Sr. Software Engineer - AI Compiler & Runtime Infrastructure

Sr. Software Engineer - AI Compiler & Runtime InfrastructureJob Location: San Jose, CA or Irvine, CA - open to hybrid Compensation: $190K - $260K base DOE plus equityOur company is a venture-backed fabless semiconductor company building the next generation of autonomous compute silicon optimized for real-time, physical AI. We develop high-performance processors and software that enable deterministic, low-latency execution for converged sensing, communications, and AI tasks - addressing limitations of conventional CPU, GPU, and FPGA architectures.

We are looking for a hands-on, experienced engineer to lead development of our AI compiler stack and runtime infrastructure. You will help architect, implement, and optimize compiler passes, schedulers, and runtime systems that translate high-level programs into high-performance code for our custom hardware.This role is a perfect fit for engineers who thrive on systems-level challenges - including compiler internals, runtime design, optimization, and tooling - and want to make a direct impact on how tomorrow's real-time systems are built.Key ResponsibilitiesDesign and implement core compiler components (IR transformations, optimization passes, backend codegen).Build and optimize runtime systems, including task schedulers, resource managers, and execution engines.Collaborate closely with hardware architects to define ABI, scheduling strategies, and performance targets.Diagnose performance issues using profiling and benchmarking tools; propose and implement improvements.Take ownership of features end-to-end - from design through validation and documentation.Influence long-term compiler and runtime architecture.Lead design reviews and technical discussions.Mentor and guide other engineers on best practices in systems programming and compiler design.QualificationsBachelor's or Master's degree in Computer Science, Computer Engineering, or a related field.7+ years of software engineering experience with significant work in compilers and/or runtime systems.Expert in C/C++ (Python for tooling and automation a plus).Deep understanding of compiler internals (IR, passes, optimizations, codegen).Strong runtime and scheduler design experience.Proven ability to ship production-quality systems software with measurable impact.PreferredHands-on experience with MLIR, IREE, LLVM, or similar compiler frameworks.Experience designing schedulers and execution systems for accelerators.Familiarity with profiling tools and performance analysis.OSS contributions or publications in relevant areas.BenefitsVacation/PTOEquityMedicalDentalVisionLife Insurance401kFlexible hybrid work modelProfessional development supportFor this position you must be currently authorized to work in the United States.
