Remote Defi Developer Jobs in Ashburn, VA (NOW HIRING)

AI & Financial Engineering Developer

Location: McLean, Remote

Call notes:

This is a remote opportunity.
We use a variety of quantitative models to forecast mortgage defaults and prepayments in order to assess financial risk.
The goal is to leverage AI to assist users throughout the model execution lifecycle, including formatting inputs, interpreting data elements, and providing guidance during model execution.
Since we have different models for different mortgage products, the AI should be able to understand the specific model being executed and provide contextual assistance accordingly.
The AI should be capable of analyzing the underlying model code and business logic to explain what is happening during execution, identify potential issues, and help diagnose model outputs.
This role requires a unique combination of AI expertise and Financial Engineering knowledge, as the individual will be working at the intersection of both domains.
Development will primarily be done in Python.
Candidates should have experience with quantitative financial models, including prepayment models, credit risk models, valuation models, and risk models.
Similar to industry-standard models (e.g., Opus), all models go through required security and governance checks before being deployed. They are then hosted securely within internal endpoints for enterprise use.
Job Description: AI & Financial Engineering Developer
Location: McLean, Remote
Must Have Qualifications: 7+ years of software development experience, including experience with API development, AI application development, and programming languages such as Python, C++, and Scala. Candidates should have 1-3 years of financial industry experience, with exposure to large language models (LLMs) and agentic AI development is a strong plus. A degree is preferred but not required. Prior experience with Fannie or Freddie is a strong plus.
