Software Engineer at Coinpilot

Job Description

Key Responsibilities

• 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

• 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.

Preferred Qualifications

• 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.

Technology 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

Work Culture

• 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 Expectations

• 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

• Flexible working hours
• Remote work options
• Equity/tokens compensation
