Senior Java Engineer (with Relational Database Expertise)
Tricentis
Software Engineering
Prague, Czechia
Posted on Sep 27, 2025
We’re growing qTest, the platform testers use to organize their work, into a faster, more reliable, and easier-to-use SaaS product, adopting AI where it truly benefits users. It’s already trusted by over 70,000 users and handles more than 17 million API calls every day.
We are seeking a highly skilled Senior Java Engineer with strong expertise in relational database design, optimization, and performance tuning to join our engineering team. The ideal candidate will have a proven track record of building scalable, reliable, and secure enterprise applications, with a deep understanding of both backend development in Java and relational databases. You’ll play a key role in shaping how we build it: leading technical implementation, maintaining a high bar for quality, and driving backend-focused improvements. That means reworking the storage architecture, setting up a message bus, improving APIs, splitting a monolith, enhancing features in a mature product, and tightening security.
You’ll be part of a team (paired with a PM and EM) that owns a clear product area. We work in two-week sprints, deploy continuously behind feature flags, and usually focus on projects that run one to two months.
