- You bring 7+ years of application security experience, including hands-on software development, and have operated as a technical authority in securing high-complexity, large-scale applications
- You have deep expertise in secure software design, secure coding, and modern web application security, with a proven ability to identify security design flaws and complex business-logic vulnerabilities, and to drive risk-based remediation with engineering teams
- You regularly lead threat modeling efforts, conduct and oversee advanced penetration testing, and manage third-party pentests, ensuring findings are clearly documented, communicated, and remediated to completion
- You have designed, implemented, and evolved software supply chain security programs, and have owned or led bug bounty programs and major security tooling initiatives, shaping strategy rather than acting solely as a contributor

- You have driven multi-quarter application security roadmaps and complex security programs, partnering with engineering, product, and platform teams to deliver durable security outcomes

- You have experience using and building security solutions that leverage agentic AI, including applying AI coding agents to scale security reviews, detection, and automation responsibly
- You have participated in and led response efforts for application security incidents, from triage and containment through remediation and post-incident improvements
- You actively mentor and elevate other application security engineers, and help foster strong security practices and judgment across engineering organizations
- You are passionate about security, continuously learning, and able to clearly explain complex security concepts to technical and non-technical partners to drive alignment and action
- Stay curious and open to growth — actively building fluency in emerging technologies like AI to unlock creativity, accelerate progress, and amplify impact

- Bring security best practices to the software development lifecycle
- Work as part of a team to champion security standards while balancing business strategies and requirements

- Work to find security vulnerabilities through grey-box techniques, and propose solutions at the architecture and code level to mitigate findings
- Contribute code and architecture improvements to enable security within Webflow’s application for engineers
- Cross-train entry and mid-level application security engineers
- In addition to the responsibilities outlined above, at Webflow we will support you in identifying where your interests and development opportunities lie and we'll help you incorporate them into your role
Application process
- Application deadline: applications accepted on an ongoing basis until position is closed and filled

Our take
Webflow is an AI-native web experience platform that enables teams to design, build, manage, and optimize high-performing digital experiences across the entire website lifecycle — from creation to conversion — without relying on fragmented tools or constant developer handoffs.
Unlike traditional website builders or legacy CMS platforms, Webflow combines visual development, content management, optimization, analytics, localization, governance, and enterprise-grade hosting into a single, integrated system. This allows marketing, design, development, and growth teams — and increasingly AI agents — to collaborate in one shared environment while maintaining brand consistency, security, and control.
Built for a world where websites must perform for both humans and AI systems, Webflow helps organizations stay discoverable and relevant as search, personalization, and content consumption evolve. Native AI capabilities are embedded directly into core workflows, accelerating everything from site creation and content updates to experimentation, personalization, and AEO (AI Engine Optimization).
Today, over 3,000 organizations — from startups and agencies to global enterprises including Dell, Spotify, Dropbox, and Upcwork — use Webflow to build brand-forward digital experiences that drive measurable business results. With a strong partner ecosystem, enterprise adoption momentum, and more than $330M in funding, Webflow is redefining how modern teams build and scale on the web.
Rather than replacing developers, Webflow shifts development effort to where it matters most — freeing teams to move faster, operate more efficiently, and evolve their digital presence without replatforming as their needs grow.
