Founding Full Stack Engineer (m/f/d)

About the Job

We’re looking for a motivated Founding Full Stack Engineer (m/f/d) to join one of our A11 ecosystem companies in Munich, an innovative B2B SaaS solution focused on optimising energy purchasing for industrial companies, and build its energy procurement platform.

In your day-to-day work, you’ll focus on developing scalable backend services, designing intuitive user interfaces, and translating market data and customer needs into enterprise-grade solutions. You’ll work side by side with the founding team to shape the technical backbone of the product and get the opportunity to contribute to various projects.

In this role, you’ll:

• Design and develop performant backend services for a data-intensive application
• Build intuitive and elegant user interfaces for real-time market insights and simulations
• Translate customer needs and feedback into solutions, fast
• Take ownership of the full development lifecycle — from design to deployment
• Shape the tech stack, which, like the product, is still in its early stages. You’ll help define the tools and technologies the company will rely on for years to come. While React and TypeScript are currently in use, what matters most is an open, technology-agnostic mindset and strong fundamental engineering know-how, rather than syntax knowledge of a single framework.

Your Profile: 

• Proficiency in modern development stacks
• A product-focused mindset and an eye for clean, maintainable code
• Curiosity for energy markets, trading systems, and complex business applications
• Ability to thrive in an early-stage, fast-paced startup environment
• Fluent in English; knowledge of German is a plus
• Located in or willingness to relocate to Munich for full-time involvement

Please note that this position is based in Munich. 

Benefits and Perks:

• Work side by side with experienced and ambitious co-founders who bring a clear vision and a strong network
• Full autonomy in technical decisions, from selecting the tech stack to scaling the product
• Take on diverse challenges that drive both technical and personal growth
• Take ownership of a critical area from day one and see the direct impact of your work
• The industrial energy procurement market is ripe for disruption; their early traction confirms the demand and market potential
• You’ll shape the company’s vision and technology from the ground up
• Your upside scales with the company’s success

If you’re eager to join the A11 Ecosystem and shape what’s next, we want to hear from you!
