Frontend Developer

About us:

The physical and digital worlds are merging. Vehicles, medical devices, industrial systems, critical infrastructure: security hasn’t kept pace. AI is accelerating everything, from the capabilities of the systems we depend on to the sophistication of the threats targeting them. A software vulnerability can now have physical consequences. A physical breach can compromise entire digital ecosystems. Billions of devices operate with little to no protection, and traditional approaches can’t keep up. Not at this scale, not at this speed, and not across this diversity of systems.

Exein exists to solve this. We build the security layer for a world where physical and digital threats are no longer separate problems, from kernel-level runtime protection on embedded devices to cloud-native platforms that analyze, protect, and prove compliance across entire device fleets. We’re not patching the old model. We’re building security from the core out.

Job Overview

We are seeking a Frontend Engineer to join our team, working on the development of secure, high-performance web applications. You will build modern, responsive user interfaces while also architecting scalable systems using React, Next.js, and TypeScript to handle real-time threat telemetry and mission-critical security workflows.

In this role, you will collaborate closely with designers, backend engineers, and product teams to deliver intuitive, reliable user experiences, write clean and maintainable code, and contribute to key technical decisions. The ideal candidate combines strong frontend expertise with a passion for performance, scalability, and building user-centric interfaces in complex environments.

Responsibilities:

• Design and implement scalable, modular frontend architectures that support complex data visualizations and multi-tenant security environments.
• Work on the development of a robust, accessible, and reusable UI component library to ensure consistency across all platform modules.
• Optimize deep-stack performance, from Next.js SSR strategies to minimizing Time to Interactive (TTI) for data-heavy dashboards.

Requirements :

• You have 3-5 years of experience working with React, Next.js, and TypeScript; experience in deep tech or cybersecurity companies is strongly preferred.
• You leverage AI tools (e.g., Cursor, Claude) and have invested time in mastering prompt engineering and workflow integration.
• You know exactly when an AI-generated output is hallucinating or insecure, and you have the expertise to refactor and fix it.

Why Join Us?

• Build technology that helps organizations detect and respond to real-world cyber threats.
• Work in a modern development environment that embraces AI tools to increase productivity and focus on high-impact technical challenges.
• Join a team of experienced engineers, security specialists, and product leaders who value knowledge sharing and technical excellence.
• Be part of a rapidly growing cybersecurity scale-up where your ideas, ownership, and innovation directly influence the product and its future.
