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
