As a pioneer in the energy transition, Eneco aims to be climate neutral by 2035 — not only as a company but together with all our customers. This ambitious target demands smart, scalable, and data-driven solutions. Our IoT platform plays a critical role in unlocking real-time data from energy assets, accelerating this transition. Want to see how data and IoT drive our strategy? Read more in “Data en IoT zijn onmisbaar voor een succesvolle energietransitie”.
As a Senior Software Engineer, you’ll play a key role in the ongoing development of our steering box—an IoT device used to steer and connect decentralized energy assets across the grid. These assets include solar farms, wind turbines, batteries, and industrial boilers. The platform is mission critical and must be flexible, robust and scalable as we grow.
You’ll work on developing new features, improving simulation environments, test coverage, observability, and deployment pipelines. You’ll also help mentor colleagues, shape engineering practices, and take part in a rotating on‑call schedule to support live operations when needed.
- Write clean, well‑documented, and testable Python code
- Translate complex feature requests into scalable and reliable solutions
- Design and implement improvements to testing, monitoring, and deployment processes
- Share knowledge, give feedback, and support peer development through mentoring
- At least 4 years of demonstrable experience writing production‑ready Python code, preferably shared via a personal GitHub/portfolio or through a technical assignment
- Experience with Docker, CI/CD, and cloud/edge deployments (we use Azure DevOps and Azure IoT Edge)
- Basic knowledge of networking concepts (routing, firewalls, protocols), minimum at Networking Essentials level
- Strong grasp of testing strategies, debugging approaches, and design principles
- Experience mentoring peers and contributing to architecture or system design
- Strong collaboration and communication skills — you bring ideas and can convince others to follow your lead, not just code
- A proactive mindset, with a focus on reliability, scalability, and continuous improvement
You’ll be part of an enthusiastic and motivated team within the Tech department Assets. The team consists of around 30 colleagues divided into Edge/Network, IoT Platform, and SCADA (OT) sub‑teams. You’ll collaborate closely with your direct teammates, business stakeholders, and external partners to realize Eneco’s strategy and ensure we remain at the forefront of the energy transition.
If this role sparks your interest and you’re excited to join Eneco, we’d love to hear from you.
- Develop reliable and maintainable software for Eneco’s IoT edge devices that steer over 1GW of energy assets
- Lead improvements in the testability, monitoring, and scalability of our Python‑based platform using Azure IoT Edge and Docker
- Take ownership of complex features, support mentoring, and help grow a mature, resilient product
