This is Adyen

Adyen provides payments, data, and financial products in a single solution for customers like Meta, Uber, H&M, and Microsoft - making us the financial technology platform of choice. At Adyen, everything we do is engineered for ambition. 

For our teams, we create an environment with opportunities for our people to succeed, backed by the culture and support to ensure they are enabled to truly own their careers. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster.

Authentication Interfaces

The Authentication Interfaces team delivers a range of authentication products that provide an additional layer of verification for on-line payments.  We own a multitude of authentication mechanisms leveraging a wider range of data and biometrics to deliver an improved, consistent online shopping experience.

Authentication ensures seamless journeys, minimizing friction while securing transactions. We enable our merchants to minimize fraud and increase conversion and authorization rates by adding an additional layer of security to confirm a shopper's identity. We help merchants grow their business with improved authorization rates, lower fraud, liability protection, and compliance with local industry regulations.

We maintain services of critical importance, processing more than 130 million transactions in an average week at Adyen.  Processing at scale is business as usual for us.

Our crucial role extends beyond existing methods for securing payments: we are heavily investing in and developing cutting-edge technology, including passkeys for authentication and solutions for agentic commerce. This commitment helps our merchants stay competitive in the continually evolving payment and tech environment.

What You'll Do

As an engineer on our team, you'll have full ownership of the features you build, from initial design to deployment and live monitoring. You'll be a problem-solver shaping a core part of Adyen's platform.

  • Design and build solutions for highly scalable and reliable distributed systems that are central to Adyen's success.
  • Collaborate closely with your team, product managers, and other engineering teams across the Uplift and Payments domains to refine and implement your ideas.
  • Take end-to-end ownership, seeing your work through the entire development lifecycle.
  • Uphold our high standards for system health by implementing robust monitoring, defining SLOs, and creating effective alerting.
  • You will be part of a diverse and inclusive team. 
  • We launch fast and iterate often. Concretely, this means that within your first few weeks, you will bring code live that impacts many businesses and shoppers.
  • Collaborate across teams and time zones to make things happen, review code, and be open to giving and receiving feedback.

Who You Are

We're looking for a colleague who is passionate about building robust, large-scale systems and understands the importance of reliability.

  • You have a strong foundation in Java, with experience building web services, REST APIs, and working with streaming data.
  • You are comfortable with SQL/PostgreSQL and understand how to work with databases effectively.

Our Diversity, Equity and Inclusion commitments 

Our unique approach is a product of our diverse perspectives. This diversity of backgrounds and cultures is essential in helping us maintain our momentum. Our business and technical challenges are unique, and we need as many different voices as possible to join us in solving them - voices like yours. No matter who you are or where you’re from, we welcome you to be your true self at Adyen. 

Studies show that women and members of underrepresented communities apply for jobs only if they meet 100% of the qualifications. Does this sound like you? If so, Adyen encourages you to reconsider and apply. We look forward to your application!

What’s next?

Ensuring a smooth and enjoyable candidate experience is critical for us. We aim to get back to you regarding your application within 5 business days. Our interview process tends to take about 4 weeks to complete, but may fluctuate depending on the role. Learn more about our hiring process here. Don’t be afraid to let us know if you need more flexibility.

This role is based out of our Amsterdam office. We are an office-first company and value in-person collaboration; we do not offer remote-only roles.

What you need to know about the Melbourne Tech Scene

Home to 650 biotech companies, 10 major research institutes and nine universities, Melbourne is among one of the top cities for biotech. In fact, some of the greatest medical advancements were conceptualized and developed here, including Symex Lab's "lab-on-a-chip" solution that monitors hormones to predict ovulation for conception, and Denteric's vaccine for periodontal gum disease. Yet, the thousands of people working in the city's healthtech sector are just getting started, to say nothing of the tech advancements across all other sectors.
