Sandstone is building an AI-native legal platform that amplifies in-house legal teams rather than replacing them. The platform unifies legal data, powers end-to-end workflows, and organizes business context within tools teams already use. The company is trusted by Fortune 500 companies and fast-growing innovators, with an elite engineering team and world-class designers.
As Founding Product Manager, you will help realize the vision of a single pane of glass for in-house legal teams. You'll own a product vertical and play an integral role on the product leadership team. You may also lead customer enterprise deployments and/or a set of integrations.
Key responsibilities include:
- Own the product roadmap for one vertical: decide what to build, prioritize ruthlessly, and ship continuously
- Set product feature timelines and team goals aggressively but pragmatically
- As a member of the product leadership team, help decide the future of the product roadmap and how Product works at Sandstone
- Move fast on two-way doors and ship to learn; for irreversible decisions, map scenarios and pressure-test paths
- Partner with AI & ML engineers to define what "great" looks like for agentic workflows (accuracy, reliability, latency, human-in-the-loop moments)
- Spend time with General Counsels, legal ops leaders, and day-to-day users; sit in on sales and post-sales calls to study real-world workflows
- Work closely with Engineering, Design, Forward-Deployed Engineers, and GTM teams
The role is based in Lower Manhattan (Lower East Side office). The company works five days a week in-office. Dogs are welcome; shoes optional; chess encouraged.
REQUIREMENTS:
- 6+ years in product management, ideally including time at an early-stage, high-growth startup where you helped carry the company through a step change in size
- Track record of shipping 0-to-1 products and then scaling them, with measurable outcomes
- Ability to earn the trust of strong engineers by being useful, being right often, and knowing which projects don't need you
- Comfort managing complex systems, mapping genuinely complex workflows, and translating them into products that feel simple
- Demonstrated track record of entrepreneurship or success in an unstructured environment; hungry, low ego, and generative
- Empathy to understand what a customer is feeling and emotional intelligence to know what would feel natural to them
BONUS:
- Experience in legal tech, legal operations, or building products used by in-house legal teams
- Technical enough to prototype, read a PR, or stress-test an approach with engineering before it becomes a spec
