Role Overview ??
As a Senior Fullstack Engineer, you will work across frontend and backend areas that support Benifex employee experience products, mobile app, and platform look and feel.

The team is responsible for operational continuity, technical stability, and continuous improvement beyond the product roadmap, which means the work often involves balancing new development with careful maintenance, refactoring, and production reliability.

This role suits someone who enjoys complex domains, established systems, and end-to-end ownership. You will contribute to frontend development in React, TypeScript, and Angular, while also designing and maintaining backend services, APIs, and integrations using Java, Spring/Spring Boot, and SQL.

We are also on a journey to use AI more deliberately in our daily engineering work. We are looking for someone who has practical experience with AI-assisted and agentic coding workflows, or who wants to keep exploring how these tools can help us move faster, improve quality, understand complex codebases, and reduce repetitive work without lowering our engineering standards.
