• Collaborate with business partners, Product Owners, and the Contact Center Transformation Lead to translate business requirements and customer journey designs into technically sound agent implementations
• Apply and evaluate large language models within agent workflows including prompt design, retrieval, and output evaluation to improve accuracy, safety, and reliability
• Support the tuning and optimization of digital agents post‑launch by analyzing conversation logs, identifying failure points, and implementing improvements in partnership with the AI Optimization team
• Maintain technical documentation including SDDs, integration specifications, and configuration records to ensure continuity and supportability across the team

• Proficiency integrating AI platforms with enterprise systems via REST APIs, MuleSoft, or similar middleware and integration frameworks
• Familiarity with CRM platforms (Salesforce preferred) and ERP systems (SAP preferred) in the context of agent‑driven transaction execution
• Experience with CCaaS platforms such as Five9 or Genesys, including understanding of call routing, SIP/PSTN flows, and agent handoff patterns
• Solid understanding of NLU/NLP concepts including intent classification, entity extraction, dialogue management, and confidence thresholds
• Experience performing system integration testing and documenting test cases, results, and defect tracking
• Strong written and verbal communication skills with the ability to collaborate across technical and non‑technical stakeholders
