Why This Job is Featured on The SaaS Jobs
This Senior Full Stack Engineer role stands out in SaaS because it sits at the intersection of an enterprise platform and frontier “agentic” AI, aimed at modernizing knowledge-work workflows. The listing signals a product with meaningful real-world usage (hundreds of customers across many countries), which typically brings the kind of reliability, security, and UX expectations associated with mature B2B SaaS—while still leaving room for foundational engineering decisions.
From a SaaS career perspective, the work maps to durable, high-leverage problem areas: building across the stack, supporting multiple product lines, and shipping customer-facing capabilities that must hold up under enterprise constraints. The technical themes called out—large-scale retrieval, multi-region GPU capacity, and evaluation frameworks—translate well to other AI-enabled SaaS categories where cost, latency, and governance become core product concerns rather than infrastructure afterthoughts.
This position is best suited to engineers who prefer end-to-end ownership and cross-functional collaboration, especially with domain experts outside engineering. It will likely appeal to professionals who want to stay close to product outcomes while working on platform primitives that other teams can build on, in an in-person environment.

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.
