Lead Forward-Deployed Engineer (Application Integration)

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 Switzerland 5 weeks of vacation EPAM Employee Stock Purchase Plan (ESPP) Enhanced parental leave Extended pension plan Daily sickness allowance insurance Employee assistance program Global business travel medical and accident insurance Learning and development opportunities including in-house training and coaching, professional certifications, and courses *All benefits and perks are subject to certain eligibility requirements
