Original job description

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 Blockchain Engineer at HIFI you will help own on-chain systems day to day. You'll build and maintain the integrations, smart contracts, and wallet infrastructure that connect HIFI's payments products to the chains and stablecoins we support. This is a hands-on role with real ownership: you'll design how funds move and settle on-chain, work with the rest of engineering to connect those flows to our ledger and APIs, and partner with compliance on controls like wallet screening and transaction monitoring. You'll also be the person the team relies on to judge when a new chain or protocol is ready for production use.

What you will build

Wallet infrastructure, including key management, transaction signing, and orchestration across custodial and programmatic wallets.
Onchain transaction handling across EVM chains and the other networks we support, including gas, nonce management, and retries.
Stablecoin minting, burning, and settlement logic that connects USDC and other stablecoins to fiat rails for our on-ramp and off-ramp products.
Integrations with centralized and decentralized exchanges for swaps and liquidity routing, and cross-chain bridging between networks.
A double-entry ledger that keeps onchain balances, banking partners, and customer accounts in sync, with automated reconciliation.
Event listeners, confirmation tracking, and webhooks that give our platform and customers real-time visibility into onchain activity.
Idempotent transaction pipelines with failure recovery and screening hooks, so money moves correctly even when something goes wrong.

You might be a fit if

3+ years of software engineering experience, including at least 1 to 2 years building blockchain systems in production.
Deep familiarity with EVM chains, including transaction lifecycles, gas mechanics, common failure modes, and enough Solidity to read and integrate contracts.
Experience with wallet architecture, such as custody models, signing services, or MPC and HSM-backed setups.
Strong backend fundamentals, including API design, data modeling, and handling consistency and concurrency in distributed systems.
You build financial systems with reconciliation and audit trails by default.
You communicate clearly in code review and in writing.

Nice to have

Experience with stablecoin infrastructure such as Circle, or with connecting onchain and fiat settlement.
Hands-on work with CEX APIs, DEX protocols like Uniswap, or bridge integrations.
Experience building ledgers or double-entry accounting systems.
Exposure to compliance engineering, such as transaction monitoring, address screening, or Travel Rule tooling.
Experience with non-EVM chains like Solana or Tron.
Familiarity with traditional money movement, including ACH, wires, and how funds settle between banks and processors.
Early-stage startup experience building and running a system from scratch.

Why This Role Matters

Every payment HIFI processes eventually settles on-chain, and the institutions behind those payments expect them to work as reliably as a wire or an ACH transfer. This is a chance to build the on-chain systems that hold stablecoin payments to that standard, and to shape how regulated money moves on public blockchains while that infrastructure is still being defined.

Additional Requirement

Must be within a commutable distance from our office and able to work in person most days of the week.

Equal Opportunity Statement

HIFI is an equal opportunity employer. We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other legally protected status. We also provide reasonable accommodations during the hiring process.
