You will also own the developer-facing frontend in TypeScript and . This is a hands-on technical leadership role. You will ship production code daily own critical subsystems end-to-end and set the technical bar for the team.

Key Responsibilities

As a Principal Software Engineer and team lead you will:

Own architecture and system design for core platform services ensuring they meet reliability security compliance and performance requirements.
Lead end-to-end delivery of critical platform capabilities from technical discovery and design through implementation rollout and ongoing improvements.
Drive technical excellence in the codebase setting standards for code quality testing performance and observability and ensuring they are adopted across the team.
Mentor and grow senior engineers providing clear technical direction constructive feedback and opportunities for ownership.
Collaborate with product platform and security leaders to translate business needs into technical roadmaps and make thoughtful trade-offs between speed safety and maintainability.
Continuously improve platform operability including deployment strategies telemetry and alerting incident response practices and post-incident learning.
