Senior QA Engineer – Mobile & Payments

Strong Role for Senior QA Engineers in Mobile/Consumer Tech

This position sits at the intersection of two high-demand specializations:
mobile QA and in-app purchase/subscription testing — areas where experienced engineers are genuinely scarce. Building expertise here makes you highly sought-after as subscription-based app models dominate consumer software.

Compensation: The $150–$170K range is competitive for a Senior QA Engineer in the US, sitting at or slightly above market median for this level in major tech markets (Glassdoor/Levels.fyi benchmarks typically show $130–$160K for senior QA in mid-tier cities). Equity adds meaningful upside for a profitable, bootstrapped company at this revenue scale.

Green Flags:

• $300M+ annual revenue, bootstrapped and profitable — no layoff risk from funding cycles.
• QA is embedded in engineering, not siloed — a signal of genuine quality culture.
• Unlimited PTO, autonomy, and wellness/learning budgets suggest strong work-life balance intent.
• Custom hardware + firmware testing exposure adds rare, differentiated experience to your resume.

Career Development: You'll build skills in automated mobile testing (Android + iOS), payment systems QA, and cross-stack test architecture — all transferable to any consumer app company. The collaborative, feedback-rich culture described is a strong signal for professional growth.

Watch For: As a startup without investors, growth trajectory and leadership direction depend heavily on founder decisions. Probe this during interviews.
