Why This Job is Featured on The SaaS Jobs
Harvey sits in a part of the SaaS ecosystem where enterprise expectations meet modern AI product delivery. A Staff Full Stack Engineer focused on platform primitives like permissions, feature flags, and notifications is positioned at the control plane of a multi-product SaaS, where consistency, governance, and reliability shape every downstream customer experience. The legal and professional services context also implies high sensitivity around data handling and auditability, which raises the engineering bar in ways that translate well across regulated SaaS categories.
For a long-term SaaS career, this kind of platform-plus-product scope builds durable leverage. Work that spans shared infrastructure and enterprise-facing collaboration features tends to deepen judgment around multi-tenant design, rollout strategy, and cross-team enablement. It also strengthens the ability to balance iteration speed with operational discipline, a common inflection point as SaaS companies scale usage, customers, and internal engineering surface area.
This role is best suited to senior engineers who like owning foundational systems while still shipping user-visible capabilities. It will fit someone comfortable navigating cross-functional tradeoffs and setting technical direction, especially where security and reliability requirements are first-class constraints rather than afterthoughts.

Job Description
Why Harvey
At Harvey, we’re transforming how legal and professional services operate — not incrementally, but end-to-end. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.
This is a rare chance to help build a generational company at a true inflection point. With 1000+ customers in 58+ countries, strong product-market fit, and world-class investor support, we’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched.
Our team is sharp, motivated, and deeply committed to the mission. We move fast, operate with intensity, and take real ownership of the problems we tackle — from early thinking to long-term outcomes. We stay close to our customers — from leadership to engineers — and work together to solve real problems with urgency and care. If you thrive in ambiguity, push for excellence, and want to help shape the future of work alongside others who raise the bar, we invite you to build with us.
At Harvey, the future of professional services is being written today — and we’re just getting started.
