Description
Company Description 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. Job Description 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 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) Qualifications 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 Additional Information 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
Responsibilities
The engineer will own backend systems end-to-end, focusing on domain modelling and production reliability for data-intensive systems supporting complex energy-market workflows. Responsibilities also include making architectural decisions for platform scaling and collaborating with Product and Ops teams to translate real-world constraints into software.
