Senior Product Manager

Codex is building the infrastructure for stablecoin-based cross-border payments — moving money faster, cheaper, and more transparently than the legacy financial system. Backed by Circle, Coinbase, Dragonfly, Wintermute, and Cumberland, we're a small team solving hard problems at the intersection of crypto and global payments.

The Role

As Senior Product Manager, you'll own 3P payouts and collections end-to-end — from how money flows in via virtual accounts and collections rails, to how it flows out via FP integrations and direct banking rails. You'll be the payments expert in the room: the person who knows which FPs are worth integrating, how to design a user journey for our clients, and how to specify something that an engineer can actually build.

What we need is someone who is deeply payments-native and can operate as the domain owner from day one.

• Own the 3P payout and collections product end-to-end — from strategy and prioritisation through to spec, build, and launch

• Define and maintain the product roadmap for FP integrations and direct banking rail integrations as the business scales

• Write detailed, buildable specs — engineers should be able to ship from what you produce

• Design the user journey and frontend experience for payout and collections flows, with strong opinions about what a client actually needs to see and do

• Evaluate FPs and banking partners across pricing, rail coverage, onboarding complexity, licensing constraints, and operational reliability — and make clear recommendations on which to integrate and in what sequence

• Lead the integration process with new FPs end-to-end: scoping, spec, coordination with Engineering, and go-live

• Understand the FOF implications of each FP and banking relationship, and design around the constraints rather than discovering them after the fact

• Stay current on the FP and payments infrastructure market — who the relevant players are, what they're good at, and where the gotchas are

• Work day-to-day with the co-founders, Customer Operations, and the Engineering team

• Align with Financial Partnerships on which FPs and banks are being evaluated, and feed product requirements into the partnership prioritisation process

• Work closely with Compliance and Legal on licensing constraints and fund safeguarding requirements

• Surface client feedback on payout and collections UX to inform the roadmap — you'll be talking to clients directly

• 6 to 10 years of product experience, with meaningful depth in cross-border payments infrastructure — payouts, collections, virtual accounts, and FP/banking integrations

• Must have shipped both directions of money movement: outbound payouts and inbound collections

• Prior hands-on integration experience with payment infrastructure providers Payments-native: you understand flow of funds, rail mechanics, corridor-specific constraints, and how licensing affects what you can build

• Opinionated about UX for a B2B payments ICP — you know what a client needs to see when they place an order, and you can design for it

• Background at a licensed cross-border payments company or stablecoin payments shop at Series A–C scale
