Senior Product Engineer (Full Stack) – Trading Systems + FinTech Tools

We are building a suite of trading tools and financial products used by serious traders and investors with advanced analytics and interactive tools. This is not a typical development role. You will be taking ownership of multiple live systems and helping evolve them into scalable, production-grade products. The systems include a real-time trading signal platform with data ingestion, backtesting, and dashboards, rule-based algorithm engines, charting platform, and document generation tool powered by LLMs with structured logic and outputs. Some of these products share infrastructure including APIs, databases, reporting systems, and cloud deployment. This role is focused on turning high-level ideas into working systems quickly. You should be comfortable designing clean, modular architecture, improving existing codebases, and making technical decisions without needing detailed specifications. You will work directly with the founder in a fast feedback loop where strategy is translated into execution. Strong experience with Python, APIs, JavaScript, React, and LLMs is expected. You should also be comfortable working with databases, cloud environments such as AWS or DigitalOcean, and handling data-heavy applications. Experience with trading systems, market data, or backtesting is a major advantage. This is not a fit for developers who need detailed instructions or are only experienced in isolated frontend or backend work. We are looking for someone who has built complete products, understands systems end-to-end, and can move quickly with a high level of ownership. When applying, include a few examples of products you have built end-to-end and briefly explain how you would approach structuring a trading signal system that ingests data, generates signals, and delivers them to users.
