• Establish observability, monitoring, and evaluation capabilities that enable measurable and repeatable quality outcomes.
• Review and approve key technical designs and architectural decisions.
• Promote engineering rigor through technical reviews, documentation, and standards adoption.
• Ensure technical quality, maintainability, and operational readiness across platform and agent capabilities.

Platform and Product Delivery

• Partner with product management and engineering leadership to translate business objectives into technical strategy and execution plans.
• Create reusable frameworks, patterns, and reference implementations that accelerate platform development and adoption.
• Drive continuous improvement of platform capabilities, reliability, operational efficiency, and developer experience.
• Balance technical innovation with business priorities, delivery timelines, and operational requirements.

Technical Mentorship and Influence

• Mentor and develop engineers through technical coaching, design reviews, and knowledge sharing.
• Foster adoption of engineering standards, best practices, and platform patterns across teams.
• Influence technical decision-making through expertise, collaboration, and leadership without direct authority.
• Build engineering capability by promoting high standards of technical excellence and craftsmanship.

Security, Governance, and Operations

• Ensure platform designs incorporate security, privacy, compliance, auditability, and responsible AI considerations.
• Partner with security, governance, and architecture stakeholders to meet enterprise requirements.
• Drive operational excellence through monitoring, resilience, capacity planning, cost optimization, and incident readiness.
• Champion secure‑by‑design and reliable‑by‑design engineering practices across the platform.

Required

• Extensive software engineering experience with a proven record of technical leadership across multiple teams and organizations.
• Deep experience designing, building, and operating distributed systems, cloud-native platforms, APIs, and event‑driven architectures.
• Hands‑on experience building and delivering LLM‑powered applications, AI systems, or agent‑based solutions in production environments.
