About the Opportunity

ZipStaff is seeking a Full-Stack Python Engineer for financial modeling, analytics, and research systems at a leading housing-finance organization.
You will build and support applications used to monitor market and credit risk. This is a hands-on Python and web seat — not a data-science research role and not a front-end-only role.

What You’ll Do:

  • Design, develop, and support systems in financial modeling, analytics, and research.
  • Write new code and review changes against standard engineering practices.
  • Support operational execution of software used to monitor and control market and credit risk.
  • Modify and maintain analytics applications.
  • Help financial research and engineering define application requirements.

Required Qualifications:

  • 5+ years developing analytics software applications, or a Master’s in Computer Science, Software Engineering, or a related field with 2+ years.
  • Bachelor’s or Master’s in Computer Science, Software Engineering, or a related technical field.
  • Practical Python, including web technologies (Flask, Dash) and data processing (Pandas, NumPy).
  • Web applications: HTML, CSS, JavaScript, and the ability to write production code (React is in the must-have line).
  • SQL and relational databases.
  • Linux / Unix.
  • Demonstrated knowledge of quantitative finance.
  • Ability to work on-site in McLean, VA.
  • Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:

  • AI experience, including LLMs used to build agentic applications.
  • JavaScript frameworks (jQuery, DataTables, React) and front-end design (CSS, Tailwind).
  • Cloud: Google Kubeflow or AWS.
  • Fixed income, accounting, or capital markets.
  • Mortgage or housing-finance (GSE) experience.
  • R, Java, C, C++, or SAS.

Benefits:

  • Health Insurance.
  • Dental Insurance.
  • Vision Insurance.
  • 401(k) + 401(k) matching.
  • Paid time off.
  • Referral Program.

About ZipStaff:

ZipStaff partners with leading organizations to connect skilled technology professionals with high-impact contract opportunities. We focus on quality matches, clear communication, and long-term success for candidates and clients.
To apply, submit your resume highlighting Python analytics applications you built (Flask or Dash, Pandas), a web front end you shipped, and any quantitative-finance or risk context. Script-only or notebook-only backgrounds will not be considered.
