Senior Software Developer (gn)

Your mission

The Bikeleasing Group is one of Germany’s leading providers of employer benefits and mobility solutions. With several specialized companies, strong profitable growth and a clear product vision, we are in the midst of a major technical transformation: modernizing legacy systems, building domain-oriented services and strengthening our engineering organization for long-term scalability. As a Senior Software Developer (gn), you play a key role in this journey. You don’t just deliver features - you actively help reduce technical bottlenecks, modernize existing systems and significantly increase your team’s delivery capability. What makes this role special: real impact, technical ownership, remote-first work, and the opportunity to drive delivery and modernization in parallel - hands-on, within a team. Sounds like your next step? We’re looking forward to your application.

• You design and implement business capabilities in modern backend and frontend services, with a backend-leaning focus
• Where required for delivery, stability or safe migration, you actively contribute to changes in legacy systems
• You translate business requirements into clean technical specifications, meaningful solution designs and robust implementations
• You identify and improve technical bottlenecks, unnecessary coupling and structural delivery obstacles
• Existing systems are continuously improved by you through refactoring, decoupling and pragmatic modernization during live operation
• You collaborate closely with Product Owners, Tech Leads and Engineers to clarify business rules and technical dependencies
• Junior engineers are supported by you through code reviews, technical sparring and living best engineering practices

Your profile

• You bring 5+ years of experience as a Software Engineer
• You have strong skills in modern backend technologies such as Kotlin, TypeScript, Spring Boot or comparable stacks
• You are comfortable working in heterogeneous environments, including legacy systems
• You turn unclear requirements and implicit business logic into solid technical solutions
• APIs, integration patterns, data models and operational implications of technical decisions are familiar to you
• You value high engineering standards: testability, code quality, maintainability and production awareness
• You confidently use AI tools as productivity enablers without compromising quality or accountability

Why us?

• You are part of a growing organization where you can actively shape things and build a strong long-term career
• Office-centric work? Not for us. We offer maximum flexibility with a remote-first setup, flexible working hours and a workation policy
• Modern tech stack (incl. Kotlin, TypeScript, PHP, Python; Spring Boot, Vue.js, React, NestJS, Symfony; AWS & Terraform)
• High-quality technical equipment with free choice of operating system (Windows or macOS)
• We value real sparring: open communication, honest feedback and collaboration at eye level
• Via Probonio, you receive a €50 monthly voucher of your choice - plus €60 annually for your birthday
• In addition to attractive company pension benefits, you receive capital-forming benefits
• And of course, you can lease up to two bicycles or e-bikes through us as your employer
