About the role
The company 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 modelling, 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.
The candidate will have responsibilities across the following functions:
Performance Strategy and 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 and Optimisation:
- Analyse response time, throughput, latency, concurrency, error rates, CPU, memory, network, database, and infrastructure utilisation.
- 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 optimisations.
- Lead root-cause analysis of production performance issues and recurring regressions.
Scalability, Capacity and Resilience:
- Validate horizontal and vertical scalability, autoscaling, application stability, and infrastructure capacity.
- Develop capacity models and recommend infrastructure sizing based on workload growth and utilisation trends.
- Analyze Kubernetes pods, CPU/memory limits, HPA behaviour, database capacity, thread pools, connections, and queue depths.
- Validate application behaviour 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 optimisation opportunities while maintaining performance and reliability.
Automation and 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 and 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 and 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 modelling, script generation, log analysis, result interpretation, RCA, and defect investigation.
Requirements:
- 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 modelling, 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 optimisation and infrastructure right-sizing.
- Resilience and production-readiness engineering.
- AI-assisted performance analysis and engineering automation.
