About the role
Key responsibilities & impact- Own the end-to-end technical integration between Reap and the partner — including design, implementation, testing, deployment, and ongoing maintenance
- Build and operate bidirectional data flows: inbound (partner → Reap: funding, settlement, account events) and outbound (Reap → partner: card events, transaction data, reconciliation signals)
- Serve as Reap's primary technical point of contact with the partner's engineering team — attending syncs, reviewing their API specs, and driving alignment on integration contracts
- Translate the partner's technical requirements and constraints into well-scoped engineering work inside Reap's systems
- Collaborate closely with internal Reap teams — Card, Treasury, Onboarding, Compliance — to ensure integration requirements are correctly surfaced and delivered
- Monitor integration health in production; own incident response for integration-layer issues
- Maintain thorough integration documentation: API contracts, data flow diagrams, runbooks, and change logs
- Design robust, fault-tolerant bidirectional integration architecture between Reap and our partner
- Implement APIs, webhooks, event consumers, and data transformation layers
- Ensure data consistency, idempotency, and auditability across integration boundaries
- Build test suites covering integration contracts and edge cases
- Maintain a close working relationship with partner's engineering and product teams
- Drive joint technical decision-making on integration patterns, versioning, and deprecation
- Proactively surface blockers and misalignments before they become production issues
- Work with Card, Treasury, Onboarding, and Compliance engineers to deliver integration dependencies
- Represent the integration workstream in Reap engineering planning and reviews
- Own observability for the integration layer: dashboards, alerting, and SLA tracking
- Lead incident response and post-mortem processes for integration-related issues
- Continuously improve integration stability and reduce operational toil
Requirements
What you’ll need- 6+ years of backend software engineering experience
- Proven experience building and operating production-grade API integrations with external partners or third-party systems
- Strong understanding of integration patterns: REST APIs, webhooks, event-driven architecture, idempotency, retry logic, and error handling
- Experience working across organisational boundaries — with partner or client engineering teams
- Comfortable operating in ambiguity: translating loosely defined requirements into concrete engineering solutions
- Clear written and verbal communication; able to represent technical decisions to both engineering and business stakeholders
Benefits
Comp & perks- High-ownership, high-impact role at the frontier of stablecoin-powered finance
- Work directly with strategic partners and shape how Reap expands its financial ecosystem
- Operate with significant autonomy as Reap's technical owner of a key partnership
- Join a high-caliber team across engineering, product, and operations
- Insurance coverage after probation
- Reap Card stipend
- Use of AI tools at work — and the space to learn, experiment, and grow with them
- A culture of innovation, inclusion, and continuous learning
