Job description

Join our Integrations team and help build a robust, scalable platform that connects our AI-powered translation and localization tools with hundreds of services our customers rely on daily. This is more than coding—it’s about architecting a system that makes workflows effortless, developer experience smooth, and enables product teams to deliver value faster.

Your responsibilities:

  • Lead design, development, and long-term ownership of the integrations platform and services.

  • Build scalable, multi-tenant systems using Node.js, PHP, microservices, and a PHP monolith.

  • Implement API integrations, webhooks, polling mechanisms, message queues, and event-driven architectures.

  • Improve development lifecycle, CI/CD, testing, observability, and operational excellence.

  • Mentor and elevate team skills through code reviews, knowledge sharing, and technical guidance.

  • Pioneer AI-powered development workflows and tools within the team.

🧠 Our requirements:

  • 7+ years building and maintaining complex backend systems.

  • Strong experience with Node.js and PHP, modern services, and monolithic architectures.

  • Proven experience in integrations: API versioning, message queues, event-driven architectures.

  • Solid understanding of APIs, relational databases (e.g., PostgreSQL), and cloud services (AWS or similar).

  • Strong judgment in system design and technical decision-making (PoCs, RFCs/ADRs).

  • Commitment to testing, observability, operational excellence, and high-quality code.

  • Experience with AI-assisted development tools (e.g., GitHub Copilot, Cursor).

  • Excellent problem-solving, communication, and leadership skills.

🌟 What we offer:

  • Stable employment in a fast-growing company

  • Flexible and remote-friendly working model

  • Health and wellbeing benefits

  • Continuous learning and development opportunities

  • Modern equipment and comfortable work environment
