About The Role
As a Senior Platform Engineer focused on Developer Experience, you'll own the path from a developer's laptop to production: CI, test infrastructure, deploy trains, and staging. You'll measure where engineers lose time, cut merge-to-production time, and make flaky tests rare. Product engineers are your customers. You'll work with our platform engineering leader and our QA team, and your work will give time back to every engineer at Rootly. As Rootly grows and AI speeds up development, more pull requests flow through the same pipeline every month, so the impact of this role compounds. Instrument the delivery pipeline end to end so we know where time goes between merge and production. Find and fix flaky tests at the source, and build tooling that catches new flakiness early.



Own our CI pipelines and deploy trains, including smoke gates and rollback. Untangle staging so teams stop waiting on each other to test changes. Improve local development and onboarding so new engineers ship in their first week.

What You'll Need
We care about impact, ownership, and technical judgement. Degrees and big-name logos are not required. 5+ years building software in production, with significant time on modern CI/CD (such as Buildkite, CircleCI, GitHub Actions, or Argo CD), build systems, or developer tooling. Hands-on experience running and speeding up CI pipelines for a large codebase. Experience diagnosing and fixing test flakiness and test infrastructure problems. A developer experience mindset: you treat other engineers as customers and measure whether your tools help them. Comfortable working in a large Rails monolith as well as in infrastructure. You write production-grade software, and you explain tradeoffs clearly to product teams and leadership. Experience with test parallelization and test selection for Ruby or RSpec suites. Experience building epoxy or shared staging environments. Experience with Ruby and Go. Instrumented the pipeline end to end, with a shared dashboard for build time,



lead time, deploy frequency, and change failure rate. Made flaky tests rare, with tooling that flags new flakiness before it spreads. Removed staging as a bottleneck, so teams test changes without waiting on each other. Got recent engineers shipping to production in their first week. Ruby on Rails, PostgreSQL, OpenSearch, Redis, Sidekiq, AWS Lambda, ECS, Kafka, DynamoDB Frontend: Infrastructure: AWS, Terraform (IaC), Datadog We're building something category-defining and want teammates who crave ownership, love solving hard problems, and thrive in a high-bar, high-impact environment. Competitive compensation and early equity in a fast-growing, venture-backed company. Comprehensive medical, dental, and vision coverage. 3 weeks of vacation, plus unlimited sick and mental health days, and a company-wide end-of-year shutdown to recharge. $500 stipend for home office setup. Unlimited token usage and access to AI tools. As we build out the team, we may use AI to support parts of our interview process, like reviewing assessments, but it's a tool that helps our people, not a substitute for their judgement. Accommodations are available on request at any stage of our recruitment process.
