About The Position

Beast Industries is undertaking an AI-first engineering rebuild for a company that already has an audience of over 100 million people. This is a ground-up build without legacy constraints, focused on establishing quality and reliability practices from scratch using AI tools for accelerated development and enhanced detection capabilities. The role involves being part of a small team setting the quality and reliability standards for a consumer-facing platform used by millions. The work encompasses automated testing, CI/CD integration, and production monitoring within a fast-paced, AI-native engineering organization. This includes ensuring automated test coverage across various testing types (unit, integration, end-to-end, performance) to catch regressions before they impact users, implementing CI/CD pipelines with quality gates for rapid feedback on commits, and establishing production monitoring and alerting to quickly identify and address issues before users notice.

Requirements

• AI-Native: You're already using AI tools daily to write tests, diagnose failures, and move faster.
• QA Builder: 2+ years of hands-on experience building and maintaining automated test infrastructure for consumer-facing mobile or web products.
• Reliability Minded: You care about what happens after code ships. You monitor, you alert, and you follow through when something breaks in production.
• Collaborative: You work well with engineers, communicate clearly about quality risks, and help the team ship with confidence rather than slowing them down.
• Hands-on experience with test automation frameworks (Playwright, Appium, Espresso, XCTest, or equivalent), CI/CD pipelines, and at least one observability or monitoring tool.

Nice To Haves

• Experience with AI-assisted QA tools
• Mobile app testing at consumer scale
• Familiarity with SLO and error-budget concepts

Responsibilities

• Build and maintain automated test suites across mobile and backend surfaces, with a focus on coverage, reliability, and speed.
• Integrate quality gates into CI/CD pipelines, ensuring tests run on every commit and block bad code from reaching production.
• Monitor production systems for anomalies, contribute to incident response, and follow through on root-cause fixes.
• Work closely with engineers across the team to embed quality thinking into the development process, not just the release gate.

Benefits

• Competitive Salary
• Generous Medical (Blue Cross Blue Shield), Dental, Vision and company-paid Life Insurance
• Company contributions to employee Health Savings Accounts (HSA)
• 401k Plan with Safe Harbor company-matching
• Flexible vacation policy and paid company holidays
• Company-provided technology package
• Relocation assistance where applicable, including travel and company-provided housing for the first 90 days
