Position Summary

We are seeking a senior, hands-on Performance Engineering Sr. QA Manager (M3) to lead a Performance Engineering Center of Excellence and own QA delivery for a product portfolio supporting high-transaction healthcare platforms. This role is ideal for a technical leader who can improve the reliability, scalability, and performance of EMR/EHR systems while mentoring strong QA teams and influencing engineering decisions with data. The candidate will shape performance strategy, build realistic workload models, diagnose complex bottlenecks, leverage observability, guide tooling architecture, and strengthen QA processes, quality metrics, and release readiness across systems built on microservices, APIs, cloud-native platforms, and modern frontend architectures.

Key Responsibilities

Lead the Performance Engineering CoE by defining performance standards, reusable frameworks, tooling strategy, governance practices, and enablement models that scale across product lines.

Design realistic workload models, performance baselines, SLAs, and regression thresholds using production metrics, usage analytics, clinical transaction patterns, concurrency targets, throughput goals, and data volumes.

Plan and execute load, stress, spike, soak, capacity, and scalability testing for high-volume workflows, then translate results into clear engineering recommendations and remediation priorities.

Partner with development, architecture, DevOps, and database teams to identify and resolve bottlenecks across APIs, JVM, databases, caching, frontend, network, infrastructure, and cloud layers.

Define automation coverage targets, guide scalable frameworks using Selenium, Playwright, RestAssured, or equivalent tools, and use coverage thresholds as part of release quality gates.

Establish and track quality metrics across performance, scalability, reliability, security, accessibility, environment stability, release confidence, defect escape rate, and other non-functional requirements.

Lead release readiness and QA governance reviews with clear entry and exit criteria, test strategy alignment, go/no-go recommendations, defect triage discipline, test evidence, release process adherence, and transparent risk communication.

Improve QA productivity by reducing test cycle time, increasing defect detection efficiency, improving MTTR, strengthening sprint predictability, stabilizing environments, and reducing flaky automation.

Partner with product, engineering, architecture, DevOps, and QA leaders during planning, design reviews, defect triage, release readiness, and product discussions to surface risks early and influence decisions with data.

Support the Testing CoE by sharing reusable frameworks, standards, automation assets, lessons learned, and best practices that raise quality maturity across the organization.

Required Qualifications and Skills

12+ years of progressive Quality Engineering and/or Performance Engineering experience, including 4+ years in formal people management or engineering leadership roles managing QA teams of five or more engineers.
