Original job description

The short version - Canada Quant Labs is hiring an AI Engineer to own pieces of our train → quantize → deploy pipeline. You'll ship open-weight checkpoints (like our Hy3, GLM-5.2, and DeepSeek-V4 quants), build the eval harnesses that prove they hold up, and serve them through vLLM. Full-time, hybrid in Victoria, BC. CAD $140,000–$190,000 + equity.

The role

We're Canada's open-weight model lab: we train, quantize, and deploy sovereign AI on Canadian Blackwell silicon for the industries - legal, medical, defence, finance - that can't run on someone else's API. Everything we ship is public: weights, recipes, benchmarks, and the engineering log of what broke along the way.

This is a hands-on engineering role on the model team, not a research-caretaker role. The person in it trains models, breaks them, measures them, and ships them - then writes up what happened so the community doesn't have to re-walk the dead-ends.

What you'll do

Train and fine-tune open-weight models on our DGX B300 cluster - domain distills, reasoning and agentic post-training, and Canadian-corpora adaptations for legal, medical, defence, and finance buyers.
Own quantization recipes end-to-end - W4A16 and NVFP4 with llm-compressor, calibration-data selection, and quality validation against the FP8/BF16 references.
Build and run the eval harnesses that decide what ships: reasoning, instruction-following, long-context retrieval, and domain benchmarks like our CanLegal Bench, whose leaderboard is now live.
Serve what you ship through vLLM - speculative decoding (MTP), expert-parallel MoE serving, throughput/latency profiling, and the kernel-level debugging when numbers don't make sense.
Publish everything - model cards, reproducible recipes, benchmark methodology, and engineering logs - and upstream fixes to the open stack (vLLM, llm-compressor) when you find them.

What you bring

Strong PyTorch and transformer fundamentals. You've trained or fine-tuned multi-billion-parameter models and can reason about what's happening inside the network - not just drive the framework.
Real LLM serving or quantization experience. You've shipped something with vLLM, TensorRT-LLM, SGLang, or similar - or you've built quant/serving tooling (GPTQ, AWQ, NVFP4, activation-aware recipes) that other people used.
Systems instincts. Comfortable reading CUDA/perf profiles, reasoning about memory footprints and tensor/expert parallelism, and hunting a 13% throughput regression down to a kernel flag.
Evidence of craft. A checkpoint, a kernel, an eval harness, a merged PR, a write-up - something public we can look at. We hire from artifacts, not credentials.
Clear technical writing. Our work is open by default; your model cards and engineering logs are part of the product.

Nice to have

MoE training or serving experience (expert parallelism, router behaviour, sparse-attention variants).
Speculative decoding - MTP/EAGLE-style draft heads, acceptance-rate tuning.
Eval science: benchmark design, contamination hygiene, statistical rigour about run-to-run noise.
Background in a regulated domain (legal, medical, defence, finance) or with Canadian data-residency constraints.
Open-source maintainership or a meaningful contribution history in the inference/training stack.

How we work

Small team, hybrid in Victoria, BC - we like being in the room for design reviews and launch days, and we don't count hours the rest of the time. Compute is dedicated, not queued: experiments start when you're ready. Decisions get written down, results get published, and the person who did the work presents it.

Compensation & logistics

Posted per BC pay-transparency requirements. We hire for impact; exceptional candidates can exceed the range. Base salary CAD $140,000–$190,000 Equity Meaningful early-stage grant Location Victoria, BC

How to apply

Apply below - a short note and your résumé are all we need. Links to artifacts (Hugging Face, GitHub, papers, benchmarks, write-ups) help a lot.

We read every application and reply within two weeks. The process: intro call → technical deep-dive on something you've built → paid half-day work trial on real cluster work → offer.
