Senior Software Engineer - Integrations

Responsibilities

• Own the design and implementation of major integrations and subsystems, from initial partner evaluation through production rollout and ongoing operation
• Build and maintain integrations with third-party data providers (KYB, KYC/IDV, AML, fraud, banking, identity) and abstract them behind clean, versioned internal contracts
• Design, evolve, and operate Worth's public REST APIs and SDKs, with strong attention to versioning, backward compatibility, authentication, rate limiting, and developer experience
• Break down ambiguous partner specs, customer integration requirements, and vendor edge cases into clear technical designs with well-understood tradeoffs
• Write high-quality production code across backend and (where needed) frontend systems using Node.js, TypeScript, Nest.js, and React.js
• Design and evolve PostgreSQL schemas that capture vendor responses, normalization layers, and crosswalking metadata, with strong attention to indexing, performance, and data integrity
• Build event-driven workflows with Kafka and Redis that orchestrate enrichment, retries, dead-lettering, and backpressure across slow or flaky upstream APIs
• Optimize slow queries and resolve systemic performance bottlenecks in high-throughput integration pipelines
• Deploy, monitor, and debug containerized integration services in Kubernetes, including the alerting and runbooks that catch vendor degradations before customers do
• Lead pragmatic refactors of legacy or accreted integration code into modular, testable, swappable adapters
• Communicate complex tradeoffs across engineering, product, partnerships, and customer-facing teams

Requirements

• 8+ years of professional software engineering experience
• Demonstrated ownership of major features or subsystems in production, ideally with significant integration or platform-API surface area
• Deep expertise in the Node.js and TypeScript ecosystem
• Strong system design skills, especially around resilient integrations: retries, idempotency, circuit breakers, rate limiting, webhook handling, and graceful degradation
• Experience designing or operating a public API or SDK (versioning, auth, contracts, developer ergonomics)
• Hands-on experience with PostgreSQL, including schema design and query optimization
• Experience building or maintaining event-driven systems using Kafka
• Comfort operating containerized applications in Kubernetes
• Proven ability to refactor complex or legacy integration code into modular, swappable, well-tested adapters
• Proven experience mentoring junior engineers and raising team quality standards
• Ability to operate effectively in high-ambiguity environments, including partner specs that are incomplete, contradictory, or change underneath you
