Third Line Solution Engineer

The Third Line Solution Engineer role

We’re a fast-growing software company offering an innovative API-based SaaS e-commerce platform. We started by empowering small and mid-size fashion & lifestyle brands, and as we’ve scaled, so have our clients. Today, we’re proud to partner with major enterprise brands, helping them make their mark globally.

Our platform is designed to be the best in the world, and we’re building a team that shares the same ambition. Though we’re a young company, we’ve already captured widespread attention and work with some of the strongest brands in the Nordics, along with clients across Europe, North America, and Asia. As we continue to grow, we have ambitious plans to expand our team and take on new challenges. And we’re not stopping there—this is just the beginning, with even more exciting opportunities and growth on the horizon. There’s never been a better time to join us on this journey.

This role is based in Wrocław, Poland, and we encourage our teams to connect in person at our city-center office. We value the time spent collaborating face-to-face— whether it’s brainstorming together or simply enjoying a cup of coffee.

At Centra, we’re looking for someone who’s not only highly skilled but also eager to learn and solve challenges together as a team. We work with passion, pushing boundaries, and we owe our success to the ambitious and talented people we hire. As we continue to grow, we are seeking more individuals who share the same mindset.

We’re currently seeking a motivated and experienced Third Line Solution Engineer to take an active role in strengthening the technical foundation of our global e-commerce platform.

This year, our priorities include advancing our headless infrastructure, streamlining internal processes, and expanding our API landscape. In this role, you’ll tackle complex challenges, collaborate across teams, and contribute to delivering reliable, high-quality technical solutions.

What we're looking for

• Strong English communication skills (min. B2 level).
• Proficiency in reading and scripting PHP; ability to assess backend systems and data structures. Familiarity with Xdebug is a plus.
• Basic knowledge of writing, testing, and maintaining code is a plus, especially when it helps improve the product or resolve issues (not a must-have).
• Bachelor’s degree in Computer Science, Information Technology or a related field – or equivalent hands-on experience.
• Solid understanding of SQL with the ability to interpret database structures and write effective queries.
• Good grasp of HTTP communication (methods, status codes) and how APIs enable systems to interact.
• Experience with e-commerce systems—particularly headless setups—and working with APIs such as REST and GraphQL.
• Familiarity with logging and monitoring tools like Kibana, Grafana, or similar.
• Clear communication skills, with the ability to explain technical matters to non-technical stakeholders.
• A client-first mindset, combined with a proactive and creative approach to support and problem-solving.
• Familiarity with tools like Docker, various IDEs, and Git is considered an asset.

Team

All teams work within the boundaries of the Scrum framework. We try to avoid having long meetings (or having a lot of them), and we put a lot of focus on fast and efficient communication inside the team (Slack, Google Meet, face-to-face).

Our Benefits

• Enel-med medical insurance plan to keep you healthy
• Sport card and a pack of fitness buddies to join you on your journey to getting fit and strong
• Body-healing massages in the office
• Set of cutting-edge equipment (MacBook Pro, AirPods and other)

Self Development

• A non-hierarchical work environment where you’ll have a lot of impact and space for growth
• A budget for participating in educational programs, meet-ups, and other events related to your profession

Feel at home

• A multicultural environment where you always belong, no matter your ethnicity, gender, religious, or social background
• Casual dress atmosphere. Wear whatever makes you feel good
• We love animals, so from time to time, you can also take your animal companion to the office
• Regular table football tournaments and lunch break face-offs
• Team-building events and friendly afterworks
