As a Database Engineer in our Retail department, you'll be instrumental in optimizing the core data infrastructure that powers these experiences for millions of users, directly contributing to our mission of reinventing banking. Join our team at Backbase, one of the LinkedIn Top Companies of 2023 in the Netherlands, known for our great work environment and opportunities for career growth. We're committed to fostering a culture of collaboration, innovation, and growth, where you'll work with some of the brightest and most talented people in the industry to help shape the future of digital banking.

The job in short: Are you a performance enthusiast with a deep understanding of databases, ready to be the ultimate database authority within Backbase? As a Database Engineer (also known as a Performance Engineer or DBA), you'll diagnose and resolve complex database performance issues, ensuring our digital banking platform operates at peak efficiency for our global customers.

What you'll do

• Database performance engineers are a cornerstone of Backbase technology. You'll provide invaluable guidance to our development teams (tribes and squads) in their approach to databases and data design, ensuring our microservices deliver optimum performance. You'll analyze and interpret large volumes of performance data to characterize application behavior while proactively scanning for potential problems. Once an issue or bottleneck is identified, you'll build simulations to test your findings, and upon confirmation, you'll clearly explain it to Technical Architects and guide them towards a solution. We believe in having the guts to push limits and break barriers to make things happen, continuously learning and reinventing ourselves for maximum impact, never giving up. Your duties will include:
• Explaining complex findings to a variety of technical audiences.
• Testing our Proof-of-Concept (PoC) products to ensure they achieve our ambitious goals.
• Ensuring overall software quality, scalability, and performance.
• Working closely with our cloud solutions team on their Minimum Viable Product (MVP) and launch.
• Acting as a consultant to our internal development teams and educating them on performance.
