Job description

We’re Pret: proud makers of freshly made food, organic coffee, and big ideas. Across 750+ shops and 20+ countries, our teams are shaping the future of Pret through innovation, inclusion, great customer service and a shared passion for doing the right thing. We’re growing fast on our mission to be the employer of choice in hospitality, everywhere we operate – so this an exciting time to hop on board.

We Believe in Growing Good Things

Growth is at the heart of everything we do. From the freshly hand-made food we create every day, to supporting our teams, we help our people grow in confidence, skills and to pursue their unique paths. Pret is where passionate, hardworking, wonderful people (like you!) find what they need to shine. And the proof is in the pudding – over 80% of our Managers started on the shop floor! So did 20% of our Support Centre teams, including our CEO, Pano.

What we’re looking for

We’re looking for passionate team players to bring joy to our customers every day. As a Lead Integrations Engineer, you’ll set the standards and patterns the Integrations Engineers follow across our Azure integration stack (APIM, Logic Apps, Function Apps, Service Bus, Event Grid), line‑manage the team, and personally deliver the most complex and highest‑risk flows in the estate. All new integration assets at Pret are being built on Azure; the legacy MuleSoft Anypoint estate is in a controlled wind‑down through this programme. You will own that migration end to end and keep the legacy MuleSoft flows safely operational and well‑led until they retire. Expect to spend roughly half your week in code, building, debugging, reviewing pull requests, pairing with engineers and the other half on architecture, standards, vendor conversations, team leadership and stakeholder engagement.

This is the key technical leadership role for integrations at Pret. Reporting to the Head of Data & Integrations, you will lead Pret’s Integrations team and own the target architecture that connects our SaaS platforms, including Workday, Oracle Symphony, NetSuite and e‑commerce systems, with our data, finance and operational platforms.

You will also be responsible for building the team’s most complex integrations yourself, using the same tools and technologies as the rest of the team. We are not looking for a hands‑off manager.

This role is for a senior engineer who has grown into leadership without losing their technical edge. You will have led an integrations team working across both MuleSoft and Azure and understand first‑hand what it takes to migrate an integration estate from one platform to the other without disrupting the business.

If your last hands‑on Azure integration build was three years ago, this is probably not the role for you. But if you still enjoy tackling a challenging Function App on a Friday afternoon while also developing and mentoring a high‑performing team, we’d love to hear from you.

Key Responsibilities

• Act as the technical owner for the integration’s estate: the single accountable engineering voice on integration architecture, standards and delivery, reporting to the Head of Data & Integrations.
• Line-manage the Integrations Engineers (FTE and FTC): own performance, development, one-to-ones, and the team's engineering culture.
• Own the integration architecture for Pret's SaaS source systems and internal services, including Workday, Oracle Symphony, NetSuite, ecommerce platforms and others. All new build is on Azure.
• Personally design and build the hardest, highest-risk integrations on the Azure integration stack (APIM, Logic Apps, Function Apps, Service Bus, Event Grid).
• Lead the team through the controlled wind-down of the legacy MuleSoft Anypoint estate: keep it safely operational while in use, sequence and migrate flows onto the Azure stack on the programme timeline and decommission cleanly.
• Define and enforce integration patterns and standards across the team: API design, event-driven flows, retry / error handling, idempotency, observability, security all anchored on Azure-native services.
• Produce reference implementations on the Azure stack that the team builds from APIM API templates, Function App patterns, Service Bus topologies, deployment pipelines.
• Run a healthy engineering practice in the team: review every non-trivial pull request, pair on the hardest pieces, unblock the team in code where needed, and grow more junior engineers.
• Build and maintain the team's engineering toolchain on Azure DevOps / GitHub Actions CI/CD pipelines, test frameworks, observability dashboards in Application Insights and Log Analytics.
• Work with the Data Engineering on the boundary between integration and data engineering, which data lands where, in what shape, on what cadence.
• Define and maintain the API and integration catalogue: what we have, who owns it, what it does, what SLA it runs to.
• Manage supplier and vendor relationships across the integration stack, including Microsoft, the MuleSoft wind-down, and any third‑party connectors.
• Be the senior technical voice in vendor and SaaS conversations on integration capability.
• Act as senior technical escalation point and on-call backstop for major integration incidents, including evenings and weekends where required. Expect to be the one in the flow on Sunday night when a Workday-to-NetSuite job has fallen over.
• Report progress, risks and architectural decisions clearly to the Head of Data & Integrations and to programme leadership.
• Stay current with developments in Azure integration services and bring practical, working recommendations back to the team ideally as proof‑of‑concept code.
