With offices across Europe and the US, we are shaping the future of scalable and secure business technology.

Why this role matters
As we scale our platform and product landscape, the need for shared foundations, consistent architecture, and efficient developer workflows becomes critical. This role ensures that teams are not solving the same problems repeatedly, but instead build on well-designed, reusable solutions. You will play a key role in connecting teams, identifying common patterns, and turning them into scalable platform capabilities. Your work directly impacts engineering velocity, system quality, and long-term maintainability across the organization and beyond.

This position follows a hybrid work model with a requirement to be in the office three times per week.

• Define and evolve best practices, architectural guidelines, and development standards
• Translate product needs into generalized, reusable solutions
• Improve developer experience, tooling, and engineering workflows
• Support teams in solving complex technical issues and removing bottlenecks
• Align architectural decisions across services, systems, and technologies
• Acting as the "voice of the developer" internally, feeding feedback from the community back to the platform engineering teams to shape the roadmap

Your Experience

• Extensive experience building and operating enterprise cloud systems
• Strong cross-stack knowledge, including
  • TypeScript and modern React-based frontend ecosystems
  • JavaScript/TypeScript backend development
  • APIs and distributed systems design
  • Optional: Experience in distributed systems development
• Proven track record of creating reusable abstractions and shared components
• Experience defining and driving engineering standards and best practices
• Strong writing and public speaking skills for presentations, workshops, and documentation
• Ability to balance short-term pragmatism with long-term architecture
• Interest in improving developer productivity and engineering quality

What Success Looks Like

• Teams adopt and rely on shared libraries and platform components
• Clear and consistent engineering standards are established and followed
• Reduced duplication of effort across teams through reusable solutions
• Improved developer experience and faster adaption rates
• Architectural decisions are aligned and scalable across products
