Overview

We’re seeking Senior SDET with a strong background in iOS development, device profiling, and automated testing. You will own end-to-end quality across our front-end iOS stack, ensuring reliability, performance, and release readiness for Quidient’s Edge applications. This role is highly hands-on, requiring excellent engineering instincts, strong debugging skills, and a passion for improving code quality and test coverage.

This is a hybrid position, meaning that you will need to live within easy driving distance to our Technology Center in Columbia, Maryland.

What You’ll Do

Own, Build, & Automate

  • Lead QA testing for iOS applications, including feature validation, regression coverage, and performance profiling across multiple device types.
  • Build and maintain automated test infrastructure using CI/CD frameworks.
  • Develop and run profiling workflows to identify and diagnose performance constraints in CPU, GPU, memory, thermal behavior, and resource usage.
  • Integrate and validate compiled artifacts (Objective-C, C, C++) delivered by algorithm teams, ensuring compatibility and stability.
  • Create clear, repeatable test plans and documentation for features, test harnesses, tools, and findings.
  • Collaborate across iOS, Algo, Solutions, and CX teams to reproduce, troubleshoot, and resolve issues from field tests or customer feedback.
  • Contribute to continuous improvement of release workflows, code quality, and automated testing coverage.
  • Build dashboards and reporting systems that surface test results, performance metrics, and regression signals to engineering leadership.
  • Support long-term efforts to expand automation and eventually manage or influence human-in-the-loop testing processes.

What You Bring

Must-Have Qualifications:

  • Bachelor's degree in computer science, Software Engineering, or related field (or equivalent experience)
  • 5–10+ years of experience in iOS software engineering, QA engineering, or mobile test automation.
  • Strong proficiency with Swift, SwiftUI, Xcode, XCTest, and iOS profiling tools (e.g., Xcode Instruments).
  • Experience with Git/GitHub and CI/CD systems such as Xcode Cloud, Fastlane, or similar.
  • Familiarity with Objective-C and C/C++ for validating compiled artifacts and integrating with lower-level components.
  • Strong understanding of automated testing methodologies, regression testing, and performance analysis.
  • Excellent communication skills, including clear reporting on test results, defects, and performance findings.
  • Demonstrated ownership mindset, attention to detail, and ability to work independently in a fast-paced environment.
  • Willingness to work on-site in Columbia, MD, in a hybrid capacity.
  • This position is not eligible for H-1B sponsorship.
  • Meet Quidient, customer, and government security requirements, which may include, but are not limited to a background check, citizenship verification, and Criminal Justice Information Services verification.

Nice-to-Have Qualifications:

  • Experience with Android or Flutter.
  • Background in DevOps, cloud test environments, or artifact hosting systems such as JFrog.
  • Experience collaborating with Customer Experience teams to troubleshoot field issues.
  • Strong debugging background across distributed engineering teams.
  • Understanding of 3D rendering pipelines or digital content creation in the metaverse/AR/VR space.

What We Offer

Form CC-305

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.
