Job summary

CloudBees Inc. is seeking a Senior Performance Engineer to shape how performance, scalability, and reliability are built into our products from the start. You will create performance tests as code, establish baselines, and partner with multiple teams to remove bottlenecks before they impact customers.

You will work hands-on across development lifecycles, leveraging production telemetry and AI-assisted tooling to deliver fast, trusted software in a hybrid Denver, CO environment.

Qualifications

• 7+ years of experience in software engineering, performance engineering, site reliability engineering, or a closely related discipline, including substantial hands‑on performance testing experience
• Strong software development skills in at least one language such as Java, Go, Python, or JavaScript/TypeScript
• Hands‑on experience with performance and load‑testing tools such as k6, Gatling, JMeter, Locust, or equivalent
• Experience automating tests and quality gates in modern CI/CD pipelines
• Strong knowledge of distributed systems, APIs, microservices, containers, Kubernetes, and cloud infrastructure
• Experience analyzing latency, throughput, concurrency, error rates, resource saturation, and capacity limits
• Experience using observability and profiling tools to isolate bottlenecks across application, database, network, and infrastructure layers
• Ability to translate business‑critical user journeys and reliability expectations into realistic workloads, measurable thresholds, and actionable engineering recommendations
• Clear written and verbal communication skills, with the ability to influence technical decisions across teams

Responsibilities

• Design and own the performance engineering strategy for the products and distributed services in your domain
• Build and maintain automated load, stress, spike, soak, scalability, and resilience tests as version-controlled code
• Integrate performance tests, thresholds, and regression detection into CI/CD workflows at the appropriate stage of the delivery process
• Partner with service owners and SRE to define meaningful performance baselines, service-level objectives, and release criteria across latency, throughput, error rates, resource use, and scalability
• Diagnose performance bottlenecks using observability data, profiling, tracing, logs, metrics, and disciplined experimentation
• Partner with software engineers, architects, SRE, product, and platform teams to design for performance early in the development lifecycle
• Create realistic, repeatable test environments, workloads, data sets, and capacity models for cloud-native systems
• Develop dashboards and automated reporting that make performance trends, regressions, and risks visible to engineering leaders
• Improve performance engineering practices, tooling, documentation, and technical standards across teams
• Coach engineers on performance testing, measurement, root-cause analysis, and automated quality practices
• Use AI coding agent (Claude code or similar) to build and maintain test suites, generate workloads, and analyze results and apply judgement to what they produce
