Software Engineer — Renewable Asset Intelligence Platform

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.

What you’ll do

• Design and develop backend features end-to-end, from domain modelling to production

• Build data-intensive systems that support complex energy-market workflows

• Contribute to 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

Tech stack:

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

• Backend: Python & Ruby on Rails

• Databases: PostgreSQL, MySQL, InfluxDB

• Infrastructure: AWS, Docker, Heroku

• Frontend: React (Next.js)

We are looking for impact-driven engineers who want to grow with the product.

You might be a good fit if you:

• enjoy understanding complex domains and turning them into software

• think in systems and workflows rather than isolated features

• are pragmatic and comfortable shipping imperfect first versions

• take ownership and responsibility for production systems

• want to continuously improve your skills and adapt to new tools and practices

• communicate clearly and collaborate well across teams

It’s a plus if you have experience with:

• B2B SaaS platforms

• data-intensive or workflow-heavy systems

• complex business rules or domain-driven design

• multi-country or regulation-driven products

Recruitment process:

• Initial Call with the Tech Lead

• Technical Test with the Tech Lead

• 2 calls with other members of the team (among PM/CTO/Dev/CEO)

• Final Team meeting to see the fit
