About the Role
This is a high-autonomy engineering role at the intersection of AI and financial infrastructure. You'll design and ship core systems for agentic payments end-to-end, working across the full stack — backend, integrations, platform, and beyond. You'll operate as a true owner, making real technical tradeoffs and shaping product direction alongside the founding team, with AI tools embedded throughout the workflow.
Responsibilities
- Own end-to-end delivery of systems — from design to production — with minimal direction
- Make pragmatic architectural decisions in ambiguous, fast-moving contexts
- Move across the stack as priorities shift, without waiting for perfect structure
- Contribute to product and engineering direction alongside the founding team
- Scale systems thoughtfully for reliability, performance, and operational speed
Requirements
- Strong software engineering fundamentals and coding ability
- High agency and strong product/ownership mindset
- Systems thinker who can work through ambiguity
- Comfortable moving across different parts of the stack
- Bias toward shipping and making pragmatic decisions
- Actively uses AI-native development tools in their workflow
- Excited by fast-moving, high-intensity startup environments
- Experience at high-growth startups
- Experience building infrastructure, platform, or developer tools
- Familiarity with AI/ML systems, inference, or agent workflows
- Experience with payments, APIs, or distributed systems
- Experience in highly autonomous engineering teams
About the Company
- AI agents are beginning to act on behalf of companies and users — making purchases, spinning up compute, triggering workflows, and interacting with third-party systems. But today's financial infrastructure was built for humans, not autonomous systems. Companies and developers need a way to give agents controlled access, meter actions, monetize usage, and transact across rails, without rebuilding payments, risk, and compliance internally.
- Sapiom builds the financial payments infrastructure for the machine economy - autonomous spend rails that enable AI agents to transact with real-world services safely, processing every dollar spent, every policy decision navigated, and every risk signal generated.
- We have assembled a world-class team with deep payments and infrastructure DNA to build the operating system for machines. Backed by a $15.75M investment from Accel, Menlo, and Anthropic, we are moving with relentless focus to deploy the economic substrate for autonomous agents.
