Sandboxx is looking to build and improve technology solutions for service members throughout their military life cycle, specifically focusing on their flagship product, Sandboxx Letters, and a new product called Waypoints. The company aims to connect service members with their supporters and develop meaningful solutions for the military community.

Requirements

  • Hands-on with prototyping tools (Figma required; experience with Framer, ProtoPie, or full-stack prototyping a plus). You can turn a PRD into a clickable prototype with real AI behavior.
  • Practical experience building or prototyping AI features (LLMs/Generative AI): prompt design, human-in-the-loop, RAG, basic evaluation/metrics for LLM experiences.
  • Strong analytical instincts and experience with analytics (Amplitude, Firebase, Mixpanel, or similar).
  • Background working with mobile SDKs, backend APIs (Python/Go), or experience working closely with GraphQL backends.
  • Prior experience building AI into consumer-facing mobile apps and running live experiments.
  • Experience with shipping subscription or commerce features (letters have fulfillment/physical shipping elements).
  • Certifications: CSPO/CSM/PMP or similar.

Responsibilities

  • Manage roadmap delivery, backlog prioritization, feature launches, experiments, and KPI tracking for engagement and retention.
  • 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.
  • Run sprints, retros, and backlog grooming sessions for a small cross-functional squad, you've got a "do-it-all" mindset.
  • Create and critique UI/UX work, maintain or help evolve our design system, and ensure product polish across platforms.
  • 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.).
  • Define success metrics, track impact, and use data to guide iteration.

Other

  • 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.
  • As the product owner and Scrum Master on a lean team, you can lead ceremonies and execute tactical tasks.
  • Excellent cross-functional communication and stakeholder management skills.
  • Mission aligned: You care about serving the military community and building products that matter.
