Job description

Chief of Staff @ HIFI I Stanford GSB MBA (Class of 2025) I Stablecoin

About the Company

HIFI is a financial infrastructure platform for the modern internet. Businesses around the world—from fast-growing fintech startups to global financial institutions—use HIFI to move money across stablecoins, fiat rails, and onchain systems through a single programmable interface. Our customers use HIFI to automate payments, orchestrate treasury, power embedded finance products, and launch new global money workflows without needing to build or manage complex banking, blockchain, or compliance infrastructure themselves. Our mission is to make money programmable by default, and to give developers and businesses the tools to move value instantly, globally, and with software-level control.

About the Team

The HIFI platform team builds the infrastructure, developer experiences, and financial workflows that power stablecoin-native finance at scale. The team designs and maintains the APIs, user-facing tools, and partner integrations that allow customers to create accounts, move money across bank and blockchain rails, and operate compliant global payment systems. We work across the full lifecycle of modern money movement—from account creation and ledgering, to fiat and stablecoin settlement, to global payouts and onchain connectivity. Our customers span fintech platforms, marketplaces, exchanges, neobanks, payroll providers, and tokenized asset platforms operating across the U.S., Europe, Africa, LatAm, and MENA. This is an opportunity to help build one of the fastest-growing segments of financial infrastructure and define how money moves on the internet over the next decade.

About the Role

We’re looking for a Backend Engineer to help build the critical systems that power HIFI’s global stablecoin payment infrastructure. You’ll work on our APIs, ledgering and settlement services, developer tooling, and the core transaction logic that moves money instantly and securely across bank networks and blockchains. You’ll collaborate closely with product, compliance, and frontend teams to enable seamless experiences for enterprise developers. This is an opportunity to shape foundational services that support billions in global transaction volume. This role is based in-person in New York, working closely with our small and fast-moving engineering team.

Responsibilities

• Core Infrastructure Engineering
• Architect, implement, and evolve backend services that power real-time bank-to-stablecoin settlement and ledger operations
• Build scalable, resilient microservices and APIs handling high-volume financial transactions
• Develop robust data models, transaction orchestration logic, and state-management systems
• Own services end-to-end: deployment pipelines, observability, and operational excellence
• Performance, Reliability & Security
• Design for high-throughput, low-latency execution across distributed environments
• Implement advanced monitoring, automated rollback strategies, and fault‑tolerant failover
• Apply best practices in secure system design, encryption, and identity-aware workflows
• Continuously tune compute, storage, and networking to maintain strict SLAs
• Work closely with product, compliance, and cross‑functional engineering teams to deliver enterprise‑grade capabilities
• Translate financial, regulatory, and settlement requirements into scalable backend logic
• Participate in architectural reviews and shape standards for backend systems
• Infrastructure for Global Scale
• Contribute to infrastructure capable of supporting billions in global transaction volume
• Extend corridor capabilities across new chains, bank partners, and payment networks
• Ensure systems adapt seamlessly to increased demand and evolving regulatory environments

Qualifications

• 3+ years building and maintaining production backend systems
• Strong proficiency in modern backend languages (e.g., Go, TypeScript/Node.js, Python, or Java)
• Experience with RESTful services, APIs, distributed systems, and relational databases (Postgres/MySQL)
• Familiarity with event‑driven architectures, queues/streaming (Kafka, Pub/Sub, SQS, etc.)
• Understanding of how backend systems interface with security, identity, and risk controls
• Good product instincts. You think about user outcomes, not just implementation details
• Experience delivering production features in fast‑paced, high‑ownership environments

Preferred Skills

• Experience in payments, fintech, banking, liquidity or settlement systems
• Exposure to AML/KYC compliance workflows, identity services, or financial transaction monitoring
• Familiarity with security fundamentals for financial systems, such as encryption, key management, tokenization, and fintech application security best practices
• Prior startup experience or comfort operating in ambiguous, high‑growth conditions
