Remote Machine Learning Compiler Engineer - Gensyn (Basé à London)

The world will be unrecognisable in 5 years.

Machine learning models are driving our cars, testing our eyesight, detecting our cancer, giving sight to the blind, giving speech to the mute, and dictating what we consume, enjoy, and think. These AI systems are already an integral part of our lives and will shape our future as a species.

Soon, we'll conjure unlimited content: from never-ending TV series (where we’re the main character) to personalised tutors that are infinitely patient and leave no student behind. We’ll augment our memories with foundation models—individually tailored to us through RLHF and connected directly to our thoughts via Brain-Machine Interfaces—blurring the lines between organic and machine intelligence and ushering in the next generation of human development.

This future demands immense, globally accessible, uncensorable, computational power. Gensyn is the machine learning compute protocol that translates machine learning compute into an always-on commodity resource—outside of centralised control and as ubiquitous as electricity—accelerating AI progress and ensuring that this revolutionary technology is accessible to all of humanity through a free market.

Our Principles:

AUTONOMY

• Don’t ask for permission - we have a constraint culture, not a permission culture.
• Claim ownership of any work stream and set its goals/deadlines, rather than waiting to be assigned work or relying on job specs.
• Push & pull context on your work rather than waiting for information from others and assuming people know what you’re doing.
• No middle managers - we don’t (and will likely never) have middle managers.

FOCUS

• Small team - misalignment and politics scale super-linearly with team size. Small protocol teams rival much larger traditional teams.
• Thin protocol - build and design thinly.
• Reject waste - guard the company’s time, rather than wasting it in meetings without clear purpose/focus, or bikeshedding.

REJECT MEDIOCRITY

• Give direct feedback to everyone immediately rather than avoiding unpopularity, expecting things to improve naturally, or trading short-term pain for extreme long-term pain.
• Embrace an extreme learning rate rather than assuming limits to your ability/knowledge.

Responsibilities:

Lower deep learning graphs—from common frameworks (PyTorch, TensorFlow, Keras, etc.) down to an IR representation for training—with particular focus on ensuring reproducibility.

Write novel algorithms for transforming intermediate representations of compute graphs between different operator representations.

Ownership of two of the following compiler areas:

• Front-end - handle the handshaking of common Deep Learning Frameworks with Gensyn's IR for internal IR usage. Write transformation passes in ONNX to alter IR for middle-end consumption.
• Middle-end - write compiler passes for training-based compute graphs, integrate reproducible Deep Learning kernels into the code generation stage, and debug compilation passes and transformations as you go.
• Back-end - lower IR from middle-end to GPU target machine code.

Minimum Requirements:

Compiler knowledge—base-level understanding of a traditional compiler (LLVM, GCC) and graph traversals required for writing code for such a compiler.

Solid software engineering skills—practicing software engineer, having significantly contributed to/shipped production code.

Understanding of parallel programming—specifically as it pertains to GPUs.

Strong willingness to learn Rust—as a Rust by default company, we require everyone to learn Rust so that they can work across the entire codebase.

Ability to operate on:

• High-Level IR/Clang/LLVM up to middle-end optimization; and/or
• Low Level IR/LLVM targets/target-specific optimizations—particularly GPU-specific optimizations.

Highly self-motivated with excellent verbal and written communication skills.

Comfortable working in an applied research environment—with extremely high autonomy.

Nice to haves:

Architecture understanding—full understanding of a computer architecture specialized for training NN graphs (Intel Xeon CPU, GPUs, TPUs, custom accelerators).

Rust experience—systems level programming experience in Rust.

Open-source contributions to Compiler Stacks.

Compilation understanding—strong understanding of compilation in regards to one or more High-Performance Computer architectures (CPU, GPU, custom accelerator, or a heterogeneous system of all such components).

Proven technical foundation—in CPU and GPU architectures, numeric libraries, and modular software design.

Deep Learning understanding—both in terms of recent architecture trends + fundamentals of how training works, and experience with machine learning frameworks and their internals (e.g., PyTorch, TensorFlow, scikit-learn, etc.).

Exposure to Deep Learning Compiler frameworks—e.g., TVM, MLIR, TensorComprehensions, Triton, JAX.

Kernel Experience—experience writing and optimizing highly-performant GPU kernels.

Note:For potential candidates outside these criteria, we still encourage you to apply as there may be openings with higher/lower levels than listed above.

Compensation / Benefits:

Competitive salary + share of equity and token pool.

Fully remote work—we hire between the West Coast (PT) and Central Europe (CET) time zones.

4x all expenses paid company retreats around the world, per year.

Whatever equipment you need.

️Paid sick leave.

Private health, vision, and dental insurance—including spouse/dependents.
