Job description

e23 WP. Kuala Lumpur, Federal Territory of Kuala Lumpur, Malaysia

e23 is a Malaysian technology venture builder focused on developing blockchain and digital asset infrastructure that bridges traditional finance and decentralized finance (DeFi).

e23’s mission is to advance Malaysia’s participation in the digital financial ecosystem by creating compliant, transparent, and institution‑grade blockchain systems.
