This role is ideal for engineers with strong fintech experience who enjoy shipping secure, high-impact mobile solutions. Responsibilities and duties
- Develop and maintain React Native iOS and Android mobile applications for fintech products.
- Integrate with payment providers and banking APIs (Stripe, Adyen, open banking, PSD2).
- Collaborate with cross-functional teams, including Product, Design, and QA, to deliver high-quality features.
- Implement secure, reliable, and scalable solutions, including risk/fraud prevention mechanisms.
- Contribute to CI/CD pipelines, code reviews, and support QA automation efforts for mobile and API testing.
- Experience in fintech software development, with at least 3+ years in React Native (iOS/Android).
- Solid background in fintech/banking products (payments, wallets, lending, BNPL, card, or banking operations).
- Hands-on experience integrating payment providers (ideally Stripe, Adyen, PayPlug, or similar).
- Experience working with banking/financial APIs (open banking, PSD2, or custom bank APIs).
- Good understanding of security, risk, and fraud detection concepts in financial products.
- Strong knowledge of TypeScript/JavaScript, REST/JSON, and CI/CD.
- Experience working in cross-functional product teams (Agile/Scrum) closely with Product, Design, and QA.
- Experience setting up or contributing to QA automation (mobile UI/E2E tests, API tests).
- Experience with risk/fraud systems, scoring engines, or rule engines.
- Experience with high-availability and high-load systems.
- A decent salary level which allows you to think about our mutual success and not about tomorrow.
- Flexible working hours. You create your own schedule.
- Possibility to work remotely. You prefer home office or traveling around? Easy, that's exactly how we operate.
