Full Stack Developer

A late-stage (Series D), well-funded product company is building a brand-new, fully-remote engineering team in Poland.

We're looking for talented Full Stack Engineers who can build high-quality, scalable applications using TypeScript, React, and modern backend frameworks. You'll work closely with product, design, and other engineers to deliver features end-to-end. While financial markets experience is a plus, it is not required - strong engineering fundamentals matter more.

We are open to candidates who specialize in only front-end or only back-end development, as well as true full-stack engineers.

What You'll Do

• Design, build, and maintain production-grade applications using TypeScript across the stack.

• Develop intuitive, performant user interfaces using React and modern front-end tooling.

• Build and maintain backend services, APIs, and integrations (Node.js / TypeScript).

• Collaborate with product managers and designers to translate requirements into technical solutions.

• Write clean, testable, maintainable code with strong attention to performance and reliability.

• Participate in code reviews, architecture discussions, and continuous improvement initiatives.

• Troubleshoot issues across the stack and contribute to a culture of engineering excellence.

Required Skills

• Strong proficiency in TypeScript.

• Experience with React for front-end development.

• Experience with Node.js, server-side TypeScript, or similar backend frameworks.

• Solid understanding of modern software engineering practices: testing, CI/CD, version control, code reviews.

• Ability to work in a fast-paced, collaborative environment.

Nice to Have

• Experience working in financial markets, fintech, or trading systems.

• Familiarity with cloud platforms (AWS, GCP, Azure).

• Experience with microservices, event-driven architectures, or distributed systems.

• Exposure to data visualization libraries or real-time data applications.

• Experience with performance optimization on either the front-end or back-end.
