Software Engineer — Renewable Asset Intelligence Platform

Software Engineer — Renewable Asset Intelligence Platform

• Full-time

Streem Energy builds a SaaS platform helping energy players operate renewable assets across Europe: producers, aggregators and suppliers.

Our software sits at the intersection of renewable energy generation, European power markets, and complex operational workflows. We combine strong engineering, data/AI, and deep energy‑market expertise to turn real‑world signals and constraints into actionable decisions.

We are hiring a Software Engineer to help us build and scale Streem’s Energy Market Platform. This role is for someone who wants to understand the business, design systems, and deliver impact, not just write code.

You will work on backend systems that encode market rules, orchestrate workflows, and support decision‑making for our customers. You will have strong ownership over what you ship, from design to production.

A fast‑moving environment

The renewable energy market evolves quickly — regulatory changes, new financial mechanisms, shifting operational constraints.

Our platform must evolve just as fast.

We optimize for speed of iteration without compromising long‑term architectural integrity. That means building systems that are adaptable by design, making sound decisions under time pressure, and continuously improving what’s already in production.

What you’ll do:

Own backend systems end‑to‑end, from domain modelling to production reliability

Build data‑intensive systems that support complex energy‑market workflows

Make architectural decisions as the platform scales across European markets

Work closely with Product and Ops teams to translate real‑world constraints into software

Improve reliability, observability and operational robustness

Maintain high engineering standards through reviews, tests, refactors and pragmatic best practices

Problems you’ll solve:

Modelling complex energy‑market rules while keeping the system understandable and maintainable

Designing workflows that combine asset data, market data and customer actions

Ensuring data consistency, traceability and correctness across systems

Scaling the platform to support multiple countries with different regulations and mechanisms

Building internal tools that improve operational efficiency and reduce manual work

Making pragmatic trade‑offs between speed, robustness, flexibility and simplicity

This role is for you if:

You think in systems, not tickets

You care about both speed and correctness

You are comfortable making decisions with incomplete information

You want real ownership over production systems

You continuously raise your own standards

We care more about engineering fundamentals than specific tools, but our current stack includes:

Backend: Python & Ruby on Rails

Infrastructure: AWS, Docker, Heroku

Frontend: React (Next.js)

We’re looking for impact‑driven engineers who want to grow with the product — and raise the bar as it scales.

You might be a strong fit if you:

enjoy understanding complex domains and translating them into clear, maintainable systems

think in systems and workflows rather than isolated features

are pragmatic and comfortable shipping imperfect first versions — and iterating quickly

can balance speed with long‑term architectural integrity

take ownership of production systems and feel responsible for their reliability

make thoughtful trade‑offs under uncertainty

continuously improve your skills and adapt to new tools and practices

communicate clearly and collaborate effectively across technical and non‑technical teams

It’s a plus if you have experience with:

B2B SaaS platforms

Data‑intensive or workflow‑heavy systems

Complex business rules, domain modelling, or domain‑driven design

Multi‑country or regulation‑driven products

High‑velocity environments where requirements evolve quickly
