We’re looking for an Application Support Specialist who is not just technically sharp but also curious about how things work and why they matter to the business. Our support team sits at the crossroads of IT Operations and Software Development, acting as detectives of production issues in both client-facing and internal applications.

This is not your typical button-pushing support role — you'll deep-dive into application behavior, investigate source code, and connect the dots between technical symptoms and business impact. If you're someone who enjoys solving puzzles, automating repetitive tasks, and wants the freedom to propose and implement ideas, we’d love to hear from you.

This is what you'll do:

• Own and resolve technical incidents by investigating logs, application code, and business flows
• Prioritize issues based on business impact and collaborate with developers when deeper fixes are needed
• Use SQL and Java to explore, reproduce, and resolve application behaviors
• Act as a communication bridge between IT, Development, and Business teams
• Spot trends, detect recurring issues, and proactively prevent future incidents
• Participate in small-scale automation or optimization projects where you will have the freedom to explore new approaches

You bring us these skills:

• 1–3 years of experience
• Strong in Java and SQL
• (Nice to have) Comfortable navigating Linux environments and using command-line tools, and experience with tools like Elasticsearch, Jira, Grafana, or Spring Framework
• Curious, independent, and eager to learn how complex systems work — technically and functionally
• Proactive team player who communicates clearly and thinks critically
• Comfortable working in a fast-paced, high-stakes environment

Interested? This is what we offer you:

• Promise of a good work-life balance
• 30 days paid leave
• An enthusiastic and fun team to work with
• Personal and professional development with access to relevant courses
• Transport allowance or related benefits like a leased electric bike
• Pension plan
• A challenging job in an international and fast-growing company
• A competitive salary
• A lot of freedom executing your role and a chance to shape your own career
• The opportunity to participate in a new, enthusiastic team of likeminded professionals

To make your life easier

• You get the freedom to work flexibly. Meaning you don’t have to work in our office every day, but we like it if you do of course! It’s fun to come in and mingle with your colleagues.
• There is also fruit, good coffee, drinks & snacks, and great sandwiches for lunch every day.
• Our beautiful and modern office is located in the iconic Rembrandt tower that is conveniently next to Amstel Station.
• To make work@home comfortable we offer a €35 internet allowance, provide a company laptop and many options to make it comfortable, such as a chair, screen and headphones.
• And last but not least: the gym membership options we provide is an easy way to get into shape!
