You’ll join us as a Senior Full-Stack Engineer, with your main focus on TradeZella, our trading journaling and educational platform. TradeZella syncs trade data from over 500 brokers and prop-firm platforms, runs backtesting against more than a decade of historical market data, and uses AI to automatically tag and analyze trading patterns for over 50,000 active traders.
We’re currently considering an allocation across two products, so there’s a chance you’ll also spend some time working on a trading terminal, a platform for reviewing and replaying trades designed for prop firms and traders. It combines order flow visualization with replay, audit, and execution in one system. TradeZella will remain the main focus of this role.
We work in a spec-driven way: we plan before we build. If you’re a senior engineer who actively trades and cares about building better trading tools, this role is for you.
What you’ll get:
🔸 Ownership — you’ll be involved in the full process: from specs to shipping. No ticket queue.
🔸 Product connection — you’ll use the product yourself as a trader.
🔸 AI-first team — we use AI as part of how we plan, research, and build, not just as a helper tool.
🔸 Working style — outcome-driven. We combine synchronous collaboration with focused asynchronous work, choosing the approach that best supports effective outcomes.
❕ Who we’re looking for
A senior full-stack engineer who is also an active trader. This role requires both strong engineering skills and real trading experience.
If you only code or only trade, this is probably not the right fit. We’re looking for someone who is comfortable working across product, technology, and trading.
