This is a rare opportunity to shape the architecture and implementation of a federally regulated financial system from the ground up. You'll be responsible for designing and developing core backend services for a compliant, low-latency trading platform, working closely with architects, compliance leads, and frontend engineers.


You must be a strong developer first, capable of owning complex services end-to-end, while also mentoring team members and influencing architectural decisions. This is not a management role it is a hands-on, high-impact engineering position for someone passionate about building real-time, resilient, and secure systems.

Key Responsibilities
• Design, develop, and deploy backend services that support:


o A performant Order Management System (OMS) for trade matching and execution.


o Clearing House integration for trade settlement and funds movement.


o Regulatory compliance modules for pre-trade/post-trade checks and reporting (CFTC, NFA).


o Back office reporting and reconciliation tools for statements, balances, and DCO communication.
• Write high-quality, production-grade code using .NET Core and C++, with an emphasis on performance, correctness, and maintainability.
• Define and build scalable APIs, ensuring seamless integration with frontend systems (SwiftUI, Jetpack Compose, Next.js).
• Own technical decisions across services, including data modeling, service boundaries, observability, and error handling.
• Deploy, monitor, and support backend systems in a cloud-native AWS environment (DynamoDB, Kafka, EC2, EKS).
• Collaborate closely with product managers, architects, compliance teams, and fellow engineers to iterate on requirements and deliver production-ready solutions.
• Guide and mentor junior engineers through code reviews and technical support, while staying hands-on with daily development tasks.
• Identify opportunities to integrate third-party services or open-source components to accelerate delivery.


Tech Stack & Tools
• Languages: .NET Core (C#), C++
• Architecture: Microservices, event-driven systems
• Cloud: AWS (EC2, EKS, DynamoDB, Kafka, CloudWatch)
• Data: Real-time messaging, secure audit logs, low-latency data models
• DevOps: CI/CD pipelines, observability tools, Infrastructure-as-Code (IaC)

Required Qualifications
• 8+ years of backend development experience in high-throughput, low-latency environments.
• Proven, hands-on experience building trading systems, exchange platforms, or other regulated financial applications.
• Strong programming skills in .NET Core and C++, with the ability to design for performance, safety, and concurrency.
• Experience with AWS cloud infrastructure and deploying services in production environments.
• Deep understanding of financial trade lifecycles, including order routing, clearing, and post-trade reporting.
• Demonstrated ability to build and expose APIs via an API Gateway, working in close sync with frontend teams.
• Familiarity with CFTC, NFA, or other financial compliance frameworks.
• Excellent debugging, problem-solving, and communication skills.


Preferred Qualifications
• Prior experience with sports betting, binary markets, or prediction market platforms.
• Exposure to federally regulated financial systems, as opposed to state-level gaming regulation.
• Experience integrating third-party systems such as FIS or clearing house APIs.
• Practical knowledge across Front, Mid, and Back Office systems in trading environments.


What You'll Bring
• You re a builder who thrives on writing code and solving complex technical problems.
• You ve shipped production systems in regulated financial environments.
• You care about performance, testability, and long-term maintainability.
• You value clarity, autonomy, and high ownership in engineering work.
