Role Overview

- Own performance strategy, hands-on test engineering and root-cause analysis for distributed business-critical systems.
- Work across APIs, microservices, WebSocket/streaming services, databases, and Azure AKS infrastructure.
- Mentor junior engineers and influence release-readiness, scalability and capacity decisions.

What You’ll Do

- Define performance NFRs, SLAs/SLOs, workload models, performance budgets and production-like test scenarios.
- Build reusable k6 test suites for REST APIs, microservices and WebSocket/streaming workloads.
- Execute baseline, load, stress, spikes, endurance, scalability, capacity and resilience tests.
- Diagnose bottlenecks using metrics, logs, traces, APM data and Linux, Docker and Kubernetes signals.
- Analyze databases, caches, queues, downstream dependencies, autoscaling and AKS resource behavior.
- Integrate performance tests and quality gates into CI/CD pipelines.
- Communicate performance risks, bottlenecks and actionable recommendations to stakeholders.
- Review test designs and scripts and mentor junior performance engineers.

What We’re Looking For

- 4–6 years of hands-on performance testing or performance engineering experience.
- Strong expertise in k6 and JavaScript-based performance scripting.




- Experience building reusable frameworks with thresholds, checks, custom metrics, parameterization and test-data management.
- Experience testing REST APIs, microservices and WebSocket or other realtime/streaming systems.
- Robust understanding of workload modelling, latency percentiles, throughput, concurrency, scalability and capacity.
- Ability to diagnose bottlenecks across services, databases, caches, queues, containers and infrastructure.
- Experience with Docker, Kubernetes, Linux and cloud infrastructure.
- Working knowledge of Microsoft Azure and Azure Kubernetes Service (AKS).
- Experience using metrics, logs, distributed traces and APM tools for root-cause analysis.
- Experience in integrating performance tests with CI/CD pipelines.
- Strong communication, documentation and junior-engineer mentoring skills.

Preferred Skills

- Exposure to Model Context Protocol (MCP) or MCP-enabled performance-testing and observability workflows.
- Experience with Dynatrace, Grafana, Prometheus or Azure Monitor.
- Experience with Redis, Kafka or similar caching and messaging technologies.
- Experience in brokerage, capital markets, fintech or another low-latency, highavailability domain.
- Trading-domain knowledge.
