About the role

Key responsibilities & impact

Automate the vault pipeline: Drastically reduce the time from item received to live on platform — building intake automation, scan orchestration, and quality-control tooling.
Expand beyond cards: Design and build ingestion, grading, and pricing workflows for non-card asset classes (watches, art, sealed wax) so Alt Values appear the moment items are vaulted.
Build Vault-as-a-Service: Architect the account infrastructure, billing, and APIs that let enterprise partners programmatically vault, ship, and manage assets at scale.
Ship the digitization stack: Optimize card imaging, lighting pipelines, and help turn static front/back photos into 360-degree views for digital repackers.
Own the full stack: Take features from technical design through polished UI — Vault touches real-world operations, and the product surfaces need to be as sharp as the backend.
Be a multiplier: Level up the growing Vault team through code reviews, technical documentation, and mentorship.
