Sr. Software Engineer - AI Compiler & Runtime Infrastructure

Our 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., * Design 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.

• Bachelor’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.

Preferred

• Hands-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.
