Reports toChief Product Officer
§ About the Role

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.

UI development & architecture

  • 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.

Collaboration & product ownership

  • 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.
