Job Description:
## About Coinpilot
Coinpilot is at the forefront of decentralized finance. We're a VC-backed startup building a **mobile-first copy trading platform on Hyperliquid**, with a long-term vision to introduce a full suite of on-chain investment strategies.
Our team brings years of deep Web3 experience to the table, and we're looking for passionate builders to join our mission. This is a ground-floor opportunity to create a category-defining product in one of the fastest-moving spaces in tech.
## 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.
Job Requirements:
## What You’ll Bring
- 6–10+ years building and operating production backends with end-to-end ownership.
- Deep expertise in TypeScript and Node.js in production environments.
- Redis proficiency (caching, locks, pub/sub) and strong MongoDB experience (schema/index design, performance, aggregation).
- Real-time systems experience: WebSockets/streaming, event-driven patterns, consistency and reliability at scale.
- DevOps: Docker; CI/CD (GitHub Actions), AWS ECS (Fargate), environment promotion, blue/green or canary, metrics/alerts, cost awareness.
- Security: AuthN/AuthZ, secret management, least-privilege IAM, OWASP awareness.
- AI tooling: Proficient with AI coding assistants, test generation, doc automation, and pipeline accelerators; strong prompt craft.
- Collaboration: Clear communication, product empathy, high ownership, bias for action
## Nice To Have
- React Native (TypeScript), mobile CI/CD, store releases.
- Financial/trading or crypto experience; low-latency systems.
- Exchange API trading experience (e.g., Hyperliquid REST/WS, order signing/nonce management, rate limits, order lifecycle); familiarity with other exchange APIs (e.g., Binance, Bybit) is a plus.
- IaC (Terraform or AWS CDK); observability stack (CloudWatch, Sentry).
- Monorepo experience with pnpm workspaces and shared packages
## Our Stack
- Languages/Frameworks: TypeScript, Node.js; React/React Native (familiarity sufficient)
- Data/Infra: Redis, MongoDB, AWS ECS (Fargate), Docker
- CI/CD: GitHub Actions
- Tooling: pnpm workspaces, linting/testing, health checks and logging
## How We Work
- Ownership: You design solutions and drive them to production.
- Quality: Strong standards for code, tests, and documentation.
- Fast iteration: Small PRs, frequent deploys, data-informed decisions.
- AI-native: AI tools as core leverage to build better, faster.
## First 90 Days
- Deliver a production backend trading capability with strong reliability and observability.
- Establish GitHub Actions CI/CD pipelines and ECS (Fargate) deployments with safe rollbacks and monitoring.
- Improve system performance and security posture; document critical paths.
- Introduce AI-driven improvements that reduce cycle time and defects.
- Optionally provide guidance or small contributions to the mobile app
Benefits:
remote or on-site (hybrid); flexible hours; equity / token options
