We are looking for a technically exceptional Integration Architect to join the Digital & Technology team at Compass Group UK & Ireland. You'll combine strong judgement with a practical, delivery-minded approach - evaluating platforms and approaches, shaping integration patterns that engineers can build to, and driving targeted modernisation where it will reduce risk and improve reliability. This is a role for someone who is comfortable producing technically rigorous architecture, and able to explain options, trade-offs, and roadmaps to senior stakeholders when required.

If you are the kind of Integration Architect who is energised by complexity, motivated by the opportunity to build something that genuinely matters, and ready to leave a lasting mark on how a large organisation connects and operates - this is the role for you.

About Compass Group UK & Ireland

Our colleagues serve customers every day across thousands of locations, from schools and hospitals to stadiums, offices and visitor attractions. Digital & Technology (D&T) is around 260 people and is driving the business's AI First strategy.

Integration Architect - The role

Integration is the connective tissue of our technology estate. It influences how quickly we can deliver change, how reliably our systems operate, and how effectively our platforms - from SAP to e-commerce to our data estate - work together to serve the business and our customers. Getting this right is a key enabler for delivery and operational performance.

The Integration Architect is a key domain expert within Digital & Technology, sitting at the intersection of architecture and engineering. The role partners closely with delivery teams building products, the architecture community shaping technology direction, and programmes across commerce, data, and SAP to ensure integrations are designed consistently, securely, and in a way that will scale.

Key Responsibilities

Integration Strategy and Platform Direction

• Lead the development of the integration strategy and target-state direction, working with Enterprise Architecture, Engineering, and programmes to establish a clear vision for how systems connect, share data, and enable business capabilities.
• Lead or support the evaluation of integration platforms and tooling (API management, event streaming, iPaaS, middleware), providing clear recommendations, reference architectures, and evidence to inform investment decisions.
• Assess the current integration estate with technical rigour, identify the highest-priority areas of fragility, duplication, and risk, and develop a phased modernisation roadmap with clear outcomes at each stage.
• Define and maintain the integration methodology - the patterns, standards, and decision frameworks that teams can use to design and deliver integrations consistently and well.
• Stay ahead of the curve on emerging integration technologies and approaches, ensuring the organisation's strategy reflects industry direction and does not accumulate avoidable technical debt.

Technical Architecture and Hands-On Design

• Produce detailed, technically credible integration architectures across all integration domains - SAP and ERP connectivity, e-commerce and digital channels, mobile platforms, data pipeline and analytics integrations, and third-party SaaS and partner systems.
• Lead technical spikes and proof-of-concept work to validate architectural approaches, evaluate tooling options, and de-risk delivery - getting hands-on where the situation demands it.
• Define and curate the integration patterns library, covering REST and GraphQL APIs, event-driven and pub/sub patterns, webhooks, message queuing and streaming (e.g. Apache Kafka, Amazon SQS/SNS, Amazon EventBridge), batch and near-real-time data exchange, and EDI.
• Architect API gateway strategy - including lifecycle management, versioning, consumer experience, and throttling - ensuring APIs are treated as products, not just interfaces (e.g. Amazon API Gateway, Kong, or equivalent).
• Ensure all integration designs address non-functional requirements: resilience, observability, scalability, fault tolerance, and operational manageability.
• Define patterns for real-time and near-real-time data flows, event-to-data pipelines, and data replication - ensuring integration and data architecture are coherent and complementary rather than misaligned.

Security, Key Management and Compliance

• Embed security as a first principle in all integration design - covering authentication and authorisation (OAuth 2.0, OIDC, mutual TLS), transport encryption, and consumer access control.
• Define and govern standards for secrets management, API key lifecycle, certificate rotation, and integration endpoint security (e.g. AWS Secrets Manager, AWS KMS), working in close partnership with Information Security.
• Identify and actively mitigate integration-level security risks including data leakage, misconfigured access, and injection vulnerabilities across the integration estate.

Standards, Governance and Delivery Enablement

• Provide integration architecture oversight through governance and assurance, helping ensure integration designs (in-house and vendor-delivered) align to agreed standards, patterns, and non-functional expectations.
• Act as a recognised integration domain expert in architecture forums, design reviews, and programme assurance - providing clear, technically grounded guidance, options, and recommendations.
• Work closely with the Enterprise Architect, Solution Architects, and engineering and delivery teams to ensure integration strategy is understood, applied, and continuously improved through delivery feedback.
• Build integration capability across the wider engineering community through documentation, design review participation, and direct technical engagement.

Key Challenges

• An integration estate built up over many years through largely project-driven, point-to-point decisions - requiring both strategic clarity and the technical credibility to drive meaningful consolidation and modernisation.
• A complex, multi-domain landscape spanning SAP, e-commerce, data platforms, mobile, and logistics - each with distinct integration needs, existing tooling, and delivery teams.
• High reliance on outsourced delivery, requiring the Integration Architect to set standards that vendors can follow consistently - and to govern outcomes without owning implementation directly.
• Significant commercial and operational dependency on integration reliability, making the balance between modernisation ambition and delivery stability a constant consideration.
• Establishing integration as a strategic, cross-cutting discipline in an organisation where architectural decisions have historically been made at a project or product level.

Success Measures

• A well-defined, widely understood integration strategy that is actively shaping technology investment decisions and delivery outcomes.
• Technology platform choices made with clarity and confidence, backed by evidence, and delivering measurable improvement in integration quality and maintainability.
• Measurable reduction in integration fragmentation, incidents, and rework as patterns are adopted and the legacy estate is modernised.
• Strong, productive working relationships with Data Platform, Reporting, Commerce, and SAP teams - with integration architecture recognised as an enabler rather than a constraint.
• Faster, more consistent integration delivery as reusable patterns, accelerators, and tooling take effect across delivery squads.
• Recognised as a trusted integration domain expert across Digital & Technology - by peers in the architecture community, by engineering and delivery teams, and by senior technology stakeholders.

What we're looking for

• Significant experience in integration architecture or senior integration engineering, with a demonstrable track record of shaping integration strategy, standards, and platform direction through delivery - not just documenting them.
• Deep, hands-on technical expertise across the integration technology spectrum: REST and GraphQL APIs, event-driven messaging and streaming (e.g. Apache Kafka, Amazon SQS/SNS, Amazon EventBridge), API gateways (e.g. Amazon API Gateway, Kong), and iPaaS platforms (e.g. MuleSoft, Boomi, AWS Step Functions, or equivalent).
• Strong AWS integration experience - including native AWS integration services and how they fit within a broader open-stack integration architecture.
• Proven experience with SAP integration - including SAP Integration Suite (formerly CPI), IDocs, BAPIs, and the challenges of connecting SAP to modern digital and data platforms.
• Strong background in data pipeline integration - including CDC, event-to-data flows, real-time feeds, and the interface between integration architecture and data platform design.
• Experience making and owning technology selection decisions - able to evaluate platforms critically, build a business case, and see choices through to implementation.
• Strong integration security knowledge: OAuth 2.0, OIDC, mutual TLS, secrets management, and AWS-native key and secrets tooling (AWS Secrets Manager, AWS KMS).
• Experienced operating at a senior level in complex organisations - credible with engineering teams and senior business and technology stakeholders alike, and able to lead without direct authority.
• Background in organisations with outsourced or heavily vendor-dependent delivery models, with the ability to set standards and govern quality without owning implementation directly.
