As a Principal Software Engineer at Rosterfy, you are the most senior individual contributor in the engineering team, responsible for setting technical direction while staying deeply hands-on. You work across our two product squads as a force multiplier: designing architecture, pairing on hard problems, and unblocking delivery on critical initiatives. Reporting to the HoE, you connect product strategy to implementation detail, ensuring the client’s v3 (event-driven, domain-driven, AI-augmented) is robust, scalable, and maintainable across our PHP/Laravel backend, Next.js frontend, and AWS/GCP infrastructure. You spend a significant portion of your time building (coding, reviewing, debugging, pairing) while also shaping engineering standards, architecture, and long-term platform evolution. You do not manage people directly; instead, you lead through technical excellence, influence, and mentoring.
