(Fully remote, async-first, DevTool SaaS, 32-40h/week, time zones: UTC-3 to UTC+3)_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 adaptable, remote-first and async-first startup environment with inclusive benefits and full transparency about how we pay.

Your Team:
You'll join Team Tree, we handle enterprise enablement. That means our work cuts across the entire platform and touches areas such as uptime monitoring (TCP, DNS, URL, ICMP), Private Locations, RBAC, entitlements, and multi-account management. Everything that makes Checkly work for large organizations.

We are a small team with high autonomy. Enterprise work means priorities can change, so we keep plans loose and move fast when they do. You'll own problems end-to-end and ship things that unblock real customers.

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
