. Substantial OSS contributions to dev-tool projects. Pick 1-2 projects you actually use. Submit non-trivial PRs (not typo fixes; real features, documentation overhauls, or test-coverage drives). Reference them in applications.
4. Conference talk or technical blog series. Write 6 posts on a dev-tools topic (your CI/CD migration, your build-system optimization, your internal tool pivot). Builds public credibility. Some companies (Stripe, Cloudflare) explicitly recruit blog authors.
5. Cold outreach to teams you admire. Find DPE/DevX leads on LinkedIn, send a 100-word note referencing one specific thing they’ve shipped, attach your GitHub. ~10% reply rate; better-than-zero.

Interview prep that works

Dev-tools interviews are different from generic SWE loops. Expect:

• System design with developer-tools framing. “Design an internal feature flag service” rather than “design Twitter.” Practice these specifically — the constraints differ.
• Product / UX questions. “Walk me through the rollout plan for a new internal tool to 200 engineers.” “How would you handle backwards-compatibility for X?” Prep stories from your past work.
• API design. “Design the API for [some dev tool].” Read aip.dev (Google’s style guide) and Stripe’s API design blog before the loop.
• Coding rounds: still happen, but often weighted lower at senior+ levels. Practice CLI-style problems (parse a command, walk a directory) rather than only LeetCode.
• Trivia about specific tools. Know your stack — if applying to a Bazel team, brush up on Bazel. If a CI/CD role, know GitHub Actions / GitLab CI / Buildkite differences.

The portfolio link in your resume + clear specific stories from past dev-tools work matter more than LeetCode pattern memorization for these roles.
