Engineer Intern

Role overview Join a long-term engineering internship building customer-facing web applications, business systems, and an in-house software product. You will own assigned features from design through implementation and testing, using coding agents while personally reviewing and improving their output. The role also includes refining development workflows so the team can deliver more reliably.

Responsibilities - Develop features across front ends, APIs, and databases for web applications and business systems. - Use coding agents to implement, test, and refactor software, checking the results yourself. - Improve agent-assisted workflows through project guidance, reusable skills, hooks, verification scripts, and automation. - Write tests, participate in code reviews, and document design decisions. - Clarify uncertain requirements with questions and proposals, then deliver agreed work to deadlines.

Requirements - Current undergraduate or graduate student in any year. - Availability at least four days per week for a minimum of one year. - Experience designing and building a web application with a coding agent; provide a repository or public project URL. - Fundamentals in TypeScript or Python, with the ability to inspect, verify, and fix generated code. - Ability to resolve ambiguity through communication and deliver work on time.

Nice to have - Experience improving coding-agent setups, such as project instructions, skills, hooks, or subagents. - Experience with React, Next.js, Google Cloud Platform, or AWS. - Built automation for repetitive work that other people have adopted. - Hackathon projects, open-source contributions, technical writing, or talks.

Benefits and work setup - Flexible hours, with at least four working days per week, for a term of at least one year. - Remote work or an office option in Daikanyama. - Hourly pay of ¥1,500–¥2,500.
