Job description

1. Integration Strategy & Domain Architecture (Freedom & Quality)

• Define, design, and govern enterprise-grade integration architectures across our hybrid-cloud ecosystem, ensuring high availability, fault tolerance, and low latency.
• Act as a Segment Domain Expert: Deeply understand the business processes, data flows, and operational nuances of our core business segments (e.g., Petcare, Snacking, Food) to design integrations that solve real business problems.
• Architect end-to-end integration flows connecting core enterprise systems, including ERPs (SAP S/4HANA), CRMs (Salesforce), Warehouse Management Systems (WMS), and Retail POS systems.
• Champion API-Led Connectivity and Event-Driven Architecture (EDA) as the foundational paradigms for global business operations.
• Establish reusable integration patterns, templates, and frameworks that accelerate time-to-market for digital initiatives across different business units.

2. Technology Leadership & Platform Governance (Efficiency & Quality)

Provide deep architectural expertise and hands-on design leadership across our core integration platforms:

• SAP BTP Integration Suite (SAP BTP IS): Lead core ERP and cloud line-of-business integrations (e.g., Cloud Integration, API Management)
• Azure Integration Services (Azure IS): Drive cloud-native workflows, event routing, and messaging using Logic Apps, Service Bus, Event Grid, and Azure API Management
• MuleSoft Anypoint Platform: Govern API portfolios, design reusable RAML/OAS specs, and establish robust runtime engine deployments (CloudHub/hybrid)
• Solace PubSub+: Design and implement real-time, high-performance event brokers and streaming frameworks for globally distributed supply chain and manufacturing operations.
• OpenText: Architect secure, high-volume B2B integration networks and EDI systems to support transactional exchanges with global retailers and logistics partners.
• Collaborate with DevOps and Platform squads to implement modern, automated CI/CD pipelines, containersation, and infrastructure-as-code for integration deployments.

3. Stakeholder Collaboration & Mutuality (Mutuality)

• Act as a trusted consultant to Business Partners, Functional Leads, and external partners, translating complex business processes into elegant technical designs.
• Partner closely with security, data privacy, and compliance teams to enforce robust authentication standards (OAuth, OIDC, SAML), encryption at rest/transit, and compliance with global regulations (GDPR, CCPA).
• Present clear, value-driven architectural proposals to digital leadership, demonstrating how technology choices support business enablement.
• Drive a culture of Domain Excellence within the technical team, encouraging developers and junior architects to build deep expertise in specific business segments and processes rather than remaining pure technical generalists.
• Keep a pulse on emerging industry trends, cloud paradigms, iPaaS innovations, and modern B2B integration capabilities, steering the technology roadmap accordingly.
• Establish a culture of shared learning; mentor junior integration architects and developers, conducting design reviews to elevate collective technical capability.

Required Experience & Qualifications

• CPG/FMCG Sector Experience: Minimum of 5+ years of experience working within a global Consumer Packaged Goods, retail, or manufacturing enterprise (or serving such clients in an architectural consulting capacity).
• Segment Domain Mindset: Proven ability or strong desire to move beyond purely technical execution to become a true domain expert in core CPG business processes, specifically:
• Order-to-Cash (O2C): Customer orders, pricing, billing, and retail POS integrations.
• Procure-to-Pay (P2P): Supplier interactions and procurement flows.
• Supply Chain & Logistics: Logistics execution, 3PL/4PL integrations, Warehouse Management Systems (WMS), inventory visibility, and product serialisation (GS1 standards).

Technical Stack & Platform Expertise

• MuleSoft Anypoint Platform: Solid experience designing and governing API-led connectivity, managing API policies, and configuring CloudHub.
• Azure Integration Services: Proven expertise with Logic Apps, Service Bus, Event Grid, and Azure APIM.
• SAP BTP Integration Suite: Deep hands-on experience integrating SAP environments (S/4HANA, ECC) with external cloud platforms and cloud LOBs (Ariba, SuccessFactors).
• Solace PubSub+: Experience implementing event mesh networks, real-time message routing, and publish/subscribe patterns.
• OpenText: Proven track record in B2B/EDI integration, automated document processing, and managed integration services (EDIFACT, ANSI X12, AS2, SFTP standards).
• Modern Protocols & Formats: Expertise in REST, SOAP, gRPC, JSON, XML, and flat-file integration patterns.
• Principle-Driven Leadership: Ability to operate under a values-based framework, demonstrating strong personal accountability and mutual respect.
• Collaborative Mindset: Strong active listening, communication, and negotiation skills, with an innate ability to build bridges across global, multicultural teams.
• Problem-Solving & Agility: Strong analytical capability, comfortable navigating ambiguity in a fast-paced, digital environment.

Education & Certifications

• Bachelor’s or Master’s degree in Computer Science, Information Technology, Engineering, or a highly related field.
• Professional certifications in relevant technologies (e.g., MuleSoft Certified Integration Architect, Azure Solutions Architect, SAP Certified Integration Associate, or Solace Certified Engineer) are highly desirable.
