Stockholm, SwedenEntry Level
Responsibilities
- Design and implement a new BEAM instruction for consuming intermediate terms without fully materializing them.
- Add a compiler pass to the BEAM SSA pipeline to identify suitable producer–consumer patterns.
- Use existing alias and sharing analyses and the compiler’s destructive-update optimization.
- Compile the Erlang/OTP codebase with the optimization enabled and measure its applicability and target patterns.
- Extend the compiler test suite to verify that the transformation is safe and correct.
- Implement the runtime mechanism in the BEAM interpreter to reclaim intermediate heap space while terms are consumed.
- Evaluate the optimization’s performance and memory impact.
Requirements
- Currently pursuing a master’s degree in computer science or a similar field.
- Interest in compilers, programming-language implementation, or language runtimes.
- Programming experience and willingness to work with Erlang and C.
- Ability to understand and modify an existing compiler and runtime system.
- Interest in program analysis, memory management, and performance evaluation.
- Familiarity with SSA-based optimization or garbage collection is helpful but not required.
- Careful attention to correctness, testing, and experimental methodology.
Benefits
- Opportunity to work on compiler analysis, runtime implementation, and empirical evaluation at Ericsson.
- Opportunity to contribute to solutions addressing challenging systems problems within a diverse and inclusive team.
- Location: Stockholm, Sweden.
