About Us Do you enjoy bringing structure to a growing company and taking ownership of the work that keeps everything moving?
At geoFluxus, we help companies gain real insight into their waste and material streams. Our platform collects waste data from multiple sources, verifies it, and turns it into dashboards, flow maps, charts, and actionable reports. This enables sustainability, procurement, and operations teams to make better decisions, save costs, and meet compliance requirements.
Our mission is to make circularity measurable. The word “waste” shouldn’t exist: all resources should be used for as long as possible, in the highest-value way, and as close to their source as possible. We work with leading enterprises and governments across the globe to make that a reality, backed by data.
About the role Behind every fast-growing startup, there’s a huge amount of work that keeps things running smoothly, but doesn't fit neatly into any one department: invoices that need sending, contracts that need reviewing, numbers that need modelling, and a hundred small things that need someone to simply own them.
We're looking for a Business Operations Manager to become the backbone of our day-to-day operations. You'll take ownership of our financial administration and reporting, keep our contracts and processes organized, support our projects behind the scenes, and help us present our progress to investors. As we grow, you'll increasingly take work off the founders' plates - which means the exact shape of this role will evolve, and no two weeks will look quite the same.
This role is ideal for someone who is highly organized, comfortable with numbers, and energized rather than overwhelmed by variety - someone who enjoys building order out of a fast-moving, still-forming environment.
What You’ll Do
Own invoicing and revenue operations, keeping billing accurate, timely, and well-documented
Manage contracts - both client-facing and internal - ensuring they're organized, up to date, and easy to track
Build and maintain financial models to support forecasting and decision-making
Coordinate recurring administrative processes and improve how they are organised
Support project delivery beyond the content itself: tracking deadlines, following up on deliverables, and keeping project communications and reporting on track
Prepare investor metrics and reporting materials
Help organize company initiatives, from team offsites to events
Take on the wide range of one-off tasks that come with being an early-stage company - mostly administrative and organizational work that doesn't yet have a natural home, but is essential to keeping the company running
What We’re Looking For Must-have – proven track record
Strong organizational skills and a structured, detail-oriented way of working
Comfort working with financial data, contracts, and administrative processes
Ability to manage multiple, varied responsibilities and shifting priorities without losing track of details
Ability to work independently and take ownership in a fast-moving, still-forming environment
At least B2 level of spoken Dutch
Nice-to-have
Previous experience in financial modeling or investor reporting
Previous experience in contract management or revenue operations
Experience working in small, fast-growing companies
Experience organizing events, offsites, or other team initiatives
Experience supporting grant-funded, research, or client projects
The Hiring Process
First interview with company founders
Second interview including case study assignment
Team-fit interview
