Senior Integration Engineer

Every customer interaction in our contact center depends on a web of systems talking to each other quickly and correctly: Monumint, uContact, our Loan Management System (LMS), internal services, and third-party APIs. We're hiring a senior engineer to build and run that layer: real-time integrations that move customer and account data reliably at volume, built on an event-driven core.

This is a hands-on build role. You'll ship production code every week, and you'll do it the way modern teams do: directing a fleet of AI development agents, reviewing and verifying their output, and delivering far more than one engineer working alone.

Primary Duties and Responsibilities:

• Design and build integrations across Monumint, uContact, the LMS, internal applications, and third-party services using Kafka event streams, REST APIs, and webhooks.

• Build on our event-driven architecture, which sits at the center of everything in this role: producers and consumers, topic and schema design, idempotency, ordering, retries, dead-letter handling, and backpressure.

• Build Node/TypeScript services in NestJS, run as containerized workloads on GCP and backed by Postgres.

• Build MCP servers that give AI agents and AI-powered engagement platforms safe, well-scoped access to our systems and data.

• Turn workflow improvements from Contact Center Automation & Systems into production implementations, such as call routing driven by real-time account status.

• Make integrations observable (logging, metrics, tracing, alerting) and own their production health, from incident response to root-cause fixes.

• Secure every interface (OAuth 2.0, JWT, API keys, secrets management) and assess vendor APIs for feasibility and fit.

• Keep architecture, API contracts, and data mappings documented and current.

Professional Qualifications Requirements:

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements that follow are representative of knowledge, skills and/or abilities required.

Education

Work Experience

• Significant software engineering experience (typically 6+ years), much of it building and operating integrations.

• Strong Node.js and TypeScript.

• Production experience with NestJS or a comparable modern API framework; NestJS strongly preferred.

• GCP and containerized workloads (Docker plus GKE or Cloud Run), with CI/CD.

• Postgres: schema design, query performance, and transactional patterns such as the outbox pattern.

• Experience building MCP (Model Context Protocol) servers.

• Clear communication with operations and business stakeholders, not just engineers.

Knowledge and Skills

• High-throughput integrations for business-critical applications. A proven record building systems where downtime or lost data has a real cost.

• Deep familiarity with event-driven architecture and Kafka in production. Nearly everything you build here will have EDA at its core.

• AI-native development. You work with coding agents daily, run several in parallel, and know how to scope their tasks and verify what they produce.
