About The Position

UniGroup is seeking a hands-on Engineering Manager to lead a key modernization initiative. This role is ideal for someone who can actively contribute to technical design and implementation while managing a small-to-mid-sized team. The team is focused on transforming legacy mainframe workloads into modern, cloud-native systems, leveraging tools such as AWS Transform and Rocket Software. This is a fully remote position, but candidates must live in Missouri, Illinois, Arkansas, Georgia, Tennessee, North Carolina, Texas, Florida, or Indiana. Preference will be given to local candidates, particularly those residing in Missouri.

Requirements

• Strong hands-on experience with AWS (designing, building, and operating systems)
• Proficiency in Java (or similar modern language), Spring Boot, Node, React, PostgreSQL, Kafka, TypeScript, GraphQL, Git, CI/CD, AWS, Docker, and Kubernetes
• Recent coding experience
• Experience building distributed systems, APIs, and microservices
• Comfortable getting into the codebase when needed — this is not a purely managerial role
• Experience managing engineers while remaining technically credible and involved
• Leads by example — willing to roll up sleeves and unblock the team directly
• Strong problem-solving mindset in ambiguous, evolving environments
• Able to balance execution speed with long-term architecture quality
• Candidates must be legally authorized to work in the United States on a permanent basis
• UniGroup is unable to provide visa sponsorship or employment authorization support now or in the future

Nice To Haves

• Exposure to mainframe technologies (COBOL, JCL, DB2, CICS) or legacy systems
• Experience with modernization/migration tools (e.g., AWS Transform, Rocket Software)
• Background in large-scale system refactoring or re-architecture

Responsibilities

• Lead and actively contribute to the modernization of mainframe applications
• Drive architecture, design decisions, and implementation for migrating legacy systems to AWS
• Work closely with engineers on code reviews, design reviews, and debugging complex issues
• Break down monolithic systems into microservices / modular architectures
• Evaluate and integrate tooling for automated transformation and migration
• Partner with product and platform teams to align on roadmap and execution

Benefits

• Competitive compensation and a comprehensive benefits package
• Medical, dental, and vision insurance with multiple plan options
• 401(k) retirement plan with company match
• Paid time off, company holidays, and paid parental leave
• Hybrid work environment that supports flexibility and work-life balance
