Significant senior solution architecture experience gained in a large, complex enterprise environment, ideally within financial services or another highly regulated industry.

Proven experience operating as a Principal Architect, Lead Solution Architect or senior architecture leader with accountability for complex domain architecture outcomes.

Proven ability to lead architects while staying hands-on and close to solution design, technology decisions, architecture trade-offs and delivery execution.

Strong experience working with established architecture frameworks such as TOGAF or equivalent.

Advanced stakeholder management and influencing capability, supported by strategic thinking and systems-level problem solving.

Exceptional communication skills, with the ability to translate complex technical concepts for executive, business, delivery and engineering audiences.

A pragmatic, outcomes-focused approach to decision-making, balancing risk, cost, value, compliance and delivery realities through collaboration.

Deep senior solution architecture subject matter expertise across Human Resources, People Technology, workforce, talent, payroll, learning, employee experience and related corporate domains.

Strong understanding of modern HR technology ecosystems, business processes, employee lifecycle journeys, workforce data flows, integration patterns and platform dependencies.

Experience architecting solutions across enterprise People platforms such as Oracle HCM, Workday, SAP SuccessFactors or equivalent HR technology platforms.

Practical understanding of workforce data, employee lifecycle processes, identity and access management, privacy obligations and security requirements associated with enterprise People systems.

Proven ability to partner directly with HR and People leaders to shape technology strategy, prioritise investment and deliver measurable business outcomes.

Demonstrated experience architecting and implementing Data & AI-enabled solutions in enterprise environments, moving beyond proof-of-concept into scalable, production-grade delivery.

Strong understanding of Data & AI platforms, frameworks and tooling, including machine learning platforms, GenAI services, MLOps pipelines, model lifecycle management and enterprise integration patterns.

Proven experience designing best-practice Data & AI architectures, including data pipelines, model deployment patterns, observability, security, governance and responsible AI considerations.

Hands-on experience guiding teams through Data & AI solution design, implementation trade-offs and integration into existing enterprise platforms.

Strong awareness of Data & AI risk, compliance, privacy and security requirements, with the ability to embed these into architecture standards and reference designs.

Experience uplifting team capability in Data & AI engineering, architecture patterns and modern delivery practices to build sustainable long-term capability.

The ideal candidate is a technology leader who remains close to the technology. You’re equally comfortable engaging executive stakeholders on investment strategy, reviewing architecture options, challenging solution designs and guiding teams through complex implementation trade-offs.

You bring deep HR domain architecture credibility built through delivering complex enterprise solutions across People Technology ecosystems.
