About Scalar:

Building on a great API is one of the best feelings in software — every interface you want is right there, and it all just works. Building on a bad one is the opposite: out-of-date docs, no SDK in your language, no MCP server. We started Scalar to fix that.

We're a small team (around ten engineers and designers) who wear a lot of hats and obsess over our craft. We think every company deserves Stripe-level docs, SDKs, and MCP servers from day zero — not just the ones with a platform team to build them. Open-source is in our DNA: our whole team contributes to and maintains repositories across the API ecosystem, including the standards everyone relies on, like OpenAPI.

We keep things lean and move without layers of process — engineers pick up problems, talk to each other, and ship. We're looking for owners with high agency: people who see what needs doing and do it. If you do your best work with a lot of autonomy and very little ego, you'll feel at home here.

The role

You'll own the platform that every other Scalar product runs on — the services, infrastructure, and internal tooling behind Docs, SDKs, the API Client, and Agent Scalar. This is one of the most load-bearing roles on the team: when you make the platform faster and more reliable, everyone ships faster.

Our infrastructure is real software, not config soup. We run a TypeScript monorepo on GCP, and our infrastructure-as-code is Pulumi written in TypeScript — so platform work here is engineering, not just YAML.

About Scalar:

The role

You'll work across the entire product surface — Docs, SDKs, the API Client, and Agent Scalar (our MCP servers) — shipping features from the API all the way to a polished UI. This is a high-ownership role for someone who likes to take something from an idea to production and out the door, then keep making it better.

As a senior engineer, you'll also raise the bar for the people around you — through code review, design discussions, and good defaults — without becoming anyone's manager.
