About Spritju
Spritju is building the future of energy traceability. Our SaaS platform helps companies track, verify, and report their renewable energy use, enabling real-time climate action, sustainability reporting, and compliance with emerging regulations.
We simplify how companies procure and match energy certificates and report their consumption transparently. Our vision: match every kilowatt-hour of consumption with its generation source, hour by hour. This is where you come in.
đ The Role
Weâre looking for a hands-on technical leader whoâs excited to shape and build a product from the ground up, not just manage a team. Youâll join Spritju as CTO / Founding Engineer, working closely with the founders to define the product architecture, build core features, and scale the platform.
This is an equity-based founding role. We know many great builders keep a day job at first, thatâs fine. What matters is that youâre driven to build ownership, take responsibility, and grow with the company.
Weâre not looking for a corporate CTO who delegates everything, we need a builder who can lead, who knows what to build and how to build it.
Youâll be joining at a critical stage: we have a live MVP https://app.spritju.com/ and user feedback. Now weâre focused on making the product faster, clearer, and scalable for global energy markets.
What Youâll Work On
You might be a senior engineer, tech lead, or product-minded CTO whoâs ready to apply your skills in a founding context.
