Learning modules

Track Overview

The Senior Automation Engineer track teaches you to design and lead sophisticated testing systems at scale. You'll learn to architect frameworks using SOLID principles, integrate tests deeply into CI/CD pipelines, test complex systems including performance and contract testing, master observability and telemetry, and mentor engineers through code review. This track positions you as a subject matter expert who can make strategic decisions about tooling, architecture, and team processes.

You'll move beyond "writing tests that pass" to "designing systems that catch real problems, scale efficiently, and give teams confidence in their releases." You'll learn to think about testing as an investment with measurable ROI, advocate for testing practices at the architectural level, and teach others through review and mentorship.

Prerequisites

• Completed Mid-Level Automation Engineer track or 2+ years of production test automation experience.
• Advanced JavaScript/Python: Design patterns, dependency injection, closures, decorators. Comfortable reading OOP and functional code.
• Playwright or Selenium mastery: Deep understanding of framework internals, plugin systems, custom reporters.
• CI/CD platform experience: GitHub Actions, GitLab CI, or Jenkins. Comfortable with YAML config and debugging pipelines.
• HTTP/REST API expertise: OAuth, authentication flows, contract testing concepts. Comfortable working with API documentation.
• Linux/Docker basics: Containers, environment setup, troubleshooting in containerised environments.
• Code review experience: You've reviewed others' tests and received feedback on your own code.

Learning Path

Master senior-level expertise through these modules:

Capstone Project: Enterprise Testing Architecture

Design a scalable testing architecture for a complex microservices application.

You'll demonstrate senior-level thinking across multiple testing dimensions:

• Design a three-layer framework using SOLID principles and dependency injection
• Create a contract test suite for inter-service API boundaries
• Implement performance baseline tests with SLO-based thresholds in CI
• Set up distributed tracing and structured logging for debugging failed tests
• Build synthetic data pipelines for edge cases without exposing PII
• Establish code review standards and mentor team members through feedback

Outcome: A comprehensive testing strategy documentation and reference implementation. You'll demonstrate the ability to think strategically about testing ROI, make architectural decisions that scale, and lead teams toward better testing practices.

Time Commitment

10–12 weeks at 12–15 hours per week. This track assumes you're applying concepts to real production systems. You'll spend significant time reading documentation, experimenting with new tools, and reviewing industry best practices.
