📋 Description

• Build and maintain backend services using PHP, Laravel and Symfony. • Participate in technical discovery and help shape solutions before implementation starts. • Own initiatives through implementation, testing, release and production. • Design solutions before writing code, balancing speed, quality and long-term maintainability. • Write automated tests as part of development and take ownership of the quality of what you ship. • Use AI throughout development, testing, documentation and code review. • Collaborate closely with Product Managers, Quality Assurance Specialists and other engineers. • Continuously improve systems rather than adding unnecessary complexity. • Participate in daily engineering rituals such as refinement, planning, reviews and retrospectives.

🎯 Requirements

• Strong commercial experience with PHP and Laravel and/or Symfony. • Hands-on experience using Claude Code (preferred), Cursor or similar AI tools in real software development. • Strong understanding of microservices, REST APIs and modern backend architecture. • Experience with MySQL (MariaDB), MongoDB, Redis, Docker, Kubernetes and GitLab CI/CD. • You think beyond implementation, ask "why" before "how", and enjoy solving business problems—not just coding tasks. • You don't stop when the code is merged—you care whether the solution actually works in production. • You take ownership of quality, write automated tests and don't rely on someone else to catch your mistakes. • Backend is your strength, but you're comfortable stepping outside it when AI and established patterns make it practical. • You know the difference between "I can solve this with AI" and "this genuinely needs a specialist." • You're collaborative, pragmatic and comfortable discussing technical trade-offs with Product Managers and your teammates. • Communicative Polish and English.

🏖️ Benefits

• 100% remote — fully flexible, work from anywhere in Poland. • Travel voucher — annual "Work with Us, Travel with Us" perk. • English classes + dedicated team development fund. • Medical & life insurance — co-financed, plus sports facilities access. • 24 / 26 days off + 2 extra CSR days — plenty of time to recharge and give back to the community. • Company retreats & events , wedding & baby packs, employee referral program. • Flat hierarchy — open communication, no bureaucracy.
