Backend Compiler Engineer for AI Accelerators

Acceler8; United States; On-site; USD 140,000 - 220,000; Full time

Job summary

Acceler8 Talent is seeking a Compiler Engineer to build hardware-close compiler backends for a specialized AI accelerator. You will translate model graphs into executable code, reason about IR transformations and lowerings, and ensure performance on custom hardware.

This role collaborates across architecture, runtime, and model teams in a production environment. The ideal candidate brings deep compiler fundamentals, C++ expertise, and hands-on ownership of compiler components, with experience in

Qualifications

• Proven ownership of compiler backends and IR transformation passes.
• Strong fundamentals in compilers, graph reasoning and C++ software engineering.
• Ability to explain how compiler decisions affect memory use, scheduling and device performance.
• Experience delivering substantial compiler components and debugging complex technical issues.
• Understanding of compiler IR representations, transformation legality, dependencies and graph-to-execution mapping.
• Ability to make backend design decisions independently with clear reasoning.
• Experience using tests, debugging and workload results to validate compiler changes beyond API integration.

Responsibilities

• Design and deliver compiler backend components, including IR transformations, lowering and code generation.
• Map graph and model computation onto the execution capabilities and constraints of specialized hardware.
• Reason about memory behavior, scheduling and data movement when making compiler design decisions.
• Debug correctness and performance issues across compiler, runtime and hardware interfaces.
• Evaluate changes through real workloads and device execution, connecting implementation choices to measured results.
• Collaborate across the accelerator stack as the architecture and software platform evolve.
• Design IR representations and transformation logic that preserve program meaning while exposing hardware constraints.
• Implement lowering and code-generation paths, mapping computations and dependencies to the target execution model.
• Investigate how compiler choices affect intermediate storage, data movement and scheduling with architecture/runtime teams.
• Build focused tests and workload-level checks to detect miscompilations and regressions.
• Trace problems from model/graph inputs through compiler to runtime and device behavior.
