(€50K base + up to €40K performance bonus | ESOP | Remote-first / Hybrid | Europe travel)
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. No dashboards nobody uses. Real tools that change how work gets done.
We’re hiring a Sales Leader to own revenue and build the sales engine that scales.
THE CHALLENGE:
The tech works. The clients trust it. Veolia, PreZero, Valoriza, and FCC are already using Humara.
Now comes the hard part: selling transformation to a traditional industry. You’ll be talking to operators who’ve run on spreadsheets for decades and asking them to trust simulations and change workflows. That’s exactly where the opportunity is.
RESPONSABILITIES:
Build the sales function
Recruit, train, and lead a high-performing team (starting with 3+ commercial profiles)
Create the sales process, tools, and rituals that scale
Own revenue growth
Hit and exceed revenue targets quarter over quarter
Build pipeline via outbound, events, partnerships, and creative channels
Close complex, technical deals with 6–12 month sales cycles
Sell transformation (not “software”)
Go deep on customer pain: inefficiency, regulation, rising costs
Translate technical capabilities into business outcomes
Present at trade shows, conferences, and client sites across Europe
Handle skeptical buyers with data + empathy
Connect Sales to Product
Run a tight feedback loop with Product + Customer Success
Help shape the roadmap based on what wins deals and keeps clients
Experiment fast
Test, iterate, learn, without waiting for permission
Bring fresh ideas and move quickly
WHAT WE'RE LOOKING FOR:
Must-haves
8+ years in B2B sales (ideally technical products/services)
Waste/recycling/environmental infrastructure experience — you know how decisions get made
Proven track record closing complex deals with multiple stakeholders
Leadership experience (built or managed teams)
Fluent English + Spanish (more languages = plus)
Strong technical selling: simplify complexity, tie features to outcomes
Nice-to-haves
SaaS / industrial software experience
Apollo, Pipedrive, LinkedIn Sales Navigator (and AI-powered workflows)
Network across waste management, engineering firms, operators
You’ll crush it if you are…
High EQ: you build trust fast and navigate complex orgs
Self-starting: you create momentum, not excuses
Comfortable in ambiguity: you write the playbook while executing it
BENEFITS OF WORKING AT HUMARA:
Impact: help shape how the world handles waste — at massive scale
Ownership: you’re not executing someone else’s strategy; you’re building it with us
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: €50K base (depending on experience) + up to €40K performance bonus
Equity: ESOP participation
Time off: 23 days vacation + public holidays
Development: training budget + support for conferences/courses
Flexibility: mainly remote with periodic in-person collaboration
