Senior Full-Stack Engineer

Why we're hiring:

WPP Enterprise Technology delivers IT services across the WPP group — enabling the world's most creative brands to co 

We are looking for a seasoned full-stack engineer who enjoys systems design, integration complexity, and intelligent workflow automation. You will join our Global Automation & Business Platforms programme and take ownership of designing, building, and refining production-grade solutions — both as standalone products and as integrations within our core Hero portfolio. 

Day-to-day you will architect event-driven pipelines, build Python and React services, wire together enterprise APIs, and make smart engineering decisions on frameworks and data models.  

 

What you'll be doing:

Solution Design & Delivery 

• Design and develop full-stack solutions (Python back-end, React front-end) that integrate with portfolio products or run as standalone platforms. 
• Architect service-to-service integration patterns: synchronous APIs, event queues, webhook pipelines, and scheduled batch processes. 
• Build and maintain FastAPI services with clear contracts, versioning, and observability from day one. 

Workflow & Automation Engineering 

• Implement sophisticated multi-step automation workflows that coordinate actions across enterprise systems — document management, CRM, HR, finance, and media platforms. 
• Build integrations between internal data sources, third-party APIs, and cloud platform services (Azure, GCP). 

Quality, Governance & Documentation 

• Build evaluation and testing frameworks so that every automated workflow is measurable, auditable, and improvable. 
• Work closely with the Engineering Lead to define governance standards: access control, audit logging, safe defaults, and compliance guardrails. 
• Maintain thorough technical documentation — architecture diagrams, runbooks, API specs, and decision records. 

Collaboration 

• Operate within an Agile Kanban team, taking stories from backlog refinement through to production deployment. 
• Act as the technical bridge between business stakeholders and engineering: translating requirements into pragmatic designs and communicating trade-offs clearly.
• Support other automation delivery teams across WPP with technical guidance and code reviews. 

 

What you'll need:

Essential 

• 7–9 years of professional software engineering experience, with Python as the primary back-end language. 
• Strong React / TypeScript front-end skills — you can build and own the full vertical, not just the API layer. 
• Solid FastAPI or equivalent Python API framework experience; you know how to structure a production service. 
• Proven experience designing and operating event-driven or pipeline architectures (queues, schedulers, webhooks, streaming). 
• Comfortable working across cloud platforms — Azure and/or GCP — including managed services for compute, storage, and messaging. 
• Experience integrating with enterprise identity, directory, and SaaS APIs (Microsoft 365 ecosystem is a strong advantage). 
• Hands-on experience building search or retrieval-augmented systems: embedding pipelines, vector databases, semantic indexing. 
• Solid understanding of evaluation and testing practices for complex, non-deterministic systems. 
• Agile practitioner — comfortable in Kanban or Scrum, familiar with backlog management, sprint ceremonies, and incremental delivery. 
• Excellent written and verbal English; you document your work and communicate clearly with both engineers and non-technical stakeholders. 

Nice to Have 

• Familiarity with Microsoft Copilot Studio or Power Platform. 
• Exposure to enterprise-grade governance patterns: RBAC, audit trails, policy-as-code. 

Certifications 

Mandatory (required in first 30 days) 

• Microsoft Azure AI Engineer Associate (AI-102) 

Desirable / Required within 3 months 

• GitHub Copilot (GH-300) 
• Microsoft Power Platform Fundamentals (PL-900)
