Join Checkly as a Senior Backend Engineer and empower developers to own and ensure application performance and reliability - from pull request to post-mortem!

Checkly helps engineers build reliable products by unifying testing, monitoring and observability. OpenTelemetry, Playwright, and Monitoring as Code are our foundation for unifying performance and reliability.

Our tech stack is Vue.js, Node.js, TypeScript, Postgres, ClickHouse and AWS. We ship to prod all day, every day. We practice Agile (not scrum) and take pride in good documentation and good looking products.

We’re 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!

Thousands of developers—teams at 1Password, CrowdStrike, Render, LinkedIn and Vercel included—trust Checkly to keep their apps running smoothly. In 2024, we raised $20M in Series B funding from Balderton, CRV, and Accel to take things to the next level.

We care about building a team where people of all backgrounds are encouraged to do their best work. To achieve this we built a flexible, remote-first and async-first startup environment with inclusive benefits and full transparency about how we pay.

What you'll do

Harden & expand our backend

Our backend runs on Hapi.js, Golang and a mix of AWS and bare metal server monitoring infrastructure, distributed around the globe. We ran over 2.5 billion checks already and are ramping up for a lot more.

To give you a clear idea of what the job could entail, here are some examples of the work we’ve done lately or will start soon:

Implement a custom playwright reporter that allows customers to send test results from their CI runs into Checkly.
Work with infra to deploy our own Clickhouse instance to capture check run logs and metadata. Design and implement an API on this datastore that allows customers to run reports on their check runs.
Work with a customer to hunt down a bug that lets certain checks fail in their private location infrastructure.
You will spearhead an AI Agent prototype to that allows customers to generate Playwright tests for their existing codebase.
You'll work on scaling our current backend platform to meet the demands of our growing business, and participate in our on-call rotation to keep everything running smoothly around the clock.

What you should have

You have deep experience in building applications in a professional product (SaaS) environment, ideally with TypeScript. (Go would be a plus.)
You’re exited about developer tooling, and Playwright.
