Founding Software Engineer (Back-End/Core Systems)

The Role

We’re hiring a Back-End/Core Systems Engineer to design and own the APIs, services, and orchestration logic that power our core systems. You’ll be building the backbone of USDH — from institutional APIs to bridge flows to money movement tracking. You’ll work alongside product, infra, and crypto engineers, and own production-grade services from day one.

• Architect, build, and scale core REST and event-driven APIs used by our partners and internal systems

• Build and maintain database-backed systems for reconciliation, money movement, bridge tracking, and observability

• Implement and evolve systems using tools like PostgreSQL, Redis, Kafka, Clickhouse, Docker, Terraform

• Shape our metrics, logging, and monitoring stack for high-reliability infrastructure

• Collaborate with other engineers to improve our API design, reliability practices, and production tooling

• Contribute to or own cross-chain infrastructure and crypto integrations if you're experienced in that area

• Participate in system design reviews, technical roadmap discussions, and postmortems

• Own code in production — we build with reliability and observability from the start

• 4+ years of experience building production-grade backend systems

• Are highly proficient in TypeScript or Go, and confident working with SQL databases

• Have designed and shipped robust RESTful APIs and backend services with strong uptime and performance guarantees

• Understand and have implemented event-driven systems, including messaging queues and data pipelines

• Have hands-on experience with production infra: Redis, PostgreSQL, Kafka, Docker, Clickhouse, OpenAPI, Protobuf, WebSockets

• Know how to debug, trace, and monitor distributed systems in production environments

• Have worked at a small-to-mid-sized company where you owned critical services, or led backend development for a product line

• Bonus: have crypto-native experience, including Solidity, on-chain infrastructure, bridges, L2s, or trading systems (e.g., MakerDAO, LayerZero, Tenderly, Across, Wintermute, SCP)

• Bonus: experience with financial systems: reconciliation, ledgering, settlement, or audit tooling
