About the CMS Registry Solution

The CMS Registry Solution powers end-to-end collateral and lien management for banks, automotive finance companies, credit unions and other lenders. The platform automates the full lien lifecycle-registration, amendment, search, monitoring and discharge-to protecting lenders, reduce risk and ensure compliance, and provides value-added features such as lien validation, asset monitoring and fraud detection.

We're actively modernizing the platform that is mission-critical used by major financial institutions with a focus on scalability, automation, and developer experience. Current work includes containerizing services, upgrading .NET runtimes, strengthening CI/CD and observability, and adopting Infrastructure as Code-alongside pragmatic AI-assisted development and intelligent QA.

You'll join a small, critical, high-impact support team (engineers, product owner, engineering manager) focused on keeping customer-facing systems reliable and resolving real production issues. You'll own the operational health of key parts of the platform, contribute to incident response and reliability improvements, and help raise the quality bar through strong troubleshooting, documentation, and engineering judgment.

The Software Engineer - Support is an individual contributor responsible for maintaining the reliability, stability, and operational health of CMS services. This role focuses on hands-on execution within a single team or service area, supporting production systems and contributing to continuous operational improvement.

The role works across the full stack - Angular frontends, .NET (Core / 6+ / .NET 8) services, and SQL Server - and delivers KTLO / BAU outcomes including incident response, production troubleshooting, runbook maintenance, release and patch support, and reliability improvements under guidance.

The engineer collaborates closely with Product, Development, Platform, and Database teams to help ensure service availability, meet SLAs, and support safe change delivery.

What You'll Do: 

Incident Management & Operations

• Support the reliability and operational health of current EC2-hosted services while assisting with incident response, monitoring, and KTLO operations during the migration to containerized deployments
• Participate in production incident response by triaging issues and contributing to resolution in line with defined SLAs
• Participate in an on-call rotation, following established escalation paths and providing after-hours support as required
• Communicate incident status and updates clearly to technical stakeholders

• Monitor application and infrastructure health using tools such as New Relic, SolarWinds DPA, CloudWatch, or Datadog
• Proactively tune alerts and act on early warning signals to prevent customer impact
• Diagnose complex production issues using logs, traces, metrics, and user reports
• Apply mitigations and deliver permanent fixes in collaboration with development teams

KTLO / BAU Ownership

• Maintain and update runbooks, playbooks, FAQs, and troubleshooting documentation
• Perform KTLO activities such as scheduled maintenance, patching, backups and restores, database indexing, archiving jobs, and capacity checks
• Support releases, hotfixes, and patches, including deployment validation and production smoke testing

Continuous Improvement

• Contribute to root cause analysis (RCA) for production incidents
• Identify recurring issues and suggest operational or automation improvements
• Assist with performance investigations, including SQL query analysis, under guidance
• Adopt automation and AI-assisted tooling to reduce operational toil and improve triage efficiency

What We're Looking For:

Must Have

• Hands-on experience with .NET and C#, including modern .NET runtimes, for production support and fixes
• Familiarity with AWS services such as EC2, S3, CloudWatch, and IAM
• Exposure to CI/CD pipelines (GitHub Actions preferred), including release support and troubleshooting
• A DevOps mindset with interest in build, deploy, operate, and improve workflows
• Working knowledge of Angular, TypeScript, and RESTful APIs, with the ability to debug issues across the stack
• Experience supporting SQL Server-based applications, including basic performance analysis and operational tasks (AWS RDS experience a plus)
• Comfort working in production environments and responding to incidents
• Interest in using AI-assisted development and intelligent QA tools to improve productivity
• Strong collaboration, communication, and ownership mindset

Nice-To-Have

• Experience with Docker and containerized applications
• Exposure to Infrastructure as Code (Terraform or CloudFormation)
• Familiarity with modern test automation tools (e.g., Playwright, Cypress)
• Prior experience in L2/L3 production support or on-call rotations

Impact You'll Deliver:

By joining the Support team, you'll help keep the CMS platform stable and trusted by contributing to faster incident resolution, safer releases, improved operational documentation, and the organization's transition toward more cloud-native and automated operations.
