Senior Software Engineer - Integrations

Orlando, FLBackend EngineeringRemote8+ YOE
Summary

Senior Software Engineer owning integrations with third-party providers, public APIs/SDKs, event-driven systems, and Kubernetes services. Requires 8+ years experience, deep Node.js/TypeScript expertise, and strong system design for resilient integrations.

About the role

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.
  • Handle production incidents methodically (vendor outages, schema changes, auth rotations, quota exhaustion) and harden the system to reduce recurrence.
  • Lead by example in code reviews, coaching others on integration patterns, resilience, testing strategy, and API design.
  • 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.
  • Demonstrated 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.

Nice-to-Haves

  • Direct experience integrating with KYB, KYC/IDV, AML, fraud, banking, or identity data providers.
  • Experience building and shipping a public SDK in one or more languages.
  • Experience with AWS services including MSK, RDS, EKS, S3, and Lambda.
  • Experience with Infrastructure-as-Code tools such as Terraform.
  • Strong background in distributed caching strategies using Redis (response caching, dedup, rate limiting).
  • Experience with Redshift schema design and ETL pipelines for vendor data.
  • Production experience with Python in backend systems.
  • Background in fintech, payments, lending, or regulated data environments.
