WHO ARE WE LOOKING FOR?

We are looking for a visionary and deeply technical LLM Engineer to pioneer the future of software development in the Automotive industry. You are an expert in the AI agent space who is not just content with using existing tools but is driven to invent the specialized agents that will revolutionize our Software Development Life Cycle (SDLC). You’ll be at the heart of our mission to reduce feature delivery times from 12 months to 2 weeks by designing the Requirements, Design, Coding, and Testing agents that will form our collaborative AI workforce. You are an R&D-focused builder who can turn the ambitious goal of a fully orchestrated, AI-assisted development process into the functional foundation of the Automotive ecosystem's future.

RESPONSIBILITIES

• Spearhead the research and development of specialized LLM based agents for each stage of the SDLC, including Requirement Analysis, Design, Code Generation, and Automated Testing.
• Design, prototype, and refine the core logic for the Agent Orchestrator, defining how context, artifacts, and human approvals flow between agents in the development pipeline.
• Develop novel prompting strategies and agent tool-chains that produce reliable, structured outputs (e.g., specification documents, test plans, pull requests) for complex software engineering tasks.
• Partner with platform engineers to define the requirements for the underlying platform, ensuring it supports advanced agentic concepts like human-in-the-loop workflows within an IDE and asynchronous reviews via GitHub.
• Prototype the next generation of developer experiences, including tight integration of AI agents within VS Code for real-time coding and testing collaboration.
• Own the core AI quality metrics for each agent, defining benchmarks for "time saved per task" and "rate of accepted changes" to continuously improve their performance.

Requirements

MINIMUM QUALIFICATIONS

• Proven experience designing and building LLM-powered agents and multi-step agentic workflows, especially for code generation or analysis.
• Demonstrated ability to design prompts that yield reliable, structured JSON or other structured data formats from LLMs.
• 4+ years of professional software engineering experience, with strong proficiency in Python and hands-on experience coding AI-native tools and applications.
• Experience working within large-scale enterprise environments and developing for Platform as a Service (PaaS) models.

NICE TO HAVES

• Experience architecting and building developer tools, IDE extensions (e.g., for VS Code), or GitHub Apps.
• Experience with context engineering using technologies such as MCP servers, knowledge bases and tool registries.
• Published research or open-source contributions in the field of AI agents, especially for software engineering.
• Experience with Google's Agent-to-Agent (A2A) protocol or similar inter-agent communication standards.
• Familiarity with the challenges of software development in the automotive industry.
• Professional fluency in Japanese, both written and spoken.
