Overview Solstice Analytics is building the operating system for modern supply chain, a unified platform handling Order Management, Warehouse Management, Transportation, and Consumer Experience for leading brands across commerce. Our Commerce suite is the layer that sits closest to end customers: Shopify-embedded storefront components, checkout extensions, and a brand-facing portal that merchants use to configure and manage the experience. Quality here is not an abstraction. It is what a brand's customer sees when they check out. As a Senior Software Engineer in Test on Commerce, you own quality engineering for this product surface. You execute structured manual QA to hold the quality standard today, while systematically building the automation infrastructure that raises the ceiling over time. You will define what "tested" means across our Shopify apps, checkout extensions, and brand portal, build the tooling to enforce it, and operate as the quality authority on a team that treats reliability as a competitive advantage. If you are an engineer who takes quality personally, thrives in an environment where the practice is yours to shape, and wants to do technically serious work on a product surface that real customers depend on every day — this role was built for you. Why This Role Establish the quality standard — you shape how quality engineering is practiced in Commerce; the decisions you make early become the foundation the team builds on High-visibility product surface — our Shopify components and brand portal are what merchants and their customers interact with every day; quality here has a direct line to brand retention Real technical scope — Shopify app testing spans checkout extensions, theme app blocks, storefront embeds, and a TypeScript-first service layer; this is not a forms-and-clicks automation job AI-forward environment — Solstice Analytics has made AI adoption a company-level mandate; you will work in an environment where AI-assisted development is the norm Leadership investment — the Commerce team has the direction and the motivation to make quality infrastructure a first-class priority What You'll Do Manual QA and Quality Coverage Serve as the quality gate for Commerce feature releases. Write and execute test plans, run structured regression passes before releases, and document coverage gaps with enough fidelity that engineers can act on them immediately. Manual QA here is the bridge you build across while automation catches up, not a permanent operating mode. Test Automation Infrastructure Build an E2E test suite covering key customer journeys across the storefront and brand portal, wired into CI so regressions are caught on every PR. Make it easy for engineers to add coverage as a natural part of shipping. Shopify-Specific Quality Own the quality strategy for Solstice Analytics 's Shopify-embedded products: storefront app blocks, checkout extensions, onboarding flows, and the brand configuration interface. Define the right mix of automated and manual coverage for a surface that spans multiple merchant themes and checkout environments. Maintain a structured cross-theme QA playbook for compatibility scenarios that require human verification. Quality Strategy Define coverage matrices and quality gates tied to Commerce's product areas: Protect, Engage, Resolve, Unbox, and Renew. Surface quality metrics to the team so regressions and
