[Hiring] Senior Software Engineer, Platform @Calliere

Role Description

This is a remote position.

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
• 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
• 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)
• 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.

Qualifications

• 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.

Requirements

• 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.

Benefits

• Competitive compensation with equity for all employees.
• Comprehensive health benefits from day one.
• A monthly wellness/lifestyle stipend.
• 20 days of PTO.
• 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.

Company Description

• 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.
