## About the Role

* 8 + years of software engineering experience building and shipping production systems at scale.
 * Deep proficiency in C# and the .NET ecosystem, with a track record of designing production services used across multiple teams.
 * Experience with React, TypeScript, or other modern frontend frameworks.
 * Experience designing service boundaries and API versioning in a microservices or modular architecture.
 * Extensive experience building distributed, high-availability systems, including asynchronous, event-driven communication between services (e.g., message queues, pub/sub, or streaming).
 * Deep database experience with PostgreSQL or SQL Server, including schema design, query optimization, and transactional behavior.
 * Experience with observability tools and distributed tracing in production environments.
 * Proven track record of owning production systems, including debugging and incident response.
 * Experience with container technologies (Docker) and cloud platforms (AWS)
 * Strong testing mindset with practical experience across unit, integration, and system testing.
 * Proven capability leveraging AI developer tooling effectively while upholding rigorous standards for code health and maintainability.
 * Excellent problem-solving skills, with the ability to debug complex issues across multiple systems.
 * Demonstrated ability to build consensus and drive complex technical initiatives across teams without relying on direct authority.
 * Excellent communication skills, including the ability to explain technical trade-offs to both engineering and product stakeholders.

Preferred

 * Kubernetes experience (EKS or equivalent), Helm, or GitOps (ArgoCD) tooling.
 * Experience with real-time client comms (SignalR/WebSockets).
 * Background in high-throughput, low-latency systems, including performance tuning across multiple services.
 * Incident leadership (RCA, remediation follow-ups).
 * Previous work in financial services, fintech, or other compliance-regulated environments.
 * Understanding of trading systems, market data, or brokerage operations.

## Description

* Design and build services and APIs that power core trading platform capabilities.
 * Own initiatives end-to-end, from technical design through production deployment, monitoring, and iteration.
 * Collaborate with product and design to translate user needs into scalable, maintainable technical solutions.
 * Contribute to system architecture decisions, establishing patterns and practices that other teams can follow.
 * Write clean, well-tested code with strong focus on reliability, performance, and operational excellence.
 * Participate in on-call rotations, respond to incidents, and drive continuous improvement of system reliability.
 * Build and maintain observability into your systems through metrics, logging, and distributed tracing.
 * Occasionally work across the stack, contributing to the React/TypeScript frontend as features require.
 * Mentor engineers through code reviews, pairing sessions, and sharing knowledge about system design and best practices.
 * Balance technical debt against feature delivery, making thoughtful trade-offs based on business priorities and technical constraints.
 * Strengthen engineering culture through documentation, tooling improvements, and process refinements.
