A Day in the Life of a Senior Performance Engineer As a Senior Performance Engineer, you will be the driving force behind the performance, scalability, and reliability of our solutions. Working within a collaborative R&D team, you will own the performance testing strategy from end to end, conduct dimensioning exercises, and tackle complex scalability challenges across our Java/Spring Boot applications running on Kubernetes-based platforms.
What You'll Do
Own and drive the overall performance testing strategy: load, stress, soak, spike, endurance, and capacity testing Design and execute performance test scenarios using tools like JMeter, Gatling, k6, or Locust Provide guidance to other performance engineers Define, track, and report on solution performance KPIs (response time percentiles, throughput, error rates, resource utilization) Profile and tune Java/Spring Boot applications, diving deep into JVM internals, GC behavior, heap sizing, and thread pool performance Analyze and optimize messaging protocol performance (MQTT, STOMP): connection scaling, throughput, QoS impact, and session management Conduct capacity planning and dimensioning exercises, translating business growth projections into concrete infrastructure sizing recommendations Identify and resolve scalability bottlenecks across the full stack, from application code to container orchestration Tune Kubernetes performance (resource requests/limits, HPA/VPA, pod scheduling) across platforms such as k3s, OpenShift, EKS, and AKS Diagnose container-level issues including CPU throttling, OOM kills, and I/O contention Build and maintain observability dashboards using Prometheus/Grafana Integrate performance testing into CI/CD pipelines to catch regressions early Present findings and recommendations to engineering leadership, influencing architecture and infrastructure decisions Champion a performance-first mindset across teams Must-Haves 12+ years of experience in performance engineering Hands-on with at least one major performance testing tool (JMeter, Gatling, k6, or Locust) Strong knowledge of Java/JVM internals and Spring Boot profiling (JFR/JMC, async-profiler, YourKit) Solid background in resolving common application bottlenecks (HikariCP, thread models, N+1 queries, connection leaks) Comfortable scaling up messaging protocols (MQTT, STOMP) Kubernetes performance tuning across at least two of k3s, OpenShift, EKS, AKS Capacity planning and dimensioning experience Proficient with Prometheus/Grafana Experience integrating performance testing into CI/CD pipelines Strong communicator, able to influence architecture decisions at leadership level Nice-to-Haves Kafka/RabbitMQ performance tuning (consumer lag, partition sizing, throughput) Hands-on with message broker scalability and tuning (VerneMQ, eJabberd, RabbitMQ, Vert.x, or similar): cluster sizing, topic/subscription fan-out, persistent session overhead, and connection limits Database performance tuning (Redis, MaxScale/MySQL, Oracle/GoldenGate): query plans, indexing, connection pooling Knowledge of cloud auto-scaling patterns Familiarity with IaC tools (Ansible, Terraform, Helm) for reproducible test environments Scripting skills (shell) for custom tooling Location - Remote, India/Portugal Limitation and Disclaimer: The aforementioned job description is aimed to provide an overview of the overall type and level of work being performed for this role; it shouldn't be interpreted as a complete list of all obligations, responsibilities, and qualifications needed for the job.
