Lead Forward-Deployed Engineer (Application Integration)

Description
We're looking for a Lead Forward-Deployed Engineer (Application Integration) to join our team in Lausanne, Switzerland in a hybrid working mode.Application integration for our client is at a turning point. MuleSoft has been the foundation for years, and now we’re shaping the next-generation landscape-continuing to use MuleSoft where it adds value and adopting AWS-native services where they are more scalable and cost-efficient.
You’ll join an international delivery team, working closely with the client’s solution architects, integration stakeholders and our lead in a collaborative, early-decision environment where your voice matters. As a Lead Forward-Deployed Engineer (Application Integration), you will sit at the intersection of engineering, architecture and business: assessing the current MuleSoft landscape, defining the target approach with architects, validating it through fast prototypes and helping scale proven patterns across the wider integration portfolio as a trusted technical partner.
Responsibilities
• Dive into existing MuleSoft APIs, flows and DataWeave transformations and work out what each one really needs to do
• Shape the future integration landscape with architects and stakeholders, and define clear criteria for what stays on MuleSoft and what moves to the cloud-native stack
• Choose the right AWS service per use case (AWS Glue, AWS Lambda, containers on EKS/Kubernetes, API Gateway, messaging and eventing services)
• Translate transformation logic into clean, maintainable AWS-native implementations where it makes sense
• Build prototypes quickly, using AI-assisted and agentic development tools and iterate in short feedback loops with the client
• Apply and promote best practices for integration architecture: security, observability, resilience, infrastructure as code and cost awareness
• Make clear, well-argued calls on feasibility, architecture and cost efficiency and explain the trade-offs in plain language
• Turn validated solutions into reusable patterns and hand them over to the delivery team
• Be the senior escalation point and "first responder" for integration questions on the client side
Requirements
• 6+ years of experience, including 3+ years in integration engineering and 2+ years in forward-deployed or solutions-engineering roles
• Hands-on MuleSoft experience (flows, APIs, DataWeave)
• Strong AWS experience: Lambda, Glue, API Gateway and event/messaging services
• Experience with Docker and Kubernetes (EKS)
• Solid understanding of API and integration architecture
• Confident, client-facing communication and the ability to work with architects and business stakeholders as an equal
• English proficiency at CEFR B2 level
Nice to Have
• Experience with AI-assisted/agentic development tools, Anthropic Claude or AWS Bedrock, Step Functions/EventBridge, Terraform/IaC
