Provides senior-level engineering leadership and hands-on software development for the applications that automate, deploy, administer and monitor Liberty Mutual's global network fabric. This role sits at the intersection of infrastructure, networking and software engineering: while grounded in networking fundamentals, it is primarily a senior software and application development and data management role in support of infrastructure-as-code (IaC) efforts.

The Solutions Engineer is a principal contributor to the Network Automation and Rapid Response System (NARRS) — the internally hosted platform leveraged by multiple internal networking teams to deploy and administer Dell SONiC, Cisco ACI, and Arista network components across the global network landscape. NARRS delivers administrative and deployment capabilities along with health and error metrics/observability. Working within Agile delivery teams, the role is responsible for designing, advancing, enhancing and supporting these applications — ensuring they are secure, reliable and observable because they support core network fabric environments.

As a senior engineer, this individual sets the technical bar for code quality, security, and automation across the team.

1. Acts as a senior/lead solution engineer and technical lead for the design, development, enhancement and support of the internally hosted network deployment and administration applications, aligning implementation with technical architecture, customer business plans and long-term strategy.

2. Designs and builds full-stack applications and services using Python, Java, JavaScript, Node.js, React and Kubernetes, applying infrastructure-as-code practices to automate the deployment, administration and lifecycle management of network components.

3. Works within Agile methodologies as part of cross-functional delivery teams — participating in sprint planning, backlog refinement, reviews and retrospectives — and drives continuous improvement in team velocity and product/team performance.

4. Manages source control, branching, and CI/CD workflows in Git Hub, championing automated build, test, deployment and management processes to increase delivery speed, consistency and reliability.

5. Performs security reviews and peer code reviews of planned code deployments, enforcing engineering standards, secure coding practices, and maintainability before changes are promoted to network fabric environments.

6. Incorporates AI fundamentals — including AI-assisted development tooling and applied machine learning / intelligent automation — to advance automation, anomaly detection, and operational efficiency within the applications.

7. Develops and enhances open network / open-source deployment and administration capabilities supporting Dell SONiC, Cisco ACI and Arista environments across the global network.

8. Builds and maintains observability into the applications (performance, health and error metrics, logging, telemetry, alerting) so networking teams have clear, actionable visibility into deployment status and fabric health.

9. Embeds strong network and application security fundamentals into the software development lifecycle, recognizing that these applications support core network fabric environments; manages troubleshooting and resolution of…
