JOB DESCRIPTION We are seeking a hands-on Systems Engineer (SME) with deep expertise across infrastructure, platforms, and application ecosystems spanning cloud and on-premises environments. This role requires a proven practitioner who can analyze existing (as-is) systems and applications, document current state architectures, design future-state solutions, and implement system enhancements or technology transformations end-to- end. The ideal candidate is a technical leader and doer, not just an advisor - someone who can seamlessly collaborate across infrastructure, platform, application, DevSecOps, information systems security, and data teams while maintaining ownership of system reliability, performance, scalability, and security. Recognized SME with deep, hands-on technical expertise. Strong systems thinker with the ability to see and engineer across the full stack. Comfortable operating at both strategic architecture and tactical implementation levels. Excellent communication and collaboration skills across technical and non-technical teams.
