We are seeking a Lead SDET (Software Development Engineer in Test ) to provide end-to-end technical governance across all QA layers — frontend, middleware, and backend — for a complex, multi-layered onboarding platform. This role owns the architecture of API contract testing and the data modeling of complex entity relationships (e.g., hierarchical/parent-child style structures), while ensuring that quality assumptions made at one layer (such as client-side validation) are independently verified at every downstream layer rather than trusted at face value. The ideal candidate combines strong technical leadership with the ability to set and enforce delivery governance across cross-functional teams.
Title: Lead SDET
Rate: $17/hr
Start Date: 19th October
Duration: 4 Months
Commitment: 22 Hours per Week
Location: India (Remote)
Job Type: Contractual (with the possibility of a Full-time employment extension based on performance and project needs)
