React / React Native Engineer

About Tradevest
Tradevest is a BaFin-licensed digital financial infrastructure provider headquartered in Munich, Germany. We deliver banking-as-a-service solutions that enable trading, custody, and management of traditional securities, cryptocurrencies, and tokenized assets — all through a single integrated platform. Our clients include banks, wealth managers, neobrokers, and fintechs across Europe.
Our IT development hub is based in Warsaw, where our engineering team meets in the office twice a week. We maintain a hybrid work model because we genuinely believe that in-person collaboration helps us build better products and stronger teams. We're growing rapidly, building serious financial platforms while keeping a relaxed, professional atmosphere where engineers have real ownership over what they build.

What you'll do
- Develop and maintain front-end applications across multiple initiatives — internal web apps, public-facing web platforms, and existing Android/iOS mobile apps
- Work using Typescript within a React and React Native stack, delivering polished user experiences for financial products
- Make sound architectural decisions autonomously while collaborating with experienced colleagues for validation and feedback
- Navigate and improve existing codebases — we need someone who enjoys bringing order to complexity, not just greenfield development
- Contribute to the full development lifecycle from feature design through deployment

What we're looking for
- 2-4 years of experience with a solid, demonstrable understanding of React and React Native
- Ability to work autonomously and make informed architectural decisions — this role requires ownership, not hand-holding
- Experience building and shipping both web and mobile applications
- Comfort working with existing codebases — reading, understanding, and improving code others have written
- A problem-solving mindset — you enjoy challenges and aren't discouraged by complexity
- Good communication skills for collaborating with the team and consulting on technical direction

Nice to have
- Familiarity with state management solutions (Redux, Zustand, MobX, or similar)
- Knowledge of CI/CD pipelines for web and mobile deployments
- Prior experience in fintech or other regulated industries
- Experience with app store submission processes (Google Play, App Store)

What we offer
- Hybrid work model — 2 days/week in our Warsaw office, rest remote
- 20 days PTO on B2B
- Variety of front-end challenges — internal tools, public platforms, and mobile apps, all within one role
- Autonomy with support — make real decisions backed by an experienced team
- A team that values engineering growth — we invest in building competences, not just shipping features
- Relaxed yet professional culture in a rapidly growing company
- Flex-time arrangements
