Про проєкт
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 — 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.
