AI Platform Engineer (f/m/d)

At Enpal, we are not just a company; we are a movement. As a leading European greentech unicorn, we are on a mission to make clean energy simple, accessible, and scalable for homeowners across the continent.

Through solar panels, heat pumps, home batteries, and EV charging, we are redefining residential energy. With Enpal Energy, we are building Europe’s leading platform to manage and orchestrate millions of distributed energy assets — laying the foundation for the largest Virtual Power Plant (VPP) in Europe.

Our vision: power Europe’s transition to a fully decentralized, intelligent, and clean energy system.

As a Senior AI Platform Engineer, you will design and build the internal AI Engine that powers all AI capabilities across Enpal Energy. This is not about wrapping APIs — it is about building the core infrastructure that makes AI reliable, scalable, and production-grade.

We are looking for a systems thinker with strong engineering fundamentals and a deep understanding of modern AI systems. You care about reliability, observability, and building platforms that enable other engineers to move fast with confidence.

• Own the design and development of the internal AI platform powering all AI features.

• Build a robust Agent Runtime to orchestrate complex AI workflows in production.

• Design scalable backend services and developer-facing APIs for AI systems.

• Build internal tooling for evaluation, observability, tracing, and debugging (latency, cost, quality, reliability).

• Define standards for AI quality, including evaluation frameworks, versioning, and reproducibility.

• Collaborate closely with product and engineering teams to enable fast, safe, and deterministic AI feature delivery.

• Own CI/CD pipelines, infrastructure as code, and production readiness of AI systems.

• Continuously improve performance, reliability, and cost efficiency.

• Contribute to architectural decisions shaping the long-term AI strategy.

• 5–7+ years of software engineering experience (mid to senior level).

• Strong background in backend systems, platform engineering, or internal developer platforms.

• Strong proficiency in TypeScript and Node.js (JavaScript ecosystem).

• Solid understanding of modern AI system design, including agentic architectures vs. chains, tool use and function calling, and orchestration patterns.

• Experience in LLM APIs (e.g. OpenAI, Anthropic, DeepSeek) and AI infrastructure.

• Experience building observability, logging, tracing, and evaluation systems.

• Strong focus on reliability, determinism, and production-grade engineering.

• Experience building APIs and integrating complex systems.

• Familiarity with CI/CD tools (GitHub Actions, Azure DevOps, or similar).

• Strong commitment to clean, testable, and scalable code.

• (Senior level) Experience mentoring engineers and driving technical decisions.

• Join Germany’s leading green unicorn and help shape the energy transition.

• Work in a diverse team of 65+ nationalities united by one mission.

• Hybrid work model: office or remote — your choice.

• Our Berlin HQ offers a fully equipped startup environment (rooftop, gym, lounges, events).

• Structured onboarding, including a welcome session with our founder.

• Regular company updates, technical deep dives, and knowledge sharing sessions.

• Strong team culture, ownership mindset, and frequent team events.

• A strong feedback culture that values continuous improvement.

At Enpal, diversity and inclusion are core values. Hiring decisions are made without discrimination of any kind.
