Software Engineer – Principal, IBM i (AS/400) Connectivity

As a Software Engineer – Principal, IBM i (AS/400) Connectivity, you will help build a new connectivity agent that extends Redwood RunMyJobs (RMJ) natively onto IBM i (AS/400), enabling Redwood to support some of the largest enterprise automation environments in the market. You will join a small, senior team building this capability largely from first principles, validating assumptions on live IBM i partitions and making architectural decisions where modern documentation may be limited.

This position is open across levels from Software Engineer to Principal as we build out the team.

• Design, develop, test, and maintain native software supporting connectivity and integration with IBM i (AS/400) environments.
• Build native job submission and monitoring, spool file and message/data queue handling, and CL/RPG program invocation capabilities.
• Integrate IBM i functionality with the Redwood platform through clean, versioned extension points using native host server APIs and/or IBM Toolbox for Java (JTOpen/jt400).
• Integrate security and per-user authorization using IBM i user profiles and authority concepts while extending Redwood’s existing identity and credential management capabilities.
• Troubleshoot complex system-level issues across IBM i, Unix, and Java environments.
• Improve the reliability, performance, security, and scalability of Redwood’s IBM i solutions.
• Partner with product managers, architects, and engineers to translate customer requirements into effective technical solutions.
• Participate in architecture discussions, design reviews, code reviews, testing, and release planning.
• Leverage agentic AI to accelerate implementation, testing, and documentation while independently verifying correctness against authoritative IBM i references.
• Document connector behavior and platform prerequisites for field and support teams.
• Contribute to team success through clear communication, shared responsibility for quality, and accountable ownership of goals and delivery commitments in a fast-paced, iterative agile environment.
