Senior Java Developer @ Flux.host

📍 Location: Rotterdam
🎓 Level: Bachelor/Master
💰 Salary: Competitive + Equity

Software development is slow and complex.

Over the past decades, software development has evolved significantly. But with every new technology came more tools, more layers, and more complexity—creating a chain reaction of inefficiencies:

🚧 Too many tools – From databases to API gateways, DevOps tools, monitoring services, and CI/CD pipelines. Every extra tool adds more configuration, more maintenance, and more integration problems.

⚙️ Too much overhead – Engineers spend a massive amount of time on infrastructure management, debugging, and technical overhead instead of building actual features.

📝 Too much code – Most applications are 90% boilerplate and infrastructure code—making them bloated, error-prone, and difficult to maintain.

📉 Limited resources – Startups and scale-ups don’t have the time or budget to build entire DevOps, Cloud, or Infrastructure engineering teams. As a result, many ideas never come to life.

Flux is here to change that.

Flux Capacitor is a Software Engine that makes development 100x faster and codebases 90% smaller. Once built, applications are deployed with a single line of code to Flux Cloud.

What makes Flux unique?

🔥 Flux Capacitor
Think of a Game Engine—but for business software. Most of the technical complexity around scalability, messaging, auditing, security, and more is already solved. Developers can focus 100% on business logic.

☁️ Flux Cloud
A fully managed cloud provider where everything you need is already running. No DevOps, no cloud engineers, no third-party SaaS tools—just build, deploy, and you’re done.

From development to production, Flux eliminates traditional IT infrastructure.
No AWS. No databases. No custom monitoring stacks. Just pure innovation and feature development.

Your role

As part of our exclusive core team, you will work on Flux itself. This is not just another Java developer role. You will:

• Design and build our revolutionary Engine and Cloud Platform

• Work with Java, Angular, and Kubernetes, directly alongside our founders

• Radically simplify software development for developers worldwide

Who we’re looking for – Only the best

We hire only the top 1%. This is not a place for mediocrity. If you join us, it means:

• You think faster and sharper than the rest. Where others get stuck, you see patterns and solutions.

• You solve problems at the root. No bandaids—only deep, permanent fixes.

• You see what’s wrong with the world—and have the skills to fix it.

• You understand modern architectures. Event-sourcing, CQRS, hexagonal architectures.

• You want to build something that transforms the industry. Not just minor improvements.

What we offer (and what we don’t)

✅ A small team of A-players. Work alongside the very best.
✅ A competitive salary + travel expenses. Obviously.
✅ Equity. Be part of something big and share in its success.
✅ 25 vacation days. As long as you promise to come back. 😉

❌ Not a standard job. You work here because you want to build something groundbreaking.
