We are currently looking for a Senior Full Stack Engineer to join our growing Web Applications

team. reporting to the Engineering Manager, you’ll work on complex projects that span both

front-end and back-end, with an initial focus on web infrastructure for our FastAPI and Next.js

platform. In this role, you’ll optimize our build and deployment strategy for the front-end, including

designing dynamic bundling approaches (e.g., per-customer builds, code splitting, tree-shaking) and

improving performance across the stack through profiling, analysis, and optimization of both

front-end rendering (Core Web Vitals, TTFT) and back-end async workflows.

You’ll also contribute to the scalability of our FastAPI services, enhance our async programming

practices, and support the evolution of SOA and microservice architectures. On the front-end, you’ll

partner with product and design teams to integrate and extend our design systems and component

libraries, ensuring accessible, reusable, and performant UI components. Finally, you’ll collaborate

closely with the Security team to proactively identify and remediate vulnerabilities in dependencies,

libraries, and web infrastructure.
