Role Description You architect the billing, invoicing, and monetization systems behind the global energy transition, one unified internal platform. By designing and running everything from invoicing and subscriptions to PSP-backed payments and reconciliation, you make sustainable energy financially solid and operationally scalable. The audit trails, templates, and integrations you build are what finance teams and customers trust as we grow across markets. As a Software Engineer at 1KOMMA5°, you will take technical ownership of key systems and features, driving architectural decisions and ensuring scalability, reliability, and performance. You’ll collaborate closely with other engineers, product managers, and stakeholders to shape our technical direction and deliver high-impact solutions. Beyond building solutions, you’ll mentor teammates, champion engineering excellence, and help evolve our development and deployment practices to the next level. - Contribute as a Full-stack engineer within a team of self-driven software developers. - Design, build, and maintain business-critical systems across the stack. - Partner with finance, operations, and product to translate complex, loosely defined billing requirements into clear, actionable technical solutions. - Own slices of the invoice lifecycle (generation, delivery, and archival), templating and localization, and reconciliation and reporting together with stakeholders. - Champion clean architecture, component reusability, and maintainable UI patterns using modern frameworks (e.g. React, Next.js, or similar). - Drive experiment-driven innovation and uphold strong engineering practices in testing, CI/CD, observability, and code quality. - Continuously improve developer experience by reducing technical debt, automating workflows, and documenting key decisions and operational processes. - Operate effectively in an asynchronous, outcome-oriented environment, managing your work autonomously and maintaining clear communication through documentation and structured updates. - Contribute to lightweight project management by defining milestones, ensuring technical feasibility, and aligning engineering work with product goals. Qualifications - Experience writing maintainable, reusable, and testable code in TypeScript, with strong skills in both frontend frameworks and backend technologies. - Strong understanding of API design, data modeling, and system integration (RESTful or GraphQL). - Proven ability to own features end-to-end, from UX and architecture to deployment and monitoring. - A pragmatic, product-focused mindset that balances technical excellence with delivering customer value for regulated or finance-adjacent flows. - Curiosity and initiative to explore new tools and methods that improve product quality and engineering efficiency. - Excellent written and spoken English (German is a plus). - Residency in Germany. Requirements - Strong skills in both frontend frameworks and backend technologies. - Understanding of API design, data modeling, and system integration. - Ability to own features end-to-end. - Product-focused mindset. - Curiosity and initiative. - Excellent communication skills in English. - Residency in Germany. Benefits - You are part of an international, dynamic, and highly motivated team of people who have proven to make things happen. - With your work, you accelerate the "energy transition" and hence have a direct impact on our climate. - Work with and learn from other super-smart colleagues. - You will enjoy direct contact with core decision-makers. - You will enjoy entering full-time in one of Europe’s most thriving scaleups. - You work remotely (Germany-wide), with offices in Hamburg, Berlin or Munich. - Create a healthy balance alongside your work and enjoy all the benefits of the EGYM Wellpass. - Benefits and discounts are yours with Futurebens. - Whether city bike or e-bike - be flexible with our job bike leasing and do something good for the environment at the same time.
