Senior Machine Learning Engineer, LLMs & Prompt Engineering Remote – Japan

Position: Senior Machine Learning Engineer, LLMs & Prompt Engineering (Permanent – Remote – Japan) An opportunity has come through our network for a Senior Machine Learning Engineer, LLMs & Prompt Engineering at Autify , a global software company specializing in AI-powered solutions that simplify identity verification and data extraction. This permanent position is fully remote within Japan , offering exceptional flexibility for talent residing anywhere in the country. The compensation ranges from ¥8M ~ ¥12M annually , and importantly, no Japanese language proficiency is required . Overseas applicants are welcome, and relocation support to Japan is available. You will mainly be responsible for developing a new product that leverages cutting-edge machine learning techniques and generative AI, guiding it from a proof of concept into a releasable product. Autify is known for its AI-powered software testing platforms like Autify Nexus and Autify Genesis (which generates test cases and test scripts from product documents), focusing on improving development productivity through test automation and efficiency. This role is a unique chance to contribute to the future of AI in software quality assurance. About the Position: Shaping AI-Powered Solutions for Software Testing As a Senior Machine Learning Engineer focusing on LLMs and Prompt Engineering, you’ll be at the forefront of developing innovative AI-powered solutions for the software testing industry. Your expertise will bridge the gap between advanced AI research and practical, impactful products. • Develop New Products Utilizing ML and Generative AI: You will be primarily responsible for developing a new product that meticulously utilizes machine learning techniques and generative AI . This involves taking a product idea from a nascent proof of concept (PoC) phase all the way through to a fully releasable product. Your work will directly shape the future offerings of Autify, leveraging cutting-edge AI for software quality assurance. • Create Effective Prompts for LLM Output Optimization: A crucial responsibility will be to create highly effective prompts to maximize the quality of the output from Large Language Models (LLMs). This requires a deep understanding of prompt engineering principles, iteratively refining prompts based on product specifications to achieve desired results, and ensuring the LLM’s responses are accurate, relevant, and useful for the software testing domain. • Build and Customize Machine Learning Models: You will actively build and customize machine learning models using data relevant to software testing, as needed for specific product functionalities. This involves data collection, preprocessing, model selection, training, and fine-tuning to ensure models perform optimally for tasks such as test case generation, bug detection, or anomaly identification. • Collaborate on Feature Implementation: You will work in close collaboration with other engineers, designers, and product leads to seamlessly implement various features within the new AI product. Throughout this process, you will consistently consider critical aspects such as performance (ensuring speed and efficiency), security (protecting data and systems), and reliability (guaranteeing continuous operation and accurate output). Your teamwork ensures holistic product development. • Create PoC Web/CLI Applications: You will proactively create Proof of Concept (PoC) Web/CLI (Command Line Interface) applications that utilize LLMs or ML models “under the hood” to validate the feasibility of new ideas. These rapid prototypes are essential for quickly testing concepts, gathering early feedback, and demonstrating the potential of AI-driven solutions before full-scale development. • Proactively Identify and Suggest Improvements: You will demonstrate a continuous improvement mindset by proactively identifying functions that can be improved within existing or new products. You will then strategically suggest possible solutions from both technical aspects (e.g., code optimization, new algorithms) and product-related ideas (e.g., new features, enhanced user experience), driving innovation from within. • Participate in On-Call Rotations: You will actively participate in on-call rotations for incident and… Apply tot his job
