We are a climate-tech product team building a multi-tenant SaaS platform. We are scaling into enterprise customers and want an experienced architect to help us design the platform for that next stage.

This is a focused, well-scoped engagement with clear goals, not an open-ended retainer. You will work directly with the project lead.

What you will do

• Design multi-tenant resource isolation so workloads stay predictable as customer count and data volume grow.
• Architect the async and background-processing model for long-running, data-heavy operations.
• Design and implement high availability for the data tier, including replication and verified backup and restore.
• Mature the deployment pipeline for deterministic, auditable releases.
• Define the service-level indicators that reflect real customer experience, and build the observability to measure them.
• Right-size cloud resources against measured usage and introduce autoscaling.
• Load and capacity testing at realistic data volumes.
• Give us your long-term view on cloud strategy. We are on Azure and are not planning to migrate, but we want an architect's assessment to plan against.

What we are looking for

• 5+ years in cloud architecture, platform engineering or SRE, with real design ownership on at least one production system.
• Multi-tenant SaaS experience. You have solved noisy-neighbour and tenant-isolation problems before and have views on how.
• Strong production Kubernetes: Helm, resource management, autoscaling, disruption budgets, rolling-update strategy.
• Azure preferred, ideally AKS. Equivalent depth on AWS or GCP is fine.
• MongoDB operations at production scale: replication, migrations, backup and restore verification.
• Prometheus, Grafana, Alertmanager, Loki. Able to design meaningful alerting, not just install exporters.
• Terraform and CI/CD pipeline design.
• Able to read Node.js well enough to reason about where memory and time go.
• Comfortable disagreeing with a proposed design and explaining why.
• English sufficient for written technical discussion and calls.

Nice to have

• GitOps in production (Argo CD or Flux).
• Load testing with k6 or JMeter.
• Exposure to blockchain infrastructure or carbon markets. Genuinely optional, we will teach the domain.
