Senior Software Development Engineer in Test

Stord is a commerce-enablement technology and fulfillment company building a unified operating system for the modern supply chain. The Senior Software Development Engineer in Test will build test automation infrastructure, AI-assisted testing tools, CI/CD quality gates, regression coverage, and load/performance testing frameworks from the ground up while partnering with engineers, engineering managers, and product managers.

Responsibilities:

• Build and maintain scripts across every layer of the test pyramid: API, integration, end-to-end and load tests
• Partner with PMs to convert their most critical smoke suite user flows into automated coverage
• Build Playwright-based E2E suites covering [Product Group]'s golden-path user journeys
• Wire test suites into GitHub Actions CI, gating releases on passing coverage
• Own suite health standards and outcomes — flake reduction, runtime, and reliability as coverage grows
• Build and refine tooling that turns acceptance criteria and user stories into test plans and automated test scripts
• Evaluate and integrate AI-assisted test generation tools into the team's day-to-day workflow
• Cut the manual effort required to interpret execution results, validate outcomes, triage suites, and keep coverage current as product ships features
• Build and maintain a regression test register mapping critical paths to automated coverage
• Wire coverage reporting into a shared dashboard and keep the dashboard accurate as coverage expands
• Build load and performance test frameworks that engineers can employ in a variety of applications
• Partner with engineers to define and validate performance thresholds before release
• Ensure critical services are load- and soak-tested ahead of peak season

Requirements:

• Test automation frameworks — You've built and maintained production E2E suites (Playwright or equivalent), not just written individual test cases
• CI/CD integration — You can wire test suites into GitHub Actions (or equivalent) and configure release gates that actually block bad merges
• Programming proficiency — JavaScript/TypeScript, Python, or similar. You write test automation as real software: structured, reusable, maintainable
• API/contract testing — Hands-on experience with contract test tooling (e.g. Pact) or API test tooling (e.g. Postman)
• Load/performance testing — Experience with load testing tools (e.g. k6, Locust) or equivalent
• Directed AI-assisted development — You use AI coding tools as a productivity multiplier while keeping your own technical judgment in the loop
• CLI-native workflow — You operate primarily from the terminal and script your own tooling rather than relying on GUI test recorders
• Ownership & Accountability — You own features end-to-end and take pride in what you ship. You follow through from design to production and don't drop things
• Strong Communication — You can explain technical decisions and trade-offs to engineers, PMs, and stakeholders. You ask good questions and listen well
• Collaborative Approach — You work well with others, give constructive code review feedback, and actively seek input from teammates
• Production Mindset — You prioritize reliability and user impact. You think about failure modes, monitoring, and operational concerns as part of your design process
• Learning Agility — You're comfortable with rapidly evolving AI/ML technologies and tools. You stay current without chasing hype
• Experience building a test automation function from scratch, not just extending an existing one
• Experience partnering directly with PMs on acceptance criteria and Golden Path journey definition
• Familiarity with coverage tooling and using coverage data to prioritize test investment
• Hands-on exposure to AI-assisted test generation tooling specifically, not just general-purpose AI coding assistants
• Experience in e-commerce, logistics, or supply-chain domains
• Familiarity with [Shopify / WMS-TMS / billing systems]
• Experience with security/dependency scanning tools in CI
