QA Engineer (React Native/Node.js)

About Us

MaxRewards helps 800K+ members manage their credit cards and maximize their rewards. We're an early-stage fintech startup with strong growth momentum and a lean, fast-moving engineering team.

The Role

You'll own quality across our React Native mobile app and Node.js backend—manually testing complex workflows, reviewing PRs, managing releases, and writing changelogs. You will report to a Staff Engineer and will be the primary QA voice on the team.

We ship fast. Features go from spec to production in days. You'll be expected to move quickly without cutting corners, context-switch constantly, and contribute meaningfully within your first two weeks.

What You'll Do

Review PRs with a risk-based lens—deep scrutiny on critical workflows like account syncing and payments and lighter touch on UI and niche functionality changes

Compile, run, and debug applications locally using emulators and simulators

Execute manual testing for new features, bug fixes, and improvements across iOS, Android, browser extensions, and backend APIs

Document bugs with clear reproduction steps and severity assessments, collecting device and crash logs using console output, Android Debug Bridge (ADB), and Xcode

Extensively leverage AI tools to accelerate test case generation and edge case discovery

Own the release process: coordinate builds, manage app store submissions, and communicate go/no-go

Write and maintain changelogs, translating technical changes into clear member-facing language

Contribute to automated testing as you grow in the role

Required Qualifications

1–3 years of QA experience with strong manual testing fundamentals

Experience testing mobile apps (iOS and Android) and REST APIs, including proficiency with local simulators/emulators and debugging tools like ADB and Xcode

Instinctive risk judgment—you know which changes need scrutiny without being told

Exceptional attention to detail—you catch what engineers miss

Basic JavaScript/TypeScript understanding

Interest in personal finance or credit card optimization

Nice to Have

Experience owning or coordinating app release processes

React Native/Expo experience

Exposure to AI testing tools

Automation framework experience

Early-stage startup background

This Role Is NOT for You If...

You test every PR with the same level of scrutiny regardless of risk

You need someone else to identify what's high-risk

You need days to write a bug report or process to do your best work

You're not comfortable being the only QA voice in the room

Compensation & Benefits

$75K–$95K base salary + 0.1%–0.2% equity

Up to 100% employer-paid health, dental, and vision insurance

401(k) with 100% match up to 6% (after 1 year)
