About HIFI

HIFI is a stablecoin infrastructure company building technology for the next-generation of financial products. We build tools for payments and tokenized money products across money movement, cards, and capital markets. Institutions and enterprises already use our platform and APIs to move billions of dollars in production environments around the world, and we are still early.

Founded in 2022, our organization is flat and our team is talent dense. We work in person at our office in Flatiron and are intentional about who we work with. We've raised $37 million from world-class investors, including a Series A led by Left Lane Capital.

About the Team

HIFI's engineering team builds the payments infrastructure that fintechs and financial institutions use to move money on stablecoin rails. The team owns the APIs, ledger, and on-chain systems behind every payment HIFI processes, and works closely with product and compliance to make sure that infrastructure is reliable, secure, and ready for regulated use. As HIFI's volume grows and more institutions build on our platform, this team will decide how stablecoin payments hold up at the scale and standard that traditional financial infrastructure is held to.

As a Security Engineer at HIFI you will help own the security of our company and the infrastructure behind our payments products day to day. You'll build HIFI's security program from the ground up, including identity and access management, endpoint security, and the cloud and network controls that protect our systems and data. This is a hands-on role with real ownership: you'll set the security roadmap based on risk, put core capabilities like monitoring, incident response, and secrets management in place, and write the policies that govern how HIFI handles access and information. You'll also be the person the team relies on to keep HIFI ready for audits and partner security reviews as we expand into more regulated markets.

What you will build

• Design and implement the HIFI security roadmap from first principles to production, prioritizing by risk.
• Lead threat modeling and hardening for our money movement systems.
• Build core security capabilities, including monitoring and detection, incident response, secrets management, API security, and CI/CD hardening.
• Own cloud and network security architecture, including segmentation, encryption, and least-privilege access.
• Own endpoint and identity security across our devices and SaaS tools.
• Reinforce engineering best practices around secure development and infrastructure.
