Senior Developer

We’re looking for a Senior Developer who builds with purpose and likes to think ahead. You enjoy building sustainable solutions and you get energy from strengthening both the team and the end product. For you, freedom and responsibility go hand in hand.

Growing at Hoppinger

At Hoppinger, growth comes from continuous learning. We test, experiment and make decisions based on what works, in our products, our way of working and how we grow as people. As a Senior Developer, you actively contribute to this mindset by combining technical excellence with curiosity, coaching and a drive for continuous improvement.

About the role

As a Senior Developer, you take shared ownership of the technical quality and delivery of our client projects. You translate ideas and challenges into robust solutions, guide your team through development and take responsibility for what goes live.

Your role is a mix of hands-on development and leadership:

• Defining technical direction and architecture
• Safeguarding quality and guiding development processes
• Coaching developers in small teams (2–4 people)
• Acting as a technical sparring partner for colleagues and clients
• Contributing to presales and solution design

Together with a Digital Project Manager, our Head of Engineering, designers and strategists, you turn ideas into scalable digital products.

You don’t just deliver software.

You build it. You run it. You care about it.

You have the freedom to shape your role, stay up to date with relevant technologies and deepen your expertise in the direction you choose, with our support.

About you

You’re comfortable with responsibility and complexity. You can set priorities, connect the dots and explain technical choices clearly. You’re open to difficult conversations because they lead to better collaboration and stronger results.

You bring:

• Experience as a Senior Developer (or similar role)
• Broad experience across front-end, back-end and (Dev)Ops
• (TypeScript, Node.js, React/Angular, NestJS, Docker, PostgreSQL, REST/GraphQL)
• A strong learning mindset and a collaborative attitude

You don’t need to know everything already.

Curiosity, ownership and willingness to learn matter most to us.

What we offer

You’ll join a culture built on trust, freedom and growth, with colleagues who share your drive. And because work isn’t everything, we also offer:

• Celebration Leave: swap national holidays for days that matter to you
• Alleo: choose additional benefits that fit your lifestyle
• 100% paid partner leave
• Hybrid working: De Bilt (Utrecht) as your main office, with the flexibility to work from home or from our Rotterdam office
• Multidisciplinary teams: working with strategists, designers, developers and PMs
• Training budget: keep learning and experimenting
• Learning organization: knowledge sharing and innovation are part of everyday work
• Fully catered lunch, with our monthly Krokettenwoensdag as a highlight
• OpenUp account for mental support, both personal and work-related
