Configure test environments daily using the eManager Portal to set up test cards, prompts, and velocity limits for assigned regional accounts.

Collaborate weekly with client engineering teams to establish secure network connectivity (SSL, VPN, Direct Connect) while proactively adopting AI-assisted diagnostic tools and process automation scripts to optimize manual testing workflows.

Technical Specification Adherence & Operations Support:

Serve as a primary technical resource expert for assigned regions, ensuring strict adherence to technical interface specifications, including ISO 8583 Card Payment Authorization and Proprietary Sales Transaction files.

Resolve production authorization anomalies, POS terminal equipment issues, and transaction data file questions during outage reconciliations weekly.

Proactively identify and embrace opportunities to integrate AI and automation technologies into operational processes. This includes initiatives to drive scale, reduce reliance on manual processes, and mitigate operational risks.

Stakeholder Communication & Project Management:

Lead weekly kickoff meetings, technical alignment sessions, and project updates as the primary technical point of contact with external merchants and internal teams (Merchant Development, NetOps, Product Support).
