About the Role

Alt is unlocking the value of alternative assets, starting with the $5B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place. Your job is to turn the manual loan process into a product by implementing our new underwriting design, automating the loan workflow end-to-end, owning disbursement failures, and shipping the borrower and operator experiences. The north star is the T7 (trailing 7-day) Disbursement within SLA rate, with a target of 99%.

Responsibilities

  • Implement the new underwriting design in collaboration with data scientists.
  • Automate the loan workflow from application to disbursement and servicing.
  • Own and resolve disbursement failures at their root cause.
  • Ship borrower and operator experiences based on provided designs.
  • Implement the cash advance offer, acceptance, disbursement status, repayment, payoff, and loan history screens.
  • Build internal tooling for Credit, Operations, and Support teams.
  • Manage loan servicing functions including auto-pay, partial payments, and payoff quotes.
  • Integrate money movement with the ledger for accurate posting and reconciliation.
  • Implement risk controls within the workflow, such as limits and holds.
  • Conduct rigorous code reviews and provide technical documentation.
  • Mentor other engineers on the Credit team.
  • Partner closely with Design and Data Science teams.
  • Stand up an agent to triage the disbursement exception queue.
  • Build a rail simulator to test disbursement failures.
  • Use models to generate adversarial test cases for the loan state machine.
  • Create typed component scaffolds with tests rapidly.
  • Implement an MCP server over loan and disbursement history.
  • Use AI tools for migrations and refactors.
  • Build a harness to replay historical applications through old and new underwriting logic.
  • Determine what should not be handed to a model in credit decisions and financial code.

Requirements

  • 5+ years building and scaling production applications across the stack (backend: Python, Postgres, AWS; frontend: React, React Native, TypeScript).
  • Experience building or owning a lending, credit, or payments workflow in production.
  • Experience moving real money on real rails (ACH, RTP, FedNow, wires).
  • Proficiency in workflow and state-machine design.
  • Strong operational debugging skills.
  • Ability to implement complex designs faithfully and quickly.
  • Database mastery, including expert SQL and relational design.
  • API-native understanding (webhooks, idempotency, eventual consistency, reconciliation).
  • Product-owner mindset with an understanding of fund flows.
  • Pragmatic approach to problem-solving.
  • Experience implementing credit decisioning or underwriting logic in production alongside data scientists.
