Senior Software Engineer, Platform Engineering
Hybrid · Mississauga, Ontario, Canada
Job Summary
Senior Platform Engineer to design, build, and maintain platform services, APIs, SDKs, and internal tools used across engineering teams. Own platform services end-to-end—from design and implementation through production operation and continuous improvement—writing high-quality, testable code. Improve CI/CD workflows and developer automation with a focus on usability and efficiency. Apply distributed systems and backend engineering principles to design scalable, resilient services and APIs. Take production ownership of the services and tools you build, including observability, debugging, and incident response. Role centers on TypeScript/Node.js, Kubernetes, Terraform/Pulumi, CI/CD, IaC, GitOps, and developer tooling; hybrid work setup with in-office collaboration in Mississauga, Canada.
Required Qualifications
- Expert-level proficiency in TypeScript/Node.js building production-grade APIs, services, developer tools, and developer-facing UIs (React or similar) with strong automated testing practices (unit, integration, E2E)
- Strong software engineering fundamentals — distributed systems, API design, and production backend services, with a proven ability to make pragmatic trade-offs across scalability, reliability, and developer experience
- Working proficiency with observability (metrics, logging, distributed tracing, SLI/SLO frameworks) and production ownership of services you build — including incident response and post-mortems
- Strong proficiency with Kubernetes — building software abstractions and APIs, extending capabilities through custom controllers and operators
- Strong proficiency designing and building CI/CD pipelines optimized for security, compliance, and developer experience
- Working proficiency with Infrastructure as Code (Terraform, Pulumi), GitOps practices, and cloud-native environments
- Strong communication, influence, and documentation skills — able to drive adoption of platform patterns, translate technical complexity for diverse audiences, and produce ADRs, runbooks, and developer- facing documentation
