Senior Software Engineer - Integrations

Responsibilities

• Own the design and implementation of major integrations and subsystems from partner evaluation through production rollout and ongoing operation.
• Build and maintain integrations with third-party data providers for KYB, KYC/IDV, AML, fraud, banking, and identity, abstracting them behind clean, versioned internal contracts.
• Design, evolve, and operate public REST APIs and SDKs with attention to versioning, backward compatibility, authentication, rate limiting, and developer experience.
• Translate ambiguous partner specifications, customer integration requirements, and vendor edge cases into clear technical designs.
• Write production code across backend and, when needed, frontend systems.
• Design PostgreSQL schemas and optimize queries for performance and data integrity.
• Build event-driven workflows that orchestrate enrichment, retries, dead-lettering, and backpressure across upstream APIs.
• Deploy, monitor, and debug containerized integration services in Kubernetes, including alerting and runbooks.
• Refactor legacy integration code into modular, testable, swappable adapters.
• Handle production incidents and harden systems against vendor outages, schema changes, authentication rotations, and quota exhaustion.
• Lead code reviews and coach engineers on integration patterns, resilience, testing strategy, and API design.
• Communicate technical tradeoffs across engineering, product, partnerships, and customer-facing teams.

Requirements

• 8+ years of professional software engineering experience.
• Ownership of major production features or subsystems, ideally involving integrations or platform APIs.
• Deep expertise in Node.js and TypeScript.
• Strong system design skills, including retries, idempotency, circuit breakers, rate limiting, webhook handling, and graceful degradation.
• Experience designing or operating public APIs or SDKs, including versioning, authentication, contracts, and developer ergonomics.
• Hands-on PostgreSQL experience, including schema design and query optimization.
• Experience building or maintaining event-driven systems with Kafka.
• Experience operating containerized applications in Kubernetes.
• Ability to refactor complex integration code into modular, swappable, well-tested adapters.
• Experience mentoring junior engineers and raising team quality standards.
• Ability to work effectively in high-ambiguity environments.

Success Metrics

• New vendor and customer integrations ship reliably and on schedule with rollout, monitoring, and rollback plans.
• Existing integrations meet performance and reliability targets.
• The public API remains consistent, versioned, and easy for customers to use.
• Code quality and maintainability improve across the integration layer.
• Squad delivery velocity improves through clearer technical direction and stronger execution.
