Senior Golang Backend Developer

Utrecht, Netherlands | Posted on 26/05/2026

The opportunity

Balanz Energy is looking for a Principal Go Backend Developer to help shape the backend architecture of a growing energy technology platform.

You will join a small engineering team building systems that support automated energy trading, renewable asset optimisation, forecasting, and market decision making. The work sits at the intersection of software engineering and the physical energy market, where system performance and decision quality have a direct commercial impact.

This is a hands on Principal role. You will remain close to the code while taking ownership of architectural decisions, technical standards, and the evolution of the platform.

About Balanz Energy

Balanz Energy is building infrastructure to help renewable energy providers operate their assets more intelligently.

As solar and wind generation continues to grow, energy production becomes increasingly dependent on weather conditions. Balanz Energy combines forecasting, market data, automated trading, and asset optimisation to help customers make better decisions in real time.

The company recently went live in the Dutch market and is building towards significant growth. This creates an opportunity to join at an early stage and have genuine influence over how the technology develops.

Engineering environment

The engineering team is intentionally small and highly autonomous, with approximately five developers expected by the end of the year.

The stack is evolving alongside the product and currently includes:

Go as the primary backend language

Python for machine learning workloads and scripting

Kubernetes for infrastructure and orchestration

PostgreSQL and ClickHouse for data storage and analytics

Redis for caching and fast data access

NATS JetStream for messaging and event driven communication

Svelte on the frontend

AI assisted development is part of the team's normal workflow, with coding agents and other AI tooling used to accelerate development and reduce repetitive work.

The expectation is that engineers use these tools intelligently while retaining ownership of design, implementation, testing, and technical decisions.

What you will do

Shape the architecture and technical direction of the backend platform

Design and develop high performance services in Go

Build systems capable of handling large volumes of market, weather, and asset data

Make decisions around scalability, reliability, performance, and maintainability

Establish strong engineering practices around testing, observability, and system reliability

Work closely with product and business stakeholders to translate requirements into practical technical solutions

Mentor other engineers and raise the technical bar across the team

Remain hands on with implementation while providing technical leadership beyond your own area of ownership

What Balanz Energy is looking for

You are an experienced backend engineer who enjoys solving complex problems and is comfortable operating with a high degree of autonomy.

10+ years of professional software engineering experience

Strong experience with Go, including concurrency and asynchronous processing

Proven track record designing and scaling distributed backend systems

Strong understanding of software architecture and engineering principles

Comfortable making pragmatic architectural trade offs

Able to communicate technical decisions clearly to both technical and non technical stakeholders

Experience providing technical guidance or mentoring to other engineers

Comfortable working in a small team where engineers have broad ownership

A product oriented mindset and an interest in understanding the business impact of technical decisions

Nice to have:

Experience in trading, fintech, energy, IoT, machine learning infrastructure, or another data intensive domain

Experience with event driven or real time systems

Experience with Kubernetes or cloud native infrastructure

Professional experience with multiple programming languages

Team and culture

The team is direct, collaborative, and technically focused. Because of the complexity of the product and the early stage of the company, engineers work closely together and are expected to communicate openly and solve problems collectively.

Small engineering team with significant autonomy

Direct access to product and business stakeholders

Strong focus on knowledge sharing and technical ownership

Opportunity to influence the product and engineering direction as the company grows
