Full Stack Engineer; Frontend-Led

SCRYPT is a Swiss-based institutional digital asset partner behind firms starting or scaling their digital asset journey. Headquartered in Zug, we combine market access, proprietary technology, and Swiss regulatory oversight to enable institutions trade, custody, and invest in digital assets with confidence.

We serve banks, brokers, fintechs, payment service providers, family offices, asset managers, hedge funds, crypto projects, and commodity traders – institutions that require high-performance execution and a trusted partner for digital assets.

We're building customer-facing crypto and trading products that need to feel fast, trustworthy, and intuitive, in an industry where most interfaces are either overwhelming or underwhelming. We’re looking for a full stack engineer who lives primarily on the frontend but isn’t afraid of the backend. You will own the end‑to‑end experience of what users see and interact with: trading dashboards, portfolio views, compliance‑facing reports, and internal operational tools.

This means working directly with Type Script and React to build interfaces that handle real‑time data, complex state, and high‑stakes financial information without breaking a sweat. You have a strong eye for what makes a UI feel right in a financial context, data density, latency perception, error states that don’t panic users, and you bring the same rigour to frontend architecture that a backend engineer brings to API design.

Experience with data visualisation libraries (D3.js, Recharts, Plotly) is a strong plus – we have a lot of data and users who need to understand it quickly.

You’re full stack in the practical sense: you can build and own a Node.js API when the feature requires it without needing someone else to do the plumbing. You understand how blockchain data sources work, pulling from APIs like The Graph or Dune Analytics, and you know the difference between what the chain says and what the user needs to see.

You have working knowledge of identity and access management (OAuth 2.0, OIDC, MFA) because auth in a crypto platform is not an afterthought. You’re comfortable with event‑driven patterns and understand why a trading UI that polls every second is a different problem than one that subscribes to a real‑time stream. You think about portfolio metrics, risk display, and mandate constraints not as abstract requirements but as real decisions that affect how users trust the product.

You take ownership of what you ship beyond just writing the code. You care about how a feature performs in production (latency, rendering, error rates) and you know how to investigate when something feels off. You use AI coding tools (Copilot, Cursor, or equivalent) to move faster, but you treat generated UI code with a critical eye, knowing that a component that looks right can still have broken state logic, accessibility issues, or edge cases that only show up with real financial data.

You’re fluent in English, written and spoken, because this role involves working closely with compliance, legal, and operations stakeholders who need to understand what’s being built and why. You thrive in environments where the requirements are sometimes ambiguous, the pace is real, and ownership means more than just closing tickets.
