Lead AI and optimisation projects from customer problems and experiments to production, guide technical decisions and reviews, and coordinate delivery teams.
About this role
HEROZ is hiring an LLM application engineer to turn AI into practical enterprise services. The focus is applications built with LLMs rather than developing the underlying models.
Responsibilities cover specifications, data-flow and application architecture, development and testing of agents and RAG services, framework selection, and production fixes and enhancements. Services may run in the cloud or on premises. The engineer works with an EM on progress, task assignment and reviews; some projects may use other AI or optimisation techniques.
Applicants need professional cloud-web application architecture experience, web-software development skills and regular use of generative AI for coding, tests or documentation. Prior LLM-application work is explicitly unnecessary. Annual pay is JPY 6–8.5 million. Remote work requires approval, and grade determines discretionary work or flexitime; flexitime includes twenty fixed overtime hours with additional payment above that amount.
