Senior QA Tester (Mac, Windows, iOS, Android)

I'm the co-founder of HardStop. We build system-level apps that block adult content across Mac, Windows, iOS and Android.

We're shipping quickly and looking for another Senior QA tester to work alongside our current tester, keeping testing and releases moving.

You'll:
- Test new features, bug fixes and release candidates
- Try to find ways around the blocking and cooldown protections
- Test across different devices and networks
- Write clear bug reports with reproduction steps and recordings
- Retest fixes and work directly with our developers

You should have 3+ years of mobile and desktop manual QA experience. Experience with system-level apps, VPNs, network filtering or parental controls is a strong plus. You should be thorough, communicate clearly and enjoy finding things others miss.

This is a remote, part-time role, 20-30 hours a week to start, with long-term potential. The salary range is $1,700-3,900 USD/month.

To apply, you must include both of the following. Applications missing either one will not be reviewed.

1. A Loom link at the top of your cover letter, explaining why you're a good fit for the role.
2. A list of the devices you own and which platforms you can test on: Mac, Windows, iOS and Android.

I review applications myself. Applications without both a Loom and your device list won't be considered.
