Job description

We are seeking an expert Senior Cloud Application Specialist to lead the technical design, full-cycle programming, and pipeline automation of highly secure, scalable, cloud-native enterprise solutions. In this role, you will take technical ownership of translating architectural specifications into production-ready web and multi-tier systems. Operating at the modern intersection of distributed cloud frameworks, automation engineering, and infrastructure-as-code, you will write custom code to orchestrate network dependencies, integrate secure delivery pipelines, and optimize runtime performance across complex virtual systems.

Location: Toronto, ON (Fully Onsite, 7.25 hours per day between 8:00 AM and 5:00 PM)

Duration: 15-month contract.

Advantages

• Advanced DevSecOps Blueprinting: Own the end-to-end design of modern pipelines, embedding automated compliance and security tooling directly into cloud workflows.
• Core Network Automation Impact: Eliminate traditional system bottlenecks by replacing manual networking setups with innovative, API-driven programmatic code.
• Multi-Tier Stack Horizon: Expand your engineering footprint across premium container orchestration engines and modern distributed storage layers.
• Extended Contract Runway: Gain long-term professional stability with a 15-month technical project lifecycle focused on core infrastructure innovation.

Responsibilities

• Cloud Application Engineering: Facilitate the development, design, construction, testing, and implementation of high-availability web-based, multi-tier, and cloud-hosted applications.
• Infrastructure Automation & Orchestration: Write robust code to interact directly with RESTful APIs to automate network provisioning processes, such as dynamic IP address assignment and DNS configuration management.
• DevSecOps Pipeline Design: Design, develop, and deploy end-to-end continuous integration and continuous delivery (CI/CD) pipelines embedded with automated security guardrails.
• Platform Customization & Integration: Engineer software platform foundations to run seamlessly across virtual environments, integrating a blend of cloud systems and Open Source Software (OSS) products.
• System Optimization & Fine-Tuning: Analyze, evaluate, and fine-tune software applications post-production to maximize processing speeds, upgrade interfaces, and correct performance constraints.
• Quality Assurance & Walkthroughs: Author low-level technical specifications, implementation plans, test criteria, and unit-testing matrices while actively leading cross-functional design and code walkthrough sessions.
• Tier-3 Operational Support: Diagnose, isolate, and troubleshoot complex production incidents and codebase defects, providing rapid response and mitigation strategies to customer issues.
• Technical Analytics & Status Telemetry: Track and deliver structured weekly progress metrics, system dependency updates, and operational risk summaries to project leadership.
• Knowledge Transfer & Mentorship: Provide structured knowledge-transfer sessions, system walkthroughs, and technical documentation to core internal staff to support ongoing platform sustainability.

Qualifications

• Core Engineering Seniority: Minimum of 8-10+ years of progressive, hands-on professional experience in cloud application development, technical systems engineering, and full-lifecycle software delivery.
• Microsoft Azure Specialization: Demonstrated recent technical expertise architecting and supporting Microsoft Azure core services (App Services, Azure Functions, and Azure Kubernetes Service - AKS).
• Containerization & Clustering Mastery: Strong professional capability configuring, deploying, and managing containerized multi-tier workloads utilizing Docker, Kubernetes, or OpenShift.
• Advanced Pipeline Automation Toolkit: Proven experience constructing, automating, and optimizing secure, end-to-end CI/CD pipelines using enterprise tools such as Azure DevOps, Jenkins, Ansible, or equivalent orchestration suites.
• API Integration Acumen: Direct, practical experience writing backend application code to interface with RESTful APIs for automated infrastructure management (e.g., automated IP and DNS allocation).
• Enterprise Cloud Governance Depth: Solid functional understanding of cloud landing zones, identity and access management (IAM), data encryption keys, and observability frameworks (monitoring, telemetry, and structured logging).
• Programming Framework Competency: Deep proficiency in at least one major programming language suited for data engineering or cloud application workflows (e.g., Python, C#, or Java) paired with solid relational database skills.
• Virtualization & Hypervisor Literacy: Strong practical working knowledge of hypervisors, hardware-to-software interfaces, network topologies, and virtualization techniques.
• Soft Skills: Outstanding problem-solving capacities, structural visualization skills, and clear verbal and written communication mechanics, with a track record of meeting tight deadlines independently and collaboratively.
