As a Sr. Full-Stack Engineer at Qover, you’ll take ownership of complex features end-to-end — from design discussions through implementation, deployment, and monitoring.
You’ll contribute to architectural decisions and help evolve our platform as we scale.
Use AI thoughtfully — in development and beyond: We encourage responsible use of AI-assisted tools to improve productivity, code quality, and documentation.
You’ll also have space to explore where emerging AI capabilities could meaningfully enhance our product, in collaboration with engineering and product leadership.
Design and evolve scalable services and APIs: You’ll build and maintain Node.js services and React applications that support high availability, strong performance, and international scale.
Build for performance and reliability: You’ll design data models in MongoDB, optimize API performance, and ensure services are observable, testable, and resilient.
Design with security and privacy in mind: You’ll implement secure authentication and authorization flows, protect sensitive data, and follow best practices for compliance and data protection.
Contribute to a strong engineering culture: Through code reviews, knowledge sharing, and mentoring, you’ll help raise the technical bar across the team.

Strong professional experience building and operating production systems (typically 5+ years).
Strong engineering fundamentals and architectural thinking. We operate a microservices-based platform using Node.js, React, and MongoDB. Experience with distributed systems, service boundaries, and API design is important. If you come from ecosystems like Java, C#, Go, or Python and have successfully worked in production systems at scale, we value your ability to adapt.
Strong sense of ownership and accountability. You take responsibility for the quality, security, and maintainability of what ships — and you provide thoughtful, high-signal code reviews.
Experience designing and maintaining robust RESTful APIs.
Strong Git skills and familiarity with CI/CD pipelines and automated deployments.
Experience integrating third-party services and managing data consistency across systems.
Experience working with cloud environments (GCP preferred). Familiarity with containerization and orchestration (Docker, Kubernetes) is a plus.

Hybrid & remote-friendly: We welcome candidates across Europe. Our Brussels office is a key collaboration hub, and many team activities take place there, but we support flexible remote arrangements and up to one month per year working from anywhere globally.
A Hub When You Want It: Full access to our dedicated space at WeWork in Brussels (Rue du Commerce 31) for when you want collaborative whiteboard sessions or legendary team events on the terrace.
Exceptional Culture: A deeply collaborative, inclusive community where you are valued for exactly who you are, regardless of nationality, gender, age, sexual orientation, disability, or background.
Massive Growth: You’ll join during a high-growth phase, with opportunities to influence our core platform architecture, backend microservices, and overall developer experience.
