Financial Software Engineer

About Our Client Our client is redefining the infrastructure behind one of the largest and most complex markets in the world: OTC derivatives. This market moves trillions of dollars daily, yet much of the underlying technology has remained largely unchanged for decades. Our client is building a modern, AI-native platform designed to power the next evolution of financial services—combining deep financial engineering with a modern cloud stack and world-class developer experience. The founding team comes from tier-one banks, hedge funds, and trading firms, where they previously built and operated some of the most sophisticated systems in the industry. Today, they are applying that expertise to create infrastructure capable of processing the most complex transactions across global financial markets—at scale, with precision, and with a focus on long-term impact. Their clients include some of the most sophisticated banks, hedge funds, and asset managers in the world. The problems are technically challenging, the data is dense, and the systems being built will influence how this market operates for decades. Technology Environment This is a modern, cloud-native engineering organization:

• Serverless, cloud-native architecture by design
• Infrastructure as Code (IaC)
• Backend services written primarily in Python and Java
• Frontend built with TypeScript and React
• Heavy use of modern AI tooling and foundation models
• Fully automated SDLC with rapid, intraday deployments
• Strong emphasis on reliability, observability, and developer velocity

About the Role

As a Financial Engineer, you will play a hands-on role in building and scaling analytics and models for OTC derivatives across asset classes. You’ll focus on translating complex financial instruments into robust, production-grade systems—owning everything from pricing logic to trade lifecycle workflows. This role sits at the intersection of financial engineering, software engineering, and modern AI-enabled infrastructure. You’ll collaborate closely with platform engineers, AI engineers, and domain experts to integrate models into a broader capital markets platform used by institutional clients. This role is onsite in New York City. What You’ll Be Working On

• Modeling OTC derivatives from vanilla to exotic products across asset classes
• Implementing trade lifecycle logic, including:
• Cash flow calculations
• Position management
• Trade state transitions
• Designing and validating pricing and analytics workflows
• Integrating financial models into scalable backend services
• Collaborating cross-functionally with engineering, product, and domain specialists
• Ensuring accuracy, transparency, and robustness in financial calculations

Required Qualifications

• Bachelor’s degree in Financial Engineering, Computer Science, Mathematics, Physics, or a related field
• Practical experience with:
• Quantitative modeling
• Statistics and linear algebra
• Financial data analysis
• Strong understanding of derivatives and financial engineering concepts
• Proficiency in Python
• Strong problem-solving and communication skills
• Ability to work effectively with cross-functional engineering teams
• Willingness to work onsite in NYC

Bonus Qualifications (Nice to Have)

• Deep expertise in OTC derivative pricing and modeling across multiple asset classes
• Familiarity with ISDA concepts and data models (e.g., CDM, FpML)
• Strong understanding of:
• Trade lifecycle management
• Position and exposure management
• Experience implementing or validating pricing models in production
• Knowledge of collateral management, margining, and settlement processes
• Experience with electronic trading and protocols (e.g., FIX, clearing workflows)
• Exposure to Generative AI applications in finance (e.g., OpenAI, Anthropic, Gemini)

Why This Role Stands Out

• Work on foundational infrastructure, not surface-level features
• Solve genuinely hard problems at the intersection of finance and technology
• Join a team with deep domain credibility and long-term vision
• Build systems that will shape how institutional markets operate in the future
