The successful candidate will bring deep technical expertise in PowerShell, .NET applications, AWS cloud infrastructure, New Relic, and Splunk, combined with a strong understanding of Site Reliability Engineering principles and modern operational practices.
As a senior technical contributor, you will play a critical role in advancing Zelis's enterprise reliability strategy by improving application performance, strengthening observability, automating operational processes, and partnering with engineering teams to design and maintain highly available, resilient systems.
We are looking for an engineer who goes beyond monitoring systems and responding to incidents - someone who understands how applications work, can diagnose complex technical issues, identifies opportunities for automation, and proactively engineers solutions that prevent incidents before they occur.
This position requires a combination of software engineering expertise, production operations experience, cloud engineering knowledge, and technical leadership.
- Champion Site Reliability Engineering principles and best practices across the Zelis technology organization.
- Establish and improve Service Level Indicators (SLIs), Service Level Objectives (SLOs), and reliability measurements.
- Identify systemic reliability risks and develop engineering solutions to eliminate recurring operational issues.
- Reduce manual operational toil through automation, self-healing capabilities, and improved engineering practices.
- Collaborate with application development, infrastructure, cloud engineering, and security teams to improve production readiness.
- Drive continuous improvement through measurable reliability, performance, and operational efficiency outcomes.
- Design, develop, and maintain advanced PowerShell scripts, automation frameworks, and operational tooling.
- Troubleshoot and optimize enterprise applications built on Microsoft .NET and C# technologies.
- Analyze application behavior, dependencies, configuration, and performance to identify underlying technical issues.
- Partner with software engineering teams to improve application reliability, error handling, logging, and operational supportability.
- Develop reusable automation and engineering solutions that reduce repetitive manual intervention.
- Integrate automation into CI/CD pipelines and operational workflows.
- Serve as a technical subject matter expert in New Relic and Splunk, driving effective implementation and adoption of observability practices.
- Design and improve application performance monitoring (APM), infrastructure monitoring, distributed tracing, logging, and alerting.
- Develop meaningful dashboards, alerts, and service health indicators that provide actionable operational insights.
- Analyze application telemetry, logs, metrics, and traces to identify performance bottlenecks and reliability concerns.
- Improve proactive detection capabilities while reducing alert fatigue and unnecessary operational noise.
- Support enterprise observability standardization, including monitoring coverage, alert ownership, and operational readiness.
- Optimize observability configurations and telemetry consumption to balance visibility, effectiveness, and cost.
- Support and improve production workloads operating within Amazon Web Services (AWS).
- Partner with cloud engineering teams to improve infrastructure design, monitoring, and resilience.
- Identify opportunities to optimize AWS resource utilization, performance, and operational costs.
- Promote Infrastructure as Code (IaC), automated deployments, and repeatable infrastructure management practices.
- Provide advanced technical leadership during critical production incidents and complex service disruptions.
- Perform deep technical troubleshooting across applications, infrastructure, cloud services, and integrated systems.
- Collaborate with Major Incident Management teams to accelerate service restoration and minimize business impact.
