About the Role
We are looking for a Senior SDET to help us evolve the automation for our mobile application. While we currently use internal tools, we are looking for someone who can help us evaluate and transition toward more modern, industry-standard frameworks. You will help define the long-term mobile automation strategy and tooling for the NX mobile client.
We need a Senior engineer who operates with high independence, identifying coverage gaps and ensuring our validation happens as early as possible in the development lifecycle.

What you’ll be doing

Mobile Automation & Evolution

  • Modernize our stack: Evaluate and help implement reliable open-source or commercial frameworks (such as Appium or similar) to improve how we test our mobile application.
  • Layer-appropriate testing: Apply the testing pyramid to ensure we are testing at the right level - strengthening API and integration automation to reduce over-reliance on brittle UI tests
  • Shift-Left focus: Proactively define test scenarios and identify risks early in the pipeline, ensuring quality is integrated from the start.
  • Maintainable Code: Maintain clean, readable, and maintainable Python code that follows high engineering standards.


Reliable Feedback & CI

  • Stable Results: Ensure that automated tests provide fast, trustworthy feedback in the CI pipeline by systematically reducing test flakiness.
  • Gatekeeping: Help improve smoke and regression gating to ensure only high-quality code reaches production.
  • Git Excellence: Maintain a professional, documented commit history and participate in thorough code reviews.

Diagnostics & Root Cause Analysis

  • Troubleshooting: Analyze and troubleshoot failures using product logs, system diagnostics, and network traffic dumps.
  • System Understanding: Investigate issues across the stack - whether they stem from the application itself or the backend services it interacts with.
  • Clear Communication: Clearly communicate root cause and next actions when failures indicate product vs test issues.


What you bring

  • 5+ years of commercial experience in software development or test automation.
  • Strong Python (3.10+) with solid programming fundamentals.
  • Mobile Automation: Proven experience automating mobile applications on both Android and iOS.
  • Autonomy: Ability to operate with high independence on complex problems and take full ownership of your projects.
  • Deep Diagnostics: Strong skills in analyzing logs and traffic to find the source of a bug.


Nice to Have

  • Mobile Infrastructure: Experience with various mobile automation frameworks (native or cross-platform) and managing testing environments, including physical devices or cloud-based device farms.
  • Web Automation: Experience with modern web automation tools (Playwright preferred).
  • DevOps & CI/CD: Familiarity with GitLab CI pipelines, containerization (Docker), or orchestration (Kubernetes).
    Innovation: Interest or experience in using AI-assisted testing tools to improve productivity or coverage.

Behavioral Expectations

  • Proactively identifies risks and long-term improvements.
  • Takes a pragmatic, risk-based approach to quality.
  • Helps unblock teammates and improves the overall effectiveness of the automation team.

  • Competitive compensation  
  • Paid time off

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.

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.
