Job Summary

Job Summary

As a Performance Engineer for our Identity Security Product, you will design and execute a comprehensive performance engineering strategy. This role requires a hands-on engineer who not only identifies performance degradation but actively investigates, debugs, and implements code-level and database-level fixes. You will work to ensure our SaaS-based IAM systems are ultra-fast and scalable, while championing AI to transform performance data into actionable optimization strategies.

Key Responsibilities

• Identify, investigate, debug, and fix performance bottlenecks, memory leaks, CPU spikes, and thread contentions.

• Optimize SaaS application performance using deep knowledge of the .NET ecosystem.

• Analyze complex queries, optimize execution plans, and tune databases to eliminate deadlocks and contention.

• Apply a strong understanding of AI, LLMs, and prompt engineering to build diagnostic and automation frameworks.

• Dissect complex distributed system issues and formulate clear, actionable execution items for the development team.

• Utilize AI tools to analyze trace context, error logs, and system states for predictive recommendations and code remedies.

• Apply system design principles and patterns to build scalable performance frameworks and recommend architectural optimizations.

• Model and simulate realistic, high-concurrency identity workloads (OAuth2/OIDC, SAML, MFA).

• Implement 'Performance-as-Code' test suites using K6 or Gatling and integrate them into CI/CD pipelines.

• Collaborate with SRE to integrate chaos engineering to validate system resiliency.

• Utilize Generative AI to create synthetic test data and user behavior models from production logs.

• Harness AI-powered APM engines for autonomous bottleneck detection to reduce Root Cause Analysis (RCA) cycle time.

• Set up and maintain full-stack telemetry dashboards using tools like DataDog, Grafana, or OpenTelemetry.

Qualifications

Required Qualifications

• Bachelor's degree with 5 years of experience, or Master's degree with 3 years of experience, or a PhD in a related field.

• 5+ years of dedicated experience in Performance Engineering and development.

• Proficient development capability in .NET C#.

• Robust SQL query fine-tuning skills.

• Strong debugging, problem-solving skills, and deep familiarity with system design principles and software design patterns.

• Experience working within high-performing, cross-functional Agile squads.

Preferred Qualifications

• Background in high-throughput SaaS architectures and Identity Security platforms (IAM, Authentication, Authorization).

• Strong understanding of how to implement and leverage AI/LLM utilities to automate workflows.

• Expert command of performance testing tools like K6, Gatling, or JMeter.

• Experience with chaos engineering (e.g., LitmusChaos, Chaos Mesh).

• Experience with observability stacks like DataDog, Grafana, or OpenTelemetry.

• Experience with CI/CD pipelines (e.g., GitHub Actions, GitLab CI).
