Test Automation Engineer (Contract)

Remote

540 is seeking a Test Automation Engineer to support the DoW in building a next-generation Air Force aircraft maintenance application powered by Angular, Apigee, Kubernetes, and Google Cloud. Test Engineers on this team design and implement automated tests to ensure the platform performs reliably as it supports Air Force maintenance operations. You’ll work closely with engineers, architects, and product stakeholders to validate system integrations, improve test coverage, and ensure the platform operates reliably across distributed systems and services.

This role is offered as a contract engagement and is ideal for engineers who value flexibility, autonomy, and high-impact work. While there may be an opportunity to convert to full-time in the future, conversion is not guaranteed and is dependent on program needs.

Location: Remote within the continental United States, East Coast working hours
Citizenship & Clearance Requirement: per client requirements, candidates must be a U.S. Citizen with the ability to obtain a DoD Secret clearance
Education Requirement: Bachelor’s Degree in Computer Science or related engineering field (preferred)
Contract Duration: initial 12 month contract, 40 hours per week

WHY 540?

540 is a forward-thinking company that the government turns to in order to #getshitdone. We don’t just talk about innovation – we deliver it. We break down barriers, build impactful technology, and solve mission-critical problems.

HOW YOU’LL DRIVE IMPACT

  • Design, develop, and maintain automated tests to validate functionality across APIs, microservices, and user interfaces
  • Develop and execute integration, functional, and regression tests for distributed systems 
  • Build and maintain automated API tests for RESTful services and service integrations
  • Design and execute test suites that leverage network emulation to simulate real-world flight-line conditions (latency, packet loss, offline scenarios) 
  • Develop automated validations for client-side persistence, ensuring unsynced data survives refreshes, crashes, and device restarts within browser storage
  • Partner closely with engineers to validate microservice interactions and platform integrations
  • Participate in manual testing of user stories and features to validate requirements and expected behavior
  • Define and improve test strategies, test coverage, and automation frameworks
  • Integrate automated tests into CI/CD pipelines to enable reliable and repeatable deployments
  • Investigate and troubleshoot defects, working with engineering teams to reproduce and resolve issues
  • Create and maintain clear testing documentation, including test cases and validation strategies
  • Collaborate with cross-functional teams to ensure quality standards are maintained throughout development

REQUIRED SKILLS & EXPERIENCE

  • 3+ years of experience with programming languages such as Python, JavaScript, Java, or similar
  • 2+ years of experience developing automated tests and technical test documentation
  • Experience building or maintaining automated test frameworks using tools such as PyTest, JUnit, Playwright, Cypress, or similar 
  • Experience designing and executing integration and API-level tests
  • Proficiency with network request interception (e.g., Playwright route or Cypress intercept) to simulate backend failures and validate frontend behavior
  • Experience performing manual testing of user stories and application features
  • Experience working in Agile development environments
  • Ability to quickly learn new technologies and become proficient in unfamiliar domains
  • Strong attention to detail and ability to identify discrepancies between system behavior and requirements
  • Ability to work independently while collaborating effectively within a team
  • Strong sense of ownership with the ability to drive tasks to completion

NICE TO HAVE

  • Experience with performance testing for PWAs (e.g., Lighthouse, storage quota management)
  • Familiarity with eventual consistency models in distributed systems
  • Experience validating client-side encryption (e.g., Web Crypto API)
  • Familiarity with RESTful API design and service integrations
  • Experience with OpenAPI (Swagger) specifications
  • Experience with API gateways and API management platforms, such as Google Apigee
  • Experience working with CI/CD pipelines and automated testing environments
  • Familiarity with non-RESTful data interfaces (SOAP, WebSockets, GraphQL, etc.)
  • Understanding of core cloud architecture principles and experience with AWS or Google Cloud Platform (GCP)
  • Experience supporting U.S. Federal Government programs, particularly DoW environments

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
