About the Role
Infrastructure Architect
Fixed-term contract (12 months), hybrid role (2–3 days per week).
The Customer is driving a strategic transformation to standardise substation compute infrastructure, moving from vendor-specific deployments to a centrally owned, secure, and scalable platform. The Infrastructure Architect will lead the design and implementation of this architecture, ensuring consistency, security, and scalability across different sites while supporting vendor-hosted applications.
Key Responsibilities
1. Architecture & Low-Level Design
- Develop Physical Technical Models (PTM) and Low-Level Designs (LLD), covering:
- Hardware specifications
- OS configurations and patching standards
- Security hardening baselines
- Produce implementation-ready design blueprints for engineering teams.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
2. Architecture to Engineering Alignment
- Bridge the gap between enterprise architects and engineering teams.
- Translate conceptual and logical designs into deployable, field-ready solutions.
- Ensure alignment between design intent and execution.
3. Infrastructure Standardisation
- Lead the transition from vendor-owned compute environments to Customer-owned standardised platforms.
- Define consistent build, configuration, and deployment standards.
- Enable vendor applications to operate efficiently on standardised infrastructure.
4. Scalable Deployment Framework
- Design a repeatable deployment model for rollouts across multiple sites.
- Ensure consistency, scalability, and minimal variation in deployments.
5. Thin Client & Access Architecture
- Architect standardised thin client/access solutions.
- Optimise for secure, efficient, and manageable application access.
6. PoC to Production Transition
- Convert proof-of-concept (PoC) learnings into production-ready, supportable solutions.
- Address gaps in resilience, supportability, and operational readiness.
7. Security, Compliance & Observability
- Ensure adherence to patching, hardening, and security standards.
- Integrate infrastructure with monitoring/observability platforms (e.g., Splunk).
- Align with regulatory and environmental compliance requirements.

Core Technical Skills
- Experience with hardened compute environments in critical infrastructure contexts.
- Expertise in:
- Virtualisation platforms (VMware / Hyper-V)
- Thin client / VDI solutions
- OS hardening and patch management
- Knowledge of high availability and redundancy protocols (e.g., PRP).
- Familiarity with monitoring/logging platforms (e.g., Splunk or similar).
- Ability to design for operational visibility and alerting.
Domain Experience (Preferred)
- Exposure to utilities, energy, or OT (Operational Technology) environments.
- Understanding of substation or industrial infrastructure constraints.
Key Competencies
- Strong ability to translate architecture into detailed engineering designs.
- Expertise in standardisation, scalability, and repeatable deployment patterns.
- Excellent collaboration across architecture, engineering, and operations teams.
- Strong technical documentation and communication skills.
Success Criteria
✅ High-quality PTM / LLD artefacts, ready for deployment. ✅ Establishment of a repeatable deployment architecture. ✅ Successful, low-variation rollout across multiple sites. ✅ Improved security posture, patch compliance, and manageability.
Role Significance
This role is critical to enabling the Customer’s transition to a standardised, secure, and centrally governed substation compute architecture, delivering: ✔ Higher operational efficiency ✔ Stronger security compliance ✔ Enhanced scalability across the infrastructure estate.
