Founding Backend Engineer

THE TEAM & THE ROLE

We are a stealth team building core products for stablecoin and payment rails. Real partners, real revenue signals, and significant ownership upside. Engineers who enjoy solving money-movement problems at scale will thrive here.

Our founding team is building production-grade money infrastructure used by real partners. Research and experimentation are valued, and the immediate focus is on delivering reliable, auditable, and secure systems that move real value. This role offers fast decision cycles, broad scope, and a clear path to leadership and ownership for the right candidate.

WHAT YOU’LL DO

• Design, build, and operate core backend services for stablecoin infrastructure: mint/burn flows, reserve accounting, reconciliation, and settlement pipelines.
• Integrate with banking/payment rails (ACH/wire/SWIFT-equivalents), custody providers, and partner APIs.
• Implement robust reconciliation, observability, and auditing to ensure correctness for high-value flows.
• Own production SLAs: reliability, latency, monitoring, alerting, and runbooks — participate in on-call and incident response.
• Translate ambiguous business and compliance requirements into secure, operational solutions in partnership with product and legal.
• Harden systems against threats: secure API design, secrets management, and formal threat modeling.
• Mentor teammates, influence architecture, and take measurable ownership of product areas with clear equity upside.

SKILLS & QUALIFICATIONS

• 3-7 years building production ready backend systems (Go and Rust preferred)
• Practical experience with payments, banking integrations, or other high-throughput transactional systems
• Strong fundamentals in distributed systems, data consistency, eventing, idempotency, retries, and durable reconciliation.
• Experience designing secure APIs and operational security practices (encryption, access controls, secrets management).
• Comfortable being on-call for money-moving infrastructure and iterating on incident playbooks.
• Clear communicator who can explain tradeoffs to engineering, product, legal, and partner teams.
• Willingness and ability to work in-person in NYC. Relocation supported.

PLUSES

• Direct crypto infra or stablecoin experience (on-chain/off-chain reconciliation, mint/burn flows).
• Experience at payments/fintech companies (Stripe, Plaid, Square, Circle, Paxos, Coinbase, or bank/clearing experience).
• Knowledge of compliance/KYC/AML patterns relevant to custodial or issuance products.
• Experience designing systems for auditable reserves and external attestations.

COMPENSATION & BENEFITS

• $180,000 to $250,000 USD base salary per year
