Senior DevOps Engineer, Application Reliability

Wellfit is the dental industry’s fintech platform, removing financial friction so patients, providers, employers, and payors can access better care. As a profitable healthcare fintech innovator, we’re transforming the patient journey and redefining what’s possible in dental care.

• We are seeking a Senior DevOps Engineer, Application Reliability to own and evolve the reliability, observability, and performance of our Azure-based application ecosystem.

• This role sits between platform engineering and application development, focusing on application-level reliability rather than traditional infrastructure SRE. You’ll partner closely with engineering teams to ensure our systems are observable, resilient, and safe to deploy—especially as we accelerate delivery through AI-assisted development and modern deployment practices.

• If you enjoy debugging real production issues, improving developer confidence through strong observability, and preventing incidents before they happen, this role is built for you.What You’ll Do

• Design and implement end-to-end observability for Azure App Services using Application Insights, Azure Monitor, and distributed tracing.

• Build and maintain actionable dashboards that surface application health, performance bottlenecks, and reliability risks.

• Analyze logs, metrics, and traces to proactively identify issues and reduce MTTD / MTTR.

• Partner with developers to instrument applications correctly and improve runtime visibility.

• Serve as a subject-matter expert on Azure App Service architecture, scaling, and performance tuning.

• Debug production issues at the application level, including C#, .NET, Angular, and SQL-related problems.

• Use tools such as Diagnose and Troubleshoot, Kudu, and App Service diagnostics to resolve complex issues.

• Automate monitoring, alerting, and common remediation workflows using PowerShell and Azure tooling.

• Reduce operational toil through better tooling, alert quality, and self-service diagnostics.

• Support safe daytime deployments, incremental rollouts, and environment stability.

• Participate in on-call rotations and lead incident response for application reliability issues.

• Write clear, high-quality root cause analyses (RCAs) focused on prevention, not blame.

• Continuously improve reliability patterns as delivery velocity increases.

• Act as a reliability partner to development teams—not a gatekeeper.

• Document best practices for monitoring, debugging, and deployment safety.

• Help lay the observability foundation required for AI-accelerated development workflows (BMAD).

• Azure Fundamentals (AZ-900) certification required.

• Proven experience in application-focused DevOps or SRE roles, with deep hands-on Azure work.

• Strong experience with Azure App Services, Application Insights, and Azure Monitor.

• Ability to read, understand, and debug .NET/C# and Angular code.

• Experience with incident response, on-call operations, and RCA writing.

• Comfort operating in fast-moving environments with increasing deployment velocity.

• Grafana, Prometheus, Datadog, or Dynatrace

• Service Bus, Event Hub, or distributed messaging

• Additional Azure certifications
