Job Description & Details
This is a heavy-hitting architecture gig focused squarely on modernizing legacy B2B integration pipelines for a massive financial institution. If you know your way around IBM Sterling infrastructure and aren't afraid to untangle enterprise network topologies, this year-long contract will keep you deeply challenged.
What You'll Actually Be Doing
Your primary mission is to steer the modernization and upgrade path for IBM Sterling Integrator from version 5.x to 6.x, while tightening up secure file transfer protocols in the DMZ. You'll spend your days collaborating directly with security and network engineers to design bulletproof disaster recovery setups, map out external client connectivity, and iron out bottlenecks in high-volume data exchanges. Expect to balance high-level systems design with deep-dive troubleshooting when complex B2B pipelines hit a snag.
The Core Tech Stack
You need absolute mastery over IBM Sterling Integrator (SI) 5.2.6+ and Sterling Secure Proxy (SSP), coupled with rock-solid fluency in BPML, XML, XPath, and XSLT. Beyond the core file transfer tooling, success here demands a firm grip on network architecture—think Load Balancers, Firewalls, Reverse Proxies, and strict SSL/TLS configurations. If you also bring along exposure to containerization, OpenShift, or modern CI/CD tools like Jenkins and Ansible, you'll easily stand out from the pack.
Interview Expectations
The hiring manager is going to probe heavily into your hands-on experience handling complex version upgrades and migrating critical integrations without causing downtime. Be prepared to walk through a specific scenario where you troubleshot a high-availability B2B failure involving DMZ boundary crossings or complex authentication chains, as they want to see how you troubleshoot under pressure.
Application Advice
Make sure your resume doesn't just list tool names, but explicitly highlights your end-to-end architecture work with IBM Sterling SI and SSP. Mirror the exact terminology from the job description—such as 'BPML,' 'Sterling Secure Proxy,' and 'external authenticator'—to ensure you easily clear the initial automated keyword filters.
