Senior Full-Stack Engineer (Trading Platform)

Remote work

Flexible Schedule

Full time

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.

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.

Requirements

5+ years of engineering experience
Comfortable across backend systems, including low-latency backend
Experience with modern frontend frameworks ( React 18+ / TypeScript)
Active trader: futures or crypto, day trading or scalping
Spec-driven, AI-orchestrated development: you plan deeply and know how to work with AI agents effectively
Experience with real-time market data: WebSocket streaming, order books, Level 2 depth
Ability to produce your own product specs
Ability to make UX decisions based on the UX guide and input from a UX advisor
Fluent English (written and spoken)

Would be a plus

Ruby and Rust (we use Rust/Axum) experience
Experience with high-performance browser rendering (e.g. WebAssembly, ImGui, egui)
Familiarity with trading tools like footprint charts, DOM/ladder, heatmaps, market/volume profile, CVD
