Das ist der Job

Few engineers.

Darum lohnt es sich

You’ll build interfaces that verify cryptographic attestation evidence directly in the browser using Rust and WebAssembly, orchestrate long-running secure computations while keeping the UI responsive, turn differentially private data into interactive visualizations and build on top of our growing 60+ component design system. /ppWe’re looking for an exceptional bSenior Frontend Engineer (≥80%, start ASAP) /b who wants to own these kinds of engineering challenges end-to-end in a hybrid, on-site role in Zürich. /ppWe believe in a bsmall, high-leverage engineering team with end-to-end ownership /b.

You carry your work from idea to production. /lilibState management for interactive data applications: /b Tackle complex state-management challenges in a modern, data-intensive environment.

Leverage bWebAssembly /b to accelerate computationally intensive tasks, and build rich, interactive visualizations that turn raw data into intuitive, user-friendly insights. /lilibAI-powered productivity: /b Leverage LLM-based code assistants, design generators and test-automation tools to move faster and raise the quality bar — and share your workflows with the team. /lilibCollaborate across the company: /b Work shoulder-to-shoulder with bdesign /b, bproduct /b and bengineering /b.

On a small team, your voice shapes the product directly. /li /ulh3Requirements /h3ulli(Must have) Bachelor (or higher) Degree in CS or similar and 3+ years of professional experience /lili(Must have) Good communication skills with fluency in English /lili(Must have) Extensive experience in TypeScript, React, CSS3 and HTML5 /lili(Must have) Based in or willing to relocate to Zürich (3 days/week on-site) /lili(Must have) You use AI-assisted development tools effectively while maintaining high engineering standards.

We’re continuously investing in our AI development stack to build a compounding engineering advantage that helps our small team compete with much larger companies. /lili(Must have) Proven record of building data-heavy UIs that stay responsive through smart state management and memoisation /lili(Plus) Experience with web applications involving heavy data processing (e.g. wasm) and visualization (e.g.

D3.js, Chart.js, Recharts) /lili(Plus) Technical leadership experience /lili(Plus) Willingness to pick up some Rust for simple backend changes /li /ulh3Benefits /h3ulliJoin a small engineering team where every engineer owns meaningful product areas and directly shapes the company’s direction. /liliWork on unusually challenging frontend problems spanning WebAssembly, large-scale state management, data visualization and privacy-preserving technologies. /liliHelp build one of the industry’s most AI-native engineering organizations /liliCompetitive salary /li /ulpNo need for a formal motivational letter. ppDecentriq builds the bprivacy-preserving infrastructure /b that lets advertisers, retailers and publishers collaborate on first-party data for audience targeting and campaign measurement — without exposing their underlying data.

Headquartered in Zürich, we’re trusted by industry leaders such as RTL Ad Alliance, Publicis Media, The New York Times and major Swiss banks.

We’re helping define how data collaboration works in a privacy-first world. /ppOur bweb application is the primary interface to this platform. /b Built with bReact /b, bTypeScript /b, bGraphQL /b and bJoy UI /b, it lets customers configure secure data jobs, explore results, activate audiences to every major destination and trigger ML workflows with a single click. /ppbThis isn’t another CRUD-over-an-API frontend role /b.

You’ll own features from the idea through implementation and production, and leverage AI-assisted development to ship faster while maintaining a high engineering bar. Large product surface. Real ownership.

Real impact. /ppIf you’re excited by building technically ambitious frontend software that solves real privacy and data engineering challenges, we’d love to hear from you. /ph3Tasks /h3ullibOwn features end-to-end: /b Design, build and ship full-featured client-side applications with React and Joy UI — responsive, polished interfaces backed by a mix of GraphQL and REST APIs.

Design scalable solutions that keep the client application efficient, responsive and maintainable, even under heavy data loads. /lilibClient-side data processing visualization: /b Implement and optimize advanced client-side data processing directly in the browser.
