Product Manager

Product Manager

Sandboxx is the leading platform dedicated to finding and building technology solutions throughout a service member's military life cycle. We're looking for people with drive and initiative who are excited about making great technology and a positive attitude for our service members. Come help us build meaningful solutions for the military community!

• Full-time W2, in-office position based in Middleburg, Virginia.
• Generous relocation stipend.
• Dog-friendly office.

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.

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.
• 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 acceptance criteria, delivering 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.

• 3+ years of product management experience owning consumer mobile/web products (startup or small team experience preferred).
• Proven ability to manage two products or a product + new product incubator simultaneously and prioritize conflicting needs.
• Strong design sensibility, comfortable critiquing UI and interaction patterns, and shipping polished mobile experiences.
• Excellent PRD and product writing skills; you can create a document that engineers, designers, and executives all understand and act upon.
• Hands‑on with…
