Reporting to the Vice President Product Development the Senior Cloud Architect will lead the modernization of a portfolio of VM-based enterprise applications into a unified cloud-oriented platform that combines VMs containers FaaS/serverless and a modern data layer optimized for time-series workloads (including migration from Oracle to PostgreSQL) with clear KPIs for performance stability and availability.

The Senior Cloud Architect defines the target cloud architecture and roadmap to evolve from fragmented VM-centric applications and Oracle databases to a cohesive platform built on modern cloud services PostgreSQL-based data stores and well-defined service-level objectives. The role partners with product engineering security and operations to design govern and guide implementation of a resilient secure observable and costefficient cloud platform.

This is a hybrid role based in our Burnaby BC office.

Specifically the Senior Cloud Architect will:
Assess the current application integration and infrastructure landscape (VMs Oracle databases data flows) and define a target-state architecture and phased modernization roadmap (rehost replatform refactor consolidate).
AWS Lambda Azure Functions Google Cloud Functions).
Core cloud services for networking storage identity observability and security.
Define patterns and standards for containerization and serverless: image baselines configuration and secret management service discovery event-driven integration (queues streams event buses storage triggers) and clear guidance on when to use containers vs FaaS vs VMs.
Modernize the data layer by planning and executing migration of core transactional and time-series workloads from Oracle to PostgreSQL or managed PostgreSQL services ensuring performance reliability and manageable cutovers.
Design data architectures optimized for time-series data (e.g. PostgreSQL with extensions such as TimescaleDB or similar) including ingestion retention partitioning downsampling and analytics for AMI transformer and network telemetry.
Define and oversee database migration strategies (schema conversion ETL/ELT pipelines dual-write/read phases validation cutover and rollback) for Oracle PostgreSQL in close collaboration with application and analytics teams.
Define service-level objectives (SLOs) SLIs and KPIs for performance stability and availability across platform services and customer-facing applications (e.g. latency error rates uptime throughput time-to-recover).
Work with SRE/operations teams to implement monitoring alerting and dashboards aligned to these KPIs and use the metrics to drive capacity planning performance tuning and reduction of incidents over time.
Establish and enforce cloud governance and security baselines including IAM/RBAC models network segmentation encryption backup/DR and compliance-aligned configurations.
Collaborate with DevOps/SRE/platform engineering teams to implement infrastructure as code (e.g. Terraform CloudFormation/Bicep) CI/CD pipelines and observability (logging metrics tracing) for VM container and FaaS workloads.
Optimize cloud cost and performance through right-sizing autoscaling strategies use of managed services and lifecycle policies with clear KPIs for platform efficiency.
Produce and maintain architectural documentation reference diagrams and standards; communicate trade-offs and decisions effectively to technical and business stakeholders.

7 years of experience designing and implementing cloud architectures for enterprise applications including deep experience with at least one major public cloud (AWS Azure or GCP).

• Strong understanding of cloud networking security identity and data architectures (VPC/VNet design IAM/RBAC encryption and key management messaging/streaming data stores).
• Hands-on experience with infrastructure as code and CI/CD and working closely with DevOps/SRE/platform teams to operate production workloads.
• Experience with relational databases and practical exposure to PostgreSQL in production environments.
• Strong communication skills to translate business goals into architectural blueprints and influence cross-functional teams.

Experience in utilities energy or other regulated/mission-critical industries with awareness of reliability compliance and data residency requirements.
Demonstrated experience leading database modernization projects including Oracle-to-PostgreSQL migrations and adoption of PostgreSQL-based solutions for time-series or IoT data.
Experience defining and implementing reliability and performance KPIs/SLOs (including error budgets) and using them to guide architectural choices and trade-offs between speed and stability.
Background in platform engineering or internal developer platforms building reusable shared services and self-service capabilities for product teams.
