About this role
A Senior Backend Engineer (IC/tech lead) role at a company that, since 2019, has provided online marketplaces for energy businesses and grown into Japan's largest trading market, with corporate participants (including major power companies) accounting for 95% share and gross transaction value approaching 3 trillion yen, targeting a 100-trillion-yen annual market. Following a Series B extension raising 5.05 billion yen, the company is investing in the development team for global-standard feature development, security and AI. Its products include an energy trading platform (a licensed online trading platform), a market-data platform (power and fuel price/market data), a market-risk-management tool (energy trading risk management), and an environmental-value trading marketplace (domestic environmental value and overseas voluntary credits toward carbon neutrality). As the system scales, this senior backend role tackles large-scale architecture challenges. Based in Minami-Aoyama, Minato-ku, Tokyo; remote work available (onboarding may require office attendance). Full-time.
