Sumio Kiyooka is a Technical Program Manager with over two decades of software and professional services experience, blending hands-on full-stack development with program leadership across startups and enterprise vendors. He has led consulting teams and solution architecture efforts, shipped deployments at dozens of companies, and navigated acquisitions most recently as part of Memfault’s integration into Nordic Semiconductor.

He thrives working independently in remote settings while building rapport with stakeholders, and brings uncommon breadth—from low-level networking and on‑prem operations to product-focused UX and training.
