About the job

As a Site Reliability Engineer II on the Serving Platforms team within Infrastructure Engineering, you will design, automate, and manage the core container stack powering global, business-critical applications. Operating across high-scale, self-hosted environments, you will serve as a subject matter expert for Kubernetes, Linux systems, and cloud-native automation to drive platform reliability, security, and performance. You will partner with globally distributed engineering teams to deliver greenfield infrastructure projects, triage complex system-level incidents, and expand self-service tooling for developers. This role plays a foundational part in scaling infrastructure resilience to support next-generation workloads and AI platform services.

Responsibilities

• Maintain, tune, and ensure high availability for low-level Linux operating systems and Kubernetes control planes across self-hosted bare-metal infrastructure.
• Architect, build, and maintain scalable container management, configuration management, and automation tooling across global environments.
• Investigate, resolve, and conduct root-cause analysis for complex infrastructure disruptions and performance bottlenecks at the system call level.
• Collaborate with distributed engineering teams to design and implement infrastructure standardization and platform engineering initiatives.
• Participate in the team on-call rotation to support critical production systems and maintain operational resilience.
• Develop self-service tools, automation pipelines, and infrastructure observability to eliminate operational toil and streamline developer workflows.

Minimum Qualifications

• 3+ years of professional experience in systems engineering or site reliability engineering supporting production Linux environments (e.g., Ubuntu, CentOS).
• Demonstrated experience building, operating, and troubleshooting bare-metal Kubernetes clusters, including control plane, etcd, and CNI plugin management.
• 2+ years of experience with configuration management tools such as Ansible, Puppet, Chef, or SaltStack in production settings.
• Proficiency in scripting and systems automation using languages such as Go, Python, or Bash.
• Hands-on experience responding to live production incidents, conducting root-cause analysis, and supporting distributed systems or messaging platforms.

Preferred Qualifications

• Experience operating, scaling, and monitoring AI/ML workloads or model serving platforms in high-concurrency production environments.
• Hands-on expertise with public cloud infrastructure (AWS, GCP, or Azure) and containerized CI/CD pipelines (e.g., Docker, GitHub Actions, Jenkins).
• Familiarity with distributed key-value stores (e.g., Consul, etcd, Redis) and enterprise telemetry systems (e.g., Prometheus, Grafana).
• Working knowledge of virtualization platforms (e.g., Proxmox, VMware, KVM) and low-level Linux networking (e.g., iptables/nftables, routing, load balancing).
• Experience creating OS-level packages (RPM/DEB) and contributing to open-source or globally distributed infrastructure projects.

This posting is for an existing vacancy.

The best connections happen face-to-face, whether you’re sitting down to dinner or having coffee with a coworker. That’s why OpenTable has adopted a hybrid workplace model. This role aligns with that approach, with an expectation of coming into the office two days a week—giving employees the best of both worlds: in-person collaboration and flexibility.

The expected range of compensation for this position based in Toronto, Canada, including commission and/or bonuses, is $110,000-$130,000 CAD. There are a variety of factors that go into determining a compensation range, including but not limited to external market benchmark data, geographic location, and years of experience sought/required.

We offer a competitive base salary and benefits including: health benefits, retirement benefits; life insurance; paid time off (including PTO, paid sick leave, medical leave, bereavement leave, floating holidays and paid holidays); and parental leave benefits. This role is eligible to be considered for an annual bonus and equity grant.

Work Environment & Flexibility

At OpenTable, we pride ourselves on fostering a global and dynamic work environment. As a team member with us, you will benefit from a schedule tailored to accommodate a global workforce operating across multiple time zones. While the majority of your responsibilities may align with conventional business hours, there will be instances where you are expected to manage communications - via calls, Slack messages, or emails - outside of regular working hours to effectively collaborate with international colleagues, respond to restaurant partners, and/or address urgent matters. OpenTable will always abide by and consider local laws and regulations.

Inclusion

We’re committed to creating a workplace where everyone feels they belong and can thrive. We know the best ideas come when we bring different voices to the table, so we're building a team as dynamic as the diners and restaurants we serve—and fostering a culture where everyone feels welcome to be themselves.

If you need accommodations during the application or interview process, or on the job, we’re here to support you. Please reach out to your recruiter to request any accommodations.
