Since our inception in 2014, founded by a team of scientists from CERN, we have dedicated ourselves to providing free and open-source technology to millions worldwide, ensuring access to privacy, security, and freedom online.

Our journey began with Proton Mail, the largest secure email service globally, and has since expanded to include Proton VPN, Proton Calendar, Proton Drive, and Proton Pass. These tools empower individuals and organizations to take control of their personal data, break away from Big Tech’s invasive practices, and defeat censorship. Our work impacts hundreds of millions of lives, from activists on the front lines defending freedom to leaders in governments protecting sensitive information.

About Lumo

Lumo is Proton's privacy-first AI assistant that fundamentally reimagines how AI should work - empowering users without exploiting their data. Unlike traditional AI platforms that harvest user conversations for training and profit, Lumo operates with zero-access encryption, keeps no server-side logs, and ensures that conversations remain completely confidential.

Built by the team behind Proton Mail, Proton VPN, and backed by the nonprofit Proton Foundation, Lumo represents a paradigm shift in AI development. We believe the benefits of AI are too great to miss, but the privacy risks of current implementations are too serious to ignore. Lumo is based on open-source language models, operates from Proton's European datacenters, and provides unprecedented transparency in the AI space.

Our Mission: To deliver the full power of artificial intelligence while maintaining user privacy as an uncompromising core principle. We're building an AI that only works for you, not the other way around - where your conversations remain confidential and your data stays fully under your control, never shared, sold, or stolen.

Our Technology: Lumo implements multiple layers of encryption throughout the entire pipeline, from device-to-server communication through to long-term storage, creating a privacy architecture that's simply much stronger than anything else on the market. The platform runs on open-source models including Mistral's Nemo and Nvidia's OpenHands 32B, with full source code transparency.

Role Summary

We are seeking a passionate and skilled Frontend Engineer to join our growing Lumo AI team. You’ll work across all functions of Lumo, turning designs into responsive, fast and reliable interfaces. Your code will shape the day‑to‑day experience of users, making it smoother, clearer, and more enjoyable.

Full Stack Engineering
Create, evolve and sustain high‑performance features that tie together the front‑end and back‑end layers of our modern stack. Ensure every component scales smoothly and integrates cleanly.

What You Will Do

• Optimize performance so pages load instantly even on slower connections.
• Collaborate closely with product managers, designers and other engineers to ship features end to end.
• Own the quality of your work: write tests, document decisions and participate in code reviews.
• Spot friction in the user journey and fix it before it becomes a complaint.

What we expect

• Strong expertise in React.
• Solid grasp of TypeScript and JavaScript fundamentals.
• Experience with state‑management and data‑fetching libraries.
• Ability to produce clean, maintainable code without cutting corners.
• Good communication skills and a willingness to give and receive honest feedback.

About the Role

We are seeking a Senior Software Engineer who will primarily lead the development and evolution of the Appier Web SDK, while also contributing to frontend web UI development for enterprise-facing web applications.

This position combines deep JavaScript engineering with frontend application development. You will work on improving the reliability, performance, and extensibility of Appier Web SDK, while also contributing to frontend architecture for enterprise-facing SaaS applications.

Responsibilities

• Lead the long-term evolution of Appier’s Web SDK architecture, strengthening its scalability, modularity, and maintainability to support future product growth

• Continuously improve runtime performance, bundle efficiency, browser compatibility, and overall stability in diverse client environments
• Contribute to frontend application architecture for enterprise-facing web products, ensuring performance, consistency, and maintainability across shared components
• Identify technical debt and architectural risks early, and proactively implement sustainable improvements rather than short-term fixes
• Safeguard quality through thoughtful testing strategies and thorough code reviews, helping maintain a strong engineering culture
• Support production stability by investigating and resolving client-side issues when needed
• Participate in product and technical roadmap discussions to ensure the SDK platform evolves in alignment with business and platform strategy

About You

• Deep understanding of browser internals, DOM, HTTP, web standards, and client-side performance optimization
• Experience designing or maintaining JavaScript SDKs, libraries, or shared frontend modules
• In-depth knowledge of front-end frameworks and technologies (e.g., React.js, Vue.js) and their ecosystems.
• Solid knowledge of version control (Git) and CI/CD workflows
• Experience writing unit, integration, and end-to-end tests
• Strong problem-solving skills and ownership mindset
• Self-motivated, proactive, and able to collaborate effectively in cross-functional teams
• Experience leveraging AI-assisted development tools (e.g., GitHub Copilot, Cursor, Windsurf) to accelerate coding, debugging, and refactoring. Familiarity with these tools is expected as part of our team’s daily development workflow.
• Passion for clean code, scalability, and performance, curious about new technologies and enthusiastic about developer experience
  
  

[Preferred qualifications]

• Familiarity with modern build tools and bundlers (e.g., Babel, Webpack, Vite, Rspack, esbuild, etc.)
• Experience in Node.js, Python, GraphQL, and integrating with various backend services and databases (e.g., MySQL, MongoDB)
• Experience with testing frameworks such as Jest, Vitest, Playwright, or similar
