Careers

Engineers who want the whole problem

We hire people who can own a feature from scoping to store release, and who will say when something should not be built.

Why join

What it is actually like

Remote, async-first

Two hours of overlap, written decisions, no standup theatre.

Senior-only room

You will not be babysitting a junior bench or rewriting someone's prototype every sprint.

Real product work

Apps with users and revenue attached, not internal demos.

Paid from the trial on

The trial task is paid work, and it is scoped to a few hours, not a weekend.

How we hire

Three steps, about two weeks

Every application is read by a person. Shortlist → screen call → paid trial task.

01

Apply

One form, one CV. No account to create, no fifteen-field questionnaire.

02

Screen

A 30-minute call about work you have actually shipped. We read your CV before the call, not during it.

03

Paid trial task

A small, scoped, paid piece of real work. If it goes well, we talk terms that week.
