Versatility across these areas matters more here than deep tenure in a single one + You've taken systems into production and kept them running, and can show or talk us through examples (work projects, open source, side projects) + Experience with one or more of the following is a significant advantage: Python, Azure, Docker, Kubernetes/CI-CD tooling, SQL, KQL, Linux, and front-end frameworks (e.g., React/TypeScript) + You are based in the Netherlands and are available to be in the office two to three days per week + Strong problem-solving skills and a willingness to work with complex, unfamiliar systems + A passion for creating customer value through high-quality engineering + Curiosity, ownership, craftsmanship, and the drive to keep learning + Good communication skills, able to explain trade-offs clearly to both engineers and non-technical stakeholders + A good vibe: you bring energy to the team and make collaboration genuinely enjoyable, not just effective ## Description As a Senior Backend Engineer, you'll help turn that ambition into production reality: building the services, integrations, and cloud foundation that put our optimization and forecasting capabilities to work for customers every day. Your work will directly contribute to: + Reducing and optimizing energy costs and emissions across Europe + Enabling customers to participate in future energy flexibility and trading markets + Optimizing multi-energy systems (heat, cold, electricity, storage, HVAC) + Driving the transition toward autonomous, intelligent buildings and greenhouses + Helping customers stay compliant with increasing regulatory pressure (e.g., CSRD) What You'll Do Priva Digital Services & product engineering + Design and build backend services that process data and execute optimization logic for products across Neo Heat, Neo Light, Neo Building, and Neo Smart + Contribute to user-facing Priva Digital Services features end-to-end, including front-end work where it's the fastest path to shipping value + Build and maintain APIs for internal and external integration Optimization & forecasting integration + Implement and integrate optimization and forecasting logic into scalable, production-ready systems. You bring these models into production; you don't develop new optimization theory + Work on data processing pipelines, scheduling logic, and system orchestration Cloud infrastructure & DevOps + Own and improve cloud infrastructure (Azure) that supports scalability across Energy Solutions teams + Strengthen CI/CD, monitoring, and deployment practices so systems are reliable, performant, and maintainable in real-world operation + Collaborate with product, domain experts, and other engineers across teams to deliver end-to-end solutions + Contribute to technical design decisions within your domain, and participate in the full software lifecycle: ideation * design * development * testing * deployment * monitoring What you will NOT do + This is not a research or modelling role. You implement and integrate optimization and forecasting models rather than developing new theory + You are not expected to be a dedicated front-end specialist or a dedicated DevOps specialist. The role spans these areas by design, so depth in every direction isn't the bar
