Principal Engineer - Merchant Growth Tribe

Berlin · Engineering

The Merchant Growth Tribe’s mission is to build an ecosystem of simple yet powerful products for our 1.5m+ merchants around the world which will help them grow their business. In addition to our core product, the Point-of-Sale (POS) application, the teams within the Tribe also provide merchants with invoicing and eCommerce solutions.

Beyond this, we aim to expand SumUp’s ecosystem with additional products and services such as accounting, marketing, loyalty and business analytics, all available in one place. The products we develop strengthen SumUp’s value proposition and ability to serve small merchants around the world.

As a Principal Engineer, you’ll work along-side other Principal Engineers and engineering leaders building a common platform, tools and elements where needed to support a multi-product ecosystem.

What you will do:

  • Advise teams on engineering and architectural challenges. Your engineering experience will help you advise teams on potential pitfalls, whether scalability, maintenance or divergence from the general engineering strategy.

  • Be a tie-breaker between competing solutions or teams. By delving deep into proposals and understanding context, you’ll help teams pick from competing solutions of similar merit.  

  • Be a driver/sponsor of cross-squad or cross-tribe concerns, identifying common problems and leading the implementation of solutions and  infrastructure.

You’ll be great for this role if

  • You understand the importance of cross-functional team spirit vs. traditional expert-based organisations.

  • You have a strong Computer Science foundation (with or without a formal degree) and experience in designing and building large enterprise software systems (distributed system is a plus).
