Senior Software Engineer, Full-stack (NoCode / Nexus / Genesis) – Japan (Work Authorization Required)

| Global Market for QA   As the speed of software development accelerates to unprecedented levels, QA alone remains trapped in an outdated, labor-intensive model. Test engineers are in chronic shortage, outsourcing costs continue to rise, and even with SaaS tools in place, operations remain a persistent bottleneck. This dilemma is not a tooling problem—it is a structural problem within QA itself. Now, for the first time, the conditions to transform this structure are in place. AI has reached a level where it can autonomously make decisions, act, and improve. This is the moment—the only moment—to fundamentally redefine QA, which has long depended on human labor. We are here to seize this opportunity.   | About Us   Autify, Inc. is a startup founded in San Francisco. As the first Japanese team to graduate from Alchemist Accelerator, we have been challenging the global market with our mission: “Enhance people’s creativity by technology.” Since our launch in 2019, we have systematically eliminated human dependency in QA. Autify Genesis standardizes QA workflows by using AI to handle documentation tasks such as test design, planning, and reporting. Autify Aximo (available in the U.S. only as of April 2026) enables autonomous test execution, where AI interprets UI and runs tests without scripts. Autify Nexus continuously executes scripted regression tests with high speed, low cost, and stability. By placing AI across every phase—thinking, executing, and repeating—we are building a world where QA operates independently of human intervention. Today, these products have evolved into an integrated platform that supports the entire QA lifecycle, from test design to execution. Autify AI Coworker brings together these products with professional QA services, taking full ownership of testing processes end-to-end. Rather than simply providing tools, we transform entire workflows—delivering results that were previously unattainable with any conventional approach. Transforming testing through people and technology, and turning quality into a competitive advantage—this journey has only just begun. We are now looking for those who will help us realize this transformation. Your work will redefine the standard for development teams around the world. | About This Role   Job Purpose Since its official release in October 2019, Autify has been implemented by numerous clients, and our client base is continuing to grow. While we provide all the essential functions required in a test automation platform, we continue to receive requests for new functions and improvements. Autify is working on growing the product further by adding new features. For this reason, we are expanding our engineering team to develop further and improve Autify’s highly reliable test execution mechanism. We are looking for a senior engineer to join our team.   You will mainly be responsible for the Japanese market requirement focused on developing and improving our new generation of AI platform products. You will also examine bug reports from customers, work on fixing them, and apply the findings when improving the core engine and architecture of the product. https://autify.jp/products/genesis   Responsibilities
