About The Position

At Webflow, we're building the world's leading AI-native Digital Experience Platform, and we're doing it as a remote-first company built on trust, transparency, and a whole lot of creativity. This work takes grit, because we move fast, without ever sacrificing craft or quality. Our mission is to bring development superpowers to everyone. From entrepreneurs launching their first idea to global enterprises scaling their digital presence, we empower teams to design, launch, and optimize for the web without barriers. We believe the future of the web, and work, is more open, more creative, and more equitable. And we're here to build it together.
We're looking for a Senior Staff Software Engineer to help lead the technical future of Convert — our suite of products that give marketing and growth teams the tools to experiment, personalize, and drive real revenue from their web presence.
The next chapter is ambitious: we're serving some of the world’s largest enterprises and rethinking what a modern, AI-native conversion platform can be. This is a cross-team technical leadership role, which means you’re working across a large, complex, revenue-generating system and figuring out what it needs to become. You'll partner directly with senior leaders across Engineering, Product, and Design to turn that vision into something you can actually ship.

Requirements

• BS / BA college degree or relevant experience
• 12+ years of software engineering experience, including extensive expertise architecting and operating backend systems and distributed systems at significant scale.
• A strong technical foundation across multiple programming languages such as Python, Java, or Go, with deep fluency in modern frameworks, distributed systems patterns, and large-scale system design.
• Designed, built, and operated high-throughput, data-intensive distributed systems in production — with deep understanding of scalability, fault tolerance, consistency tradeoffs, observability, and performance optimization.
• Demonstrated technical leadership across ambiguous, cross-pillar initiatives, influencing architecture, execution, and engineering strategy well beyond your immediate team.
• Partner effectively with product, design, data science, and ML stakeholders to translate evolving business needs and customer outcomes into scalable technical solutions.
• Strong judgment, communicate clearly with both technical and executive audiences, and make pragmatic tradeoffs in fast-moving environments.
• Demonstrate a proactive embrace of AI, and actively building and applying fluency in emerging technologies to elevate how we work, drive faster outcomes, and expand collective impact.
• Stay curious and open to growth — demonstrating a proactive embrace of AI, and actively building and applying fluency in emerging technologies to elevate how we work, drive faster outcomes, and expand collective impact.

Nice To Haves

• Experience with experimentation platforms (A/B testing, feature flagging, multi-armed bandits), personalization or recommendation systems, marketing analytics, or customer data platforms.
• Familiarity with the statistical foundations of online experimentation (variance reduction, sequential testing, CUPED, etc.) and the infrastructure required to support them at scale.
• Experience with Node.js and TypeScript in large production systems is a plus, but not required.

Responsibilities

• Set the long-term technical vision and architecture for backend systems powering experimentation, personalization, analytics, and conversion optimization across Webflow.
• Architect and evolve high-throughput distributed systems and APIs that ingest, process, and serve large volumes of visitor and event data with low latency, high availability, and strong consistency guarantees where it matters.
• Lead foundational platform investments and the data infrastructure that supports them, that unlock new product capabilities for years to come.
• 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.

• Wellness for the whole you. Access to mental health resources, therapy and coaching.
• Invest in your future. A 401(k) with 100% employer match (up to $6,000/year) in the U.S., and support for retirement savings globally.
• Monthly stipends that flex with your life. Localized support for work and wellness expenses — from Wi-Fi to workouts.
