Lead Software Engineer - Backend Engineering (Core) / Integrations

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 CREDENTIALS

• 10+ years of professional backend engineering experience with Java and Spring Boot

• Demonstrated technical leadership of a backend team or workstream — setting architecture, reviewing code, and mentoring engineers — while still contributing production code

• Production delivery experience on Google Cloud Platform, with ownership of a system through design, launch, and operation

• Bachelor's degree in Computer Science or equivalent practical experience

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

• Working directly with non-engineering stakeholders to turn requirements into a delivery plan

USEFUL QUALIFICATIONS

• Workflow engines (Flowable, BPMN) and business rules engines

• AlloyDB, BigQuery

• Payment processing integrations

• Experience in government or regulated environments (FIPS, CJIS, HIPAA)

• Google Cloud Professional certifications

• 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.

• Own the backend architecture: service boundaries, data model, event contracts, and the integration layer design

• 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

• Set and enforce test coverage, code review, and CI/CD standards across the backend team

• Break down the backend scope, sequence the work, and report delivery status to the client technical lead and customer stakeholders

• Mentor engineers on the team and support technical onboarding of new contractors
