Startup Company Compensation

At startup companies, compensation varies significantly depending on the company’s growth stage.

While the average salary is 4.92 million yen, startups typically offer stock options and performance-based incentives, which can lead to substantial income increases depending on the company’s growth.

Freelance Engineer Income

For freelance senior engineers, monthly rates are set according to skills and track record. According to a survey by Relance targeting freelance engineers, the average annual revenue (income) is approximately 5.76 million yen.

While income ranges vary considerably depending on project rates, achieving an annual income of 10 million yen or more is feasible when securing high-rate projects.

Global Market Salary Comparison

A significant gap still exists between engineer salaries in Japan and other countries.

According to a 2022 survey by Human Resocia, influenced by recent yen depreciation and dollar appreciation, Japan ranks 20th globally.

Switzerland ranks first, followed by the United States in second place and Israel in third, with European countries notably showing high annual salaries and compensation levels.

However, with the rise of remote work, opportunities to earn global-level salaries while working in Japan have increased, as more engineers work for overseas companies.

2. Factors Affecting Compensation

Multiple factors determine senior engineer salary levels.

Technical skills, years of experience, company size, and location have the most significant impact. Let’s explore how these factors influence compensation.

Required Technical Skills and Experience

The most crucial factors determining senior software engineer compensation are technical skills and years of experience.

Advanced skills in cloud architecture design, microservice architecture design and implementation, machine learning/AI technologies, blockchain technology, and security design/implementation are particularly important elements leading to higher compensation.

Regarding experience-based compensation, salaries typically increase with years of experience.

However, the value of experiences gained during those years is considered more important than simple tenure.

Salary Differences by Company Size and Region

Company size and location significantly impact salary levels.

Large IT companies (1000+ employees) typically offer 8 million yen or more, mid-sized IT companies (100-999 employees) offer around 5-6 million yen, and small IT companies (fewer than 100 employees) typically start at 4 million yen.

Regionally, there’s little difference between Tokyo’s 23 wards and major metropolitan areas like Osaka and Nagoya. However, other designated cities and regional cities typically offer 70-80% of Tokyo’s baseline salary (considering Tokyo as 100%).

Remote Work’s Impact on Regional Differences

The rise of remote work is gradually reducing regional salary disparities.

Particularly for engineers with high expertise, cases of earning metropolitan-level salaries while living in regional areas are increasing.

3. Career Paths for Increasing Annual Income

Stock Option Programs

Stock options are rights to purchase company shares. Typically, units are granted according to position and contribution level, with gradual vesting being common.

Exercise prices are set by companies based on fair market value at the time of grant, and exercise periods are similarly company-defined, so careful review is important.

Particularly in startup companies, potential profits could reach tens of millions of yen at exit, making this an attractive program for both public companies and those planning to go public.

Remote Work and Flexible Work Arrangements

Modern senior engineers enjoy highly flexible working arrangements. Full remote work allows working from anywhere in Japan, and an increasing number of companies enable working while living abroad.

Hybrid work typically requires office attendance 1-2 times per week or only for important meetings.
