Principal Compiler Engineer at Stealth Startup
New York, New York, United States
Summary
🤩
RockstarStefan Teleman is a Principal Compiler Engineer based in New York with over 7 years of focused experience building compilers, toolchains, and high-performance system software across Linux, Solaris, FreeBSD, Android and embedded targets. He has led compiler and FPGA efforts at startups and research labs and shipped production-grade work on LLVM/clang, GCC, Binutils, GDB, MLIR, TVM and CUDA—specializing in backend codegen, loop/vector optimizations, SIMD, and platform-specific tuning for ARM64, RISC-V, SPARC and PPC64. Stefan’s background spans quantum and AI inference compilers, real-time systems, and supercomputing toolchains, and he prefers 100% remote roles outside finance and crypto. Known for pragmatic performance analysis and microbenchmark-driven optimization, he also brings low-level assembler expertise and a long-standing commitment to open systems and FOSS toolchains. An unexpected detail: he once quipped that learning FORTRAN is a rite of passage—“Any half-decent programmer can write FORTRAN in any language”—reflecting deep historical and practical grounding in scientific computing.
