Senior Java Backend Engineer Hoofddorp

Your job:  Senior Java Backend Engineer Hoofddorp

• Do you want to help build a scalable platform that enables healthier choices for millions of people worldwide?
• Do you enjoy solving real-time backend challenges where thousands of devices send data 24/7 and reliability is everything?
• Would you like to join a profitable scale-up where you can still pioneer, shape standards and grow with the company, while also joining through stock options?
• Do you say yes to working at an amazing office for 3 days per week with highly motivated colleagues, really making the brand new platform your baby, see it scale all over the world and earn up to 90K+stock options?

The Organisation: Scale-up combining hardware and software for global impact

This fast-growing scale-up is on a mission to bring health and quality into a market that has been dominated by junk for decades. They combine innovative hardware with a scalable software platform, making it possible to distribute fresh and healthy options reliably and at scale.

The business is already profitable and cash-positive, yet still at the beginning of its growth curve. With customers across Europe and beyond, adoption is only accelerating: one client alone might soon run thousands of connected devices, all sending real-time data that must be processed securely, reliably and 24/7.And this will be millions in the future, all over the world!

In their modern office you’ll literally see the product standing in front of you: hardware and software working together. It’s a highly tangible environment where your code instantly comes to life. The culture is international, English-speaking, close-knit and collaborative: three days a week in-office, two days remote.

The Role: Senior Java Backend Engineer Hoofddorp – pioneer the platform and make it

As Senior Java Backend Engineer Hoofddorp you’ll join at a stage where much is still to be defined. The backend is being built with Java 21 and Micronaut in a modern, containerised cloud setup, and you’ll get the chance to co-create the standards, architecture and roadmap.

You get to design and build from scratch their platform that customers will use as their single control center: to monitor devices, configure products, manage prices, run promotions, control lighting and ensure everything operates smoothly 24/7. Your work will directly shape how clients interact with and rely on the system worldwide.

Your challenges will include:

• Designing event-driven services to process continuous real-time data streams from thousands (and future millions) of connected devices worldwide.
• Building APIs that empower customers to control, monitor and configure their devices and product portfolio.
• Creating a system that is scalable, secure and fault-tolerant, supporting 24/7 availability.
• Migrating and consolidating functionality from acquired systems into one unified global platform.
• Helping shape the engineering culture: coding standards, DevOps practices, and even deciding which technologies and conferences the team should invest in.

This is a chance to make the platform your own: you can grow with the product for years to come, and in the future potentially build and lead your own team.

Requirements

• 5+ years of professional backend experience with Java.
• Strong with Java 11+ (ideally 17/21) and modern frameworks (Micronaut, Spring Boot).
• Solid communicator, you enjoy working closely with business
• Proven experience with event-driven architectures, messaging, API-first design.
• Solid knowledge of cloud environments (private or public), Docker, CI/CD, monitoring.
• Pragmatic engineer who values clean code, testing, reliability and scalability.
• Comfortable in a fast-moving scale-up environment.
• An EU passport: unfortunately they are not able to sponsor visa’s for non-EU nationals
• Bonus: IoT, distributed systems, or mentoring experience.

What’s Offered

• Salary between €70.000 and 90.000 depending on experience and impact.
• Stock options to share in the company’s growth.
• Hybrid setup: 3 days/week in-office, 2 remote.
• 25 vacation days + travel allowance.
• The best MacBook
• Training budget & conference attendance.
• Parking at the office, good public transport connection.
• A highly tangible product: hardware + software combined, your code in action every day.
• A profitable, growing company where you can pioneer now and grow later, with the chance to shape your own role and team.
