Your Job: Medior JVM Software Engineer Amsterdam

Do you want to evolve into a senior or lead engineer by learning how to influence architecture, drive delivery, and make business impact?
Do you enjoy working on long-term greenfield projects with lasting value—designed from scratch and used by millions of users?
Would you thrive in a team of technical peers who challenge and elevate each other, while being mentored by conference-level engineers?
Do you want to explore technologies like DDD, microservices, event sourcing, and generative AI—all while working remotely up to 4 days a week and earning up to €89.160?

If so, this might be the growth platform you've been looking for.

Learn from the Best, Grow into Your Best Self

This software engineering powerhouse was founded over 20 years ago to attract and nurture the best engineers in the Netherlands. It has helped hundreds of engineers become top-level performers some now leading their own tech ventures, others speaking on international stages.

You’ll work in a collective of highly skilled engineers solving complex software challenges for companies with millions of users. Together with your squad, you’ll guide clients “from A to Better” helping them modernize their stack, processes, and delivery models. Here, growth is deliberate. You’ll get one-on-one coaching, access to a €5K training budget, and the time to truly master your craft not just learn new tools, but learn how to make impact that lasts.

You’ll be part of a company where craftsmanship, mentorship, and engineering impact are deeply embedded. From the moment you join, you’ll be encouraged to speak up, own your ideas, and shape the path forward.

Your Role: Medior JVM Software Engineer Amsterdam

As a medior engineer, you’ll go beyond just contributing code. You’ll be coached on how to navigate stakeholder discussions, make lasting architectural decisions, and help shape engineering culture within your team. Whether you're improving observability, mentoring juniors, or pitching a new approach in a design session you’re already building your senior muscles.

You'll work in a polyglot stack using Java, Kotlin, Scala, TypeScript, and Go, and explore cutting-edge tech like event sourcing, generative AI, distributed systems, and cloud-native delivery. All while being part of a multidisciplinary squad where backend, frontend, cloud, and data engineers collaborate from end-to-end. Expect continuous learning, direct mentorship, and the space to grow.

Growth Path: From Medior to Senior and Beyond

This role is structured for growth. You'll be working 1-on-1 with senior engineers who are also public speakers, trainers, and technical thought leaders.
With regular coaching, bi-weekly internal sessions, and a €5.000 yearly training budget, you'll master both the technical and consultative skills needed to become a respected senior or lead engineer if that’s your path.

4+ years of professional backend software engineering experience
Proficiency in Java, Kotlin, or Scala (plus optionally TypeScript/Go)
Experience with containerization, microservices, and cloud-native architecture is a plus
Strong fundamentals in system design, testing, and clean coding is a big plus
Curious mindset, proactive communication, and ambition to grow into a senior/lead role
A technical BSc or MSc degree (or equivalent thinking level)
