What does a Senior JavaScript Engineer do?

A Senior JavaScript Engineer is responsible for designing, developing, and maintaining complex web applications using JavaScript and related technologies. They often lead development teams, make architectural decisions, and ensure best coding practices are followed. In addition to writing code, they may mentor junior developers, review code for quality, and collaborate with cross-functional teams to deliver high-quality software solutions.

What are some common challenges faced by Senior JavaScript Engineers when leading projects with cross-functional teams?

Senior JavaScript Engineers often encounter challenges such as aligning frontend and backend development timelines, ensuring code quality across distributed teams, and effectively communicating complex technical concepts to non-technical stakeholders. Managing dependencies between various team members and integrating new technologies or frameworks can also present difficulties. Successful engineers overcome these challenges by fostering clear communication, implementing robust documentation, and promoting collaborative problem-solving within agile workflows.

What are the key skills and qualifications needed to thrive as a Senior Javascript Engineer, and why are they important?

To thrive as a Senior Javascript Engineer, you need deep expertise in JavaScript, modern front-end frameworks (like React or Angular), and a solid grasp of software engineering principles, typically supported by a degree in computer science or equivalent experience.

Job description

Overview

We are a cutting-edge Defense Innovation Company seeking a Senior QA Engineer to join our engineering organization and raise the bar for quality across our web application portfolio. This is not a manual testing role - it is a hands-on, heavy coding position for an engineer who treats test automation as a software discipline. You will architect, build, and maintain automation frameworks with the same rigor applied to production code, with Playwright at the center of your toolkit.

You'll operate with the autonomy and pace of a startup engineer, backed by the scale and resources of an enterprise. The ideal candidate has thrived on small, fast-moving teams and knows how to deliver quality at speed without heavyweight process.

This role is ideally based near one of FTI's office locations in Chesapeake, VA, Beavercreek, OH, Colorado Springs, CO, or Northern Virginia. Candidates in these markets will receive primary consideration. Exceptional remote candidates with highly relevant experience may also be considered.

Responsibilities
  • Design, develop, and maintain robust end-to-end automation suites for complex web application workflows using Playwright with TypeScript/JavaScript
  • Leverage frontier LLM models to increase development velocity and code quality
  • Architect scalable, maintainable test frameworks and shared libraries adopted across multiple engineering teams
  • Integrate automated testing into CI/CD pipelines to enable fast, confident, continuous delivery
  • Write production-quality code daily - page objects, fixtures, custom utilities, API test harnesses, and tooling
  • Partner with developers, product managers, and DevOps to shift quality left and embed testability into design and architecture decisions
  • Triage, root-cause, and drive resolution of defects and flaky tests; champion test reliability and meaningful coverage metrics
  • Mentor engineers on automation best practices and code review test code with a critical eye
  • Evaluate and introduce tools and practices that improve quality engineering velocity
Education/Qualifications

Required Qualifications

  • Must be a U.S. Citizen AND possess an active U.S. Dept. of Defense Secret security clearance with TS/SCI eligibility.
  • Bachelor's degree in a STEM field (required)
  • 5+ years of software quality engineering or software development experience
  • Extensive, demonstrable experience using Playwright to automate workflows in modern web applications
  • Strong professional experience writing JavaScript/TypeScript - you will be evaluated as a coder
  • Experience working in startups or small, fast-moving teams where you owned outcomes end-to-end
  • Solid understanding of CI/CD practices and integrating automated tests into build pipelines (e.g., GitHub Actions, GitLab CI, Jenkins, ADO)
  • Deep knowledge of testing strategy: E2E, API, integration, and component testing trade-offs
  • Strong debugging skills across the stack - browser internals, network traffic, async behavior, race conditions
  • Excellent communication skills and the ability to influence quality practices across teams

Preferred Qualifications

  • BS in Computer Science or a closely related field .  MS in Computer Science (preferred)
  • Experience with cloud platforms - GCP, AWS, or Azure
  • Experience with API testing, contract testing, or performance/load testing
  • Familiarity with containerization (Docker, Kubernetes) and infrastructure-as-code
  • Prior experience with scaling test automation in a large engineering organization

For this role, the compensation range for candidates in Colorado is $140K- 160K.

*Note: Starting pay will be based on a number of factors and commensurate with qualifications & experience. FTI has a location-based compensation structure; there may be a different range for candidates in other locations.
