Onramp is an American bitcoin platform offering brokerage, custody, bitcoin IRA, BTC-backed loans, and other financial services for individuals and institutional clients.
We're building the money platform of the future for individuals, businesses, and financial institutions — Bitcoin, dollars, and stablecoins in one place, secured by multi-institution custody and delivered through products people love and APIs institutions build on.
Responsibilities
Own platform architecture across API re-platforming, custody infrastructure, money movement rails, and the mobile/web clients that sit on top
Own security architecture across custody infrastructure and money-movement rails — threat modeling, secure-by-design review, key-management security, and incident response — as the technical security voice partnering with compliance
Own and continuously improve our cybersecurity program — the security tooling, processes, and procedures we already run — maturing them as we scale and keeping them right-sized for a company our size, in lockstep with our SOC 2 program
Write code most days — the hard parts: core services, API design, integrations with custodians, banks, and stablecoin rails
Turn tribal knowledge into written architecture docs, runbooks, and decision records
Mentor a talented, hungry team and raise the quality bar through review and example, not process for its own sake
Build and evangelize AI-native workflows — agent orchestration, multi-model code review, automated testing and documentation
Partner directly with product, sales, and our banking and custody partners
Requirements
A senior, staff, or principal-level engineer (or a hands-on VP/Head of Engineering who misses the keyboard) with deep experience building production financial systems, APIs, or platform infrastructure
A proven security leader who has owned security architecture or secure-by-design for financial, custody, or other high-stakes systems, and can set and hold the security bar for the team
Has owned and leveled up a security program at an early- or growth-stage company — sharpening the tooling and processes that already exist without adding enterprise bloat
Insanely AI-native — you orchestrate agents, run multi-model workflows, and have strong, current opinions on tooling because you use it every day
An architect who ships — comfortable owning system design and the pull requests that implement it
A force multiplier who has led through influence, mentorship, and code
Fluent, or aggressively curious, in the money stack: Bitcoin, custody, key management, stablecoins, payment rails, brokerage, ledgering — with real depth on the security side of it
A clear written communicator — architecture docs, decision records, and async updates that people actually read
Comfortable with the ambiguity and pace of an early-stage company where the roadmap is won, not given
Nice to Have
Experience with banking/fintech integrations (KYC, ledgering, ACH/wires, stablecoin issuance), React/React Native and modern backend stacks, mobile product experience, security or compliance program work (SOC 2), or prior early-stage leadership.
