Cellebrite Performance Technical Lead 

Israel, Center District, Petah Tikva 

842228339

Position Overview:

We are looking for a Performance and Automation Technical Lead to drive the definition, implementation, and scaling of our performance and automation testing strategy across the platform. This is a hands-on leadership role that requires deep technical expertise in AWS services (including Lambda, EKS, and S3), infrastructure-as-code (Terraform, Helm), and modern automation and performance testing tools.

The ideal candidate has over 8 years of experience, with at least 5 years in a technical leadership role. They must be able to guide cross-functional teams, define test levels and scenarios, and provide support on implementation while maintaining a strategic view of system-wide quality and performance. A strong “can-do” approach, deep understanding of microservices, and the ability to zoom out and see the big picture are essential for success in this role.

Responsibilities:

· Own and evolve the end-to-end test automation and performance strategy for complex distributed systems.

· Design and implement scalable automation frameworks for UI, API, and integration testing using modern tools (e.g., Selenium, Cypress, Playwright).

· Lead performance testing initiatives using tools like JMeter, k6, Gatling, and identify and troubleshoot system bottlenecks.

· Drive integration of automation and performance tests into CI/CD pipelines using GitHub Actions, Jenkins, or equivalent.

· Provide hands-on leadership in using AWS services (Lambda, EKS, S3, RDS, API Gateway, etc.) with infrastructure as code via Terraform and deployment automation using Helm.

· Collaborate with R&D, DevOps, and QA to align on quality goals and implement them across services and teams.

· Define and document test level scenarios (unit, integration, system, performance, chaos) and coach teams on how to adopt them.

· Build observability into the testing and performance lifecycle using tools like Grafana, Prometheus, Datadog.

· Take ownership of system-wide test coverage, helping teams understand the big picture and ensuring resilience and scalability.

• 8+ years of experience in software quality, test automation, and performance engineering.
• At least 5 years in a technical leadership or staff-level position.
• Strong hands-on expertise with AWS services: Lambda, EKS, S3, CloudWatch, RDS, etc.
• Proficiency with Terraform, Helm, and Git-based workflows (GitHub Actions).
• Experience with microservices, REST APIs, and asynchronous messaging systems in distributed cloud environments.
• Proven ability to work across teams, guide implementation, and help define testing levels and approaches.
• Expertise in automation tools (Selenium, Cypress, Playwright) and performance testing tools (JMeter, k6, Locust).
• Strong coding/scripting background (e.g., Python, JavaScript, or similar).
• Experience with observability and APM tools (Datadog, etc.).
• Familiarity with chaos testing, failover validation, and resiliency patterns.
• Exposure to security/performance hardening of services in production.
• Strong leadership and collaboration skills across R&D, DevOps, and QA.
• "Can-do" approach, with the ability to solve problems proactively and independently.
• Ability to zoom out and see the big picture while owning implementation-level details.
• Excellent written and verbal communication.
