Helius is building the foundational infrastructure for Solana - empowering developers to create the next generation of crypto-powered applications. Our mission is to accelerate the development of internet capital markets by making it easier, faster, and more intuitive to build on-chain.
Thousands of teams, from startups to industry leaders like Coinbase, Phantom, and Jupiter, rely on Helius APIs, webhooks, and indexing tools to power their products. Backed by Haun Ventures, Founders Fund, and Foundation Capital, we’re a small, senior team building at the intersection of performance, usability, and decentralized systems.

About the RoleWe’re forming a small, high-impact team at Helius to explore how people interact with on-chain data and financial systems.
You’ll be among the first engineers on a stealth initiative reshaping how people interact with on-chain financial systems. You’ll build sleek, lightning-fast interfaces for real-time data and reimagine how developers, traders, and institutions engage with markets.
This is a rare opportunity to work directly with our founders and product leadership — owning the front-end experience from concept to production and helping define the visual language of a new class of financial products.
What You'll DoBuild sleek, responsive UIs for a data-heavy, real-time application
Collaborate closely with product, design, and engineering leaders to shape the vision and architecture
Prototype and iterate quickly - experimenting with new patterns, interactions, and frameworks
Push the limits of what’s possible in performance, usability, and visual polish
Help define and evolve our design system for a new class of web3 products
4+ years of experience building world-class front-end applications (React, TypeScript, Next.js, or similar)
Deep care for design, motion, and micro-interactions — you sweat the details
Experience creating high-fidelity, data-rich interfaces (dashboards, terminals, analytics tools, etc.)
Ability to thrive in ambiguity and take ideas from concept to launch with minimal guidance
Strong product intuition and a bias toward simplicity and speed
Open-source contributions or side projects that showcase exceptional UI craft
Experience at design-obsessed companies (e.g. Apple, Robinhood, Stripe, Figma, Notion)
Background in data visualization, streaming systems, or trading platforms
