At Testportal, we help organizations around the world create secure, scalable, and user-friendly online assessments. Our platform supports millions of test-takers each year, and we're now working on disrupting the exams market in the post-GPT era.


We're looking for a driven and experienced Senior Fullstack Software Engineer who’s ready to shape the future of online tests. You'll join a tight-knit team where your ideas matter and your work will have a global impact. 


In this role you will be responsible for implementing the core of our new examination platform touching every layer of the technology stack.


What we're looking for:

  • Proven track record as a lead or senior engineer delivering JVM-based applications (Java / Kotlin, Spring) to production

  • 4+ years of fullstack, hands-on experience with production systems - including backend services, frontend / UI, relational and document databases, caching, test automation

  • Experience with at least one modern frontend framework (preferably Vue)

  • Strong analytical skills and the ability to navigate large, complex codebases

  • The ability to model, architect, and implement web solutions from conception to delivery

  • A mindset focused on delivering business value to the customers, scalability, availability, performance and security across the stack

  • Ability to leverage LLMs to significantly increase productivity


Why join us?

  • Impact: Your work will help shape a platform used by millions worldwide

  • Robust tech stack: Java / Spring / Kotlin / Vue / TypeScript / PostgreSQL / Redis

  • Environment: A small team with zero bureaucracy, direct involvement with company founders, ability to learn how profitable SaaS is built

  • Hybrid flexibility: We work mainly together in our Wrocław office, while staying flexible for occasional remote days when personal matters or deep-focus tasks require it

  • Innovation-first: We embrace new technologies and AI-driven productivity


If you want to work on a product with a global footprint and be part of a core engineering team - we’d love to hear from you.
