ClickUp is on a mission to make the world more productive — and that starts with enabling our engineering team with the right tools, frameworks, and best practices to protect functionality and performance of the everything app for work. We’re looking for experienced Software Engineers to help us scale our test infrastructure supporting a modern, AI-powered web and mobile platform that reaches millions of users globally.

On this team, you might architect and evolve robust frontend, backend, services or mobile testing infrastructure. Contribute to unit, integration, end-to-end, API, performance, load, and scale testing frameworks across a hybrid monolith and micro-services architecture. Focus on AI-assisted testing solutions, test isolation, prioritization and quarantining strategies, test data generation, CI quality metrics, test impact analysis and flake detection and elimination. We strive to maximize reliability while maintaining velocity.

What You’ll Do

Functional Web & Mobile Test Infrastructure

• Design, build, and maintain internal tools and comprehensive frameworks supporting unit, integration, API, and UI testing using modern approaches with Jest, Locust, Flutter (iOS & Android) and Playwright
• Implement containerized, reproducible test environments using Docker and CI/CD pipelines to support local and large-scale execution
• Contribute to integration testing strategies for inter-service validation and shared dependencies

Performance, Scale, Load & Data Generation Test Infrastructure

• Architect and evolve the load, scale, and performance testing systems used to understand the limits of our system, verify system resilience and protect our critical user journeys
• Build data-generation pipelines to create realistic workloads and performance test scenarios
• Use APM tools (Datadog RUM, APM, DBM preferred) for build-over-build monitoring and troubleshooting

AI-Enhanced Test Engineering

• Evaluate and implement AI-driven tools for automated test generation and maintenance
• Integrate self-healing, intelligent failure analysis, and test recommendations into CI pipelines

Culture of Quality

• Partner with teams to adopt the tools and frameworks built by Test Infrastructure, with a shift-left strategy in mind
• Champion best practices around metrics-based test infrastructure observability and monitoring
• Mentor teammates on software architecture and design patterns

What You Bring

• Solid experience (8+ years preferred) as a software engineer in fast-paced product environments
• Expertise in TypeScript, Node and experience with test frameworks like Playwright, Cypress, Jest, Mocha, Flutter, Detox, Moropo, Locust, JMeter or custom-built tools
• Strong fullstack understanding with deep knowledge of RESTful APIs, message queues, and service oriented architecture
• Experience with Docker, local environment orchestration, and integrating tests into CI pipelines (e.g., GitHub Actions, Harness)
• A strong understanding of modern test pyramid principles, including balancing unit, integration, and end-to-end test automation and the tools and processes to measure and improve test coverage and test impact analysis
• Expertise across network layers with HAR and performance metric analysis
• Demonstrated interest or experience in AI-assisted code generation & prompt engineering using LLMs
• Passion for system design, scalability, and thoughtful failure investigation

Bonus Skills

• Built or contributed to internal tools that accelerate code quality or engineering velocity
• Familiarity with observability tools (e.g., DataDog, Sentry) for debugging and quality signals
