Full Job Description

📋 Description

• Design and ship backend services that handle stablecoin issuance, custodial wallet operations, and global asset conversion workflows with high reliability and security.
• Work within one of four product verticals: Custody, On/Off Ramps, Issuance, or Shared Services, collaborating directly with product managers, compliance teams, and fellow engineers.
• Ship small feature slices or quality-of-life improvements within the first 30 days, ensuring safe production deploys with follow-up verification.
• Ramp up on service architecture, CI/CD pipelines, observability tooling (Datadog, Grafana, Sentry), and engineering conventions across the codebase.
• Add tests, dashboards, and runbook documentation to improve maintainability and onboarding for your assigned service areas.
• Take ownership of a service or capability by 90 days, leading medium-scope projects such as API contract updates, partner integrations, or reliability improvements.
• Strengthen system reliability through enhanced logging, tracing, alerts, and failure handling mechanisms for critical financial workflows.
• Drive cross-service initiatives by 180 days, such as API versioning plans, data model migrations, or compliance-driven workflow changes.
• Shape technical direction through design docs, mentoring junior engineers, and partnering with product and compliance to make regulation-aware tradeoffs.
• Design stable, evolvable APIs for custody, transfers, or issuance that avoid breaking downstream clients.
• Build idempotent job flows for high-throughput asset transfers with strong audit trails and tamper-resistant logging.
• Harden key operations using hardware-backed isolation (Nitro Enclaves) and robust cryptographic key policies.
• Improve p95 latency through query optimization, caching strategies, or backpressure implementation in high-volume financial systems.
• Navigate tradeoffs between product velocity and regulatory compliance requirements in a licensed financial infrastructure environment.
• Integrate services with banking partners and crypto infrastructure providers using secure, standardized protocols.
• Work in a hybrid-but-flexible model based in New York City—come into the office when effective, with no set days required.
• Contribute to a remote-first, async-by-default engineering culture where initiative, ownership, and impact are expected.
• Deploy services using AWS, Kubernetes, Terraform, and containerized environments with infrastructure-as-code practices.
• Use Go and TypeScript/Node.js as primary languages; some services leverage Rust; gRPC and REST for internal services, GraphQL/tRPC at the edge.
• Manage data and async processing with Postgres, Redis, and Kafka; coordinate workflows using Temporal.
• Participate in incident response using Incident.io and maintain operational readiness through proactive observability.

🎯 Requirements

• Proven experience building and maintaining production-grade backend services in a regulated financial or high-stakes environment
• Proficiency in Go and TypeScript/Node.js; experience with Rust is a plus
• Hands-on experience with gRPC, REST, and API design for distributed systems
• Experience with AWS, Kubernetes, Terraform, and containerized deployments
• Demonstrated ability to work with Postgres, Redis, Kafka, and Temporal for data and async workflows
• Strong understanding of observability tooling (Datadog, Grafana, Sentry) and incident response practices

🏖️ Benefits

• Hybrid-but-flexible work model based in New York City with no required office days
• Remote-friendly environment open to remote candidates
• Ownership of critical financial infrastructure with direct impact on customers and partners
• Opportunity to shape technical direction through design docs and mentoring
• Equal employment opportunity employer with non-discrimination policy covering all protected characteristics
• Participation in E-Verify for U.S. employment eligibility
