Our client is a rapidly growing FinTech SaaS company transforming the way financial institutions manage complex trading and investment workflows. Following significant investment and continued international expansion, they're embarking on a complete rebuild of their technology platform using modern engineering practices, AI-assisted development and cloud-native architecture. As part of this journey, they're looking to hire a talented TypeScript Software Engineer to help shape the future of their flagship platform.
This is a genuine opportunity to build software from the ground up rather than maintain legacy systems. Working within a highly collaborative engineering team, you'll develop scalable applications using TypeScript, modern JavaScript frameworks and cloud technologies, while influencing architecture, engineering standards and best practice from day one. The business has an AI-first engineering culture, encouraging developers to use tools such as GitHub Copilot and modern AI workflows to accelerate delivery while maintaining exceptional software quality.
Successful candidates will have strong commercial experience with TypeScript, JavaScript and modern software engineering principles. Experience with Node.js, React, Next.js, REST APIs, PostgreSQL, Docker, Kubernetes, microservices and cloud platforms such as AWS or Azure would be highly advantageous. Exposure to Agile methodologies, CI/CD pipelines and automated testing is desirable. Most importantly, you'll be someone who enjoys solving complex problems, takes ownership of your work, and is excited by the chance to build innovative software that delivers genuine business value.
