Compiler Developer (Entry Level)

Ericsson • Austin, TX

1d • $107,350 - $118,650

About The Position

As a Full-Time AI Compiler Engineer, you will own the end-to-end observability and optimization pipeline for 5G/6G workloads. You will build the infrastructure that translates high-level JAX/StableHLO graphs into cycle-accurate, memory-optimized object code for Ericsson’s proprietary Many-Core Architecture (EMCA).

Requirements

• Bachelors or Masters degree in Computer Science
• Compiler Expertise: Strong understanding of the LLVM/MLIR ecosystem (Dialects, Lowering, TableGen).
• Systems Mastery: Proficiency in C++ and Python; experience with low-level systems programming (no MMU/virtual memory environments).
• Performance Engineering: Deep knowledge of tracing and profiling (e.g., Perf, eBPF, or custom instrumentation) and cycle-accurate simulation.
• Math & AI: Familiarity with JAX, StableHLO, and XLA; understanding of quantization techniques (4-bit/8-bit) and operator fusion.
• Architecture: Solid grasp of multi-core computer architecture, specifically memory hierarchy and data-path optimization.

Responsibilities

• MLIR Pipeline Development: Design and implement custom MLIR passes for static memory management.
• Advanced Profiler Architecture: Lead the development of a "Shift-Left" profiler that provides compile-time visibility and inter-core synchronization bottlenecks.
• Hardware-in-the-Loop Validation: Integrate the compiler output with the Bait test infrastructure to validate functional equivalence between single-core and multi-core partitioned workloads.
• Tooling Sovereignty: Develop high-performance CLI and TUI tools for system developers to visualize IR transformations and hardware utilization in real-time.
• Cross-Functional Alignment: Act as the technical bridge between Ericsson research artifacts and the production environment, ensuring stable interface contracts.

Benefits

• Ericsson offers excellent health benefits including the choice of three medical plan options and a dental plan option that allow an employee to select the level of coverage that suits their needs. Employees will receive company credits in an amount equal to the cost that Ericsson pays toward the cost of their medical and dental premiums for themselves and eligible covered dependents.
• The Ericsson US 401(k) Plan offers an automatic 3% company contribution and Ericsson match $1 for every $1 you put into the 401(k) Plan on the first 3% of your eligible pay, plus 50 cents on every $1 on the next 2% of eligible pay. When you contribute at least 5% of eligible pay, you are receiving Ericsson’s full matching contributions of 4%. Matching and company automatic contributions stop when your total eligible pay for the year reaches the IRS limits. Employees will also receive company credits in an amount equal to the cost of basic life insurance and basic accidental death and dismemberment coverage, as well as short-term and long-term disability coverage. Employees also have the option to participate in Ericsson’s Stock Purchase Plan.
• New employees are provided a minimum of 15 days of accrued vacation, up to 3 personal days per year, 11 annual holidays, 8 hours of volunteer time, and 80 hours of sick time annually.
