• Use AI tools to speed up debugging, writing documentation, creating test cases, and summarizing incidents—while keeping quality and security intact.

We value

• High performance / results-first: solving the real problem and preventing it from coming back.
• Ownership: take responsibility for issues from report → diagnosis → fix → follow-up.
• Systems thinking: understand how changes affect reliability and users.
• Fast execution with integrity: speed and safe changes.
• Continuous improvement: learn, document, automate, and level up our support maturity.

You’ll thrive here if you…

• Enjoy debugging and turning messy issues into clear fixes.
• Communicate well under uncertainty (and ask good questions early).
• Like working close to real users and real production constraints.
• Prefer practical improvements over process theater.

What we’re looking for

• Around 3+ years of software development experience with Laravel, Yii.
• Solid fundamentals: OOP, clean code practices, and version control with Git.
• Basic experience with AWS and cloud environments (e.g., S3/ECS/RDS — not necessarily deep expertise).
• Working knowledge of PostgreSQL and MongoDB: writing queries, debugging data issues, understanding indexes at a basic level.
• Comfortable with Docker-based local development and working with CI/CD pipelines (at least as a user).
• Strong problem-solving skills, attention to detail, and a service mindset toward internal/external users.
• English: Upper-Intermediate+ for collaboration and documentation.
• Language bonus:
  • Swedish is a plus.
  • Ukrainian/Russian is a plus for smoother communication with part of the team.
• AI usage experience: practical experience using AI tools to support development/support workflows (we’ll support and compensate relevant subscriptions).

Interview process (3 steps)

1. Screening interview with the Recruiter.
2. Technical interview with the Tech Lead + practical debugging/support task.
3. Final approval interview with the CTO.
