I’m working with a venture-backed AI infrastructure startup building a compiler and runtime platform designed to improve accelerator efficiency and give developers greater flexibility over where their workloads run.
They’re looking for a Compiler Optimization Engineer to shape the part of the compiler that turns model structure into better execution.
The opportunity You’ll work between model import and target code generation, making decisions about how computations are represented, transformed and prepared for execution.
Your work will include: Developing graph transformations that reduce redundant work and unnecessary data movement.
Improving fusion decisions and how tensor layouts propagate through a program.
Evolving the IR and pass pipeline as new model patterns emerge.
Using hardware measurements to identify missed optimisation opportunities.
Working with frontend and backend engineers to keep compiler interfaces clear.




Building validation that protects correctness as optimisations become more ambitious.
What would make you a strong fit Strong C++ and practical experience developing compiler transformations or IRs.
A clear understanding of dataflow, optimisation legality and performance tradeoffs.
The ability to connect graph and layout decisions with memory behaviour on accelerators.
Experience with MLIR, XLA, affine or polyhedral analysis, or ML framework internals would be particularly relevant.
The appeal is substantial technical ownership: your decisions will influence how models are compiled and how effectively they use different hardware. You’ll join an experienced compiler and systems team, with equity participation and room to develop recent approaches.
