Backend Developer

Responsibilities:

• Own the architecture of the Client Trading Engine, Pricing Engine, Risk Management Engine, and Smart Hedging.
• Break complex, ambiguous systems into smaller components with clear contracts, clear scope, and independent deliverability.
• Set and drive the architectural vision for trading and hedging, and take large architectural bets through to completion.
• Build for scale design systems that hold up as volume, venues, and currency corridors grow.
• Own the observability standard across all components, so the behavior of the trade and risk path is legible when it matters.
• Design meaningful alerting, fallback, and recovery strategies across systems.
• Coach and mentor engineers on the team, and raise the technical bar through design reviews and feedback.
• Partner with product, risk, and the two pod EMs to connect architectural decisions to TPV, gross revenue, and net revenue outcomes.

Requirements:

• 7-12 years of experience building and operating production backend systems.
• Deep experience with distributed systems consistency, failure modes, and the trade-offs between them.
• Experience building orchestrators and complex, long-running workflows that must be durable and recoverable.
• Strong command of databases at scale, sharding, multi-region deployments, and the data protection constraints that shape them.
• Track record on high-scale systems, including the observability and operational tooling that keeps them healthy.
• Comfort with abstract, ambiguous problems: you're the person who turns a vague mandate into scoped, sequenced deliverables.
• Hands-on. You still write code, and your architectural judgment comes from building.
• Heavy AI user. You use AI coding tools with real technique and get materially more done because of it.
• Influential and collaborative. You set direction by inspiring and persuading people, not by relying on authority.
• Data-driven, and you operate with high agency; you find the important problem and go solve it.
