Description

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.

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. Need to be based in Poland 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.
