[Hiring] Software Engineer (Full-Stack) @Qompyl

Role Description

We’re looking for a Full-Stack Developer who can primarily lead back-end development while contributing to front-end features when needed. You’ll design and build scalable systems for a next-generation strategy-building platform, including high-performance APIs, real-time data services, and seamless integrations across the stack. This is a part-time, equity-only role suited for someone seeking a meaningful side engagement alongside full-time work or consulting projects.

Key Responsibilities

• Design, develop, and maintain back-end systems using Python, FastAPI, SQLAlchemy, and PostgreSQL.
• Build and optimize RESTful APIs, WebSocket integrations, and real-time data services.
• Integrate financial data providers (Alpaca, Yahoo Finance, Alpha Vantage) for live and historical data.
• Improve performance across large datasets, strategy simulations, and live market flows.
• Contribute to front-end development using React and TypeScript.
• Participate in data modeling, schema design, and platform architecture.
• Build and maintain containerized applications using Docker and collaborate via Azure DevOps for pipelines and sprints.
• Maintain clear documentation, code quality, and Git/GitHub workflows in a global async-first environment.
• Foster a healthy, respectful, and collaborative team culture.

Qualifications

• Strong experience with Python, FastAPI, SQLAlchemy, and relational databases (PostgreSQL preferred).
• Familiarity with Pydantic, RESTful API design, WebSockets, and real-time data patterns.
• Exposure to React and TypeScript for occasional front-end contributions.
• Ability to integrate external APIs and work with financial data providers.
• Solid understanding of Git, documentation practices, and collaborative workflows.
• Experience with Docker; familiarity with CI/CD or Azure DevOps is a plus.
• Understanding of mobile application architecture principles (mobile-first, performance, state management); exposure to Flutter or mobile-backend integration is a strong plus.
• Comfortable working in a remote, async, high-ownership environment.
• Curious, adaptable, and motivated to build tools that simplify complex workflows.

Requirements

• This is a part-time, equity-only role suitable as a side engagement alongside a primary job or consulting work.
• The position will transition to compensated status after the MVP launch and once funding or sustainable revenue is secured.
