Responsibilities

• 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.

• 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.

• 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.
