Who we are

At OpenUp, our mission is to make mental well-being accessible to everyone. Following a ‘high tech & high touch’ approach, we support companies, their employees, and their families with proactive and practical mental health services. Through our digital platform, clients can access 1:1 check-ins, online courses, articles, videos, group sessions, mindfulness practices, and a team of committed mental well-being experts. As we believe that mental and physical well-being are deeply connected, we have also added Lifestyle Experts to our offering, focusing on nutrition, exercise, and sleep. We offer a truly holistic approach that helps people take ownership of their health. We’re proud to work with forward-thinking organizations and are committed to raising the bar on accessible care.

OpenUp was ranked in the Top 3 on LinkedIn’s Top Startups list for 2023, 2024 & 2025 and is continuously growing. We are expanding our international teams and we are searching for like-minded talent. We are already serving 2000+ companies (e.g. Rituals, Deloitte, Decathlon, KPMG, and McDonalds), through which 600K+ employees have access to our product.

About the role 

Our Amsterdam HQ is where a lot of OpenUp's energy happens: daily lunches in the kitchen, regular borrels on Thursday afternoons, impromptu whiteboard sessions, and the occasional office yoga class. We're looking for a part-time (32h) Office Manager to keep that space humming and make sure everyone who works from, visits, or joins our office has a great experience.

You'll be the go-to person for everything office and culture related, from suppliers and facilities to team events and the general vibe of the place. It's a varied, hands-on role with real ownership over how the office feels and runs. At OpenUp we're actively adopting AI in how we work, and we'd love for you to bring that same mindset to the office: using AI to plan smarter, spend better, and free up time for the human side of the job. You'll be part of our People team and report to the HR Manager.

What you’ll do

• Run the day-to-day of our Amsterdam HQ: supplies, deliveries, meeting rooms, plants, coffee, and everything in between.
• Own vendor and supplier relationships (cleaning, catering, office supplies, IT equipment support, building management) and keep an eye on the office budget.
• Make sure the office is a place people actually want to come to: tidy, well-stocked, welcoming for guests, and set up for both focused work and good conversations.
• Organise the moments that make OpenUp, OpenUp: borrels, monthly themed drinks, anniversaries, the company-wide summer fest, Christmas party, smaller team celebrations, and more.
• Support onboarding logistics so new joiners feel welcome from day one, including welcome kit, and the office tour.
• Partner with the People team on office-related employee experience topics.
• Be the first point of contact for building management, health & safety, and any office-related questions from the team.

About You

• You've done this kind of work before, whether that was running an office, managing a busy front of house, or keeping a team's day-to-day moving behind the scenes, ideally in a fast-growing, international company.
• You're organised, proactive, and comfortable juggling a long to-do list without losing the plot.
• You genuinely enjoy creating a great experience for people, whether that's a thoughtful welcome for a new hire or a well-run team event.
• You're hands-on and solutions-oriented: if the dishwasher breaks or the caterer cancels last minute, you fix it instead of escalating it.
• You're excited about AI and already use it (or are keen to) in your day-to-day work. You don't need to be technical, you just need to be the kind of person who reaches for an AI tool before a 30-slot spreadsheet.
• You communicate clearly in Dutch & English (our working language). 
• You're based in Amsterdam and happy to be in the office 4 days a week.
• You care about mental well-being and are excited to contribute to our mission.

What you can expect 

Joining OpenUp means being part of a fast-growing company that's doing something meaningful. You'll work with a diverse and international team. We like to have fun together with a lot of team building activities like our weekly ‘borrels’ and after work sport classes, the yearly ski-trip and our Padel tournament. Which makes our work fun, challenging and dynamic. Apart from this, we offer: 

• €1500 annual personal development budget
• ClassPass: OpenUp contributes towards your classpass membership 
• Monthly home internet/phone contribution (50EUR)
• Daily healthy and vegetarian lunch at our office.
• Regular office yoga, meditation classes or breathing exercises
• Monthly drinks and company wide summer fest and other fun activities.
• 27.5 vacation days per year.
• Free and unlimited access for you and your family to all our products, including our psychologists.
