About Spritju

Spritju is building the future of energy traceability. Our SaaS platform helps businesses track, verify, and report their renewable energy use — supporting real-time climate action, sustainability reporting, and regulatory compliance.

By simplifying how companies verify their energy sources (through streamlined energy certificate procurement) and report their usage, we bring transparency to energy consumption. As regulations increasingly require more granular verification, we’re working toward a visionary goal: building a platform that matches every kilowatt-hour of consumed energy with its generation source in real time. This is the core project we want your help with.

We envision a future where every organization stands behind its sustainability claims — creating space for real impact, incentivizing renewable energy production, and enabling genuine climate transition, hour by hour.

We’re a fast-moving, mission-driven startup. Join us as we work toward a world where clean, traceable energy is the standard.

The Role

We're looking for someone who’s ready to take the lead and grow into a long-term partner, someone who’s excited to build ownership and shape the future of our company. This CTO role is equity-based (we're not yet offering salaries), but it comes with the opportunity to join the founding team, own your work, and grow alongside what you’re building.

We understand you might have another job for financial stability. This role and our company isn’t a regular 9-5, we’re looking for people who build for themselves, and who are responsible and driven by the success of what we’re creating.

What matters most is that you’re motivated to prioritize the success of Spritju and excited to build something meaningful from the ground up. You’ll be a key part of our founding team, with the freedom to shape the product and eventually build your own team.

Our platform helps companies trace, verify, and report their renewable energy use. We already have a working MVP (https://app.spritju.com/), and we’re now focused on improving how it works and feels for users. That’s where you come in.

​​What You’ll Work On

💡 Real-world feature development 📈 User behavior and UX optimization ⚙️ Automating energy data imports (from sensors or APIs) 🧩 24/7 traceability visualizations and dashboards

Project examples:

  • Refactor navigation, layout and title structure to improve clarity, usability and performance

  • Improve the UX and design of our dashboards and marketplace

  • Design cleaner, more intuitive interfaces for dashboards and energy data

  • Improve how buyers and sellers interact in our marketplace (e.g. simplify order flows)

  • Set up automated or simplified data updates (e.g. for market prices)

  • Build smart, automated API connections (e.g. connect directly to clients’ energy meters)

  • Streamline account management and user permissions

It’s a hands-on role that would be ideal for someone who wants to get involved, shape a growing climate-tech product, and make a real impact in the clean energy space. You won’t be starting from scratch, we have a working MVP and live user feedback. We’re now focused on improving usability, trust, and speed as we scale.

If you’re someone who gets things done, enjoys solving practical problems, and wants to build for the future, we’d love to talk.

Working at
Spritju

As the world pushes to limit global warming, energy remains one of the hardest industries to trace, even though it accounts for 73% of global carbon emissions. Traditional tracking systems rely on basic, annual certificates that lack the detail and transparency needed to drive meaningful change. Companies spend over €24.4 billion annually on these outdated certificates, facing high costs and uncertainty—obstacles that slow down progress toward carbon neutrality. At Spritju, we're changing that. Our B2B marketplace for energy certificates empowers companies to cut costs by 20% and track their energy use with precision, offering certificates with 8,760 times the granularity. By joining Spritju, you’ll play a hands-on role in shaping a more transparent, sustainable energy landscape. Your work will contribute to a future where companies can confidently reduce their carbon footprint, moving us all closer to a sustainable and accountable energy future.
