Software Development Engineer in Test (SDET)

Emergent builds autonomous coding agents that replace traditional software development by generating, testing, and deploying production applications directly from plain-language intent. Our systems run in production at global scale and are used to build millions of real applications. Since our public launch, we've crossed $130M in Annualised Revenue and grown to over 10M users across 190+ countries, who have built 12M+ applications on Emergent. We're backed by Creaegis, Khosla Ventures, SoftBank, Lightspeed, Together, Y Combinator, Google, Claypond and Sentinel Global. We're solving the hard part of AI-driven software creation: correctness, reliability, security, and scale in real production systems. The team is built by repeat founders, Olympiad medalists, IIT & IIM alumni, and leaders from Google, Amazon, and Dropbox. We're hiring builders who want ownership, speed, and impact at global scale. Responsibilities - Design, develop, and maintain automated tests for web applications, APIs, and end-to-end user journeys. - Build reusable automation frameworks, utilities, and test infrastructure that scale with product complexity. - Develop and maintain UI automation using Playwright or similar modern automation frameworks. - Write automated API and integration tests covering functional behavior, error scenarios, and edge cases. - Integrate automated tests into CI/CD pipelines and improve execution speed, reliability, and feedback time. - Identify product risks early and work with developers and product managers to improve testability and prevent defects. - Investigate test failures, perform root cause analysis, and improve automation stability. - Use AI-assisted development and testing tools to improve test creation, debugging, coverage, and maintenance. - Test AI-powered product workflows, including dynamic UI behavior, generated outputs, failure scenarios, and regression risks. - Take end-to-end ownership of quality for assigned features, from requirement analysis to release validation. - Track automation coverage, defect trends, and test reliability to continuously improve quality. Required skills and experience - 3–6 years of experience in software testing, test automation, or SDET roles. - Strong programming skills in Python or TypeScript. - Hands-on experience with Playwright, or an equivalent browser automation framework. - Good understanding of API testing, REST, HTTP, JSON, authentication, and integration testing. - Experience with Git, CI/CD pipelines, and automated test execution. - Strong understanding of test design, boundary-value analysis, negative testing, and risk-based testing. - Experience building or extending reusable automation frameworks. - Strong debugging and problem-solving skills, with the ability to investigate failures using logs, traces, and network requests. - Ability to collaborate effectively with engineers and product managers in a fast-paced environment. - Strong ownership, attention to detail, and clear communication. Good to have - Experience testing AI-powered applications or LLM-based features. - Familiarity with AI coding assistants and agent-based testing approaches. - Experience with mobile automation, performance testing, or observability tools. - Experience with Docker, cloud environments, and distributed systems. Benefits and Perks - Daily Meals: Breakfast, Lunch and Dinner provided. - Family Insurance: 5 Lakhs worth of coverage for you and your family. - Unlimited Paid Time Off: Take the time you need to recharge and come back refreshed. - Flexible Working Hours: Work arrangements that fit your life and commitments.
