The Opportunity

We're looking for a full-stack Software Engineer to join our Developer Experience team in Porto and help build the next generation of engineering velocity inside Superhuman Docs. The ideal candidate is energized by making other engineers faster and happier, brings strong communication and product sense alongside their engineering skills, and thrives across a broad, fast-moving stack. This is a high-autonomy, high-impact role on a foundational team that moves fast from idea to production.

Where our central Engineering Platform team builds the org-wide paved paths and tooling, you'll be the embedded partner and spokesperson inside Superhuman Docs—bringing that central work to life in the codebase, solving what you can autonomously, and carrying the team's real-world needs back to the platform org so global and local priorities stay aligned. Much of the work is greenfield: you'll stand up new tools, workflows, and practices from scratch, in close partnership with the platform team and deeply embedded with the engineers you serve.

The impact is direct and measurable. The Docs codebase sees hundreds of pull requests every week, so your improvements compound immediately—shave a few seconds off a build and you save thousands of seconds of compute across the team every week, easy to quantify and easy to feel. You'll work across a codebase that is part monolith and part microservices, with a high volume of releases, in a role where communication is half the job and curiosity is rewarded daily.

As a Software Engineer on this team, you'll be at the heart of how Superhuman Docs gets built.

In this role, you will:

• Serve as the embedded Developer Experience partner and spokesperson for the Docs business unit—implementing what the central platform team builds within the BU’s context, resolving issues autonomously where you can, and aligning with the central team where you can’t.
