Desirable

• We aim to design, build and provide scalable, secure, and stable infrastructure, while also enabling our engineers to quickly and easily deploy new code
• The Wealthsimple ecosystem is primarily Ruby on Rails and JavaScript micro services, with state backed by Aurora (PostgreSQL) and Redis
• The infrastructure-specific stack you will work on is powered by AWS, built by Ansible, deployed with Terraform, run on Red Hat Enterprise Linux, powered by Docker and Consul and finally, orchestrated by Nomad and “coming soon” Kubernetes
• Design, create, build, maintain and expand our infrastructure-as-code
• Design, create, build and maintain shared engineering resources for monitoring, alerting, logging, backups and disaster recovery for our AWS cloud environment
• Help guide our engineers in deploying scalable, resilient micro services that are in-line with our infrastructure's best practices, providing right-sizing, networking, security, and access-level suggestions
• Provide coaching and mentorship to engineering teams on designing, monitoring and integrating systems at scale
• Participate in an on-call rotation supporting underlying infrastructure, responding to incidents and supporting engineering teams as a second-line, when deeper subject matter expertise is required
• Assist in migrating all our microservices from Nomad to Kubernetes, further enhancing our infrastructure capabilities
