Lead Performance Reliability Engineer

Insight Global is hiring for a Lead Performance Engineer to support a large enterprise client with complex, mission‑critical applications. This role was created at the request of senior production support leadership to proactively identify and resolve performance issues before they impact the business.

We are seeking a senior, hands‑on performance expert who thrives in production environments, lives in performance data, and can diagnose issues across applications, integrations, infrastructure, and networks.

What You’ll Do
Proactively monitor production systems to identify performance degradation before users report issues
Analyze application performance KPIs including response times, percentiles (P90/P95), throughput, and error rates
Investigate performance issues across multiple layers:
Application layer (ERP and non‑ERP systems)
APIs and integrations
Network
Infrastructure / hardware
Translate non‑functional requirements into clear, actionable performance test scenarios
Partner closely with:
Production Support teams for ongoing performance issues
Project teams during go‑lives and hypercare
Provide clear, data‑driven insights to engineering and leadership during high‑impact incidents
Support upcoming enterprise go‑lives and major releases in a fast‑moving production environment

This role sits in a high‑visibility “hot seat” during critical incidents — leadership relies on this person for real‑time performance insight and direction.

What We’re Looking For
Must‑Have (Core to Success)
Strong performance monitoring and analysis experience in production environments
Deep understanding of application performance KPIs, baselines, percentiles, averages, and trends
Ability to read and interpret performance reports and turn data into actionable recommendations
Solid understanding of:
HTTP fundamentals
Network basics
Request/response behavior
Experience with modern application architectures:
Microservices
APIs
Hands‑on experience with observability and monitoring tools, such as:
Dynatrace
OpenTelemetry
Prometheus
Grafana
Elastic
Loki / Tempo
Strong analytical mindset with the ability to think beyond a single platform and diagnose issues holistically

ERP / Platform Experience (Flexible by Design)
Experience supporting large ERP platforms is highly valuable
Oracle Fusion Cloud experience is preferred, particularly in Finance, Supply Chain, or integration environments
PL/SQL knowledge is a plus
However: Candidates with SAP, PeopleSoft, or other enterprise ERP platforms will be strongly considered if performance monitoring and reliability are their core strengths
👉 When tradeoffs are required, performance engineering and reliability experience outweigh platform‑specific expertise.

Backgrounds That Tend to Do Well
We actively encourage candidates from the following backgrounds:
Site Reliability Engineers (SREs) with observability ownership
DevOps Engineers focused on monitoring, reliability, and system performance
Senior / L3 Production Support Engineers with heavy performance troubleshooting exposure
Performance Engineers who have supported large, complex enterprise systems

What This Role Is Not
Not a people management position
Not a testing‑only role
Not remote (5 days onsite)

Location & Work Model
Cleveland, OH – 100% onsite
Relocation support available
Remote work considered only as a last resort if no qualified local or relocating candidates are identified

Why This Role Matters
Enterprise production performance issues are ongoing and business‑impacting
This role plays a critical part in stabilizing complex systems
High executive visibility and immediate impact
Opportunity to shape how performance is monitored and addressed at scale
