Developer Tooling Engineer

A team that keeps repeating the same manual steps across every project or every release has a tooling gap that's costing real hours, even if no single instance of it looks worth automating on its own. We build custom CLIs and internal developer tools targeted at your team's actual repetitive workflows, not a generic productivity suite you'll never fully adopt. This is for engineering teams whose onboarding, scaffolding, or release workflow depends on tribal knowledge and copy-pasted commands. You get a tool your team actually uses daily because it was built around their real workflow, with the source code handed over so it keeps evolving with you.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

  1. 1

    Shadow your team's workflow to find the specific repetitive steps costing the most real time.

  2. 2

    Build a minimal CLI or tool covering the highest-friction workflow and pilot it with a few engineers.

  3. 3

    Review the pilot tool's usability with the team and refine commands and output based on real usage.

  4. 4

    Finish the tool, document it, and hand off source code so your team can extend it going forward.

What You Get
