Requires extensive experience in algorithmic or high-frequency trading, market data processing, FIX, trading infrastructure, Linux, networking, and performance optimization.

Designs, develops, tests, deploys, operates, and improves secure software solutions. Owns moderately complex features from refinement through production, applying modern engineering, cloud-native, CI/CD, testing, observability, DevSecOps, and production-support practices. Collaborates with product, architecture, security, data, operations, and business teams; diagnoses defects, evaluates technical trade-offs, supports less-experienced engineers, and applies AI-enabled tools responsibly.

Develop and maintain Java microservices and event-driven backend applications using Spring Boot and AWS. Build integrations through REST APIs, messaging, EDI, and databases; write tests; support CI/CD and containerized deployments; monitor production systems; and contribute to code reviews, architecture, requirements, troubleshooting, and application security. Collaborate with DevOps, architecture, and front-end teams throughout the software development lifecycle.

Leads software and DevOps engineers while developing shared engineering capabilities, reusable libraries, and technical standards. Provides hands-on leadership across .NET and React ecosystems, software design, coding, testing, automation, security, and delivery practices. Establishes governance for shared components and responsible AI-assisted development, partners with architecture, security, product, and delivery leaders, and drives adoption, metrics, continuous improvement, and career development across geographically dispersed teams.

Designs, implements, tests, reviews, and maintains PracticeMatch software products. The engineer contributes to system design, performance, security, compliance, documentation, and automated quality processes; troubleshoots production web applications; collaborates across engineering and business teams; and uses agentic AI tools such as Claude Code and Codex to support development, testing, deployment, and operations while reviewing generated work for quality and security.
