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
Senior Frontend Engineer

This role is based in-person in New York, working closely with our engineering and GTM teams.
We value people who:
Find large challenges exciting and enjoy discovering and defining problems as much as solving them
Deliver — you may enjoy thoughtful conversations and perfecting designs, but in the end, you care about building reliable solutions that ship
Communicate clearly and comfortably across teams, asking questions, sharing ideas, and speaking up
Learn quickly, stay curious, and adapt to new challenges with a growth mindset
Move fast and stay effective in ambiguous, evolving environments, with a strong sense of urgency to get things done
Give and receive feedback openly, and collaborate across functions
Bring passion and experience — for Web3, modern payment solutions, or anything else — and channel it into their work

Technical Leadership
Drive architecture decisions for frontend systems to maximize performance, resiliency, and maintainability.
Build fast, reliable build pipelines optimizing developer velocity.
Design comprehensive testing frameworks and monitoring to guarantee uptime and reliability.
Champion continuous performance tuning, technical debt reduction, and security improvements.
Partner with engineering, product, and GTM leads to define product requirements and developer journeys.
Influence product roadmap and advocate for developer needs.
Exercise strong product judgment. Prioritizing simplicity and clarity in developer tools.
Systems & Scale
Ensure frontend systems are capable of supporting global usage and billions in transaction volume.
Design integration frameworks and SDKs that enable seamless API adoption.
Proactively anticipate future product needs and scalability requirements.
Team Contribution
Mentor and support junior/mid-level engineers across the frontend stack.
Contribute to hiring, onboarding, and growing frontend engineering culture.
