Core Responsibilities

Primary Functions

Define, own, and drive the organization-wide performance engineering strategy and roadmap, aligning it with key business objectives and growth projections.
Architect, design, and lead the implementation of sophisticated, reusable, and scalable performance testing frameworks for our complex, distributed systems.
Spearhead and conduct in-depth performance, scalability, load, and stress testing for business-critical applications and microservices to ensure their robustness.
Perform deep-dive analysis of performance results to identify system bottlenecks, architectural flaws, and optimization opportunities across the entire tech stack (hardware, software, network, cloud).
Collaborate intimately with development, DevOps, and product leaders to embed performance engineering principles early and throughout the software development lifecycle (Shift-Left approach).
Establish, govern, and monitor critical key performance indicators (KPIs) and service level objectives (SLOs) for application performance, latency, and availability.
Lead the selection, implementation, and mastery of advanced Application Performance Monitoring (APM) and observability solutions (e.g., Dynatrace, New Relic, Datadog).
Perform expert-level performance analysis and profiling of application code, database queries (SQL/NoSQL), and system internals to pinpoint the root cause of performance degradation.
Act as the chief performance consultant to engineering teams, providing authoritative guidance on performance tuning, code optimization, and scalable architectural patterns.
Direct and execute comprehensive capacity planning and forecasting initiatives to guarantee our infrastructure can seamlessly support future user growth and traffic surges.
Mentor, coach, and develop the skills of senior and junior performance engineers, cultivating a center of excellence and a strong culture of performance awareness.
Create and present compelling, data-driven performance analysis reports, findings, and strategic recommendations to both technical and executive-level stakeholders.
Champion the automation of performance testing and analysis processes within our CI/CD pipelines to enable rapid, continuous performance validation and feedback.
Proactively troubleshoot, diagnose, and resolve the most complex production performance incidents, serving as the highest point of technical escalation for performance issues.
Define and ratify the non-functional requirements (NFRs) for performance, scalability, and reliability for all new major projects and feature initiatives.
Review and provide critical feedback on architectural designs and technical proposals to proactively identify and mitigate potential performance and scaling risks.
Lead the design and execution of resiliency tests and chaos engineering experiments to rigorously validate and improve the fault tolerance of our systems.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to investigate performance anomalies or customer-reported slowness.
Contribute to the organization's broader data and technology strategy and roadmap, ensuring performance is a foundational pillar.
Collaborate with business units to translate data needs and user experience expectations into concrete engineering and performance requirements.
Participate in sprint planning and agile ceremonies, providing performance-related insights and effort estimations for key initiatives.
Evaluate and pilot emerging performance engineering tools, technologies, and methodologies to continuously enhance our organizational capabilities.
Develop and champion best practices, creating clear documentation and training materials to empower the entire engineering organization.
