Why This Job is Featured on The SaaS Jobs
Backend platform work is a recurring differentiator in enterprise SaaS, and this Staff Software Engineer role sits squarely in that layer. The remit spans core primitives—authentication, permissions, feature flags, and notifications—alongside collaboration and admin capabilities that typically underpin multi-tenant, security-conscious products. The listing also signals an AI-enabled SaaS serving professional services, where reliability and data handling constraints shape engineering decisions in ways that differ from consumer software.
For a SaaS career, the long-term value here is depth in “platform as product” thinking: building internal infrastructure that accelerates multiple product lines while still shipping customer-facing capabilities. Experience with RBAC, auditability, integrations, and cross-organization workflows tends to transfer across B2B SaaS categories, especially those selling into regulated or high-trust environments. The cross-functional collaboration mentioned also reflects how mature SaaS teams connect engineering choices to product and go-to-market needs.
This role best fits an engineer who enjoys operating at the intersection of systems design and practical delivery, and who is comfortable owning foundational components that other teams depend on. It aligns with professionals who prefer ambiguous problem spaces where security, privacy, and operational excellence are first-order concerns, and who want to influence technical direction without moving fully away from hands-on building.
The section above is editorial commentary from The SaaS Jobs, provided to help SaaS professionals understand the role in a broader industry context.
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 700+ 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.
