- CI/CD & infra: Containerization (Docker), automated tests/deploys, IaC, secure secrets, staging/prod parity, cost-aware cloud.
- Security & privacy: non-custodial flows, wallet interactions, principle of least privilege.
- Roadmap collaboration: signal-provider marketplace, CEX integrations.
Representative Technologies
- Backend:Â Node.js (TypeScript, Node 20), Python (async workers), WebSockets/REST, Postgres, Redis/queues.
- Frontend: React Chrome Extension APIs, content scripts, overlay UI. NextJs
- Cloud & DevOps: AWS (VPC, ECS (EC2), RDS), Docker, Terraform/CDK, GitHub Actions, Sentry/PostHog/Grafana.
- Trading/Web3: Hyperliquid APIs (HyperCore), wallet flows, signing; additional exchange APIs later.
Qualifications
- 5+ years building and operating production systems end-to-end in startup environments.
- Self-starter with founder mindset: clarify, design, ship, measure, iterate.
- Strong in Python and Node.js/TypeScript; comfortable context-switching across the stack.
- Hands-on across backend, CI/CD, cloud infra, and frontend.
- Pragmatic testing: unit/integration, load testing for execution paths, telemetry-first approach.
- Solid engineering hygiene: reviews, documentation, security, and calm debugging under pressure.
Bonus Experience
- Blockchain engineering (wallets, signing, EVM/HL or similar) and/or financial markets/exchange systems.
- Chrome extension performance & permission model expertise.
- Low-latency systems, back-pressure, numeric stability (PnL/ATR/RR).
- Zero-to-one product launches and ownership of on-call.
