SDET-1 | Quality Engineering (AI-Native)
š Noida | š Full-Time | š§ Experience: 2+ Years
The Mission: Beyond "Automation"
At TestMu AI, we arenāt just fixing bugs; we are deprecating the old manual-heavy testing world. We are buildingĀ Agentic Intelligenceāend-to-end AI agents that autonomously plan, author, and self-heal tests.
As an SDET-1, you aren't a "script maintainer." You are anĀ AI-first Quality Architect. You will be responsible for bridging the gap between legacy automation and the future of autonomous agentic workflows. If you want to move from "writing code that tests" to "building AI that tests," this is your seat.
The Pillars of Impact
š 1. Agentic Framework Engineering (50%)
- Architectural Excellence:Ā Build and scale deep-level frameworks (Playwright, Selenium, Appium) designed specifically for AI-driven execution.
- AI Augmentation:Ā Integrate LLMs and Agentic tools into the SDLC to automate test generation and reduce human intervention by >50%.
- Performance Coding:Ā Leverage strong DSA foundations to write highly optimized, non-blocking test code that scales with our platform.
āļø 2. Autonomous CI/CD & Reliability (30%)
- Pipeline Orchestration:Ā Design seamless "no-touch" integration into CI/CD (GitHub Actions / Jenkins) where tests trigger and analyze results autonomously.
- Root Cause Mastery:Ā Use deep-dive debugging to eliminate flakiness, ensuring our AI agents operate in a stable environment.
- Full-Stack Ownership:Ā Move beyond checklists; you own the E2E quality of your ticket/module from creation to deployed.
š§ 3. Tech Depth & Tooling (20%)
- Polyglot Mastery:Ā Solve complex technical challenges across Java, Python, or TypeScript.
- Cloud Infrastructure:Ā Validate data flows across AWS/GCP, Dockerized containers, and complex DB architectures.
The Interview Loop: Screening for the Top 1%
We look for problem solvers who thrive under pressure and think in systems, not just scripts.
- Technical Round I (SDET Leads):Ā Focus on Core DSA, live coding, and the "why" behind your framework architecture decisions.
- Technical Round II (Hiring Manager):Ā AI Hands-on Assessmentāhow you use agents today to eliminate toil and speed up your workflow.
- Technical Round III (VP Engineering):Ā Solving for Scale. Weāll discuss debugging at scale and communicating technical risks to stakeholders.
- Final Round (CEO):Ā Vision Alignmentāreadiness to lead the era of Agentic Intelligence.
Mandatory "Non-Negotiables"
- AI-Native Workflow:Ā You don't just "know" AI; you use it daily (Copilots, Agents, LLM-wrappers) to be 2x more productive.
- Engineering Depth:Ā You must be able to explain the design patterns behind your frameworks.Ā Note:Ā Candidates with only manual or basic "record-and-play" experience will not be shortlisted.
- Extreme Ownership:Ā You take pride in shipping zero-defect features and don't wait for instructions to fix a broken pipeline.
Your Growth Trajectory
TestMu AI is a high-velocity environment where you will receive direct mentorship from Senior Leadership. Your path to Senior SDET or Quality Architect isĀ performance-based, not tenure-based. We promote based on the complexity you can solve, not the years on your resume.
Perks of the Future
- Health & Wellness:Ā Comprehensive insurance for you and your family.
- Fuel for Innovation:Ā Daily catered gourmet meals at our Noida HQ.
- Seamless Transit:Ā Safe, reliable cab facilities for eligible shifts.
- Pod Culture:Ā Dedicated budgets for offsites, team building, and continuous learning.

What you'll own
The quality charter. Define and evolve the testing strategy ā web application, dashboards, APIs, webhooks, and customer integrations. Establish release criteria, coverage expectations, and quality gates that engineers actually respect because they're fast and they catch real bugs. Automation at scale. Build and maintain end-to-end and API automation suites that run on every PR and give a trustworthy signal. Own the flake rate. Design for parallel execution, deterministic test data, and fast feedback ā a suite nobody trusts is worse than no suite. Performance and reliability. Design and run load, stress, and soak tests against APIs and the platform. Profile results, isolate bottlenecks with the engineers who own the service, and set up the monitoring that tells us about degradation before a customer does. Leverage through tooling, including AI. Use whatever gets coverage up and cycle time down: LLM-assisted test case generation from specs, AI-assisted authoring and maintenance of automation, synthetic test data generation, log and failure triage. We expect you to be opinionated about where these tools genuinely help and where they produce impressive-looking noise. Raising the bar. Partner with product and engineering from spec through release so quality risk is surfaced during design, not after code freeze. Mentor the QA team and build the practices ā bug triage discipline, root cause analysis, prevention over detection ā that outlast any single release.
What we're looking for
Must have
3ā6 years in QA roles, with meaningful ownership of automation frameworks rather than only executing existing suites.
Strong test automation skills with a modern framework ā Playwright, Cypress, or Selenium ā and solid coding ability in Python, JavaScript/TypeScript, or Java. You should be comfortable reading application code, not just testing around it.
API testing experience: REST, auth, webhooks and asynchronous event flows, contract testing, and tooling such as Postman, REST Assured, or Pact.
Hands-on CI/CD integration ā GitHub Actions, GitLab CI, Jenkins, or equivalent ā including making suites fast and reliable enough to gate merges.
Working knowledge of SQL for validating data correctness, and comfort with logs, traces, and observability tooling for debugging.
Rigorous, systematic thinking about edge cases and failure modes, and the communication skills to make quality risk legible to product and leadership.
Nice to have
Experience testing AI, ML, or LLM-based products, and comfort with the reality that outputs are probabilistic rather than deterministic. Familiarity with Docker, Kubernetes, or cloud infrastructure for standing up test environments.
Performance and load testing with k6, JMeter, Gatling, or Locust, plus the analytical ability to turn results into a specific, actionable bottleneck. Exposure to enterprise SaaS with real integration surface area, or to security and compliance testing expectations of enterprise buyers. - Experience as the first or most senior quality voice on a team.
What we offer
Competitive compensation with equity. Direct ownership of a charter that materially affects how enterprise customers experience our product.
Proximity to frontier AI systems in production, and the freedom to use modern tooling to do your job well.
A fast-moving team where the distance between an idea and a shipped change is short.
