Job summary

Reap is seeking a Staff Engineer/Tech Lead to advance Agentic Payments. You will drop into existing payments rails and shape how AI agents execute transactions at scale, working with product and engineering teams across the platform.

You will own end-to-end features, collaborate with founders, and ship infrastructure across systems in a fully remote, async environment. Passion for fintech and AI-driven payments is a plus.

Qualifications

• 5-8+ years of professional backend engineering experience.
• Strong API design skills: designing clean, versioned, consumer-facing contracts.
• A track record of dropping into unfamiliar codebases and shipping quickly, using AI tools and modern development practices to move fast.
• Genuine, demonstrated engagement with the agentic-commerce space (protocols, card-network programs, or browser-automation infrastructure).
• Strong product sense: knows how to take a capability from idea to production without a detailed spec handed to you.
• Low ego and high adaptability: you build with the teams you join, not around them.
• Clear communication and the ability to work autonomously in a fully remote, async team.

Responsibilities

• Design and ship agentic capabilities, from card enrollment and spend controls to checkout execution.
• Work across both structured agentic-commerce protocols and custom checkout automation.
• Own agentic features end-to-end across team boundaries: build it where it needs to live, and operate it in production.
• Help shape the agentic payments roadmap, including deciding what needs to be built in the first place, then turn those decisions into shipped infrastructure.
• Collaborate directly with product, founders, and the teams whose systems you're embedding in.
