Job Description Job Description Stuut is transforming accounts
receivable for B2B companies—making collections smarter and faster
for companies that have historically relied on manual processes
that are labor intensive and costly. Our platform is gaining
traction with finance teams across industrials, chemicals, and
manufacturing sectors from Fortune 10 brands to scaling midmarkets.
We're backed by top-tier investors including a16z, Khosla,
Activant, 1984 Ventures and Page One. We’re hiring a Lead Software
Engineer in Test to drive the strategy, architecture, and execution
of automated testing across our platform. You’ll build and scale
the systems that ensure every release is reliable, high-quality,
and ready for customers. From designing automation frameworks to
stabilizing pipelines to shaping quality practices within product
teams, you’ll own the tooling and engineering rigor that enable us
to ship fast with confidence. This is a hands-on technical
leadership role for an engineer who excels at building scalable
test automation, influencing engineering quality culture, and
guiding teams toward high-impact, high-reliability outcomes. You’ll
turn strong test engineering into real customer value — creating
the guardrails that empower rapid innovation. What You’ll Do Set

test stages, reduce cycle times, and introduce automation and
tooling that accelerates safe deployments. Automate New Feature
Testing: partner with engineering teams throughout the development
lifecycle to define test strategy and build automation for new
features. Lead Root Cause Analysis & Triage: guide teams through
systematic debugging of failures, ensuring issues are resolved at
their true source. Influence Engineering Quality Culture: promote
strong testing patterns, testability principles, and quality-first
thinking across teams. Mentor & Level Up the Team: coach engineers
in automation best practices, framework design, troubleshooting,
and quality ownership. You Might Be a Fit If You… Have 7 years of
experience in test automation or software engineering, with at
least 3 years in a senior or lead test engineering role. Have
architected or maintained large-scale automation frameworks
supporting rapid iteration across backend, frontend, and async
systems. Are fluent in Python and TypeScript/JavaScript, and
experienced with tools such as Playwright, Cypress, pytest, or REST
API testing frameworks. Understand how to design high-signal,
low-maintenance automated test suites for modern stacks including
FastAPI, Vue.js, and event-driven systems like Inngest. Have
improved reliability of CI pipelines in environments using
Turborepo, Docker, Vercel, and AWS EKS. Are comfortable with
cloud-native infrastructure (AWS, Kubernetes, RDS PostgreSQL) and
testing distributed systems. Have a strong understanding of CI/CD
and know how to optimize automation workflows for speed, signal,
and stability. Can convert product requirements into a clear,
executable test strategy across multiple layers of the stack. Enjoy
collaborating with Product, Backend, Frontend, and DevOps teams to
