[Hiring] Senior Cloud Architect @Heirs Technologies

Role Description

The Senior Cloud Architect is the strategic owner of the platform's cloud infrastructure design — the person who decides how compute, networking, storage, and managed services are structured, connected, and governed across a dual-cloud environment at continental scale. Working under the Enterprise Architect and providing technical leadership to the Cloud Engineers, you will define the cloud architecture patterns, standards, and reference designs that the entire platform is built on. Where the Cloud Engineers own the build and operation, you own the blueprint — and on a platform serving millions of Africans, that blueprint must be resilient, secure, and built to last.

What You'll Do

• Cloud Architecture & Strategy:
  • Define and own the platform's dual-cloud architecture strategy across AWS and Azure.
  • Set structural principles, service selection standards, and governance frameworks.
  • Ensure architecture scales from 15 million to hundreds of millions of users.
  • Avoid single points of failure for the platform.
• Multi-Cloud & Active-Active Design:
  • Own the architectural design of the platform's multi-cloud strategy.
  • Define traffic distribution and failover execution between AWS and Azure.
  • Design global traffic management architecture.
  • Specify cross-cloud connectivity, routing, and health-check standards.
• Reference Architecture & Standards:
  • Produce and maintain clear reference architectures for cloud infrastructure patterns.
  • Define architectural decision records (ADRs) for significant technology choices.
  • Ensure engineering teams have architectural clarity.
• Network Architecture Design:
  • Define high-level network architecture across both cloud environments.
  • Provide clear network design to Network & Security Engineers.
• Security Architecture:
  • Define cloud security architecture including IAM patterns and encryption standards.
  • Work with the Platform Manager (Security) to meet PCI DSS and data protection requirements.
• Container & Serverless Architecture:
  • Define container and serverless architecture including Kubernetes platform design.
  • Ensure support for zero-downtime deployments and full observability.
• Technology Governance & Service Catalogue:
  • Own the platform's approved cloud service catalogue.
  • Evaluate new managed services against platform requirements.
• FinOps & Cost Architecture:
  • Design cloud infrastructure for cost efficiency.
  • Work with the Platform Manager on cloud cost governance.
• Observability Architecture:
  • Define observability architecture including standards for logging and metrics collection.
  • Ensure visibility into every layer of the infrastructure.
• Technical Leadership & Architecture Review:
  • Provide technical leadership and architectural guidance to Cloud Engineers.
  • Participate in the platform's architecture review process.

Qualifications

• 8+ years of cloud infrastructure experience, with at least 3 years in a cloud architecture role.
• Deep expertise across both AWS and Azure.
• Demonstrated experience designing multi-cloud or multi-region architectures.
• Strong cloud security architecture knowledge.
• Expert-level knowledge of cloud networking architecture.
• Proven ability to produce clear architectural documentation.
• AWS Certified Solutions Architect – Professional (SAP-C02) — required.
• Microsoft Certified: Azure Solutions Architect Expert (AZ-305) — required.

Requirements

• Experience designing container platform architecture at scale.
• FinOps practitioner experience.
• Experience in fintech, banking, or a regulated cloud environment.
• Familiarity with service mesh architecture.
• Experience with Infrastructure as Code at the architectural level.

Benefits

• Impactful work — design the cloud architecture of a platform built to serve hundreds of millions of Africans.
• World-class team — work alongside architects, engineers, and security specialists.
• Modern ways of working — architecture-led, cloud-native, and built on a dual-cloud foundation.
• Lagos, Nigeria — based at our Lagos office, at the heart of Africa's most dynamic technology ecosystem.
