Payment Operations Manager, APAC

Job Title: Payment Operations Manager, APAC
Department: Trading, Treasury & Account Management
Reports to: Co-Founder
Location: APAC

About Codex
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
Codex is scaling its client base rapidly across APAC — and the operational infrastructure that keeps those clients active, funded, and trading needs to scale with it. As the Payment Operations Manager, you'll own the full post-onboarding client experience: treasury and settlement operations, client activation, and the processes that turn a newly onboarded account into a consistently trading one.

This is a hands-on senior role. You'll be doing the work yourself — moving money, resolving settlement issues, running penny tests, and staying close to clients — while building the systems and playbooks that allow the function to scale beyond you. You'll work closely with the trading and account management team.

Responsibilities

Treasury & Settlement Operations

• Manage intraday treasury balances across fiat and crypto accounts, ensuring settlement capacity is available for active clients across APAC trading hours

• Oversee end-to-end settlement for client trades — tracking traded-and-settled vs traded-and-not-settled positions, resolving delayed or failed settlements, and coordinating with banking and crypto counterparties on exceptions

• Handle escalations for rejected or undelivered wire transfers; coordinate with banks and payment providers to trace and resolve stuck payments

• Monitor and reconcile fund movements across accounts (fiat rails, on-chain networks), flagging discrepancies and maintaining clean records

Client Onboarding & Activation

• Own the operational side of client onboarding: penny testing new fiat and crypto accounts, configuring counterparties, whitelisting wallets, and coordinating demo calls

• Build and implement client activation strategies — structured playbooks that take a newly KYB-cleared account from zero to first trade as quickly as possible

• Serve as the senior operational point of contact for APAC clients through onboarding and early activation, setting expectations and resolving friction before it becomes churn

Process Building

• Document and systematise current operational processes — identifying what's manual, what's fragile, and where automation or tooling would have the most impact

• Work with Engineering and Product to translate operational pain points into product improvements

• Build the operational infrastructure — runbooks, escalation protocols, handover standards — that allows the team to grow without quality degrading

What We're Looking For

• 6–10 years of experience in payment operations, trading operations, or client operations at a crypto OTC desk, exchange, or digital asset firm

• Hands-on experience with treasury management and settlement across fiat and crypto rails — you've moved money, resolved failures, and understand what goes wrong and why

• Track record of building and implementing client activation processes, not just executing within ones someone else built

• Strong client-facing skills: able to manage relationships with institutional and fintech clients professionally, even when resolving operational issues

• Comfortable doing individual contributor work at a senior level — this is not a people management role, it's a builder role

Nice to Have

• Prior experience at a company scaling its APAC client base rapidly

• Understanding of crypto market microstructure and OTC pricing mechanics

• Experience with account management : understanding why clients churn, what it takes to bring them back, and running structured reactivation campaigns

• Experience maintaining customer success processes that create consistency across the client experience — from first trade through to high-volume, recurring flow
