OVERVIEW

We are seeking a Lead Software Engineer (Backend / Integrations) to anchor the backend workstream of a contractor program supporting a critical customer engagement: a state government professional licensing and regulatory compliance platform built on Google Cloud. This is a hands-on technical leadership role. The successful candidate owns the architecture of the core platform services and the external integration layer, sets the engineering standards the backend team works to, and remains in the codebase day to day. They will work closely with the client technical lead, the mobile and frontend engineers, and customer stakeholders to ensure project success from initial definition through final delivery.

Expected start date: 5 October 2026.

REQUIRED QUALIFICATIONS

Java 21 and Spring Boot 3.x microservice development

Service and API design across a multi-service platform, including contract and versioning strategy

PostgreSQL, including schema design, indexing, and versioned migrations

GCP serverless services: Cloud Run, Pub/Sub, Cloud Tasks, Cloud Workflows, Cloud Scheduler

Event-driven architecture and messaging patterns (idempotency, retries, dead-letter handling)

External system integration over REST, SOAP, SFTP, and webhooks

API security with OAuth 2.0 / OIDC and JWT

Automated testing (JUnit, integration tests), CI/CD, and the quality standards that govern them

Prior experience leading a distributed or contractor engineering team

SCOPE AND SOLUTION EXPECTATIONS

Below covers the scope of work we anticipate the contractor supporting throughout the project timeline.

Design and implement Java 21 / Spring Boot microservices on Cloud Run (licensing, case management, payments, documents, notifications)

Implement PostgreSQL (AlloyDB) persistence, including row-level data isolation and search indexing

Build asynchronous event flows on Pub/Sub and Eventarc

Implement scheduled and timer-driven processing with Cloud Tasks and Cloud Scheduler (renewal reminders, expiration sweeps, reconciliation)

Author Cloud Workflows orchestrations for multi-service pipelines

Direct the build-out of integrations with external state and federal systems over REST, SOAP, SFTP, and webhooks

Oversee payment flows, including hosted payment page integration and settlement reconciliation

Own platform security and compliance outcomes for encryption and data isolation
