Staff Software Engineer, FCM

You will serve as the technical domain owner for the Transaction Ledger & Treasury system within the FCM platform, taking accountability for the financial correctness, reconciliation integrity, and system-of-record architecture of the brokerage systems. You'll lead the evolution of the architecture, modernizing and consolidating ledger, fund movement, and reconciliation logic into a cohesive cloud-native foundation. You'll drive thoughtful use of AI-assisted development and operational tooling to increase engineering leverage and review quality without compromising financial correctness or regulatory integrity. You will set the technical standard for the FCM engineering organization, defining architecture patterns, establishing best practices, mentoring engineers, and making high-stakes design decisions that determine whether the platform scales to a rapidly growing, globally distributed customer base. You'll partner closely with engineering leadership, product management, compliance, and brokerage operations to ensure every system you design is auditable, resilient, and built to serve customers and regulators alike.

Responsibilities

• Define and own the foundational architecture of the cloud-native FCM platform on GCP/Kubernetes, including concurrency models, data consistency guarantees, service boundaries, and integration contracts across clearing, risk, and reporting systems
• Architect systems that process high-throughput trade flows with deterministic behavior under concurrency, partial failure, and asynchronous clearing acknowledgments across a 24/7 trading window
• Serve as the technical north star for the FCM engineering team by conducting deep code reviews, pairing on complex problems, and leading architecture and design sessions
• Establish and enforce best practices across the FCM platform, including API design standards, testing strategies, observability and SLI/SLO frameworks, CI/CD standards, and infrastructure-as-code patterns
• Define what excellence looks like for regulated financial systems and hold the team accountable to those standards
• Champion the responsible use of AI-assisted coding, testing, and code review workflows to increase velocity and reduce defects
• Design compliance-critical systems embedding audit trails, segregation controls, and compliance checkpoints directly into platform design
• Partner with engineering leadership to shape technical strategy and govern system-of-record architecture, ledger data models, fund movement APIs, reconciliation workflows, and cross-service balance interactions
• Represent the FCM platform in cross-functional architecture forums and drive alignment across teams
• Take ownership of the most complex and high-impact technical challenges, transforming ambiguous problems into well-defined, executable plans

Requirements

• 8–12+ years of progressive software engineering experience, with demonstrated impact at the Staff level or equivalent scope of influence
• Deep expertise designing, building, and operating large-scale distributed systems in cloud environments (GCP strongly preferred; AWS or Azure acceptable)
• Hands-on experience with Kubernetes, event-driven architectures, and infrastructure-as-code tools such as Terraform
• Strong proficiency in modern backend languages such as Python, C++, Go, or similar
• Experience leveraging AI-assisted development tools, including code generation, static analysis, and automated test synthesis
• Experience in financial services, capital markets, or brokerage technology, including trade lifecycle systems, clearing and settlement
• Proven track record as a technical authority and mentor who has raised the engineering bar of their teams
• Experience designing distributed systems where financial correctness, reconciliation, segregation of funds, and audit integrity are non-negotiable architectural constraints
• Excellent communication skills with the ability to articulate complex technical concepts to engineers and non-technical stakeholders
• Demonstrated ownership of initiatives end-to-end, from problem framing and design through implementation, deployment, and operational maturity
