This role will lead the evolution of our architecture, modernizing and consolidating ledger, fund movement, and reconciliation logic into a coherent, cloud-native foundation. You will also drive the thoughtful use of AI-assisted development and operational tooling to increase engineering leverage, improve review quality, and accelerate modernization without compromising financial correctness or regulatory integrity. These are mission-critical systems where every state transition must be financially correct, auditable, and resilient under failure—because design flaws directly impact customer funds, regulatory standing, and firm capital. As a Staff Engineer, your work will have a profound impact on our core FCM infrastructure, directly influencing our business’s bottom line. You will set the technical standard for the FCM engineering organization: defining architecture patterns, establishing engineering best practices, mentoring and elevating the engineers around you, and making high-stakes design decisions that determine whether our platform scales to meet the demands of a rapidly growing, globally distributed customer base. You will partner closely with engineering leadership, product management, compliance, and brokerage operations to ensure that every system you design is auditable, resilient, and built to serve both customers and regulators. In this role you will: Define and own the foundational architecture of NinjaTrader’s 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, meaningful code reviews, pairing on complex problems, and leading architecture and design sessions that elevate the engineering bar Establish and enforce best practices across the FCM platform, including API design standards, testing strategies (unit, integration, contract, chaos), 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 while preserving strict financial and audit constraints Design compliance-critical systems where regulatory requirements are treated as first-class architectural constraints, embedding audit trails, segregation controls, and compliance checkpoints directly into platform design Partner with engineering leadership, including the CTO and Director of Engineering, to shape broader 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 What you'll need: 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 architect
