Principal Go Backend Developer

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.
