• Create reusable components for prompt management, evaluators, safety filters, connectors, embeddings pipelines, and memory stores 
• Build and operate LLM-powered APIs and microservices integrated into advisor, client, and internal workflows 
• Own the end-to-end ML lifecycle: experimentation, CI/CD, automated testing, monitoring, drift detection, versioning, and rollback 
• Optimize inference for latency, throughput, caching, batching, model selection, and cost per inference 
• Partner with data teams on structured and unstructured data pipelines, document ingestion, metadata, and access controls 
• Set engineering standards for agentic AI systems and lead design reviews 
• Influence roadmap and priorities through technical insight and delivery 
• Architects and governs agentic AI-enabled engineering workflows (using enterprise-authorized tools within the work environment) to improve delivery speed, code quality, and operational outcomes at scale (e.g., AI-driven PR review assistance, test generation/maintenance, release readiness checks, incident triage and root-cause acceleration), while defining guardrails for validation, security, resiliency, and reuse across teams.
• Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation at scale. 

Required Qualifications, Capabilities, and Skills: 

• Formal training or certification on software engineering concepts and 7+ years applied experience 
• Strong Python engineering skills; experience with PyTorch or TensorFlow 
• Expertise working with Vector storage systems and designing memory for Agents 
• Expertise developing long running agents that run autonomously using tools, skills and human in the loop 
• Proven experience deploying LLM-backed services to production (APIs, microservices)

• Cloud-native AI deployment experience (AWS or Azure), with cost and performance optimization 
• Demonstrated commitment to responsible AI practices and operational excellence 
• Strong communication and collaboration skills, working across product, risk, legal, and compliance teams 
• Demonstrated experience designing and leading adoption of agentic AI-enabled development practices (using enterprise-authorized tools within the work environment) across teams, including setting standards for human-in-the-loop validation, auditability/traceability of changes, and secure handling of sensitive data. 
• Strong understanding of responsible AI use and control expectations in engineering workflows, including security/resiliency implications, data sensitivity, and risk-based governance; ability to influence senior technical leaders on safe scaling patterns and reuse.  

Preferred Qualifications, Capabilities, and Skills: 

• Experience with fine-tuning, adapters, or custom evaluation frameworks 
• Background operating AI systems in regulated environments (finance, healthcare, etc.) 
• Experience with prompt engineering and LLM orchestration
