职位描述

## The Role We’re seeking a senior engineer to lead backend trading systems and own DevOps across Docker, GitHub Actions CI/CD, and AWS ECS (Fargate). You’ll partner with founders on product strategy, solve complex distributed systems problems, and treat AI tools as core leverage. Frontend/mobile work is occasional; React Native familiarity is sufficient, deeper expertise is a plus. Experience with our exact stack is preferred. ## What You’ll Do - Lead backend development: Architect and build low-latency trading services in TypeScript/Node.js with Redis and MongoDB; deliver reliability, scalability, and strong observability. - Own DevOps: Containerize services with Docker, establish and maintain GitHub Actions CI/CD, and deploy/operate on AWS ECS (Fargate) with safe rollbacks and monitoring. - Design APIs and data models: Define REST and WebSocket API specifications (endpoints, message types, auth, rate limiting), and own schema design, indexing, migrations, and data lifecycle. - Distributed systems: Implement resilience (idempotency, retries, circuit breakers) and event-driven workflows. - Performance and security: Profile hot paths, optimize caches and queries, enforce secure coding, secrets/IAM hygiene, and compliance-minded data handling. - Code quality leadership: Drive reviews, testing strategy, and documentation; mentor peers; raise the engineering bar. - Product strategy: Turn ambiguous requirements into iterative roadmaps; communicate trade-offs; measure outcomes. - AI-native development: Use AI tools for implementation, testing, docs, and propose AI-powered features where valuable. - Frontend collaboration (as needed): Provide guidance or light contributions to React/React Native; basic RN knowledge is acceptable.
