Job Description

Founding Backend Engineer (Platform) — Crypto Trading

Remote | $225-300K base + meaningful equity

We’re working with a small, highly experienced crypto team building a mobile-first trading platform for advanced, high-volume traders.

This is a true founding engineering seat. You’ll be one of three founding engineers and will own the core backend platform outside of money movement, taking the architecture from 0→1 and building systems designed to handle large data volumes, real-time market activity, and sudden traffic spikes.

What you’ll build

• Integrate market, pricing, wallet, and blockchain data from third-party APIs into a reliable backend
• Build in-house Solana and/or EVM blockchain indexing infrastructure
• Build WebSocket fanout for live prices, positions, and market data
• Design high-performance, cost-efficient data serving and caching using PostgreSQL and AWS/GCP
• Lead backend architecture and platform feature development alongside the founder and product lead

What we’re looking for

• Approximately 6–12 years of backend engineering experience; 8–12 is ideal
• 2–3+ years of recent crypto experience
• Experience building backend systems for a crypto exchange, DEX, wallet, brokerage, trading terminal, or similarly demanding product
• Strong production expertise in Rust or Go
• Hands-on experience indexing Solana or EVM on-chain data
• Experience with WebSockets / real-time data at scale
• PostgreSQL and AWS or GCP
• Strong 0→1 ownership and comfort working in a very small, highly autonomous engineering team

Experience with high-usage consumer trading products is a major plus.

Compensation: $225K–$300K base + approximately 1.5%–2% equity for strong candidates

Location: Fully remote across the US, Canada, Latin America, Europe, South Korea, and Singapore. NA/EU time zones preferred.

Visa: Candidates must already be legally eligible to work from their location; no visa sponsorship.
