Senior Software Engineer (Trading-Related Project)

• Small founding team: 2 co-founders + 1 engineer (we’re hiring you as the 2nd) + part-time consultants on Product, DevOps, and Compliance + access to a senior Railsware Director who has shipped many products. We work spec-driven - planning before prompting, planning before coding.

Co-founders:

• Engineering & Product Lead - Senior technologist with a proven track record of building and scaling widely adopted SaaS products, including prior involvement in the development of a globally recognized scheduling platform.
• Markets & Distribution Lead - Experienced growth and distribution specialist with a substantial digital audience (multi-million subscriber base), and founder of a product operating in the trading and analytics space, demonstrating established market reach and user acquisition capabilities.

What we’re building

• TradeTerm is the audit-first replay platform that prop firms, Tradezella users, and serious futures traders have been missing. Bookmap-class orderflow UX, with audit + replay + execution as the wedge. Distribution is locked from day 1: Umar’s 4M-sub launch channel + warm Tradezella audience - not “build for a year then maybe.”

What you’ll get

• Real ownership. Spec * plan * build * ship. No ticket queue.
• Skin in the game. Trade on the platform you build. Eat your own cooking.
• AI-first, true team. You’ll work with people who use AI as a research / planning / execution stack - not as a copilot. The kind of disciplined workflow most engineers spend years figuring out alone.
• Market comp + broad geo. Cash comp at market rate. Hiring globally.
• Fluid working style. We pair when it accelerates the work. We go async / deep when the work needs it. No ceremony - output > activity., * A senior full-stack engineer who is also an active trader.

Do you have experience in WebSocket?, * Required: 5+ years senior engineering - comfortable across low-latency backend and modern frontend (React 18+/TypeScript)

• Active trading experience - futures or crypto, day or scalp. You’ve read the tape. You traded lots of terminals and know what’s beautiful.
• Spec-driven, AI-orchestrated development. You plan deeply, orchestrate agents.
• Real-time market data - WebSocket streaming, order books, Level 2 depth
• You produce your own product specs; UX decisions per the UX guide / UX advisor
• Fluent written English
• Nice to haves: Rust (our backend is Rust/Axum), or Go / C++
• WebAssembly / native-quality browser rendering (Emscripten, dear imgui, egui) - ability to build cryexc / Bookmap-class browser tools
• MBO data, footprint charts, DOM/ladder, orderbook + liquidation heatmaps, market profile, volume profile, CVD
