Technical Co-founder

Are you a builder who wants your code to matter? At Bloss lab, we're on a mission to make sustainability management effortless and intelligent. We're building a platform that helps corporates and financial institutions measure, manage, and act on their sustainability performance to turn complexity into clarity. We have traction, a clear vision and a growing customer base. Now we're looking for a technical co-founder to join us and own the product from the ground up. What you'll do

Co-architect and build further on our core platform, from data pipelines to user-facing product Own all things tech: infrastructure, stack decisions, engineering culture Work hand-in-hand with the founding team to translate sustainability challenges into elegant software solutions Help us move fast without breaking things (or the planet) Attract and eventually lead a world-class engineering team

What we're looking for

Strong full-stack engineering background (we're stack-agnostic, but you should have strong opinions) Experience building and scaling SaaS products Comfort with data-heavy applications, APIs, and cloud infrastructure A genuine interest in sustainability (you don't need a PhD in ESG, but you do need to care) Entrepreneurial mindset: you thrive in ambiguity, move fast, and take ownership Bonus: experience with AI/ML integrations and/or working in climate/sustainability tech

What you get

Co-founder title and meaningful equity (this is your company too) The chance to build something from the ground up with real impact Flexibility on location (we are in NL and Belgium and are remote-friendly, but nothing beats meeting in RL at least every other week) The ability to start part-time, we care about finding the right person, not the perfect schedule from day one
