Mid Software Engineer | Remote First Selling Points<ul><li> <What's In It For You?> Work from Anywhere in Japan: Embrace a truly remote-first culture-engineers typically visit the Tokyo office just once a month (if at all). Enjoy the freedom to design your work-life balance, whether you're in Tokyo or elsewhere in Japan. Must be in Japan. No Japanese Required: English is the language of collaboration. You'll work in a diverse, international team where your skills-not your language ability-open the door to exciting projects. Impact at Scale: Your code will help drive payment infrastructure for some of the world's most recognized online brands. You'll be building systems that support thousands of merchants as they expand into new markets-proof that this company is both stable and scaling fast. Career Growth in a Thriving Environment: The company is planning to triple in size over the next few years, offering you the chance to grow with the business and take on new challenges as they emerge. Startup Agility, Established Foundation: Experience the best of both worlds-move fast, take ownership, and innovate in a company that has already proven its business model and product-market fit. Learning & Development: Receive up financial support for books, courses and conferences. Take advantage of language lessons and regular internal tech events to keep your skills sharp. Generous Time Off: Over 20 days of paid leave per year, including seasonal and birthday holidays, so you can recharge and pursue your passions outside of work. Inclusive, Flat Culture: Engineers play a key role in both product and technical decisions. You'll have a real voice and the autonomy to shape your own growth path.</li></ul> Company Profile<ul><li>Join a globally recognized tech innovator in Tokyo that's redefining digital payments for the world's most dynamic brands.
