Build the software behind thousands of counters
Small, remote-first team across the US and Europe. Unusually direct feedback, and a product where the consequences of your work are visible the same day: if something you built is slow, a queue forms at a counter. That focuses the mind wonderfully.
Where we need help
Senior Platform Engineer
Own parts of the shared core - pricing, tax, sync, persistence - that every platform depends on.
Android Engineer
Build the till interface that cashiers use ten thousand times a week. Latency is the whole brief.
Backend Engineer
Multi-tenant data, event-sourced stock movement, sync conflict resolution and an API people build on. We share the stack once we are talking.
Product Designer
Design for people under time pressure on cheap hardware in bad lighting. Harder and more interesting than it sounds.
Implementation Specialist
Migrate real businesses onto SumPOS - data mapping, configuration, hardware and training, on site.
Customer Support Engineer
Answer the person whose printer stopped mid-rush. Technical enough to fix it, calm enough to be useful.
Four steps, no take-home marathon
A short conversation
Thirty minutes on what you have built and what you want next.
A real problem
A paid, time-boxed exercise from our actual backlog. No fictional puzzles.
A working session
We solve something together for two hours. It is the most honest signal either side gets.
An offer, quickly
Within a week of the last conversation, with the number and the reasoning behind it.
We pay for exercise time at your normal rate. Asking for unpaid work is a tax on people who cannot afford to give it away.
