Summary
🤩
Rockstar🎓
Top SchoolAustin Seipp is a versatile software engineer with 18 years of experience focused on programming languages, compilers, cryptography, hardware design, and low-level systems. He is one of the rare commercial Haskell specialists, having used Haskell for nearly all of his recent projects and served as lead release engineer/maintainer for the Glasgow Haskell Compiler for roughly three years. His work spans FPGA/RTL design via the Clash compiler, distributed systems (notably contributions to FoundationDB), VLSI tooling, and security research, reflecting a comfort moving between high-level abstractions and silicon-near engineering. Austin is experienced in shepherding large open-source projects and communities, bringing both release-infrastructure and governance insight from roles like Haskell Prime committee membership. He combines deep technical craftsmanship with practical build/CI and packaging expertise, often addressing cross-platform build and performance issues that quietly accelerate developer velocity. Based in Austin, Texas, he’s open to interesting remote opportunities that leverage his unusual blend of formal methods, compiler internals, and hardware-software co-design.
