That’s the future that US Mobile is building: a software platform built truly for the 21st century and the age of 5G and IoT, with world class engineering, best-in-class user experience, and features that will define the next generation of connectivity.

At the core of it all, we have a team and culture that has been recognized by Forbes as one of the top 500 best startup employers in the US. Our team spans diverse backgrounds, cultures, and stories, with employees coming from 20+ countries.

We're a venture-backed company entering hypergrowth, having recently ranked 94th on Inc 5000's fastest-growing private companies in America, and we’re looking for someone exceptional to join our team.

You will work closely with Engineering, Product, and DevOps to ensure high-quality releases in a fast-paced environment. This role requires a strong technical background, excellent problem-solving skills, and the ability to work independently.

• Own, maintain, and expand the existing end-to-end automation test suites.
• Design, develop, and execute automated tests using JavaScript-based frameworks (e.g., Playwright, Cypress, or similar).

• Strong proficiency in JavaScript and experience building automation frameworks from scratch.
• Solid experience with modern automation tools (Playwright, Cypress, WebdriverIO, or similar).
• Strong expertise in API automation and tools like Postman, Newman, SuperTest, or similar.
• Experience working with AWS services (CloudWatch, S3, Lambdas, API Gateway, EC2, etc.).
• Experience with CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, etc.).
• Strong understanding of software testing best practices and E2E testing strategy.
• Ability to operate independently, take ownership, and deliver results with minimal direction.
• Excellent communication skills and the ability to collaborate across teams.
• Experience with infrastructure-as-code or serverless frameworks.
• Familiarity with microservices and event‑driven architectures.
• Experience with mobile automation (iOS/Android) is a plus.
• Competitive salary - $110k‑130k (NYC based, in office Monday-Wednesday)
