We also power the customer-facing release management experience, where each customer can view available features, discover new capabilities, opt-in and self-serve access to early releases. Our work spans features and feature flag management, feature gating, and the infrastructure that ensures features are launched safely, reliably, and with the right visibility for every audience. As a Senior Full-Stack Engineer on the Release Management team, you will design and build the internal tools and customer-facing experiences that make feature lifecycles safe, scalable, and transparent. You will collaborate across product and engineering teams to ensure features are discoverable, gated appropriately, and delivered with minimal risk, while also shaping how customers interact with and adopt new features.

*   Collaborate with product managers, engineers, and stakeholders to streamline how features move through their full lifecycle.
*   Enhance the customer-facing release management experience to improve feature discoverability and adoption.
*   Continuously improve code quality and system health, contributing to best practices and raising the technical bar for the team.
*   Champion, role model, and embed Samsara’s cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team) as we scale globally and across new offices

**Minimum requirements for the role:**

*   5+ years of relevant industry experience in software development
