Job Description


Principal Go Backend Developer | Utrecht, Netherlands


On-site, 5 days per week (office-first environment)


Balanz Energy is building software for one of the biggest challenges in the Dutch energy market.


As renewable energy production continues to grow, the grid becomes increasingly difficult to balance. Balanz Energy helps renewable energy providers and solar field operators optimize their assets in real-time through forecasting, automated trading logic, and asset-level optimization.


The role

You will work on backend systems that process real-time market data, weather forecasting data, asset information, and trading logic. The work combines distributed systems, event-driven architecture, automation, and large-scale data processing.


As a Principal Go Backend Developer, you will take ownership of key backend systems and play a leading role in architectural and technical decisions. You will help shape how the engineering team builds, scales, and evolves its systems while remaining hands-on with implementation.


You will work closely with engineering and business stakeholders to translate complex requirements into pragmatic, reliable technical solutions. You will help shape engineering practices as the team grows.


About Balanz Energy

Balanz Energy recently went live in the Dutch market and is growing rapidly. The company combines software engineering, forecasting and trading logic to help renewable energy assets perform more efficiently and profitably.


The engineering team is intentionally small and highly product-focused. By the end of the year, the engineering team will likely consist of around five engineers.


AI-assisted coding is fully embedded into the engineering workflow. The team actively uses coding agents and AI tooling to move at a speed normally associated with much larger engineering organizations.

Requirements

  • 10+ years of backend engineering experience
  • Strong professional experience with Golang
  • Strong understanding of concurrency and asynchronous processing
  • Proven experience designing and building scalable backend systems
  • Experience making architectural and technical decisions for production systems
  • Ability to take ownership of complex technical areas from design through implementation and operation
  • Comfortable working hands-on while providing technical direction to other engineers
