One Redwood\nMake Your Own Weather\nObsess over Customer Success\nWork the Problem\nBe Curious\nOwn the Outcome\nRespect Each Other\n YOUR IMPACT\nAs 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.\nDesign, develop, test, and maintain native software supporting connectivity and integration with IBM i (AS/400) environments.\nBuild native job submission and monitoring, spool file and message/data queue handling, and CL/RPG program invocation capabilities.\nIntegrate 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).\nIntegrate security and per-user authorization using IBM i user profiles and authority concepts while extending Redwood’s existing identity and credential management capabilities.\nTroubleshoot complex system-level issues across IBM i, Unix, and Java environments.\nImprove the reliability, performance, security, and scalability of Redwood’s IBM i solutions.\nPartner with product managers, architects, and engineers to translate customer requirements into effective technical solutions.\nParticipate in architecture discussions, design reviews, code reviews, testing, and release planning.\nLeverage agentic AI to accelerate implementation, testing, and documentation while independently verifying correctness against authoritative IBM i references.\nDocument connector behavior and platform prerequisites for field and support teams.\nContribute 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.\nYOUR EXPERIENCE\n10+ years of professional software engineering experience with strong Java 8+ skills.\nHands-on IBM i (AS/400) integration experience, including CL, native job/spool/queue APIs, IBM Toolbox for Java (JTOpen/jt400), and DB2 for i.\nWorking proficiency in C, including ILE C on IBM i.\nExperience integrating with vendor host-server or RPC-style APIs over TCP/IP, including connection lifecycle management and error handling.\nStrong concurrency and multithreading skills, with experience building resilient, long-running monitoring components such as job polling and spool/file event detection.\nAbility to work effectively from primary technical sources, including IBM i host-server and API references, rather than relying solely on tutorials or unverified AI-generated output.\nExperience with modern DevOps practices and technologies, including Git, CI/CD, Docker, and Kubernetes.\nFluency with AI tools in a production engineering environment.\nStrong code judgment, including the ability to identify plausible but incorrect AI-generated recommendations involving specialized IBM i APIs.\nProficiency in prompting AI tools, combined with the judgment to recognize when a task is too specialized for AI-assisted approaches.\nAbility to maintain an architectural focus, abstracting from individual API and connector details to shared platform-integration designs.\nExperience with workload automation products such as Tidal, CA-7, Control-M, Stonebranch, BMC, or RunMyJobs preferred.\nExperience with IBM i clustering or high-availability configurations preferred.\nFamiliarity with advanced IBM i security concepts, including authorization lists and adopted authority, preferred.\nBackground working with RPG/COBOL environments or IBM i modernization projects preferred.\nMainframe or midrange migration project experience preferred.\nIf you like growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us!\nTHE LEGAL BIT\nRedwood is an equal opportunity employer.
