Senior Enterprise Architect – Cloud, Infrastructure & SAP to provide strategic and technical leadership across a complex enterprise technology landscape

We are seeking a Senior Enterprise Architect – Cloud, Infrastructure & SAP to provide strategic and technical leadership across a complex enterprise technology landscape. This individual will be responsible for defining and governing architecture across Microsoft Azure, AWS, SAP, enterprise infrastructure, networking, security, data centres, and edge environments.

The ideal candidate brings deep enterprise architecture experience within Oil & Gas, Energy, or Utilities and has successfully designed and modernized large-scale hybrid and multi-cloud environments. This role requires a strong combination of strategic architecture leadership and hands-on technical expertise.

Project Duration - 1 year

Key Responsibilities

- Hybrid Cloud Strategy: Architect and govern scalable, resilient, and cost-optimized multi-cloud infrastructure environments leveraging both Microsoft Azure (e.g., Azure Energy Data Services) and Amazon Web Services (AWS).
- SAP Enterprise Integration: Drive the long-term architectural roadmap for the SAP landscape (SAP ECC, S/4HANA- Central Finance), ensuring seamless data orchestration and integration between core ERP, field logistics, and cloud-native applications.
- Infrastructure Landscape Modernization: Evaluate and optimize the end-to-end infrastructure landscape, seamlessly bridging traditional corporate data centres with edge computing, remote field networks, and public cloud environments.
- Rigorous Security Architecture: Partner with the CISO team to imbed zero-trust security architectures across IT/OT environments, protecting critical infrastructure against cyber threats while ensuring compliance with global energy regulations and NIST/ISO standards.
- Governance & Standards: Establish enterprise-wide architectural guardrails, reference models, and deployment patterns specifically for cloud migration, SAP integrations, and infrastructure connectivity.

Must Haves

- Cloud Platform Mastery: Extensive, hands-on architectural experience with Azure and AWS ecosystem services, preferably backed by professional-level certifications (e.g., Azure Solutions Architect Expert, AWS Certified Solutions Architect Professional).
- SAP Ecosystem Expertise: Proven track record designing enterprise architectures that incorporate complex SAP environments, including integration middleware, migration strategies, and data archiving.
- Infrastructure & Network Architecture: Deep understanding of modern infrastructure landscapes,



including software-defined networking (SDN), hybrid cloud connectivity (ExpressRoute, Direct Connect), edge computing, and high-availability systems.
- Enterprise Security Standards: Comprehensive knowledge of security principles including identity & access management (IAM), data encryption at rest/in transit, network segmentation, and vulnerability management within critical infrastructure sectors.
- Industry Experience: 10+ years in IT/Enterprise Architecture, with a substantial portion spent managing large-scale infrastructure environments in the Oil & Gas, Energy, or Utilities sector.
- Preferred Certifications (e.g., TOGAF, CISSP, SAP Certified Enterprise Architect

Ideal Candidate The successful candidate will be a senior-level architect who can operate at both the strategic and technical level. They will be comfortable defining enterprise-wide architecture direction while also engaging deeply with engineering, cloud, infrastructure, SAP, networking, and cybersecurity teams to ensure solutions are practical, secure, scalable, and aligned with the organization’s long-term technology strategy.
