Contract JavaScript developers often face challenges such as quickly adapting to new codebases, aligning with unfamiliar team workflows, and managing shifting client expectations. To address these, it's helpful to prioritize clear communication from the outset, ask detailed questions about project requirements, and leverage documentation or onboarding resources provided by the client.

Contract Javascript focuses on core JavaScript programming for various web projects, while Contract Front-End Developer emphasizes building complete user interfaces and experiences.

The choice depends on whether the project emphasizes pure scripting or full UI development.

Contract roles offer flexibility for both employers and developers, often focusing on short-term needs or specialized expertise.

What are the key skills and qualifications needed to thrive as a Contract JavaScript Developer, and why are they important?

Job description

Test Automation Developer – Playwright (using JavaScript)

Type: Contract Hourly Role – 1yr (potential to hire full time), Rate $50-$65/hr

Location: Denver, CO – Denver Tech Center (Onsite role, 5 days/week)

Unison Systems is looking for an experienced SDET (Software Developer in Test), specifically a Playwright Test Automation Developer, skilled in writing JavaScript code and not reliant on record/playback to write code. Understands test automation and is experienced implementing BDD frameworks using Gherkin/Cucumber. In this role, you will design and build scalable end-to-end test automation for modern web applications operating in a .NET and Microsoft Azure environment. You’ll work closely with Engineering, DevOps, and Product teams to improve quality, accelerate releases, and ensure reliable user experiences.


Key Responsibilities


Test Automation & Quality Engineering

  • Design, develop, and maintain robust end-to-end UI automation using Playwright (JavaScript/TypeScript preferred).
  • Implement BDD test suites using Gherkin feature files and Cucumber (or Cucumber-style tooling) to promote readable, maintainable tests.
  • Build reusable test utilities, page objects, fixtures, and helpers to increase test stability and reduce duplication.
  • Create and manage test data strategies and environment-aware configuration patterns for multi-stage pipelines (Dev/Test/UAT/Prod-like).


CI/CD & Azure Integration

  • Integrate automated test execution into Azure DevOps pipelines (build/release), enabling automated regression gates.
  • Collaborate with DevOps teams to optimize pipeline performance (parallelization, sharding, caching, environment provisioning).
  • Publish test results, artifacts, dashboards, and reporting (e.g., HTML reports, JUnit, screenshots, traces) for rapid troubleshooting.


Required Qualifications


  • Strong JavaScript development skills (TypeScript a plus), with experience writing production-grade test automation code.
  • Hands-on experience with Playwright for UI test automation (cross-browser testing preferred).
  • Experience implementing BDD using Gherkin and Cucumber (or comparable BDD frameworks).
  • Familiarity working in a .NET application ecosystem, including coordinating with .NET engineering teams and understanding typical app architectures.
  • Experience running automated tests in CI/CD, ideally using Azure DevOps.
  • Solid understanding of software testing principles: test pyramids, risk-based testing, smoke/regression strategies, and defect lifecycle.
  • Comfort with Git-based workflows, branching strategies, and pull request practices.
