Software Development Engineer in Test (SDET) - Bangalore, Karnataka, India

Originally posted 11 September 2026 by the employer — open 4 days.

Own end-to-end quality and release certification for an AI-native product built on Next.js, React, TypeScript, Django, PostgreSQL, Redis, GraphQL, Airflow, MCP-based AI agents, Kubernetes, Helm, and Docker.

About the role

This role involves owning end-to-end quality and release certification for a full-stack platform built on Next.js, React, TypeScript, Django, PostgreSQL, Redis, GraphQL, Airflow, MCP-based AI agents, Kubernetes, Helm, and Docker.

What you'll do

• Own test strategy and automation across the stack: unit/component tests (Vitest, React Testing Library), API/integration tests (pytest, pytest-django, GraphQL), and UI-driven end-to-end tests (Playwright) against real workflows.
• Own release certification: define exit criteria, run and triage full regression suites, and give a clear go/no-go signal per release.
• Maintain functional coverage for core workflows including project/variant management, GDS and model linking, test bench execution, regression dispatch and reporting, compliance/RTM tracking, sharing/permissions, and notifications.
• Build test coverage for the AI Agent Workspace: prompt/response evaluation harnesses, tool-call correctness, contract tests for MCP-based agent tool servers, RAG pipeline retrieval/grounding accuracy, agent memory and session-persistence correctness, agent regression/eval suites, and guardrails.
• Design and execute non-functional testing: API/GraphQL performance and load testing, resilience/failure-injection testing for async job pipelines, and baseline security testing (authN/authZ, RBAC, input validation).
• Integrate and maintain automated quality gates in CI/CD, including flake detection, test data seeding/cleanup, and environment readiness checks.
• Use AI coding agents daily to generate/maintain tests, analyze failures, and turn bug reports into reproducible automated tests.

What you'll need

• 3 to 5 years in software quality engineering, test automation, or SDET roles, with demonstrable ownership of release certification for a production system.
• Strong hands-on experience with Playwright (or equivalent) for UI-driven end-to-end testing of React/Next.js apps, including async state and long-running workflows.
• Strong hands-on experience with API/backend test automation (pytest, pytest-django, or equivalent), including REST and GraphQL testing.
• Working knowledge of component/unit testing with Vitest, Jest, or React Testing Library.
• Solid understanding of relational databases, test data management, and seeding/cleanup for repeatable automated runs.
• Experience testing asynchronous, job-queue-based, or event-driven systems (Redis, background workers, Airflow or similar orchestration pipelines).
• Experience designing non-functional test strategies: performance/load, resilience/chaos testing, and baseline security testing.
• Practical experience with Docker, Kubernetes, and Helm, and CI/CD pipelines as quality gates.
• Strong, demonstrable experience using AI coding agents (GitHub Copilot, Claude Code, Cursor, or similar) to generate and maintain test automation, with the judgment to validate AI-generated tests.
• Understanding of AI-agent/LLM application testing: prompt/response evaluation, tool-call verification, and agentic regression/guardrail testing.
• Excellent defect triage and cross-functional communication skills; ability to make an independent, defensible release go/no-go call.
