We do this by building an industry-leading incident management platform that allows companies around the world to consistently and quickly resolve incidents.

Some of the fastest-growing companies around the world such as NVIDIA, DoorDash, Uber, Canva, Tripadvisor, Squarespace and more rely on Rootly to power their critical incident management process. They obsess over our delightful enterprise-ready platform and unique partnership model. See why our customers have reviewed us 5 stars on G2.

Investors love Rootly. We are backed by some of the most respected funds in the world from Y Combinator to operators like the CTO of Dropbox and GitHub. We'd be happy to disclose our entire funding and profitability picture live during the interview. As a culture we relentlessly put transparency first. We conduct monthly financial reviews as a team so everyone has a pulse on the health of the business and publish what we are building in our weekly changelog.

About the Role

~1 min read

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.

Responsibilities

~1 min read

Instrument the delivery pipeline end to end so we know where time goes between merge and production.
Cut merge-to-production lead time and keep it down as the team and codebase grow.
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.
Track developer experience numbers like build time, deploy frequency, and change failure rate, and share progress openly.

We care about impact, ownership, and technical judgement. Degrees and big-name logos are not required. What matters is your ability to execute, influence, and teach.

Requirements

~1 min read

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 running CI systems at scale, and with deploy trains or merge queues.
Experience with test parallelization and test selection for Ruby or RSpec suites.
Experience building ephemeral or shared staging environments.
Experience with Ruby and Go.

By 6 to 12 months you will have:

Instrumented the pipeline end to end, with a shared dashboard for build time, lead time, deploy frequency, and change failure rate.
Meaningfully cut merge-to-production lead time, and kept it there as headcount and pull request volume grew.
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 new engineers shipping to production in their first week.

Backend: Ruby on Rails, PostgreSQL, OpenSearch, Redis, Sidekiq, AWS Lambda, ECS, Kafka, DynamoDB
Frontend: Turbo, Stimulus, ViewComponents
Infrastructure: AWS, Terraform (IaC), Datadog

We're not just another startup. 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.

Here's what you can expect when you join Rootly:

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.
A fast-moving, high-impact environment where your leadership and ideas directly shape the future of the company.

Our team is growing, and this is a newly created vacancy that we may hire more than one person to fill.

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.

If this sounds like the kind of challenge and opportunity you're looking for, apply now and let's build something great together.
