Software Engineer in Test (SDET) - Production Code Ownership

AI overview

Take ownership of identifying and fixing bugs in production code, ensuring high product stability and reduced regressions in a fast-paced startup environment.
About Us Wing is seeking elite talent to join M32 AI (a subsidiary of Wing, backed by top-tier Silicon Valley VCs), dedicated to building agentic AI for traditional service businesses. Think of it like a startup within a corporate: fast moving and agile, with the stability of a corporate, and zero bureaucracy. If you’re driven by challenge and eager to make a significant impact in a high-caliber role, this is the opportunity you’ve been waiting for. We’re hiring an engineer whose primary responsibility is finding bugs, fixing them directly in production code, and verifying the fix end-to-end. This is not a reporting-only QA role.  If you find a bug, you own it until it’s fixed and verified. You will not focus on building new features. Your impact is measured by product stability, reduced regressions, and faster bug resolution. You Will Own
  • Actively explore and test the product without waiting for tickets
  • Identify bugs through exploratory testing, edge cases, and real usage
  • Reproduce issues locally or in staging
  • Debug frontend and/or backend production code
  • Fix bugs directly in the main codebase
  • Add regression tests for every meaningful fix
  • Verify fixes before and after deployment
  • Reduce recurring bugs and overall defect rate
  • What You Will Not Do
  • You will not only write test scripts
  • You will not hand off bugs to another engineer
  • You will not just “log tickets and wait”

  • Preferred Skills & Experience
  • Proven experience fixing bugs in production code
  • Comfortable debugging real systems (not just test environments)
  • Able to commit fixes directly (frontend, backend, or both)
  • Experience writing regression tests (unit, integration, or E2E)
  • Strong ownership mindset: find → fix → verify
  • If your past role involved only reporting bugs, this is not a fit.
  • Nice to Have
  • Startup or scale-up experience
  • Background as a full-stack or backend engineer
  • Experience working without a separate QA team
  • Familiarity with CI/CD and release validation

  • How We Evaluate You
  • During interviews, we’ll ask:

  • How you find bugs on your own
  • The last production bug you personally fixed
  • How you validate fixes and prevent regressions

  • We may include a short paid task involving:
  • Reproducing a bug
  • Fixing it
  • Adding a regression test
  • Compensation
  • INR 8 LPA - 10 LPA
  • What You Get
  • Competitive salary
  • Performance‑based bonuses tied to release quality
  • Software for Upskilling & Productivity
  • Remote-first culture
  • Work from anywhere
  • Paid Time Off
  • Health Insurance
  • High autonomy, low bureaucracy
  • Fast-track to leadership for high performers
  • US HQ Opportunities
  • Direct access to founding team
  • High visibility, autonomy and ownership
  • Optional in‑person hack‑weeks in Hong Kong, India, or London
  • A clear growth path into Head of QA as the team scales
  • Access to best‑in‑class tooling
  • We hire for output instead of pedigree. If your systems never miss a bug, we want you on the team.
