Senior Software Engineer (Golang)

As a Senior Software Engineer at Teya, you'll play a crucial role in shaping our technology platform and driving innovation across Europe. Working within a platform team, you'll design, develop, and maintain core APIs and event-driven services that power merchant data, subscriptions, and lifecycle management. Your work will be consumed by product teams across Teya, so you'll focus on reliability, performance, and ease of integration at scale. Your contributions will directly impact our merchants' success in an increasingly competitive landscape.

What You'll Do

• Build Platform Services: Take ownership of features throughout the full development lifecycle, designing and maintaining clean, secure, well-tested code that supports critical business needs with focus on scalability and reliability
• Design APIs & Event-Driven Systems: Create well-versioned APIs (REST/gRPC) and asynchronous workflows (queues, streams, webhooks) that other teams can easily consume, with strong focus on backwards compatibility, idempotency, and robust failure handling
• Work with Cloud Infrastructure: Collaborate with platform teams using cloud-native infrastructure (AWS, Kubernetes, Terraform, Helm) to ensure services are observable, secure, and easy to operate
• Enable Other Teams: Partner with engineering teams across Teya, gathering feedback and translating it into platform capabilities that accelerate their roadmaps. Collaborate with product, design, data science, security, and operations
• Mentor & Drive Quality: Participate in code reviews, mentor developers, define best practices, and contribute to CI/CD improvements while staying updated with trends in software engineering and fintech
