| Role | Required | Description |
|---|---|---|
| Compiler Engineer | Knows basic DSL design concepts for compiler engineering and can apply them in common tasks. Uses standard tools and follows established team practices. Understands when and why this approach is used. | |
| Language Tooling Engineer | Understands DSL grammar specifications and basic parser construction. Writes simple DSL expressions following existing language syntax. Tests DSL programs against expected output under mentorship. | |
| Systems Programmer (C/C++) | Uses internal DSLs for configuration and build system specifications. Understands the difference between internal and external DSLs. Modifies simple DSL scripts following established patterns and documentation. |
| Role | Required | Description |
|---|---|---|
| Compiler Engineer | Confidently applies DSL design for compiler engineering in non-standard tasks. Independently selects optimal approach and tools. Analyzes trade-offs and suggests improvements to existing solutions. | |
| Language Tooling Engineer | Designs and implements domain-specific languages with custom parsers and semantic analysis. Builds error reporting and IDE integration for DSL tooling. Writes comprehensive test suites covering DSL edge cases and error handling. | |
| Systems Programmer (C/C++) | Implements embedded DSLs for hardware description and system configuration tasks. Builds DSL interpreters with proper scoping, type checking, and error reporting. Writes compiler tests ensuring DSL-to-native code translation correctness. |
| Role | Required | Description |
|---|---|---|
| Compiler Engineer | Expertly applies DSL design for compiler engineering in designing complex systems. Optimizes existing solutions and prevents architectural mistakes. Conducts code reviews and trains colleagues on best practices. | |
| Language Tooling Engineer | Required | Architects DSL ecosystems with composable grammars, type systems, and compilation targets. Designs language server protocols for DSL IDE support. Mentors the team on language design principles and user experience trade-offs. |
| Systems Programmer (C/C++) | Required | Designs DSLs for performance-critical domains such as networking rules and memory management policies. Architects DSL compilation to optimized native code with zero-overhead abstractions. Mentors engineers on language design for systems programming contexts. |
