Full Stack DeFi Engineer

Penny Works is a startup founded by seasoned finance and technology professionals. We believe in the power of blockchain technology to improve people’s financial lives and are aggressively building an automated digital asset bookkeeping service.

We’re looking for a full‑stack DeFi engineer, someone that has an understanding of DeFi, and can help us cater to the different protocols. You’ll have the opportunity to learn about all the data and services that power blockchain analytics, complex DeFi applications, and international accounting and tax considerations. We’re fully remote and have a fully flexible schedule. Get stuff done however you want.

This is an individual contributor role with opportunity to grow into leadership roles as we scale. You will report to the CTO and build out our core infrastructure. The basic architecture is already set up; we need help building out and expanding our coverage of blockchains and various protocols. You will also have significant input on how the product will evolve.

But please, leave your ego at the door (we have no doors, so you’ll have to be creative about it).

• To have worked for a DeFi start‑up or DeFi protocol
• Have at least 3‑5 years of development experience in Python, contributing to mission‑critical production systems. Familiarity with FastAPI and SQL Alchemy is a plus.
• Have strong coding standards and familiarity with operating in an Unix environment.
• Experience designing backend REST APIs.
• Experience building and supporting complex, scalable, distributed, event‑driven, microservices‑based applications with third‑party service integrations.
• Experience with relational database schema design, transactions, isolation levels. Working experience with Postgres is a plus. DB admin experience is a double plus.

• Experience with Google Cloud infrastructure
• Experience setting up and supporting Kubernetes clusters is a big plus
• Dev Ops, networking, Linux shell scripting
• Infrastructure‑as‑code – automated infrastructure management

• Are a “show, don’t tell” kind of person and are able to continuously improve your craft via measurable analytical feedback.
• Prefer saying “let’s try it out!” instead of “it’s been done, and it doesn’t work”.
• Plan ahead and stay on top of things, but don’t get flustered if it doesn’t go as planned (predicting the future is hard, we tried it).
• Are curious, love to learn, and love to share your knowledge.
• Must have demonstrated interest in crypto, although no professional experience in the area is required.
• Must be able to, and enjoy, working in a fast‑paced environment with frequent interruptions, changing priorities, and context‑switching.
