You will work on the TypeScript front-ends and the Go services that serve them. We are evolving our front-end applications into a modular, plugin-based platform that other engineers and teams build on-so you will build reusable UI modules, component libraries, and SDKs as much as end-user features, and also the Go services that ingest, process, and serve market and on-chain data to these applications. You will own your work from structured product requirements through to production. This is a highly collaborative role in a fast-paced environment where clean design, high performance, and responsive UIs are critical to the business. You don't need a background in trading or finance. We care most about engineering craft and will teach you the domain. Responsibilities * Collaborate with traders, researchers, and product managers to translate complex workflows into elegant UI solutions * Design and implement high-performance, responsive front-end applications using a current-generation TypeScript framework (Svelte, React, or Vue) * Design, build and operate Go back-end services with security and performance considerations baked into their design * Own service boundaries and data contracts end-to-end, from Go services to typed front-end SDKs * Build reusable UI modules, component libraries, and SDKs for a modular, plugin-based UI platform * Build real-time UIs that ingest and render high-frequency market and on-chain data from multiple streaming sources * Develop high-performance data visualizations for large, fast-updating datasets, using canvas-based charting (e.g. uPlot, TradingView Lightweight Charts) and D3.js for bespoke views * Integrate the front-end with back-end services through typed SDKs and MCP-based interfaces, including real-time market and on-chain data * Drive architecture and performance decisions for modular, extensible systems, with scalability and maintainability in mind * Deploy and maintain applications, keeping them reliable and performant under heavy load * Write and maintain automated tests and take part in code review to keep the codebase reliable and maintainable * Support system maintenance and feature evolution with a high delivery cadence and short iteration cycles * Mentor other engineers and promote engineering best practices across the team, * Phone Screening - A screening session with a few on-the-spot technical questions to assess your fundamental knowledge and problem-solving approach * Assignment - A take-home assignment to demonstrate your approach, critical thinking, and relevant skills * Assignment Review - A discussion of your assignment, focusing on your approach, reasoning, and solutions * CTO Interview - Interview with the CTO to discuss your experience, technical expertise, problem-solving approach, and overall fit for the role * Co-Founder Interview - A concluding discussion to evaluate cultural fit, strategic alignment, and how you resonate with the firm's values
