About The Position

We’re hiring 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.

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

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
