Overview

About Oneleet

Oneleet is one of the fastest-growing security and compliance platforms in history. We are on a mission to change the compliance and security industry by making cybersecurity and compliance effective, easy, and painless. We provide a platform that helps companies build, manage, and monitor their cybersecurity programs and achieve compliance standards such as SOC 2 and ISO 27001 efficiently, without cutting corners. Having just raised a $33 million Series A, we are rapidly growing in customers and employees. Our team has decades of experience in security and compliance. Join our team of opinionated rebels and help us build a category-defining company reshaping the broken and fragmented compliance and cybersecurity industry.

Who we’re looking for:

We value passionate self-starters with a growth mindset and a bias for action and personal accountability. If you love solving hard problems, thrive in ambiguity, and want to make a real impact, you’ll fit right in. We’re especially drawn to:

Rebels with a cause — frustrated with the status quo and eager to disrupt it.
Opinionated (but not obstinate) builders — decisive yet collaborative, who help us move fast.
Clear communicators — who own their ideas and follow through.

Our mission is simple: make effective cybersecurity painless. We believe cybersecurity should empower, not burden. This belief unites our team and drives every decision we make. If you’re ready to challenge the status quo and help shape the future of cybersecurity, we’d love to meet you. As a Frontend Engineer at Oneleet, you'll own the user experience layer of our cybersecurity platform. You'll build the dashboards, workflows, and data visualizations that security teams use day-to-day — turning complex underlying data into clear, actionable interfaces. This is a hands-on, React-focused role at a Series A startup. You'll partner closely with our Product Designer and PM on a mock-up-first workflow — taking mock-ups and shipping them quickly without losing design fidelity. You'll extend our existing component library, push back when patterns don't hold up, and work directly with customers to validate what you ship. Working primarily in TypeScript and React, you'll help us ship a polished product against named competitors.

Key Responsibilities:

Build UI components and full pages in React/TypeScript across the platform
Extend and maintain our existing component library, ensuring consistency across the product
Implement complex triage, filtering, and workflow flows that handle high-volume data
Build data visualizations for dashboards, posture views, and reporting
Optimize frontend performance — list virtualization, smart pagination, responsive interactions on large datasets
Implement real-time updates where they matter
Partner with the Product Designer on mock-up reviews and on extending the component library
Work with fullstack and backend engineers to shape the APIs that power the UI
Build feedback loops and analytics that capture user interactions with new features
Work directly with customers and design partners to validate UX and iterate quickly

Qualifications:

5+ years of frontend engineering experience with deep expertise in React and TypeScript
Strong track record of shipping production UIs in modern frameworks
Hands-on experience working inside mature component libraries and design systems
Experience with state management, performance optimization, and complex data fetching patterns
Comfortable with data visualization libraries
Strong eye for design fidelity — comfortable pushing back on patterns or mock-ups when something doesn't hold up
Solid debugging skills in the browser and across the network boundary
Experience gathering requirements from users and translating feedback into UI improvements
Strong communication skills and comfort working directly with customers and design
Scrappy; prior startup experience and not afraid to get their hands dirty
Pragmatic; knows how to ship fast without unnecessarily complicating things
Experience in (and thrives in) a fast-moving, start-up engineering environment

Bonus:

Background in cybersecurity or developer tools
Experience with real-time data updates and WebSocket implementations
Experience designing or building accessible (WCAG-conformant) interfaces
Experience with end-to-end testing frameworks

You should apply if any of the following excite you:

Owning the user experience layer of a multi-product cybersecurity platform
Working mock-up-first alongside a strong Product Designer on tight iteration cycles
Building dashboards and visualizations that turn complex data into clear, actionable views
Shipping quickly against a clear competitive target without losing design quality
