Your Role:

We are seeking a Staff Engineer to join our Risk and Margin Team. This is a high-impact technical role for someone who wants to remain deeply hands-on while shaping the architecture of our trading infrastructure. You will be the technical authority on low-latency systems, responsible for pushing the boundaries of performance, determinism, and scale across order routing, execution, and market connectivity.

You will not manage people directly — instead, you will lead through technical expertise, code quality, and design influence, mentoring others while continuing to be a principal contributor to mission-critical systems.

Key Responsibilities

• Own the architecture, design, and technical roadmap of the risk and margin platform.

• Lead initiatives on low-latency optimizations, deterministic performance, and resiliency.

• Guide integration with exchanges and liquidity venues (FIX, OUCH, ITCH, proprietary APIs) at scale.

• Establish best practices for high-frequency trading system development (testing, monitoring, incident response).

• Partner with risk and compliance teams to embed real-time pre-trade risk, credit, and margin controls.

• Act as a multiplier: mentor engineers, perform design reviews, and elevate engineering standards.

• Lead architecture discussions and long-term system design for scalability and resilience.

• Drive cross-team projects that impact multiple trading desks (e.g., global order routing, fault-tolerant market data infra).

• Proactively identify scalability bottlenecks and lead refactoring/redesign initiatives.

• Serve as a technical point of escalation for production trading issues.

Qualifications

• Bachelor’s or Master’s in Computer Science, Engineering, or equivalent.

• 10+ years of software engineering experience, with significant time in trading, fintech, or distributed systems.

• Deep expertise in Go, C++, or Java, with a track record of building low-latency, high-throughput systems.

• Strong foundation in operating systems internals, networking, and concurrency.

• Demonstrated experience with architecture & system design for trading systems.

• Strong knowledge of messaging, storage, and distributed computation frameworks (Kafka, RabbitMQ, Redis, Postgres, Aerospike).

• Experience leading large-scale migrations/refactors in production-critical environments.

• Proven track record of mentorship and technical leadership across multiple teams.

Preferred Skills

• Experience with equities, derivatives, or FX trading systems.

• Knowledge of cloud, containerization, and orchestration tools (Kubernetes, Docker).

• Experience with observability stacks (Prometheus, Grafana, ELK).

• Contributions to open-source projects in systems programming or infrastructure.

• Experience scaling engineering orgs and setting technical strategy.

How We Take Care of You:

• Competitive Salary & Stock Options

• Health Benefits

• New Hire Home-Office Setup: One-time USD $500

• Monthly Stipend: USD $150 per month via a Brex Card
