Senior Site Reliability Engineer

About the Role Before an autonomous vehicle navigates a busy intersection, before a robot learns to pick and place in a warehouse, before any Physical AI system is trusted in the real world, it has to prove itself in ours. Parallel Domain builds the platform that validates the next generation of autonomous systems in high‑fidelity virtual environments, and the infrastructure underneath that platform is what makes simulation at scale possible.

We're hiring a Senior Site Reliability Engineer to help build and operate that infrastructure. This role sits at the core of how we run large‑scale, distributed simulation workloads for autonomous‑systems testing and validation. You'll work across multi‑region AWS infrastructure, operate Kubernetes at scale, and contribute directly to reliability, security, and deployment systems that the rest of the engineering org depends on.

This is a hands‑on role with the broad ownership typical of a startup. You'll partner closely with platform, simulation, and ML teams to keep the system running smoothly and evolving. We're growing the team—two of these roles are open—and the work is substantive: multi‑region GPU scheduling, Windows workloads on Kubernetes, large‑scale batch simulation, and an enterprise product direction that will require rethinking parts of how we deploy and operate.

Responsibilities

Infrastructure ownership and cloud operations.

Design, build, and maintain multi‑region AWS infrastructure using Terraform. Operate and scale EKS clusters across production regions: autoscaling, node lifecycle, and workload health. Manage networking across environments: VPC design, DNS, load balancing, and cross‑region connectivity. Support infrastructure changes, migrations, and expansions into new regions. Contribute to and improve GitOps‑based deployment workflows using GitHub Actions, Helm, and Kustomize.

Reliability engineering and incident response.

Build and run incident management processes: severity definitions, escalation paths, and on‑call practices. Lead incident response, debugging, and root‑cause analysis. Write postmortems and drive systemic reliability improvements. Improve observability across metrics, logging, tracing, and dashboards. Support GPU and batch workloads running on Kubernetes.

Security and access management.

Provide security‑conscious feedback on platform architecture decisions. Own cloud IAM governance: roles, policies, and access boundaries across accounts and services. Lead compliance‑adjacent work including audit‑readiness, partner certification requirements, and responses to customer security questionnaires.

Platform tooling and developer experience.

Improve CI/CD pipelines and infrastructure validation. Support engineers with infrastructure debugging, environment setup, and performance issues. Contribute to tooling and automation in Python and Bash. Take on adjacent responsibilities as needed in a startup environment.

Required Qualifications

Experience.

5+ years in SRE, DevOps, or infrastructure engineering roles, with a track record of operating production systems across multiple regions.

Terraform.

Modules, state management, and multi‑environment patterns.

AWS depth.

Solid experience across VPC, IAM, EKS, S3, and CloudWatch.

Kubernetes expertise.

Cluster operations, autoscaling, RBAC, and Helm.

CI/CD and GitOps.

Experience with GitHub Actions, ArgoCD, or similar workflows.

Networking fundamentals.

CIDR, DNS, load balancing, VPN, and cross‑region connectivity.

Observability.

Experience with tooling such as Prometheus and Grafana.

Scripting.

Comfort with Python and Bash for tooling and automation.

Cross‑platform familiarity.

Working knowledge of both Linux and Windows environments. Operational experience supporting Windows‑based workloads is a meaningful advantage.

Pragmatism and ownership.

Comfortable in a fast‑moving startup with evolving priorities. You take ownership of systems while collaborating closely with other teams, and you're pragmatic about tradeoffs between speed, reliability, and complexity.

Preferred Qualifications

Windows on Kubernetes.

Experience with Windows node pools, Windows AMIs, and GPU‑adjacent components on K8s.

GPU scheduling.

Familiarity with GPU scheduling on Kubernetes, including NVIDIA device plugin configuration.

Domain workloads.

Experience supporting simulation, ML, or rendering workloads in cloud infrastructure.

AWS extras.

Exposure to AWS Storage Gateway, Active Directory integrations, or AWS Transfer Family.

Service mesh.

Familiarity with service proxy or service mesh patterns.

Container OS.

Experience with container‑optimized OS images (e.g., Bottlerocket, Packer).

Cost optimization.

Cloud cost optimization at scale.

What Makes a Great Candidate You think in failure modes and proactively surface issues. You hold a principled view on security and push back constructively when designs introduce unnecessary risk. You communicate clearly across engineering, product, and customer‑facing teams, flagging issues with urgency proportional to customer impact. You take end‑to‑end ownership of complex efforts and know when to push for the clean solution versus the pragmatic one.

Base salary range of CAD $145,000–$185,000, depending on skills, qualifications, and experience, plus equity, full health/dental/vision coverage, learning stipend, and generous vacation. This role is remote‑friendly across Canada and the US Pacific Northwest.
