Senior Technical Product Manager

About XFX

XFX is building the settlement and liquidity infrastructure for the programmable financial system. We unify fiat and blockchain rails into a single operational layer, enabling better execution quality, faster settlement, and higher capital efficiency for global money movement.

We launched in August 2025 and are already processing $4B in annualized volume with a growing roster of institutional clients. Stablecoins are rewriting the rules of cross-border payments and settlement, and the infrastructure layer to support that shift is still being built– that's exactly what we’re here to do.

We're a lean, global team of 10 with the conviction that it's never been a more exciting moment to build in this space. We work remotely across the US, Mexico, and Argentina with meaningful equity and real ownership over what gets built — backed by world-class investors including Castle Island Ventures, Haun Ventures, Oak HC/FT, MAYA Capital, Coinbase Ventures, Paxos, and Bitso.

The opportunity

We're looking for a Technical Product Manager to be the connective tissue between our Engineering and Operations teams — the person who lives in the details of system design, owns the build lifecycle from discovery through deployment, and ensures we're shipping with the precision and rigor that financial infrastructure demands.

This role requires deep familiarity with trading systems, capital markets infrastructure, or cross-border payments — and the technical fluency to operate at the intersection of all three. If you enjoy getting in the weeds of technical systems, love writing PRDs or prototyping new flows, and can hold the line on quality without slowing teams down, we want to meet you.

What you’ll do

• Own the build, end to end. Lead product discovery, requirements definition, development, testing, and deployment across core systems and third-party integrations — ensuring a high quality bar and world-class execution.
• Drive product clarity. Write PRDs or prototype new flows that clearly translate business goals into well-scoped technical requirements and execution plans. Be the primary product voice in engineering standups, sprint planning, and architectural discussions — unblocking teams and driving decisions daily.
• Go deep on system design. Partner with engineers on architectural decisions, data flows, API design, and integration patterns as an active thought partner.
• Own QA strategy across APIs and web UI, with a sharp focus on correctness, edge cases, and failure modes.
• Bridge engineering and operations. Serve as the primary liaison between Engineering and Operations, ensuring new capabilities land with the workflows, controls, and auditability needed to run them — while partnering with Compliance to build automation that scales.
• Contribute to shape our AI-enabled systems. Work with data and engineering teams to design and evolve our predictive and decision engine.

What we're looking for

• 5+ years of product management experience, ideally building trading, fintech, crypto, infrastructure, or AI-enabled systems.
• Fluency in payments, FX, or capital markets infrastructure — you understand concepts like settlement, netting, and liquidity management, or can get there fast.
• Comfort in system design conversations — APIs, data flows, backend integrations, reconciliation logic, and architectural tradeoffs aren't abstractions to you.
• Experience shipping in high-growth startups and know how to move fast.
• Strong verbal and written communication skills — you're great at translating action into writing, and know the importance of this in a remote-first environment.
• Data-oriented, pragmatic, and willing to make good decisions with incomplete information.
• Track record of setting direction and creating clarity, and you value follow-through and execution.
• Curious about emerging AI infrastructure and new tooling. You bring that curiosity to your day-to-day work.
