Senior Full Stack Developer, Trading & Data Systems

The Opportunity

We are seeking multiple Senior Developers reporting to our Head of Development to help design and build the next generation of our technology stack from the ground up. This is a full-scope role spanning everything we build — from our flagship trading platform and centralized data platform to UIs, APIs, market data architecture, integrations with third-party vendors, testing frameworks, deployment pipelines, and the business logic that powers it all. We’re looking for avid coders who are equally avid business problem solvers — engineers who get “lightly enraged” by inefficient systems and take it out on the keyboard by building better solutions. You will work closely with business, operations, and leadership to embed technology decisions into the firm’s strategy, with minimal bureaucracy and maximum ownership.

What You’ll D

• oHelp design and build Tradewinds 2.0, our flagship platform for deal funding, trade optimization, and order submission — from the ground up, across the full stack
• .Build Data Platform 1.0, our centralized platform for firm and market data, including Bloomberg integration, risk calculations, portfolio analytics, and data governance
• .Partner directly with business stakeholders to translate requirements into working software
• .Design and build APIs, backend services, and user interfaces across the full trade workflow — front-office order entry through back-office position management and reconciliation
• .Architect and maintain market data pipelines, ETL processes, and integrations with third-party vendor data feeds
• .Build and maintain testing frameworks, CI/CD pipelines, monitoring, and deployment tooling to keep business-critical applications running reliably — downtime matters
• .Own systems end-to-end — from requirements gathering and design through implementation, testing, deployment, and production support
• .Build business logic for trade workflows, position management, portfolio analytics, and risk — learning the underlying financial concepts deeply as you go
• .Evaluate and integrate third-party vendor systems where it makes sense; build custom where it doesn’t
• .Stay current on modern tooling and AI-assisted development, applying new techniques pragmatically where they accelerate the work
• .Identify inefficiencies in existing systems and processes — and build the solutions to fix them
• .Contribute to architecture decisions, code reviews, and the engineering standards of a rapidly growing platform
• .Help shape the technology direction of a growing financial firm — if it needs to be built, you’ll touch it
