Innovation Engage with cutting-edge technologies, including AI-driven automation, and contribute to modernizing financial systems and operational processes across the business.* 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 frameworks, utilities, and automated regression suites.

• Integrate performance testing into CI/CD pipelines using Jenkins, GitHub Actions, Azure DevOps, GitLab CI, or equivalent tools.

• Automate test data preparation, execution, monitoring, analysis, baseline comparison, and reporting.

• Establish automated performance quality gates and regression detection.

• Track performance baselines and trends across releases to proactively identify degradation before production.

• Observability & Front-End Performance

• Define observability requirements and create dashboards for performance analysis and production-readiness assessments.

• Use tools such as Grafana, Prometheus, Splunk, Datadog, Dynatrace, New Relic, AppDynamics, Kibana, and InfluxDB.

• Evaluate browser performance, Core Web Vitals, page rendering, network activity, and responsiveness using Chrome DevTools, Lighthouse, WebPageTest, or Playwright tracing.

• Quality Engineering & Technical Leadership

• Collaborate with Quality Engineers, Developers, Architects, Database, DevOps/SRE, and Infrastructure teams on functional and non-functional quality.

• Produce clear performance reports highlighting findings, trends, risks, capacity constraints, and recommendations.

• Mentor engineers on performance engineering practices and promote a performance-first quality mindset.

• Represent Performance Engineering in architecture, design, and release-readiness reviews.

• Introduce approved AI-assisted performance engineering approaches for workload modeling, script generation, log analysis, result interpretation, RCA, and defect investigation.

• Skills & Qualifications

• Bachelor's degree in computer science, Engineering, Information Technology, or equivalent experience.

• 12+ years of Quality/Performance Engineering experience, with significant hands-on performance engineering expertise.

• Experience as a Performance Architect, Principal Performance Engineer, Performance Lead, or equivalent senior technical role.

• Strong experience with JMeter, k6, Gatling, Locust, LoadRunner, NeoLoad, or equivalent tools.

• Strong knowledge of workload modeling, scalability, capacity planning, resilience, and performance analysis.

• Experience with On-Premises, SaaS, cloud, hybrid, microservices, and distributed applications.

• Strong understanding of HTTP, REST APIs, GraphQL, WebSockets, caching, messaging, and asynchronous processing.

• Strong SQL and database performance troubleshooting skills; experience with SQL Server, Oracle, MySQL, or PostgreSQL is desirable.

• Experience with Java/JVM performance concepts including GC, memory, threading, and concurrency.

• Experience with observability/APM platforms and distributed tracing.

• Working knowledge of Linux, Windows Server, networking, containers, Kubernetes, AWS and/or Azure.

• Experience integrating performance tests into CI/CD pipelines.

• Programming or scripting experience in JavaScript, Java, Python, C#, Shell, or similar languages.

• Strong analytical, troubleshooting, communication, mentoring, and stakeholder-management skills.

• Preferred Experience

• High-throughput and highly concurrent enterprise applications.

• SaaS, retail, telecom, e-commerce, messaging, or customer-facing platforms.

• Kafka, RabbitMQ, Redis, Elasticsearch, or similar distributed technologies.

• Cloud capacity optimization and infrastructure right-size.

• Resilience and production-readiness engineering.

• AI-assisted performance analysis and engineering automation.
