Stand up both app shells with CI, signing, distribution and crash reporting, and make the handoff flow clickable.
OPEN ROLE / PLATFORM / 03 OF 05
Senior Mobile App Developer, iOS and Android
Put terminal intelligence into staff pockets: handoff, fleet operations and companion surfaces on both platforms.
THE ROLE / WHAT YOU OWN
About this role.
When a terminal hands a visitor to a human, that human is holding a phone. As our senior mobile developer you build the native iOS and Android apps around the fleet: the staff handoff app that receives context from an agent, the operations app that watches every terminal, and the companion surfaces that continue a journey from screen to pocket.
You are the first dedicated mobile hire, so you set the architecture, the tooling and the bar. The apps must survive venue reality: patchy Wi-Fi, shared devices, loud floors and staff who have thirty seconds, not three minutes.
THE RAMP / NO WARM-UP LAPS
Your first 90 days.
Every role here starts with real work on the live product. This is the ramp we will agree on together, and the pace we hire for.
Take the staff handoff app live in a pilot venue: real context, real staff, thirty-second resolutions.
Put fleet operations in the pocket: terminal health, alerts and remote actions on both platforms.
RESPONSIBILITIES / THE WORK

- 01
Architect and build the native iOS and Android apps from the first commit

- 04
Make flows offline-tolerant for venue floors with unreliable connectivity
- 05
Implement enterprise auth: single sign-on, role-based access and audit for venue staff
- 06
Build companion journeys: QR continuation from terminal to phone, routes and status in the pocket
- 07
Own mobile CI/CD, store releases and enterprise distribution

THE CULTURE / DAY TO DAY
How we work.
EVIDENCE OVER OPINION
Demos, harnesses and floor tests settle debates. The best argument in the room is a measurement.
WEEKS, NOT QUARTERS
Work ships to a real floor fast. You will watch a stranger use what you built this month.
SMALL AND SENIOR
No layers, no committees. Five hires, two founders, one room when it matters.
REAL FLOORS
We test in public: noise, glare, hurry and all. If it works there, it works.
WHAT WE OFFER / STRAIGHT TERMS
€7,500 to €11,000 per month.
Depending on experience, with founding-team equity and profit sharing on top. We are a startup: the band is transparent, the upside is real and the ownership is yours.
- €7,500 to €11,000 per month, depending on experience, the same transparent band for every open role
- Founding-team equity: you own a piece of what you build
- Profit sharing once the machines are earning
- Senior ownership of a whole layer of the product, with direct access to both founders
- Amsterdam base with hybrid flexibility, plus time on real venue floors
- The hardware and tools you need, without a procurement fight
APPLY / PLATFORM
Tell us what you would build first.
Twelve months from now, venue staff open your app more often than their email. Send a short note with the apps you shipped, on both stores, and the hardest production incident they survived. A conversation with a founder follows within days.
