Summary
👤
Senior🎓
Top SchoolMark Jen is a versatile software engineer with eight years of experience building and operating large-scale infrastructure and AI systems from founding stages to hyperscale. He has deep systems and language breadth—Go, Python, C/C++, Ruby, iOS/Objective-C and more—and has run and orchestrated A100/H100/H200 supercomputing clusters for production ML workloads. As a founder and CTO he designed hybrid fiber/wireless SDN and shipped kernel-level networking on commodity hardware, and he later helped take a low-level fine-tuning API (Tinker) from zero to one at a startup. Currently at Meta working at the intersection of AI and infrastructure, he blends hands-on engineering with operational responsibility for cutting-edge execution environments. Based in San Francisco, he combines product instincts from multiple founder and leadership roles with a curious-dev mindset that favors shipping pragmatic, performant systems. An offbeat detail: his early career includes product and management roles spanning Microsoft, Google (Associate PM with a famous blogging exit), and Plaxo, giving him rare cross-functional fluency.
