Full-Stack Engineer Average Annual Income Ranking: 15th (¥9.54 million)

The average monthly rate for full-stack engineer jobs is ¥795,000, translating to an average annual income of ¥9.54 million. This places full-stack engineers at 15th in the IT job category salary rankings.

Full-stack engineers are responsible for a wide range of development areas, including front-end, back-end, databases, and infrastructure. Due to their ability to handle multiple technical domains, demand is high. However, their rates are lower compared to roles like IT consultants or PMOs, which involve overall business decision-making and management, resulting in a 15th-place ranking.

Despite the 15th position, the average annual income of ¥9.54 million is considered high. Demand is strong in web services, SaaS, and startups. Engineers with broad development experience are expected to maintain stable market value in the future.

Full-Stack Engineer Job Volume Ranking: 11th (3.23%)

As of July 2026, full-stack engineer jobs account for 3.23% of the total freelance market, ranking 11th by job volume, with an average monthly rate of ¥795,000.

Full-stack engineers handle a broad range of responsibilities, from front-end and back-end development to databases and infrastructure. Their ability to work across multiple development areas makes them highly valued in development teams, and their job share remains at a stable level.

Going forward, as development efficiency improves and small-team projects become more common, demand for full-stack engineers is expected to continue. In particular, web services, SaaS, and startups—where engineers often handle diverse responsibilities—are expected to drive demand.

Remote Work Ratio for Full-Stack Engineer Jobs
