People & Office Manager

Seaborough is a nanoscience scale-up company unlocking the potential of luminescent nanomaterials. We turn bold ideas into breakthrough applications through R&D, commercialization, and licensing of nano-engineered lighting solutions. 

Our mission is to harness the untapped potential of nanoscience to redefine luminescence, asking questions others haven’t asked yet and turning bold ideas into breakthrough technologies. Together with our customers and partners, we create truly revolutionary products that improve people’s lives and contribute to a healthier planet.

Our strength lies in the people behind the science: physicists, chemists, engineers, commercial specialists, and more. All united by our shared values of ambition, innovation, and collaboration. With our combined and strong expertise in chemistry, physics, and the optical behavior of nanoscale phosphor materials, our team finely engineers material performance at the smallest scale to solve the biggest challenges. From seasoned experts to fresh, curious minds, we bring a unique mix of experience, perspectives and ‘what if’ questions that fuel breakthrough innovations. We believe the greatest impact comes from cross-disciplinary collaborations. We offer a creative and supportive work environment where your ideas are valued, and your contributions can make a real impact. 

Seaborough is located in Amsterdam, The Netherlands, a city recognized to be one of Europe’s hotspots when it comes to a fruitful start-up business environment. Seaborough is backed by the Dutch private equity firm Momentum Capital, which focuses on clean-tech companies that have the potential to challenge the existing and set the new standard in their respective areas of business.

As People & Office Manager, you’ll be responsible for running our office smoothly and supporting our team of around 20 colleagues. This is a broad and hands-on role that combines both office operations and HR responsibilities. You will report to the CFO and work closely together to ensure everything behind the scenes is well-organized and future-proof.

There is no separate HR department, which means you’ll take care of the full HR cycle as well. This includes onboarding and offboarding, drafting contracts, supporting recruitment processes, organizing training, being a sparring partner for the management team, and helping shape our strategic HR goals. You'll also maintain our HR system, contribute to our employee handbook, and be involved in our annual HR cycle.

Roughly 50% of your time will be spent on office management and 50% on HR-related work. The basics of HR are in place, and there’s plenty of room for improvement and input.
