Senior Software Engineer (Python and Solidity)
Python Software Foundation, Florida, New York, United States
Senior Software Engineer (Python and Solidity)
Job Description
What You’ll Be Doing Develop Python services and APIs that tie blockchain infrastructure to the “real world.” Build and ship smart contracts in Solidity that power mortgage tokenization. Obsess over security, reliability, and scalability. Help shape our architecture and technical roadmap. Collaborate directly with product, compliance, and ops — we’re small, so everyone has a big voice. Mentor teammates and bring best practices to everything we ship. A Day in the Life You’ll be wearing multiple hats — one minute you’re developing a Solidity contract to manage payments, the next you’re debugging a Python API that feeds data into the blockchain, then pairing with product to brainstorm a new feature, and finally debugging celery tasks to make them faster. You’ll own features end-to-end, from design to deployment, and jump into whatever part of the stack needs your expertise. Every day is hands-on; every day you make a visible impact. Our Stack Backend: Python (Django, Django Rest Framework), Celery, RabbitMQ, PostgreSQL Smart contracts: Solidity, OpenZeppelin, Hardhat/Foundry Infrastructure: AWS, Docker Blockchain: EVM-compatible chains Integrations: Web3.py, analytics Requirements 10+ years building products, with serious chops in Solidity and Python. Experience developing smart contracts (EVM-compatible). Expert with Python tools and frameworks (Django, DRF, Celery). Strong experience working with distributed systems involving multiple connected components and asynchronous programming. Strong grasp of blockchain fundamentals, DeFi, and token standards (ERC-20, ERC-721, ERC-1155). Bonus: exposure to financial services, mortgages, or asset-backed tokens. We’re a fintech startup on a mission to reimagine the life of a mortgage through blockchain. By tokenizing real estate debt, we’re building a platform that makes the investing in mortgages more transparent, accessible, and liquid. We are an equal opportunities employer and welcome applications from all qualified candidates.
