About the Role

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.

This is a remote position (North America) reporting to the Chief Technology Officer, giving you high visibility and influence across the business.

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.
