About Assertis
Assertis is a profitable, privately-owned company building software for public transport — journey planning, rail ticket retailing, and real-time information. We've been around for 25 years: lean, product-focused, and growing.
Our APIs handle over 1 million journey searches daily and sell £200m worth of UK train tickets each year — about 5% of all train tickets sold online in the UK. We compete successfully with much larger companies and are well-known for driving innovation in the rail industry.
We're a distributed team across the UK, Poland, and Italy. On average, our technical team members have been with us for five years. We value autonomy, accountability, and collaboration.
What we're building
Now we're building a new mobile app — a greenfield React Native project for iOS and Android. We're looking for an experienced React Native developer to lead this build. You'll be hands-on writing code daily while working closely with our frontend team (two React developers and a designer), backend developers, and testers to create a consistent, high-quality experience across web and mobile.
What you'll do
- Build and ship a production React Native app from scratch
- Own technical decisions on architecture, tooling, and patterns
- Collaborate with the existing frontend and backend teams on shared design systems and API integration
- Work directly with our in-house API — no third-party guesswork
What we're looking for
- Strong React Native experience with shipped apps on both iOS and Android
- Ability to build polished, performant mobile experiences
- Comfortable communicating in English — daily collaboration happens in English across a distributed team
We're not counting years of experience. Show us you can build good apps.
What we offer
- Long-term role — we're building for the future, with a focus on continuous learning and improvement
- 100% remote, anywhere in Europe
- Semi-flexible hours
- B2B contract, 20,000–25,000 PLN/month
- Equipment provided
- Conference budget
- Small team where you're close to decisions and have real impact on how things are built

🔴
lead this build
Oczekuje się, że będziesz samodzielnie podejmować kluczowe decyzje techniczne dotyczące nowego projektu, a nie tylko wykonywać polecenia.
🔴
Own technical decisions on architecture, tooling, and patterns
Masz pełną odpowiedzialność za wybór technologii i sposobu budowania aplikacji, co może oznaczać konieczność szybkiego uczenia się i obrony swoich wyborów.
🟡
hands-on writing code daily
Pomimo roli lidera, będziesz spędzać dużo czasu na pisaniu kodu, co może ograniczać czas na inne aspekty roli.
🟡
greenfield React Native project
Projekt od zera, co oznacza brak istniejącego kodu i potencjalnie więcej nieprzewidzianych wyzwań.
🟢
no third-party guesswork
Masz bezpośredni dostęp do wewnętrznego API, co eliminuje problemy z integracją zewnętrznych usług, ale wymaga dobrej komunikacji z zespołem backendowym.
