What we’re looking for  

We’re looking for a Software Engineer III who is passionate about building reliable, scalable backend systems and enjoys working across the stack when needed. You are a hands‑on engineer who thrives on solving real‑world problems, writing clean and maintainable code, and collaborating closely with teammates to deliver high‑quality features end‑to‑end. 

You bring strong engineering fundamentals, a growth mindset, and the ability to work independently on well‑scoped projects — owning medium‑sized features from design through deployment in alignment with our engineering best practices. You’re comfortable contributing to technical discussions, making thoughtful trade‑offs, and following established architectural patterns as you deepen your understanding of our systems. 

This role is fully remote, based in India and offers the opportunity to meaningfully influence backend architecture, shape engineering best practices, and work with a mission-driven, high-performing team.  

What you’ll own  

As a Software Engineer III, you will have clear ownership over features, with opportunities to contribute across the stack:  

• Own and deliver small to medium-sized backend features end-to-end: From technical discovery and design through implementation, testing, deployment and iteration 

• Take technical ownership of one or more non‑critical backend services or components: Ensuring they remain reliable, maintainable, well‑documented, and easy to extend. 

• Write clean, modular, testable code: Primarily in Ruby, Ruby on Rails, and Python, while contributing to frontend code when needed to support full‑stack feature delivery. 

• Contribute to the design and evolution of our APIs: Including GraphQL and REST endpoints that power frontend and partner‑facing applications, following established architectural patterns and best practices. 

• Ensure strong observability and operational health of owned services: Through logging, monitoring, alerting, and contributing to root‑cause analysis and follow‑through improvements. 

• Actively participate in technical discussions: Bringing thoughtful perspectives that balance simplicity, long‑term maintainability, and performance as you deepen your understanding of Perch’s systems. 

• Support team productivity through high‑quality code reviews and collaboration: Sharing context, helping unblock others, and contributing to a strong engineering culture. 

What you’ll do  

• Design and build scalable, resilient backend systems using Ruby on Rails, Python and PostgreSQL  

• Contribute to implementation of complex features and integrations, including external systems such as Salesforce  

• Take technical design decisions independently for your features

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)
