Role Description Amtech is seeking an experienced Performance Test Architect to define and drive the performance engineering strategy for enterprise-scale, distributed, cloud-native applications. The ideal candidate will bring deep expertise in performance testing, workload modeling, capacity planning, observability, application bottleneck analysis, and production-readiness validation. This role requires someone who can operate beyond traditional performance testing—partnering with architects, developers, DevOps/SRE teams, product owners, and engineering leadership to identify scalability risks early, establish measurable non-functional requirements, and ensure systems can reliably support expected business growth and peak workloads. The profile is particularly suited to someone with extensive experience leading performance engineering for high-throughput systems, microservices, cloud platforms, messaging systems, e-commerce, and customer-facing applications, including load testing, capacity planning, JVM/database analysis, observability, Kubernetes, and distributed systems. Key Responsibilities Performance Strategy & Architecture Define performance engineering strategies, standards, NFRs, KPIs, SLAs/SLOs, workload models, and release criteria. Participate in requirements, architecture, database, infrastructure, and design reviews to identify performance risks early. Design and execute baseline, load, stress, spike, endurance, scalability, capacity, volume, failover, and resilience tests. Develop realistic workload models based on customer usage, business volumes, production traffic, concurrency, and forecasted growth. Develop reusable performance solutions using JMeter, k6, Gatling, Locust, LoadRunner, NeoLoad, or similar tools. Establish production-readiness and performance quality criteria for major releases. Performance Analysis & Optimization Analyze response time, throughput, latency, concurrency, error rates, CPU, memory, network, database, and infrastructure utilization. Identify bottlenecks across UI, APIs, microservices, databases, messaging, network, infrastructure, containers, and cloud platforms. Correlate logs, APM data, distributed traces, database metrics, infrastructure telemetry, and application code to identify root causes. Perform JVM, threading, connection-pool, caching, timeout, retry, queue, and autoscaling analysis. Perform SQL performance analysis including execution plans, indexing, locking, blocking, waits, I/O, and connection pooling. Partner with engineering teams to recommend, implement, and validate performance optimizations. Lead root-cause analysis of production performance issues and recurring regressions. Scalability, Capacity & Resilience Validate horizontal and vertical scalability, autoscaling, application stability, and infrastructure capacity. Develop capacity models and recommend infrastructure sizing based on workload growth and utilization trends. Analyze Kubernetes pods, CPU/memory limits, HPA behavior, database capacity, thread pools, connections, and queue depths. Validate application behavior during peak workloads, infrastructure saturation, downstream failures, failover, and recovery. Support capacity planning and production readiness for major launches and business-critical events. Identify cloud and infrastructure optimization opportunities while maintaining performance and reliability. Automation & Continuous Performance Testing Build reusable performance testing framewo
