Founding Platform Engineer

Description We are hiring on behalf of our client, a fast-growing innovator in the crypto and decentralized finance space who is seeking a Founding Platform Engineer (Staff+ level) to join the team. This organization is behind a leading decentralized exchange (DEX) on HyperEVM, having achieved significant revenue milestones with an ultra-lean team. The client is now expanding its technical architecture to build an advanced, mobile-first crypto trading platform (spot + perps) alongside a novel, original social product featuring cutting-edge mechanisms.

As the first and only engineer in this specialized domain, the incoming candidate will take an original product vision and turn it into a robust, high-performance system—holding the entire architecture and the smallest details simultaneously. The operational environment is primarily asynchronous, highly independent, and built for top-tier developers who can scale infrastructure from zero to massive daily trading volumes while maintaining absolute reliability.

Requirements

• Platform Ownership: Own the core platform, including the data layer, rewards engine, notifications, the API surface, and overall system reliability.
• Trading Engine Integration: Integrate perpetual trading engines through Hyperliquid, alongside spot trading via Jupiter and Relay.
• Data Harmonization: Aggregate and unify conflicting data providers (such as Zerion, CoinGecko, Mobula, Alchemy, and Hyperliquid) into a single, cohesive source of truth.
• High-Performance Data Delivery: Serve heavy data rapidly by implementing resilient caching mechanisms that survive traffic stampedes and fan-out structures that hold under pressure.
• Cross-Chain Abstraction: Design architecture that makes a single USDC balance across multiple chains entirely invisible and seamless to the end user.
• Peak Performance & Reliability: Maintain absolute uptime during peak market volatility.
• ensure the application never lags or crashes when it matters most, guaranteeing users can always close positions.RequirementsProven track record of engineering resilience, including keeping a high-stakes system alive through massive traffic spikes and determining graceful degradation strategies in advance.
• Extensive experience building financial rewards and accounting systems that withstand retries, prioritizing idempotency, replay safety, and precise lot tracking.
• Deep understanding of end-to-end latency budgets (from a user's tap to screen rendering).
• Advanced database optimization skills, capable of resolving bottlenecks directly within PostgreSQL rather than relying on secondary databases.

Benefits

• Competitive Compensation: Top-market base salary paired with significant equity upside. Flexible & Remote-First Work: 100% remote working model with flexible schedules and high operational autonomy.
