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.

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., * 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 ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Microfrontends at Scale](https://www.wearedevelopers.com/videos/236-microfrontends-at-scale) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers)
