Scotch - Software Engineer
Requirements
• 6+ years in QA or software engineering in test, including 2+ years as the senior or lead quality owner for a shipping product. • A track record of building test automation from scratch, not just maintaining someone else's suite. • Strong coding skills in Kotlin, Java, Ruby, TypeScript, or Python. You write test code that engineers are happy to review. • Hands-on experience with modern frameworks (Espresso, Maestro, Appium, Playwright, Cypress, or similar) and running them in CI. • Experience testing APIs, data integrity, and integrations between systems. • Sound judgment about risk: you know when a bug should block a release and when it shouldn't, and you can explain why. • Clear writing for different audiences, from bug reports engineers can act on to release notes the support team can use. • POS, retail, or payments experience, including card-present testing, processor certification, or PCI-aware testing practices. • Experience with device fleet management, MDM, various product release processes a plus • Experience with hardware peripherals such as card readers, barcode scanners, receipt printers, and cash drawers. • Experience with Rails test tooling (RSpec, Capybara) or contract testing (Pact). • Familiarity with feature flags (LaunchDarkly) and staged rollouts. • Experience with release-health and observability tools such as Crashlytics, PostHog, or Sentry. • Fluency with AI coding and testing tools, such as Claude Code, Cursor, or AI-assisted test generation or other vendor tools / frameworks
Responsibilities
• Own the QA strategy for the POS app, back office, and payments, deciding what gets automated, what gets tested by hand, and what blocks a release. • Build and maintain automated test suites across layers: unit and integration coverage alongside engineers, E2E tests for the back office (Playwright or similar), and API and contract tests between the POS and back office. • Wire tests into CI (GitHub Actions) so every pull request and release candidate gets fast, reliable feedback, and keep flaky tests at near zero. • Turn our release process into evidence-based gates: regression results per build, upgrade testing from older app versions, staged rollouts by ring, and clear go/no-go criteria for hotfixes. • Test on real hardware in real conditions: Elo terminals across Android and firmware versions, card readers, scanners, printers, offline mode, flaky networks, and long-running overnight soak tests. • Drive payments quality, including processor certification test runs, refund and split-tender edge cases, and failure modes like reader disconnects and processor outages. • Build test data and environments: seeded merchant data, isolated per-branch environments, and emulators so anyone can reproduce a merchant's setup in minutes. • Use AI tools to move faster, from generating test cases and test code to triaging crash logs and support tickets. • Partner with support to shorten the path from a merchant report to a reproducible bug, with the register, app version, and transaction details attached. • Track quality with a few clear metrics, such as escaped defects, crash-free sessions, release-health by version, and time from merge to store, and report on them plainly. • Raise the quality bar across engineering: review test plans in design, coach engineers on writing testable code, and make quality everyone's job.
Benefits
• Compensation: The anticipated base salary range for this position is $160,000–$170,000. Individual offers are based on a variety of factors, including experience, skills, qualifications, and internal equity. • Competitive equity package • Comprehensive medical, dental, and vision coverage • Unlimited flexible PTO
