Senior DSL Engineer

The role

You will design and implement a domain-specific language and compiler toolchain for programming machine learning models. The role focuses on the compiler frontend, including scanning, parsing, AST design, type and shape inference, and error reporting.

What you will do

• Design and implement compiler frontend components including the lexer, parser, abstract syntax tree, and compiler passes.
• Design and implement type inference and shape inference systems for the DSL.
• Design clear, actionable error and warning diagnostics.
• Work within and extend a proprietary automatic reference counting system.
• Participate in code reviews.
• Collaborate through pair programming sessions.
• Contribute to the full software engineering lifecycle.
• Help inform the design of future DSLs.

Required qualifications

• BS degree in Computer Science, Computer Engineering, or equivalent practical experience
• Extensive experience designing and implementing domain-specific languages.
• Deep expertise in compiler frontend engineering: lexical analysis, parsing, AST design, semantic analysis, and compiler passes.
• Strong experience with type inference and shape inference systems.
• Strong professional C++ background with modern C++ standards.
• Deep understanding of automatic reference counting concepts and object lifetime management in C++, including familiarity with shared_ptr, weak_ptr, and unique_ptr.
• Experience designing compiler diagnostics (errors and warnings).
• Experience across the full software engineering lifecycle: product specification, requirements gathering, high-level design, low-level design, implementation, and testing.
• General familiarity with GPUs or other accelerator devices and their role in high-performance computing and machine learning workloads.

Nice to have

• Master's or PhD in Computer Science, Computer Engineering, or equivalent
• Experience with or willingness to use AI-assisted code generation tools in day-to-day development.
• Familiarity with PyTorch or similar machine learning frameworks.
• Experience with Python language internals or strategies for subsetting Python-like languages.
