• Partner closely with data scientists, ML engineers, and product engineers to productionize statistical and AI/ML capabilities into reliable, real-time backend infrastructure.
• Lead complex, multi-team, multi-quarter technical initiatives end-to-end: from problem framing and technical strategy through implementation, launch, and long-term operational ownership.
• Influence the engineering roadmap and technical strategy across the Convert pillar and partner pillars, identifying the highest-leverage investments and aligning teams behind them.
• Raise the engineering bar across the org through architecture review, technical standards, observability and operational excellence practices, and the systems and tooling that support long-term quality.
• Mentor and grow staff and senior engineers, multiplying your impact through the people you develop and the technical culture you help shape.
• Stay current with industry trends in distributed systems, experimentation platforms, real-time data, and AI/ML infrastructure, and proactively identify opportunities to advance Webflow's backend platform and engineering practices.
• Translate product vision into concrete technical problems and execution plans.
