About Us

We are a software and data platform that brings carbon intelligence to global commodity industries.

By connecting supply-chain data, regulations, and real-world emissions, we enable producers, traders, consumers, and regulators to understand and manage the true carbon intensity of their decisions. Our multi-tenant B2B SaaS platform is intelligence-first — AI and automation are built into the user experience by default. We're currently in Stealth mode, but will launch in late Q4 2025.

The role

We’re looking for a software engineer who wants to solve real business problems through clean, reliable, and scalable software. You’ll join a small, sharp, and collaborative team where engineers shape architecture, product, and delivery decisions alike. You’ll work primarily across our backend stack, but you’ll also have the opportunity to touch data and frontend systems as we evolve.

What you’ll do

• Design and build backend services that power our data and intelligence platform.
• Own features end-to-end — from understanding the business context to shipping and maintaining production code.
• Collaborate directly with product and data teams to translate complex domain logic into simple, maintainable software.
• Contribute to a high-quality codebase through reviews, clear design, and thoughtful trade-offs.
• (Optional) Explore and contribute to related areas such as data pipelines, orchestration, or frontend development.

Python · FastAPI · SQLModel / SQLAlchemy · PostgreSQL · Celery

Other technologies we use:

React · TypeScript · Dagster · Spark · Iceberg · AWS

What we’re looking for

• Strong fundamentals in Python and web backend development.
• Solid understanding of databases, async execution, and APIs.
• Curious about how technology creates business value — you think beyond “just the task.”
• Comfortable working independently, with a sense of ownership and follow-through.
• (Bonus) Experience in data-heavy systems, B2B SaaS, or tech-based consulting.
• (Nice to have) Interest in commodities industry, the energy transition or carbon markets.

Why Us

• Small, high-trust team — fast decisions, no politics, no endless planning cycles.
• Focus on building high-quality solutions that scale, not just keeping the lights on.
• A chance to shape software that matters in the global energy transition.
• Monthly team meet-ups across Europe (travel covered).

How to apply

• Send us a short note about yourself, what excites you about the role, and a link to your profile (CV, GitHub, LinkedIn, or whatever you prefer).
