Sr. Product Manager

About this role

Istari Digital builds the connective tissue for defense acquisition. Our platform lets engineering models, simulations, and digital threads move securely across primes, suppliers, and government program offices, so a system can be tested, trusted, and fielded in months rather than years. We work at the center of some of the hardest problems in defense acquisition: getting the right model, to the right person, at the right classification, at the right time. We are a small, senior team, and every hire changes what the company can do next. The role Istari is a platform for sharing and working on engineering data in highly regulated, no-fail industries — where a mistake can cost a mission, an aircraft, or a life. No single team builds a fighter: the airframe comes from a prime, the engine from one supplier, the radar from another, and the teams are separated by geography, classification level, corporate boundaries, and an ecosystem of software tools. Istari keeps their models, simulations, and test results connected so they can move fast and not break things. We’re hiring a Senior Product Manager to own a significant piece of that platform end to end. You’ll take a set of features that each solve a real problem and turn them into a product that hangs together — one coherent story for the customer, one coherent roadmap for the team. This is a role for someone ambitious who wants real ownership. You’ll get a problem space, direct access to customers, and a strong engineering team. From there, we expect you to figure out what matters: talk to users, find the shape of the problem, decide what to build and in what order, and carry it through to shipped. You’ll work directly with our Head of Product on strategy — your job is to bring a clear point of view to that conversation, not to wait for one. The domain is technical and we like it that way. Our users are systems engineers building spacecraft, hypersonic vehicles, and submarines. A single customer problem might span extracting proprietary CAD files into vendor-neutral formats, sharing data across air-gapped environments, and automatically re-checking mission requirements on every revision — which means our product touches engineering tools, SDKs, APIs, workflows, and secure infrastructure. You don’t need to be able to administer a Kubernetes cluster, but a conversation about one shouldn’t scare you — you need enough technical depth that engineers trust your judgment and customers trust your answers. You don’t need to have run a business or owned a massive roadmap. You do need to be comfortable in a room with senior stakeholders — a customer’s chief engineer, a program executive, our leadership team — and able to hold your own.
