About The Role 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. Key Responsibilities: Own the architecture and technical direction for core platform domains used by both squads (e.g. event-driven workflows, modular boundaries, AI capabilities). Spend 60–80% of your time hands-on: designing, coding, reviewing, pairing, and debugging in Laravel, Next.js and our cloud environments. Lead the technical discovery and delivery of high-impact initiatives, especially those that cross team boundaries or require significant architectural change. Define, document, and evangelize architectural principles, coding standards, and patterns for scalable, resilient, observable systems. Raise the bar for quality: champion shift-left testing, CI/CD improvements, and production observability; model best practices in test design and validation. Mentor senior and mid-level engineers through design reviews, pairing, and feedback, helping them own systems end-to-end rather than taking work away. Evaluate and prototype emerging technologies (e.g. Vertex AI, GenAI workflows, data pipelines) and guide pragmatic adoption into product and platform. Act as a senior engineering voice in roadmap planning, estimation and trade-off decisions, ensuring technical health is represented alongside product goals Works across both product squads rather than being embedded in one team, focusing on cross-cutting systems and the hardest technical problems. Partners with the Engineering Leadership on long-term architecture and with Tech Leads on execution and engineering practices.
