Job summary

EPAM Systems Inc. is seeking a Lead Forward-Deployed Engineer (Application Integration) in Lausanne, Switzerland, offering a hybrid work model. You will assess the MuleSoft landscape, define a target approach with architects, and prototype to validate-and-scale patterns across the portfolio.

You will lead engineering and architecture decisions, collaborate with client stakeholders, and drive cost-aware, secure integration solutions using MuleSoft and AWS services. Fluency in English is required.

Qualifications

• 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).

• Translate transformation logic into clean, maintainable AWS-native implementations where it makes sense.
• Build prototypes quickly using AI-assisted tools and iterate in short feedback loops with the client.
• Apply and promote best practices for integration architecture: security, observability, resilience, IaC and cost awareness.
