The successful candidate will play a critical role in building the backbone of the platform. They will design smart, scalable backend systems that power complex integrations with government and enterprise partners, eliminate manual operational work, and set the team up to move faster with less friction. The initial focus will be on the most technically demanding integration: a bidirectional sync system that requires sophisticated error handling, async workflows, and operational automation. The engineer will build the infrastructure and patterns that not only solve this specific challenge but become the foundation for how the company approaches integration reliability and operational excellence platform-wide. It is a hands-on, high-impact role where the candidate will see immediate results — fewer production issues, faster support resolution, and systems that scale confidently — while building expertise that positions them to drive platform initiatives across the growing infrastructure.

Requirements

Strong backend development experience with TypeScript/Node.js and modern AWS services (Lambda, EventBridge, SQS)
Deep understanding of distributed systems patterns: idempotency, retries, eventual consistency, and error handling
Experience building and maintaining integrations with third-party APIs
Proficiency with at least one database technology (SQL or NoSQL) for production systems
Strong debugging and troubleshooting skills using logs, metrics, and tracing
5–8+ years in backend, platform, or integration engineering roles with focus on building reliable systems for complex external integrations
Built and maintained bidirectional sync systems between internal platforms and third-party APIs, handling edge cases like duplicate records, missing data dependencies, and validation failures
Designed and implemented event-driven architectures using serverless technologies (Lambda, Step Functions) for async workflows at scale
Integrated with legacy or government systems where API documentation is incomplete and error handling must be defensive
Worked extensively with both SQL and NoSQL databases — using document databases for state management and SQL for data validation and analytics
Built operational automation and internal tools that reduced manual support work, enabling non-technical teams to self-serve and resolve issues
Implemented comprehensive observability for integration pipelines: structured logging, metrics, distributed tracing, and alerting for proactive issue detection
Worked in environments with strict SLAs, compliance requirements, or high operational load where reliability and correctness are non-negotiable
Collaborated with customer support and success teams to understand pain points, prioritize fixes, and build solutions that reduce escalations
Experience with multi-tenant architectures and tenant-specific configurations

GraphQL API design and implementation
MongoDB or DynamoDB for managing async workflows and state machines
SQL/data warehouse experience for validation and analytics (Redshift, PostgreSQL)
Experience with government APIs, legacy enterprise systems, or partners with limited documentation
Event-driven architecture at scale using serverless patterns
CloudWatch Logs Insights, New Relic, or similar observability platforms
Multi-tenant architecture and tenant-specific configuration managements
