At Qualifyze, software engineering is more than just writing code, it’s about shaping the future. We’re looking for engineers who understand that every line they write contributes to tomorrow’s legacy. On our team, you’ll focus on shortening feedback loops, building scalable solutions, and maintaining clear communication with the business. You’ll champion clean architectures, solid testing strategies, and domain-driven design principles to ensure we deliver real value, every step of the way.

Main responsibilities

- Guide backend architecture, testing,



and technical decisions across teams, ensuring scalable, high-quality delivery and adherence to best practices.
- Own and solve complex tasks within large projects, or lead small projects independently.
- Communicate and collaborate effectively with team members, the DevOps team, product managers, and the design team. You will lead the technical approach translating product requirements into clear, functional solutions.
- Mentor peers and support pragmatic decision-making, balancing business priorities with technical needs.
- Follow, contribute to, and ensure adherence to our team’s working agreements.
- Work autonomously, taking ownership of stories, programming, and coordinating tasks without external assistance.

Main requirements

- We’re looking for a strong backend engineer. Experience with our tech stack is a plus, but what matters most is solid backend expertise and alignment with our ways of working.
- Pragmatic approach to technical solutions.
- Proficient in clean architectures, good practices and testing
- Hands-on experience with event-driven systems.
- Experience with databases such as PostgreSQL.
- Nice to have: experience designing systems with security and compliance by default, following best practices for regulated environments.
- You’ll be working in an international environment, so daily communication will be in English.
