Software Engineer — Renewable Asset Intelligence Platform
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
