Senior Software Engineer, Vault

Alt Platform Inc • New York, NY

12d • $200,000 - $220,000 • Remote

About The Position

Alt is unlocking the value of alternative assets, starting with the $5 B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place and we are backed by leaders at Stripe, Coinbase, Seven Seven Six, and pro athletes like Tom Brady and Giannis Antetokounmpo. Our next frontier is real-time pricing at scale—the Alt Value that powers every trade, loan, and product on the platform.

We're building Alt Vault into a standalone business, and you are its founding engineer. That means automating intake, scan orchestration, and quality control so items go live fast. It means extending the whole system beyond trading cards. And it means shipping Vault-as-a-Service — the account infrastructure, billing, and APIs that let enterprise partners programmatically vault, ship, and manage assets at scale.

The metric: time from item received to live on platform. Drive it down, and keep driving it down as the asset classes multiply.

This is software that touches the physical world, which means it fails in physical ways.. If you like operational complexity, if you think in P&Ls and SLAs rather than just tickets, and if the phrase "nobody has built this yet" reads as an opportunity rather than a risk, this is the seat.

Requirements

• 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.

Nice To Haves

• Familiarity with the collectibles space or alternative asset marketplaces.
• Logistics, customs, or shipping systems experience.
• You collect.

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.

Benefits

• We cover 85% of your medical, dental, and vision, and up to 50% for dependents.
• HSA/FSA available
• Flexible PTO that people actually take
• Parental leave at full salary
• $200/month wellness + $100/month home office stipend
• Free DoorDash membership
• Remote-first (for most positions), with WeWork access when you want a room with other humans
• 401(k)
• Alt Equity to all full-time employees
