In this hands-on leadership role, you will serve as the technical lead across two high-impact organizations—the AI Platform group and the AI Solutions and Support group—defining architectural vision, establishing core enterprise infrastructure, such as model gateways and context management, and driving production-grade AI applications and operational workflows across global teams.
What you'll do
- Architect and scale enterprise AI platform capabilities, including model gateways, intelligent routing, cost governance, LLM observability, evaluation pipelines, and long-term agent memory
- Direct technical execution for AI solutions and support, spearheading enterprise AI platform administration, intelligent search experiences, and scalable L2 operational support frameworks
- Lead distributed engineering teams across the US and India, aligning roadmap priorities, conducting technical reviews, and fostering seamless communication across time zones
- Establish engineering excellence and production AI quality gates, overseeing hands-on code development, CI/CD pipelines, regression suites, and latency and cost optimization
- Partner with cross-functional stakeholders in Security, Legal, Privacy, and enterprise business units to ensure compliant, secure, and impactful AI enablement
Who You Are
- You are a seasoned technical leader who thrives at the intersection of enterprise architecture, distributed team leadership, and hands-on software engineering.
- You possess deep technical breadth in architecting production-grade LLM applications, retrieval-augmented generation systems, and comprehensive AI evaluation frameworks.
- You are an operational driver with a proven track record of reducing systemic friction, resolving production incidents, and automating support processes.
- You excel at bridging time zones and cultures, empowering both internal engineers and external partners through empathetic mentorship and clear technical guidance.
- You are an articulate communicator and collaborative partner who seamlessly aligns technical strategy with executive stakeholders across business, security, and governance functions.
What We're Looking for
- Demonstrated hands-on experience building and deploying production-grade AI/LLM applications, including prompt engineering, retrieval-augmented generation (RAG), agents, function calling/MCP, and model evaluation or observability frameworks
- 8+ years of professional software engineering experience, with a Bachelor's or Master's degree in Computer Science, Engineering, or equivalent practical experience
- 3+ years of technical leadership experience guiding distributed engineering teams and external contractors across multiple time zones
- Proficiency in full-stack development utilizing Python, TypeScript/Node.js (or Java/Go), modern front-end frameworks like React, and robust API design
- Hands-on expertise in cloud and containerized infrastructure, including AWS (or GCP/Azure), Docker, Kubernetes, and automated CI/CD deployment pipelines
- Proven background operating production enterprise services, including incident response, on-call management, runbook development, and SLA governance
What Will Make You Stand Out
- Advanced expertise administering enterprise AI platforms (such as OpenAI, Anthropic Claude, Amazon Bedrock, or Google Vertex AI) with comprehensive cost governance, security controls, and usage optimization
- Experience architecting vector and graph database solutions, semantic caching, and dynamic long-term agent memory management
- Proven success deploying intelligent conversational bots, search experiences, and Slack integrations within enterprise workflows, alongside familiarity with model fine-tuning, open-weight model serving, or compliance standards in regulated environments such as FedRAMP
