The opportunity

We are looking for an experienced Senior Backend Engineer to join our Foundation Engineering team. In this role, you won't just be building features for a single product; you will be crafting the very core services that power the entire Urban Sports Club ecosystem.

The Foundation team sits at the heart of our engineering organization. We are responsible for application-level, system-wide services that enable our multi-million user base to interact with our platform seamlessly. Your initial focus will be taking ownership of our critical Identity & Authentication services and our core Search backend , with exciting plans to architect and scale a centralized Notification service in the near future.

You will act as a force multiplier for our entire engineering department. By designing highly scalable, secure, and performant internal APIs and services, you will enable other product teams to build fast and deliver value to our users. If you love deep-diving into system design, solving complex architectural challenges at the application level, and working with Golang, this is the perfect place for you.

This position will be based in Berlin.

What you will do

Own Core System Services: Architect, develop, and maintain high-throughput, application-level foundational services, focusing initially on identity/authentication and our core search backend service.
Drive Technical Evolution: Design and implement future shared services that support our vision for scaling the platform.
Enable Engineering Teams: Build clean, robust, and well-documented internal APIs and developer tools that empower other product teams to build features rapidly and securely.
Write Exceptional Code: Deliver highly testable, maintainable, and secure Golang code, taking full operational ownership of the components your team develops.
Foster Best Practices: Actively participate in the Urban Sports Club backend cluster, championing strong system design, modularized architecture, and automated testing across the company.
Collaborate Across Boundaries: Work closely with product owners, tech leads, and other engineering teams to understand their requirements and translate them into scalable, domain-agnostic solutions.

What you will need to succeed

You have extensive industry experience as a Senior Backend Engineer developing, optimizing, and troubleshooting large-scale applications written in Go (6+ years).
You have a solid understanding of (or direct experience with) core foundational services like Identity/Authentication protocols (e.g., Keycloak, OAuth2, OIDC) and search engines.
You possess a deep understanding of data structures, algorithms, and distributed system design. You know how to build modular, high-volume services that remain performant under heavy traffic.
You have a track record of designing clean, secure, and developer-friendly internal APIs that scale across multiple engineering teams.
You are comfortable working within cloud ecosystems (GCP/AWS) from an application perspective, understanding how to leverage cloud-managed services efficiently.
You break down complex, abstract problems into elegant software solutions. You communicate effectively with technical stakeholders and love mentoring others.
Experience with PHP is a nice-to-have. We have some legacy context here, so a familiarity with PHP helps if you need to understand existing logic during modernizations or integrations - but your primary daily weapon will be Go.
You engage, inspire, and motivate the people you work with. We like to have fun while building the backbone of a platform that inspires healthy living.
