[Remote] Senior Software Engineer, Vault

Note: The job is a remote job and is open to candidates in USA. Alt is unlocking the value of alternative assets through a platform for buying, selling, vaulting, and financing collectibles. The Senior Software Engineer, Vault will serve as the founding engineer for Alt Vault, automating physical-asset intake and quality control, building Vault-as-a-Service infrastructure and APIs, optimizing digitization workflows, and delivering full-stack product capabilities while mentoring the growing Vault team.

Responsibilities

• The vault pipeline, automated. Drastically reduce the time from item received to live on platform: intake automation, scan orchestration, and the quality-control tooling that catches a mis-scan before a customer does. If an item is mis-recorded, that isn't a data problem. That's someone's asset and someone's trust
• Vault-as-a-Service. Architect the account infrastructure, billing, and external APIs that let enterprise partners vault, ship, and manage assets programmatically. External partners behave unpredictably; the API has to hold anyway
• The digitization stack. Optimize card imaging and lighting pipelines, and help turn static front-and-back photos into 360-degree views for digital repackers
• The full stack, not half of it. 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. This is not a backend seat with a frontend disclaimer
• The team behind you. Level up a growing Vault team through code reviews, technical documentation, and mentorship
• Use vision models for quality control on the imaging line — flag a misaligned scan, a glare artifact, a label that doesn't match the manifest — so the exception surfaces before the item goes live rather than after a customer complains
• Build a partner-behavior simulator from an enterprise partner's own integration spec: malformed manifests, duplicate submissions, out-of-order webhooks, an SLA breach. Test the failure paths a sandbox will never give you
• Stand up an agent that triages the intake exception queue overnight, clusters what went wrong, and hands you a ranked list with a proposed cause per cluster instead of a backlog of one-offs
• Use models to bootstrap a new asset class: turn a grading authority's condition taxonomy and a pile of listing descriptions into a working schema and extraction pipeline for watches or sealed wax in days, not a quarter
• Put an MCP server over the vault inventory and event history so "where is this item and what happened to it" is a sentence, not another one-off query
• Use Claude Code or Cursor as the default way you work through a migration or a refactor, not as autocomplete

Skills

• 5+ years of backend experience (Python, Postgres, AWS or similar cloud infrastructure) and frontend experience (React, React Native, JavaScript/TypeScript). Both halves are load-bearing here
• A track record of owning features or systems from design to production. Design doc through shipped UI, not a ticket you closed
• Business-owner thinking. You understand P&Ls, SLAs, and what it takes to run a product as an independent business unit — not just ship code inside one
• A pull toward operational complexity. You're energized by problems that bridge software and the physical world: logistics, imaging, asset handling, partner integrations
• Pragmatism and pace. You know when to build custom and when to integrate, and you bias toward action
• Strong collaboration and communication. You write great docs, ask smart questions, and give thoughtful feedback
• A user-first mindset with a sharp eye for clean UX and performance
• Bonus: familiarity with the collectibles space or alternative asset marketplaces. Logistics, customs, or shipping systems experience. You collect
