Senior Software Engineer, Platform (Remote within Canada)

Job Description This is a remote position. The Role Our products increasingly depend on data-intensive APIs that power not just a reporting platform, but also dedicated, per-customer environments where AI agents execute tasks, maintain customer-specific state, and run proactive analyses. Today, these environments run as containerized workloads on a major cloud provider, with a growing layer of application code responsible for everything from core functionality to routine lifecycle operations. We’re looking for a senior engineer who thrives at the intersection of product engineering and infrastructure. This is not a traditional DevOps or SRE position. The majority of your time will be spent writing application code that controls infrastructure primitives: messaging and queue abstractions, compute lifecycle management, data persistence and migration, container orchestration and updates, zero-downtime deployments, bootstrap and provisioning logic, permissions models, observability hooks, and security boundaries. The ideal candidate is comfortable diving deep into Linux internals, container runtimes, networking, and storage—but approaches problems with a product engineer’s mindset: shipping reliable, maintainable systems, choosing pragmatic abstractions, and making complex runtime behavior feel routine to internal and external consumers alike. Technology environment: Modern JavaScript/TypeScript runtime, React, document and search databases, major cloud platform (Azure), and infrastructure-as-code via Pulumi. What You’ll Do Build and evolve the systems that provision, update, secure, and observe isolated agent execution environments. Design reusable abstractions around queues, locks, background job processing, and service-bus mechanics so product engineers can build on solid primitives. Extend and refine the infrastructure-as-code foundation (Pulumi), establishing patterns other teams adopt. Work directly with Linux systems, persistent storage, OS-level disks, container boundaries, permission models, logging pipelines, and runtime debugging. Operate within a small, high-ownership, cross-functional team running weekly delivery cycles. Requirements Ideal Background 6+ years of software engineering experience, with meaningful time spent deep in infrastructure, platform, or systems engineering. Strong production backend experience. TypeScript/Node.js is a plus, but engineering judgment and ability to ramp on the stack quickly matter more. Deep, hands-on cloud experience. Our primary environment is Azure, but strong fundamentals on AWS or GCP transfer readily. Fluency with infrastructure-as-code. Pulumi is our tool; Terraform, CDK, or similar experience is fully applicable. Hands-on container and runtime expertise. Docker is essential; exposure to Kubernetes, Nomad, ECS, Docker Swarm, or comparable orchestration systems is helpful but not required. Experience designing reliable systems around background jobs, queues, locks, service buses, migrations, retries, and failure recovery. Strong security instincts applied to application runtime environments. You’ll Thrive Here If… You’re genuinely excited by infrastructure problems. When something breaks, you want to understand the system mechanics, not just restart and scale. You have a strong ownership bias: you make decisions, stand behind them, and move fast to fix things when they go wrong. You’re pragmatic—you can ship the simple solution when speed matters, while flagging what needs to evolve later. You’re comfortable in a fast-moving, ambiguous environment where the “right way” isn’t handed to you; you help define it. You enjoy being a strong individual contributor and a supportive teammate. Engineering is a team sport. Traditional office access, plus structured team gatherings every two months and an annual company-wide retreat. Benefits What We Offer Competitive compensation with equity for all employees, comprehensive health benefits from day one, a monthly wellness/lifestyle stipend, 20 days of PTO, and a $1,500 home-office stipend. Remote-first across Canada, the U.S., and beyond, with optional access to physical hub offices in four major cities. Strong product-market fit, rapid growth, experienced founders with prior successful exits, and significant Series B funding backing the roadmap. High-impact role where early team members directly shape product direction, technical architecture, and company trajectory. Collaborative, low-ego culture recognized as a top Canadian software employer. Team Connection Virtual day-to-day: An AI-enhanced virtual workspace that enables spontaneous collaboration, quick syncs, and a “live” digital HQ feel. In-person: Optional office access, plus structured team gatherings every two months and an annual company-wide retreat.
