German-Speaking Senior Backend Engineer (all genders)

Company: EnopAI
Location: Munich, Bavaria, Germany
Employment Type: Full-time

Your Mission

Build the foundation for intelligent energy systems.

You will develop backend systems that transform complex optimization algorithms into robust real-time decision-making solutions for industrial energy systems.

Whether it's the core APIs of our optimization platform or integrations with energy management systems – you will ensure that our platform runs fast, stable, and reliably. With your work, you will empower our customers to intelligently manage and optimize battery storage, photovoltaic systems, charging infrastructure, and other energy installations.

With us, you won't be developing classic CRUD applications. You will work on the technological core of our product – where architectural decisions directly impact the performance, scalability, and success of our solution.

Backend System Development

You will design, develop, and improve the central services of our optimization platform. In doing so, you will work on core APIs, orchestration logic, and the interfaces between our systems – always with the goal of creating robust, performant, and easily maintainable solutions.

Responsibility for APIs and Integrations

You will integrate external Energy Management Systems (EMS), partner solutions, and customer systems. In doing so, you will develop clean, well-documented APIs and consider practical challenges – from incomplete data and retry mechanisms to the failure of individual systems.

Contribution to Infrastructure and Operations Development

You will take responsibility for ensuring that our services function reliably in production operations. From CI/CD and our cloud infrastructure (Heroku / AWS) to monitoring, alerting, and performance optimization – you will ensure the smooth operation of everything.

System Scaling

You will design systems from the outset so that they can grow with our customers. You will identify bottlenecks early, improve observability, and ensure the stability and performance of our platform even with increasing complexity.

End-to-End Feature Implementation

You will work in a small, interdisciplinary team with a strong on-site focus and will accompany features throughout the entire development process – from the initial idea through design and implementation to deployment and monitoring.

Driving Technical Quality

You will actively apply your expertise and set high technical standards. You will participate in architectural decisions, share knowledge within the team, and contribute to the continuous improvement of backend development at EnopAI.

Your Profile

• German language Minimum 7 years of experience in developing and operating production backend systems.
• Very good Python knowledge, as well as deep experience with FastAPI, asyncio, relational databases, and frameworks like SQLAlchemy.
• AI-first Mindset: You naturally use AI and AI agents in your daily development to accelerate boilerplate code, testing, or refactoring – so you have more time for architecture, product, and complex technical challenges.
• Experience with Cloud Technologies and DevOps: You are comfortable in cloud environments and familiar with topics like CI/CD, Infrastructure as Code, and the operation of modern backend systems.
• Good sense of architecture. You design solutions that work reliably today and scale tomorrow – and at the same time know when pragmatism is more important than perfection.
• Founder Mentality: You take responsibility, think entrepreneurially, and proactively make technical decisions, rather than just executing requirements.
• You enjoy working with strong engineers, giving constructive feedback, and having high standards for the quality of your own work and that of the team.
• You appreciate the dynamics of a small team and enjoy working on-site in Munich because fast decisions and close collaboration are really important to you.
• You are fluent in German and English, sufficient for negotiations.

Nice to have

• Experience with InfluxDB or other time-series databases.
• Interest in energy systems, optimization algorithms, or mathematical models.

Why Us?

• The dynamic of an ambitious startup where your ideas matter and you have a real impact on the product and technology.
• Attractive salary, as well as additional benefits such as EGYM Wellpass.
• The opportunity to make a concrete contribution to the energy transition with your work.
• Centrally located office directly at Goetheplatz in Munich – with the option to work from home by arrangement.
• An environment in which you can continuously develop: Together with a strong team of engineers, you will build innovative software, solve complex technical challenges, and actively shape the future of intelligent energy systems.
