Product Manager

Sandboxx builds consumer technology that supports service members and their families across the full military life cycle. We operate at national scale, work closely with the Department of War and the broader military ecosystem, and serve millions of users each year. We are looking for driven, curious people who take ownership of their work, move quickly, and want to build products that have real impact for the military community.

• This is a full-time W2, in-office position based in Middleburg, Virginia.
• We offer a generous relocation stipend to make your move smooth and stress‑free.
• Our office is dog‑friendly; your four‑legged friends are welcome here!

We're hiring a hands‑on Product Manager who thrives on turning ideas into shipped, measurable outcomes. You'll drive the execution and delivery of our flagship product, Sandboxx Letters, and partner closely on Waypoints, translating discovery work into prioritized backlogs, prototypes, and shipped features. You'll play a hybrid role, part product owner, part designer‑adjacent builder, and part scrum master, helping connect strategy to execution.

This is a high‑impact, hands‑on role on a lean team: you should be comfortable managing two product roadmaps, writing crisp PRDs, and turning those PRDs into clickable, AI‑enabled prototypes that engineers can iterate on and ship.

We're a mission‑driven team building products that matter. If you're motivated by purposeful work, enjoy end‑to‑end ownership, and have experience leveraging AI coding tools to move faster and build smarter, this role is for you.

While we offer the flexibility to hire remote talent for the right fit, we have a strong preference for in‑person collaboration at our Middleburg, VA headquarters and offer an enhanced compensation package for candidates willing to be onsite.

Sandboxx builds products that support the military community, connecting service members and their supporters, and developing solutions that matter to the family life cycle of service. We’re mission‑driven, scrappy, and growing new products like Waypoints while doubling down on our flagship product, Sandboxx Letters.

• Execution for Sandboxx Letters: manage roadmap delivery, backlog prioritization, feature launches, experiments, and KPI tracking for engagement and retention.
• Support for Waypoints: partner with leadership and design to turn discovery and research insights into actionable PRDs and prototypes.
• End‑to‑end delivery for features: PRD → prototype → engineering handoff → launch → measurement.
• Agile ownership: run sprints, retros, and backlog grooming sessions for a small cross‑functional squad; you’ve got a “do‑it‑all” mindset.
• Design partner: create and critique UI/UX work, maintain or help evolve our design system, and ensure product polish across platforms.
• AI‑forward prototyping: use AI tools and prototyping frameworks to rapidly test and validate new user experiences (LLM‑powered helpers for copy, auto‑translations, summarization, personalization, on‑device or cloud RAG flows, etc.).
• Cross‑functional communication: keep teams aligned through clear documentation, roadmaps, and stakeholder updates.
• Measurement: define success metrics, track impact, and use data to guide iteration.

• Write clear, outcome‑focused PRDs that include success metrics, user journeys, designs, and engineering acceptance criteria.
• Rapidly prototype PRDs into interactive mocks using Figma/Framer/Framer Motion (or similar), plus AI prototyping frameworks to demo LLM experiences.
• Collaborate with engineers to scope, deliver and accept features for mobile and web applications.
• Run Agile rituals (act as PO or Scrum Master depending on sprint needs) and maintain backlog health.
• Run discovery, conducting user interviews, surveys, data analysis, and small‑scale experiments.
• Prioritize ruthlessly for a two‑product portfolio; balance near‑term letter needs with Waypoints product experiments. Measure results and iterate: own instrumentation, dashboards, and experiments.
• Influence tradeoffs and decision‑making to ensure quality delivery and simple experiences.
