Test Driven Full Stack Engineer

Job description

Test Driven Full Stack Engineer AT

Role

At Brand Guarde, we're a fast-moving company focused on delivering high-quality software.

We already enforce RSpec test coverage on every PR, and we're rolling out Cypress-based E2E tests to prevent regressions.

Now we're looking for an experienced test-first engineer with a strong background in test automation — someone who can own and improve our approach to testing, CI workflows, and coverage at all levels of the stack.

You Will…

As a TDD/E2E engineer on our team, you will:

• Lead the development of automated test coverage across the entire stack:
• Backend: Write and maintain RSpec tests for models, services, API endpoints, and controller actions.
  
  
• Frontend: Build and evolve Cypress (or equivalent) tests to validate end-to-end user flows.
  
  
• Define test coverage goals for new features and ensure PRs meet those goals before merging.
  
  
• Collaborate with developers to refactor untestable code and break apart legacy flows into testable units.
  
  
• Integrate E2E tests into our CI pipeline (currently GitHub Actions), ensuring stability, reliability, and performance.
  
  
• Troubleshoot and eliminate flaky or brittle tests, especially in asynchronous flows.
  
  
• Set up shared patterns and utilities for reusable test logic, factories, test data setup/teardown, selectors, etc.
  
  
• Participate in PR reviews with a focus on test clarity, correctness, and architecture.
  
  
• Occasionally contribute to core feature development during times of high team load or project deadlines.
  
  

This is a test-focused engineering role, but we value versatility — and in a small team, flexibility is a superpower.

We are looking for…

We don't expect you to know our exact stack upfront — but you should already be familiar with most of the following, or have deep transferable experience:

1. TDD / Backend Testing

2. RSpec, Minitest, or equivalent BDD-style test frameworks

3. Designing test cases before implementation (TDD/BDD mindset)
4. Mocking/stubbing (e.g., using
   allow(...)
   ,
   instance_double
   , or equivalents)
5. Using factories (e.g., FactoryBot) to generate reliable test data
6. Testing edge cases, failure modes, and business logic
7. Structuring fast unit tests and slower integration tests

2.

E2E / Frontend Testing

• Cypress, Playwright, or Selenium for browser-based E2E testing
• Writing tests that simulate user interactions (forms, flows, permissions, etc.)
• Mocking network requests or working with seeded test data
• Choosing stable, semantic selectors and avoiding fragile DOM targeting
• Understanding how to manage flaky tests and isolate race conditions

3.CI / Dev Workflow

• Running test suites in CI pipelines (e.g., GitHub Actions, GitLab CI)
• Parallelization strategies, tagging tests, test retries
• Generating artifacts (screenshots, video logs) from failed test runs

4.Communication and Collaboration

• Creating lightweight test strategies for new features
• Documenting test architecture decisions (what to test where, and why)
• Explaining test failures clearly to other engineers
• Working alongside devs who may not yet be fluent in TDD

Bonus If You've Worked With:

• Rails, ActiveRecord, Devise, Sidekiq
• Angular, RxJS, or TypeScript-based frontend frameworks
• FactoryBot, Faker, or custom data seeding in test environments
• Feature flag systems and A/B tested flows

You're a Good Fit If…

• You've written, broken, debugged, and maintained large automated test suites.
  
  
• You understand test pyramids, isolation, mocking, and flakiness.
  
  
• You think in terms of test strategy, not just coverage numbers.
  
  
• You believe test automation is a way to empower developers — not slow them down.
  
  
• You're pragmatic, collaborative, and take responsibility for the quality of what ships.
  
  
• You're comfortable contributing to production code when needed and don't see test engineering as outside the product.
