Staff Backend Engineer - High-Scale DeFi Social Trading API
Location:
Remote - NY preference but open to US remote Compensation:
$180K - $250K We are a well-funded startup building the
global trade comment network —a core protocol that solves the trading discovery problem by connecting traders across different applications. Our solution allows users to comment on their trades (the "why") and earn a percentage of the copytrades they drive. We are seeing a massive increase in market size as traditional exchanges and fintech apps adopt decentralized trading. We are looking for a
Staff Backend Engineer
with deep experience designing and scaling REST APIs to manage data flow for millions of users. You will be responsible for designing and scaling the API that serves tens of thousands of requests per second, summarizing millions of rows of off‑chain data and terabytes of on‑chain data in 500ms or less. This role requires solving core software engineering challenges, focusing heavily on performance, code maintainability, and infrastructure optimization. Key Responsibilities: API Design & Scaling:
Design robust
backend REST APIs
for usability and massive scale. Performance Optimization:
