Position: Senior Database Engineer – Seoul, South Korea

At DNK, we’re transforming how real estate is managed across APAC. Our AI-driven, end-to-end platform empowers property owners, managers, and investors to eliminate inefficiencies, unify operations, and unlock new value across their portfolios.

This isn’t just another PropTech platform. DNK replaces fragmented systems and limited tech adoption with a single, unified solution that blends global best practices with deep local expertise, helping teams operate smarter at scale.

At the core of our platform is Investment Manager, an intuitive system designed to analyze and manage large-scale real estate portfolios. Supporting both residential and commercial assets, it consolidates data into a single source of truth: enabling transparent performance tracking, smarter decision-making, enhanced reporting, and improved operational efficiency.

Founded in 2020, DNK today manages over US$4.5 billion in assets across APAC, with offices in Tokyo and Seoul. As we continue to scale, the systems we build, and the people who build them, play a critical role in shaping the future of real estate management across the region.
