About the Job

Requirements

  • At least 8 years of production software development experience, including at least 4 years building payment systems that moved real money at scale at a payment service provider, card issuer, processor, or commerce platform payments team.
  • Hands-on card payments experience, including card issuing or processing and the ability to debug authorization, clearing, settlement, refunds, and chargebacks at the network level.
  • Experience with network tokens or a card vault, designing systems within Payment Card Industry Data Security Standard (PCI DSS) scope, and deliberately limiting that scope.
  • Deep experience integrating payments into checkout flows across many merchants or payment service providers, including 3-D Secure (3DS), partial failures, and changing totals.
  • Experience building idempotent application programming interfaces (APIs), retries, and reconciliation against independently computed values, and owning a ledger or money-movement system through real incidents.
  • Experience setting architecture from first principles on a multi-month project, starting from a problem statement, defending the architecture, and delivering work other engineers build on.
  • Strong TypeScript skills, ability to build APIs and interfaces, and daily use of artificial intelligence tools with evidence of improved work speed without reduced quality.

Responsibilities

  • Build card issuing and tokenization for agents by issuing and managing virtual cards and network tokens scoped to an agent, merchant, or purchase, and integrating card-network agent programs as they mature.
  • Make checkout reliable across a wide range of merchants with differing purchase flows, changing totals, and steps that may expect human involvement, using direct integrations, agentic commerce protocols, and browser automation as needed.
  • Translate owners’ spending rules into authorization-time controls that prevent agents from spending beyond approved limits.
  • Build idempotent payment flows, retries, and reconciliation against processor and network records to correctly resolve payments that time out or become unresponsive and prevent duplicate charges.
  • Maintain a versioned record of what the buyer saw and agreed to that can support disputes or chargebacks months later.
  • Design and build the public API, software development kits (SDKs), and tools agents call, with contracts models can use correctly, and build the interface on top of the systems.
  • Partner with counsel and compliance on PCI DSS, card-network rules, and money movement, and design systems that keep card data out of unnecessary locations.

Desired Qualifications

  • Experience with agentic payment protocols or card-network agent programs such as Visa Intelligent Commerce, Mastercard Agent Pay, ACP, or AP2; browser automation or request interception; or disputes and fraud systems.
  • Experience shipping a tool that a large language model calls, or setting architecture at an early-stage company rather than inheriting it.

About the Company

Sapiom

AI agent infrastructure for production deployment

Sapiom provides an infrastructure platform for developers to build, deploy, and manage AI agents in production. It acts as a clearing layer between agents and third-party services, enabling autonomous access to APIs, cloud compute, and data while handling payments and governance; it includes Sapiom Router for real-time LLM routing, Agent Studio for building and testing agents, and Runtime for managed production with observability, budget controls, and security policies like Know-Your-Agent (KYA). The company differentiates itself through cost optimization, real-time model routing, and agent spend governance to scale the agentic economy. Its goal is to make agent-driven automation scalable and reliable by reducing costs and giving teams control over how AI agents access resources and transact for programmatic commerce.
