Engineering Manager, Treasury

As Engineering Manager, Treasury at Reap, you lead the team building global, asset-agnostic money movement systems that work across regions, currencies, and financial partners. The Treasury team operates the core infrastructure underneath every Reap product: incoming and outgoing flows, fiat and stablecoins, wallets and custody, internal transfers, withdrawals, and payouts. You'll be deeply involved in the architecture and operation of wallet infrastructure, key management, signing, and reconciliation flows while developing the engineers around you. You'll partner closely with the Head of Treasury and Reap's product organization to turn treasury strategy into systems that hold up in production.

What you'll do

• Own the engineering side of the Treasury domain: assets and currencies, rails and networks, FX, wallet and account infrastructure, and the global ledger, building the foundation that lets Reap launch new hubs and markets
• Lead the design, development, and operation of core treasury systems while staying hands-on enough in the architecture to make and defend real technical decisions
• Lead wallet and custody integrations end to end, from provider evaluation and key management design through to production operation and reconciliation
• Develop a deep understanding of Reap's clients, product suite, and hubs, and use it to make opinionated, well-reasoned technical calls
• Work closely with product, engineering, design, finance, customer success, and business operations to drive outcomes across Reap's global hubs
• Communicate technical decisions, rationale, and tradeoffs clearly to company leadership and key stakeholders
• Grow and shape the Treasury engineering team through hiring, operating model design, and long-term roadmap development
• Drive technical decision-making while supporting the growth and performance of the engineers on your team
• Define and build systems that compound in capability and scale, and that can be orchestrated across all of Reap's global hubs
• Build observability into every layer, lead incident response, and drive continuous reliability improvements
• Define and measure success metrics for continuous improvement, using data to get 1% better every day
• Maintain a high bar for quality, caring about the details of how something works and scales, not just whether the v1 shipped
• Stay current with fintech, infrastructure, and compliance trends, and evolve systems accordingly
• Actively use AI tooling to accelerate your own output in design exploration, code review, debugging, spec writing, and technical synthesis
• Help embed AI-native practices across the team and identify opportunities to build AI-assisted capabilities into the systems themselves
• Be part of Reap's engineering leadership, helping build the foundational systems that power Reap's ambitions

What you bring

• Minimum 8 years of software engineering experience in treasuries, ledgers, or FX, with at least 1-2 years in technical leadership or management roles and a proven track record of owning and operating business-critical systems
• Working understanding of crypto wallet architecture (custodial and non-custodial models, key management, address lifecycle, and signing flows) and experience integrating wallet or custody providers in production
• Broad functional fluency across the finance stack: virtual assets, fiat currencies, blockchains, payment networks, ledgers, and partners/counterparties
• Experience building API-driven global financial systems, able to read specs, evaluate integration designs, and write precise API-level requirements
• Deep care for correctness, edge cases, and failure modes; you approach problems methodically, debug with rigor, and prioritize clear, robust solutions over quick fixes
• Deep backend experience and genuine interest in financial infrastructure, working across layers to solve the right problem
• Ability to balance technical depth with product understanding and apply sound judgment to tradeoffs, building systems that are elegant under the hood but practical and adaptable in real-world use
• Clear written communication through design docs, memos, and specs that stand on their own
• High standards for code quality, reliability, and peer review; you value working with others who hold the same bar, communicate clearly, challenge ideas respectfully, and raise the quality of the whole team
• Comfort thriving in high-velocity, ambiguous environments with a roll-up-your-sleeves mentality and ability to run multiple workstreams with competing deadlines
• Strong engineering fundamentals (our main stack is TypeScript, Node.js, NestJS, and AWS, but we value fundamentals over specific toolsets)

Nice to have

• Experience designing systems that are stateless by default, built for scale, and resilient to failure, with comfort in async workflows, distributed services, and cloud infrastructure
• Deeper wallet and custody work such as MPC or HSM-backed signing, multi-chain address management, or running self-custody infrastructure at scale
• Experience supporting B2B and B2C clients with embedded finance infrastructure
• Full-stack experience across backend, frontend, infrastructure, and data
• Experience building or prototyping AI-assisted internal tooling
• Experience working in high-growth teams

What we offer

• Flexible work environment: fully remote for EMEA, hybrid for Hong Kong and Singapore
• Reap Card stipend
• Access to AI tools at work and space to learn, experiment, and grow with them
