Fully remote, async-first, DevTools SaaS, **h/week, time zones: They catch it first, in the pull request, in staging, or in the checkout flow at 3am, before a single user notices. We give developers and their agents the tools to own reliability the way they own their code: end-to-end tests and synthetic monitoring defined as code, powered by OpenTelemetry and Playwright, versioned and reviewed like everything else they ship. Here's the thing about *: AI agents and coding assistants are shipping more software, faster, than any team could review by hand, and more of it is breaking in ways nobody has seen before. is becoming an unanswerable question for a whole generation of AI-native software.

You will build reliability for this kind of software. Our stack is AI (Codex, Claude, use what you like best), Vue.js, TypeScript, Node.js, Golang, Postgres, ClickHouse and AWS. We practice Agile (not scrum) and take pride in good documentation and good looking products.

We are a remote-first startup that keeps things simple - low on meetings, high on productivity, and always shipping. If you love building cool things, working async, actually listening to and working with customers, and keeping it lean, you'll fit right in! You will actively use coding agents for full stack development, from exploring solutions and generating scaffolding to refactoring, test generation and debugging.

You will talk directly to the developers, DevOps and Site Reliability Engineering (SRE) teams who are on-call, debugging incidents, or wiring Checkly into production pipelines. Customer calls and the weekly support rotation are part of the job, not a distraction from it.



In a world where the cost of building software trends to zero, the hard part is picking what to build.

You will focus on real developer pain: flaky tests and flaky checks, unclear failures, noisy alerts. From shaping the initial idea, through implementation and rollout, to watching how it behaves in production. You have built and run production software.

You know the realities of operating software that people depend on: edge cases, incidents, regressions, and the need for observability and follow-up. You can look at a customer problem and reason about whether the thing we are about to build actually solves it. You work well without an office around you.

You are autonomous and self-motivated in a remote setup, and you still enjoy getting to know your colleagues and helping other people get unstuck. FULLY remote role, within the UTC-3 to UTC+3 time zones. You need to be able to travel to (other) European countries without having to wait for a visa appointment, for our annual kickoff, a team meetup or a conference.

If you do your best thinking out loud in a room full of people, you will miss it here. There is no separate QA team, no ops layer to hand things off to, and you are on the support rotation and the on-call rotation like everyone else. Remote-first, versátil work hours, async-first (low meeting, high productivity) and transparent culture Become part of a fast-growing, international, and remote team where your work matters, and your impact won't get lost in layers of bureaucracy. 27 days of paid vacation + your local public holidays Co-working budget or home office setup
