Senior / Staff ML Ops Engineer

Waabi; Toronto; Presencial; CAD 140.000 - 190.000; Jornada completa

Descripción de la vacante

Waabi in Canada is seeking a senior ML infrastructure engineer to scale the training platform and developer experience for autonomous systems. You will design APIs/CLIs, manage cloud and on-cluster resources, and partner with researchers to ship reliable, scalable ML pipelines.

You will balance performance, reliability, and usability while driving tooling adoption and reproducibility in a fast-moving team focused on self-driving technology.

Formación

• 5+ years of software or infrastructure engineering, including ML or data-intensive production systems.
• Excellent Python, and a track record of designing APIs and CLIs other people enjoy using.
• Practical AWS depth: object storage at scale, IAM, GPU compute, networking, cost management, and IaC.
• Distributed training in PyTorch (DDP, FSDP, or similar), plus experiment tracking and model registry tooling.
• Fluency with containers, CI/CD, and modern build systems, including large monorepos.
• The ability to influence without authority: evaluate a framework on its merits and persuade teams.
• A collaborative default—co-own a system rather than defending a boundary.
• User empathy: fix the third-most-interesting problem blocking ten people.

Responsabilidades

• Build and evolve our training infrastructure on Kubernetes with GPU scheduling, autoscaling, and distributed jobs.
• Shape the developer-facing surface — CLIs, SDKs, and templates for teams to use.
• Shorten the inner loop: reduce time to first training run and improve iteration latency.
• Evangelize tooling with prototypes and migration paths for adoption.
• Strengthen the data and artifact layer with dataset versioning and high-throughput loading.
• Turn quick Python scripts into durable tooling with docs and observability.
• Make experiments legible with dashboards and a model registry across datasets to results.
• Ship CI/CD for models alongside autonomy and simulation.

You will..

• Build and evolve our training infrastructure on Kubernetes with Infrastructure — GPU scheduling, autoscaling, multi-node distributed jobs, capacity strategy, and the operators and workflow engines that keep long-running training reliable.
• Shape the developer-facing surface — CLIs, SDKs, job submission, templates, paved paths — designed with the teams who'll use them. Make the common case one command and keep the uncommon case possible.
• Shorten the inner loop. Time to first training run, edit-to-signal latency, local iteration before a job hits the cluster, fast failure over slow mystery. Measure it, publish it, drive it down.
• Evangelize best-in-class tooling and frameworks. Track what the ecosystem is shipping, evaluate honestly, and make the case with working prototypes and migration paths — or say plainly when a shiny thing isn't worth the switching cost.
• Strengthen the data and artifact layer. Dataset versioning, sharding, and high-throughput loading of large multimodal sensor data, so jobs saturate GPUs instead of waiting on I/O.
• Turn one-off Python into durable tooling — tested, documented, observable libraries, CLIs, and services with sane defaults, and deletions where they're overdue.
• Make experiments legible, with the teams who live in them: experiment hygiene, dashboards researchers trust, a real model registry, and lineage from dataset to checkpoint to simulation result.
• Ship CI/CD for models alongside autonomy and simulation, so a model change is validated the same way a code change is.
• Build observability across the ML stack — utilization, throughput, failure modes, queue times, cost per experiment. When a job fails at 3am on node 47, the researcher should find out why without you.
• Treat docs, onboarding, and support as product surface — golden-path guides, a new researcher productive on day two, office hours that turn repeat questions into shipped fixes.
• Drive adoption, not just availability. Prototype with real users, watch them work, iterate. A tool nobody adopts didn't ship.
• Make the platform boringly reliable — fewer failures, faster recovery, and none of the manual steps that quietly cost a team days.
• Build guardrails that don't feel like walls, with Security, IT, and Infrastructure: access controls, data handling, and cost governance that hold up in an IP-sensitive environment while staying self-serve.

Qualifications:

• 5+ years of software or infrastructure engineering, including tools or platforms used by other engineers and operating ML or data-intensive production systems.
• Excellent Python, and a track record of designing APIs and CLIs other people enjoy using.
• Practical AWS depth: object storage at scale, IAM, GPU compute, networking, cost management, and infrastructure as code (Terraform, Pulumi, or similar).
• Distributed training in PyTorch (DDP, FSDP, or similar), plus experiment tracking and model registry tooling — from the perspective of someone who made them pleasant for others to use.
• Fluency with containers, CI/CD, and modern build systems, including large monorepos.
• The ability to influence without authority: evaluate a framework on its merits, pilot it credibly, and persuade skeptical senior engineers to change how they work.
• A collaborative default — you'd rather co-own a system than draw a boundary around your part of it.
• User empathy: you'd rather fix the third-most-interesting problem blocking ten people than the most interesting one blocking nobody.
• Strong product instincts, strong writing, and comfort operating autonomously in ambiguous territory.
• Passionate about self-driving technologies and frontier AI, and about what a small, world-class team can do with the right infrastructure.

Bonus/nice to have:

• Internal developer platform, research platform, or DevEx work — with a story about a tool whose adoption you grew from zero.
• Large-scale distributed GPU training: hundreds to thousands of accelerators, NCCL, high-performance cluster networking, collective communication tuning.
• High-throughput loading of LiDAR or camera data, and formats such as Parquet or WebDataset.
• Workflow and scheduling systems — Argo Workflows, Ray, Flyte, Kubeflow, or Slurm.
• Build-system depth (Bazel or similar), including remote caching in a monorepo.
• Simulation infrastructure or large-scale batch evaluation pipelines.
• Background in ML, robotics, or autonomous systems infrastructure.
• Security-and IP-sensitive production environments.
• Open-source contributions to ML infrastructure or developer tools.
