We are seeking a hands-on Lead Backend Engineer to help build a new Futures Commodity Commissions Market (FCM) platform a greenfield, regulated financial trading product focused on binary sports prediction markets.

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:

• • A performant Order Management System (OMS) for trade matching and execution.
  • Clearing House integration for trade settlement and funds movement.
  • Regulatory compliance modules for pre-trade/post-trade checks and reporting (CFTC, NFA).
  • 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

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
