UI Engineer, Experiments at Helius, Remote (United States)

We’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 Do:

• Build 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

What You’ll Bring:

• 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

Even Better

• Experience at design-obsessed companies (e.g. Apple, Robinhood, Stripe, Figma, Notion)
• Background in data visualization, streaming systems, or trading platforms
• Familiarity with Solana or blockchain infrastructure

Why Helius?

• High-impact work: Your code will power applications used by millions across the Solana ecosystem – including Coinbase, Phantom, and Jupiter
• Design-driven culture: We care deeply about craft, polish, and performance – every detail matters
• Small team, huge scope: Join a lean, senior team where you’ll have outsized ownership and influence from day one
• Cutting-edge tech: Build with React, TypeScript, Next.js, Go, and Solana – plus get hands-on exposure to real-time blockchain data
• Remote-first flexibility: Work where you’re most productive, with flexible hours and a globally distributed team
