Senior Backend Engineer (all genders)

Your mission

Build the backbone of intelligent energy systems.
You design and operate the backend services that turn complex optimization logic into reliable, real-time decisions for industrial energy assets.

From core optimization APIs to deep integrations with energy management systems, you make sure our platform is fast, observable, and trustworthy. Your work enables customers and partners to confidently run batteries, solar, electric vehicles, and more at scale.

This role is about owning critical systems, not maintaining CRUD. You work close to the core of the product, where architectural decisions directly affect performance, resilience, and real-world impact.

Core Backend Systems: Design, build, and evolve the services that power our optimization platform. You work on core APIs, orchestration logic, and system boundaries that need to be correct, fast, and predictable.

System Integration & APIs: Own integrations with external EMS platforms, partners, and customer systems. You design clean, well-documented APIs and handle real-world constraints like partial data, retries, and failure modes.

Infrastructure & Operations: Take responsibility for how services run in production. From CI/CD and cloud infrastructure (Heroku / AWS) to monitoring, alerting, and performance tuning, you ensure systems behave well under load.

Scalability & Reliability: Design for growth. You proactively identify bottlenecks, improve observability, and harden systems so they scale across customers, sites, and time horizons without surprises.

Own Delivery End-to-End: Work onsite-first in a small, cross-functional team. You take features from concept to production, including design, implementation, testing, deployment, and monitoring.

Technical Excellency: You naturally raise the bar. You influence architecture through code, mentor peers when needed, and help shape how backend engineering is done at EnopAI.

Your profile

• 7+ years of experience building and operating production-grade backend systems.
• Deep expertise in Python, with significant hands-on experience in FastAPI, asyncio, relational databases and tools such as SQLAlchemy.
• Agentic Mindset: You strive to ship things 10x faster by orchestrating AI agents to handle boilerplate, testing, and refactoring so you can focus on high-level architecture.
• Cloud & DevOps: You are comfortable in cloud-native environments and experienced with DevOps workflows like CI/CD and infrastructure as code.
• Strong architectural intuition. You design solutions that are robust today and extensible tomorrow, and you also know when to keep things simple.
• Founding Mindset. You think like an owner, not just an executor: proactive, hands-on, and comfortable making key technical decisions.
• You enjoy working with strong engineers and holding yourself and others to high standards.
• Onsite-first. You value the speed, trust, and collaboration of working in person with a small, driven team in Munich.
• Bonus: Experience with InfluxDB or other time-series databases. Interest in energy systems or optimization algorithms.
