Senior Full-Stack Software Engineer

About Sandstone Sandstone is on a mission to elevate in-house legal from a support function into a true strategic partner. From day one, we've been clear about what we are-and are not. We are not replacing in-house legal teams. We are building a platform that amplifies them. Our platform enables modern legal teams to move at the speed of AI, deliver better outcomes, and create measurable business value. We unify legal data, power end-to-end workflows, and organize business context within the tools teams already use. Sandstone is the home for AI-native legal departments. Today, Sandstone is trusted by Fortune 500 companies and fast-growing innovators alike. We ship quickly, iterate relentlessly, and scale with intention. When you join Sandstone, you become part of a team that believes deeply in the compounding power of collaboration, rigorous problem-solving, and obsessive attention to detail. Our engineering team is elite, our lawyers ship code every day, and we are dedicated to building the most delightful product an in-house lawyer opens in the morning-and closes at the end of the day. We work five days a week out of our offices in the Lower East Side. Dogs welcome; shoes optional; chess encouraged. The Role We are inviting applications from engineers or builders - this is a generalist role for high-agency, versatile makers. At Sandstone, everyone wears multiple hats and contributes directly to our products and culture. "Ship relentlessly" is a core value of our team: we are all builders, and we expect you will be, too. You'll not only execute as an engineer but also play a key role in shaping product thinking, implementing customer feedback, and collaborating across functions. You'll touch multiple parts of the codebase and be hands-on with our products.
