Staff Software Engineer - Margin & Risk

Accountabilities:

• • Own the architecture and technical roadmap for margin and risk capabilities across asset classes, including portfolio and intraday margin, options risk, real-time exposure limits, margin-call automation, and models for new products.

  • Design and build highly reliable services that translate complex margin methodologies, financial rules, and regulatory requirements into correct, testable, and observable systems.

  • Lead real-time risk enforcement on the order path, carefully balancing latency, accuracy, system resilience, and customer safety.

  • Drive reliability and performance across mission-critical services, including throughput, state recovery, database efficiency, failure isolation, and system availability.

  • Partner with Product, Brokerage Operations, Compliance, and adjacent engineering teams such as order management, ledger, account, and market data to establish clear system behavior and integration boundaries.

  • Establish engineering standards for transactional integrity, idempotency, reconciliation, testing, feature flags, staged rollouts, and other safeguards required for high-consequence financial systems.

  • Lead architecture and design reviews, mentor senior and mid-level engineers, and help strengthen technical ownership as the team scales.

  • Serve as a senior technical escalation point for production margin and risk incidents, driving root-cause analysis and durable improvements following failures.

  • Contribute directly to critical systems through design, implementation, troubleshooting, and performance optimization.

  Requirements:

  • 8+ years of backend or distributed-systems engineering experience, with demonstrated technical scope and ownership; experience owning a consequential production system for two or more years is strongly preferred.

  • Proven experience owning or building high-volume systems where defects can result in financial loss, data-integrity issues, or inappropriate customer restrictions.

  • Strong experience designing and shipping transactional, low-latency, high-throughput systems.

  • Advanced proficiency in Go, or deep expertise in Java, C++, or Rust combined with a willingness to work primarily in Go.

  • Deep understanding of relational databases, particularly PostgreSQL, including transactions, consistency, concurrency, and data integrity.

  • Experience with event-driven and service-oriented architectures, including technologies such as gRPC, Kafka, RabbitMQ, or comparable messaging and RPC systems.

  • Experience working with Kubernetes and production-grade distributed infrastructure.

  • Strong focus on correctness, including testing strategies, edge-case analysis, reconciliation, safe deployments, and controlled production rollouts.

  • Excellent communication skills, with the ability to explain complex technical and financial concepts to engineering, operations, compliance, and business stakeholders.

  • Demonstrated technical leadership and mentoring experience, with the ability to influence architecture and engineering practices without direct managerial authority.

  • Hands-on experience with margin or risk systems across multiple asset classes is highly valuable.

  • Familiarity with margin methodologies such as Reg T, portfolio margin, options spread margin, or futures margin is a plus.

  • Experience with brokerage, clearing, exchange, ledger, payments, or settlement systems is beneficial.

  • Knowledge of options, derivatives, multi-leg strategies, and associated risk characteristics is advantageous.

  • Experience with workflow orchestration technologies such as Temporal for long-running financial processes is a plus.

  • Experience with observability, production performance tuning, migrations, or refactoring of production-critical systems is valuable.

  Benefits:

  • Competitive salary and stock options.

  • Health benefits.

  • Remote work within the applicable Americas/US setup.

  • One-time USD $500 new-hire home-office setup allowance.

  • USD $150 monthly stipend provided through a Brex Card.

  • Opportunity to work on high-consequence financial infrastructure spanning multiple asset classes.

  • Staff-level technical ownership and influence without direct people-management responsibilities.

  • Collaboration with engineering, product, operations, compliance, and financial-market specialists in a globally distributed environment.
