Mid-level Backend Engineer

The Backend Engineer will handle broad engineering work for SAMANSA, a short-film streaming VOD service. The product collects short films from around the world and delivers them through an app. The posting describes a viewing experience centered on short content and compares the intended user experience with TikTok. The role is part of a startup approaching its fifth year and is focused on developing a new entertainment service for a global business.

The stated required qualifications are at least two years of practical Ruby on Rails experience or equivalent experience, and the ability to work full-time. The introduction also refers to candidates with at least three years of practical experience, including people with relatively limited experience, so the posting contains both a three-year minimum description and a two-year Rails-specific requirement. No education requirement is stated.

Preferred experience includes 0-to-1 product or business development, UI/UX design, React development, Flutter development, and AWS. The named technical environment includes Flutter for mobile, HTML and CSS plus React and Next.js for the web frontend, AWS for infrastructure, and Ruby on Rails for the backend. GitHub is used for code management, while Notion and Slack are used for communication and management.

The company says the engineering team includes experienced engineers. It also describes members from the United States and many bilingual members, with overseas communication occurring depending on the work; some tasks can be performed only in Japanese.

The broader working-environment section describes a full flextime system, weekends and public holidays off, and a request for at least two office days per week regardless of employment type. The role-specific section instead states that employees come to the office once a week and work remotely on the other days. The posting also notes that some departments or roles may be fully remote. Online interviews are accepted. Applicants who pass document screening are expected to be contacted by the person in charge within one month.
