📋 Description

• Lead the design, development, testing, and deployment of high-performance, fault-tolerant backend services supporting the FMX trading platform. • Own services and features end-to-end: spec writing → implementation → instrumentation → deployment → monitoring → iteration based on metrics. • Work within and help modernise a Java codebase while contributing to new service development in Go, Java and Kotlin. • Contribute to the architecture for order processing, market data distribution, and trade lifecycle management on a regulated product. • Build and maintain reliable daily reporting pipelines, ensuring data integrity and full audit trails across all trading activity. • Participate in 24/7 on-call rotations; contribute to SLO definition, alerting strategy, and incident response for mission-critical trading infrastructure. • Model and manage data for contracts, orders, positions, and settlements with an emphasis on correctness, integrity, and regulatory auditability. • Collaborate with the DevOps/Platform team to ensure services are observable, scalable, and compliant with MNPI and insider trading restrictions. • Conduct thorough code reviews, raising the bar on code quality, readability, security, and maintainability. • Leverage AI tools to accelerate development velocity while maintaining high standards for security, correctness, and regulatory compliance. • Establish and document team standards for AI usage (prompt patterns, code review checklists, validation strategies). • Contribute to a fast-paced 0→1 environment, unblocking others and taking initiative where processes are still being defined.

🎯 Requirements

• 4+ years of experience building highly scalable, high-performance backend applications or distributed systems. • Background in regulated exchange or financial infrastructure strongly preferred – brokerage, futures/derivatives exchanges (CBOE, CME, ICE), or similar CFTC/SEC-regulated environments. • Production experience with Java; Go experience or a strong demonstrated desire to work in Go. • Experience with event-driven architectures (Kafka, Kinesis, PubSub, or similar) in a financial or high-throughput context. • Strong understanding of data integrity and transaction management in PostgreSQL or equivalent RDBMS, including financial-grade data modelling. • Solid grasp of software design principles (SOLID, DRY) and testing methodologies (unit, integration, end-to-end). • Familiarity with CFTC compliance requirements, MNPI handling, and audit trail obligations in a regulated trading environment. • Experience with CI/CD pipelines, automated testing, and safe deployment practices for backend services. • Production reliability experience: monitoring, logging, alerting, on-call, and SLO definition. • Demonstrated experience using AI tools (Claude Code, Cursor, Copilot, etc.) to ship production code; able to articulate specific workflow improvements. • Communicates complex technical concepts clearly to engineering, compliance, and business stakeholders. • Thrives in a fast-paced, high-growth environment where priorities evolve and decisions are made quickly.
