Job Summary:

The Engineering Lead is responsible for hands-on engineering delivery of enterprise AI/ML/GenAI and automation solutions, coding standards, design patterns, ensuring production-grade security, scalability, reliability, and supportability.  It is not a solution advisory, PoC, or platform administration role. Success is measured by the quality, reliability, scalability, and operability of AI systems in production.

Operating as a player–coach, the Engineering Lead works alongside AI Engineers to design and build ML Models, LLM pipelines and agentic workflows, while also setting engineering standards, coaching teams, and ensuring delivery.

The ideal candidate will possess:

• Extensive, hands-on software engineering experience, with a proven track record of building and operating complex systems in production environments.
• Strong executive communication and stakeholder management skills, with the ability to translate complex technical concepts into clear, business-relevant outcomes.
• Ability to independently design and code across multiple technical components, while guiding and elevating the work of senior engineers.
• Deep technical expertise across the full stack, including cloud-native architectures, distributed systems, and data-intensive platforms.
• Strong command of non-functional requirements, including reliability, availability, scalability, performance, and cost optimization, and the ability to make sound technology and architecture decisions as systems evolve over time.
• Demonstrated experience delivering production-grade Generative AI and Agentic AI solutions, including:
• LLM-powered applications and services
• Agentic workflows and orchestration frameworks
• Model integration, evaluation, and lifecycle management
• MLOps / LLMOps pipelines and operational practices
• Proven experience partnering with Data Science and AI Research teams to operationalize models and AI capabilities at enterprise scale.
• Ability to drive the design and delivery of AI-first architectures, including LLM-powered services, agentic workflows, orchestration layers, and human-in-the-loop systems.
• Experience building robust data and software foundations that enable advanced analytics, real-time AI inference, and intelligent decisioning at scale.

  • Build and evolve AI platforms that support:
    • Model lifecycle management
    • LLMOps / MLOps pipelines
    • Evaluation, monitoring, and drift detection
    • Secure access, auditability, and governance
  • Ensure AI systems meet enterprise non-functional requirements over time, not just at launch.

• Team Leadership & Capability Building
  • Lead and grow a team of senior engineers within the AI & Automation build function.
  • Coach engineers on:
    • Backend and distributed systems engineering
    • GenAI application design and implementation
    • Writing maintainable, testable, production-quality code
