Job description

We're looking for a Senior Frontend Engineer who thrives in early-stage environments and loves building UIs from the ground up. As the first frontend hire, you'll take full ownership of the UI layer of a cloud-native platform: dashboards, reporting, inventory management, and core user flows. This is a greenfield project: you'll be building everything from scratch with no legacy or pre-built code.

You'll work closely with the Software Architect, Full-Stack Engineer, and Cloud Deployment Engineer to turn wireframes and requirements into polished, performant user experiences.

Responsibilities

What you’ll own.

• Bootstrap, design, and build modern, responsive UIs using frameworks like React, Vue, or similar.
• Take ownership of the entire frontend codebase, architect the frontend for scalability, reusability, and maintainability.
• Collaborate with backend engineers to integrate APIs securely and efficiently.
• Define and enforce UI architecture, component structure, and optimize front-loading data and state-management strategies.

UX & design thinking

• Design intuitive and user-friendly interfaces for complex security workflows and dashboards.
• Apply design systems, accessibility best practices (WCAG), and consistent UX patterns.
• Work closely with product and customers to translate complex requirements into elegant experiences.
• Collaborate with product managers to shape features, prototypes, and flows.
• Identify UX and UI improvements based on customer feedback and usage data.
• Contribute to defining frontend testing strategy and CI/CD processes.
• Mentor junior engineers as the team scales.

Required Skills

What you’ll bring day one.

Core

• 4+ years of frontend development experience with at least 2 years in a senior or lead role.
• Expertise in Next.js (preferred) and React with deep understanding of hooks and state management (Redux, Zustand, etc.).
• Experience with TypeScript, component-driven development, and design systems.
• Strong grasp of HTML5, CSS3, SCSS, and responsive design techniques.
• Comfortable with RESTful and secure APIs, including OAuth2 / OIDC integration. Working with Auth0 SDKs or similar SDKs is an asset.
• Comfortable building Login and Logout flows.
• Solid understanding of frontend security practices (XSS, CSP, CORS).
• Experience building admin consoles, dashboards, or SaaS web apps.
• Familiarity with frontend testing tools (Jest, Cypress, Playwright).
• Hands-on experience with CI/CD for frontend and modern build tools (Vite, Webpack).

Nice to Have

• Experience working in security, cryptography, or developer tools.
• Familiarity with Figma, Storybook, or UI design systems for design collaboration.
• Understanding of accessibility standards and browser performance tuning.
• Exposure to Kubernetes, Docker, and how frontend fits into modern DevOps pipelines.
• Prior experience owning a product end-to-end in a startup or early-stage environment.

Who You Are

• You care deeply about user experience and constantly think from the user's perspective.
• Implementation mindset: you love writing code to test architectural components.
• You're a self-starter who takes ownership and pushes features from concept to production.
• You're collaborative, open to feedback, and comfortable working in a cross-functional, remote-first team.

Why Join Us

• Remote & flexible: work from anywhere.
• Fast-paced, no red tape: move quickly, own decisions, drive real change.
• Collaborate with industry leaders in cyber security.
• High-impact role: design and develop UI architecture for a cutting-edge NHI platform.
• Growth opportunity: exposure to product architecture, automation, and DevOps best practices.
