Senior Full-Stack Engineer (TradeTerm)

We’re building 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.

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.

The team

We’re a small founding team: 2 co-founders and 1 engineer (you would be the second), plus part-time support in Product, DevOps, and Compliance + access to a senior Railsware Director with experience shipping many products.

Yaroslav Lazor — engineering & product (previously worked on Calendly)

Umar Ashraf — markets & distribution (runs a 4M+ YouTube trading channel, founder of Tradezella)

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 — flexible. We collaborate when needed and work independently when it’s more effective. We focus on results.
• 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

• Rust (we use Rust/Axum), 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

What you’ll work on (first 90 days)

• Building real-time market data pipelines (Level 2 data, order book reconstruction)
• Developing order flow visualizations (footprints, heatmaps, DOM, profiles, CVD)
• Improving the trading interface (charts, DOM, tape, order panel working together)
• Preparing live data features for partnerships with prop firms
• Integrating with market data providers
