Help us to push the Circular Economy.
If you want to be part of a company committed to the environment and efficient waste management, and contribute to a large-scale circular economy, this is the place for you.
Product Lead
CONTENT:
Everyone's talking about terraforming Mars. Meanwhile, waste infrastructure is still being designed with Excel from the '90s. Plants built with those tools will run for 25 years.
We're Humara. We build physics-based simulation software that helps engineers and operators design better plants faster, and run them smarter. Veolia, PreZero, Valoriza, and FCC are already using it.
We're hiring a Product Lead to own the space between Sales, Development, and the client, the person who makes sure what gets sold is what actually gets delivered, on time and correctly scoped.
THE CHALLENGE:
A deal closes. Now someone has to turn it into a real implementation: define scope precisely, keep Sales, Development, and the client aligned, and drive the project to a working, delivered outcome, without anything falling through the cracks.
Right now that "someone" doesn't fully exist. We need someone who can hold both sides of the equation: real engineering judgment about what's being asked, and real project ownership to make sure it ships.
RESPONSABILITIES:
Own project delivery end-to-end
Turn a signed deal into a clear implementation plan: scope, milestones, owners, timeline
Evaluate client requirements with engineering judgment, not just as a message-passer
Track risk and dependencies proactively, flag and unblock, don't just report
Run several client implementations in parallel without losing track of any of them
Coordinate across Sales and Development
Be the technical translation layer between what's sold, what's technically feasible, and what the client actually needs
Keep timelines realistic, and renegotiate them honestly when they're not
Represent the project to the client
Run product demos and onboarding sessions as part of driving the project forward in English, regularly
Be a trustworthy, technically credible point of contact throughout implementation
WHAT WE'RE LOOKING FOR:
Must-have
Engineering degree/background, you need real technical judgment to evaluate what a client is actually asking for
Real project/product ownership experience, you've owned technical or client-facing projects end-to-end, not just attended their meetings
Strong analytical / quantitative thinking, comfortable reasoning with numbers, not just words
Weighs heavily in our decision
Experience in waste treatment / industrial processes this matters a lot to us and will be weighted strongly in evaluation
Formal PM training (PMP, Scrum, PRINCE2) is welcome but not required
Also needed
High/fluent English, you'll be client-facing internationally on a regular basis
Fluent Spanish
Strong communicator, equally credible running a client demo and debating scope with engineers
Structured and organized, nothing slips through the cracks on your watch
You'll crush it if you are…
An engineer who thinks in milestones and dependencies, not just specs
Comfortable with numbers and technical detail, and able to translate both ways, client to engineering, engineering to client
Calm under pressure, juggling several live projects doesn't rattle you
Low-ego, high-ownership: you chase the outcome, not the credit
BENEFITS OF WORKING AT HUMARA:
Impact: help shape how the world handles waste at massive scale
Ownership: you're not executing someone else's plan; you're the one keeping the whole delivery on track
Team: small, exceptional, no politics
Growth: waste is just the start, industrial material flows are next
Flexibility: remote-first / hybrid; travel when it matters
The package
Salary: €28K–32K base (depending on experience) + performance bonus
Equity: ESOP participation
Time off: 23 days vacation + public holidays
Development: training budget + support for conferences/courses
