Aufgaben

• Build full‑stack applications across credit platforms including backend services, APIs, data pipelines, and modern web front ends.
• Develop quantitative models for fixed‑income valuation, cash flow projections, and risk analysis.
• Integrate third‑party systems (Geneva, market data, CRM, admin platforms) with clean adapters.
• Migrate legacy .NET/C# apps to modern TypeScript/React front ends and Python/.NET services in cloud environments.

Jobbeschreibung

Responsibilities

• Build full‑stack applications across our credit, private credit, and structured products platforms — backend services, APIs, data pipelines, and modern web front ends used by various business teams across the firm
• Develop quantitative models and analytics for fixed‑income and structured product valuation, cash flow projections, scenario analysis, and portfolio risk decomposition
• Integrate third‑party systems including Geneva (portfolio accounting), market data vendors, CRM platforms, and administrative platforms, design clean, well‑tested adapters and reconciliation logic
• Participate in the migration of legacy .NET/C# applications and SSRS reports to modern, scalable architectures (TypeScript/React front ends, Python or .NET services, cloud‑deployed) with responsive UX across desktop and mobile
• Own data quality end‑to‑end — ingestion, normalization, validation, and lineage — for firm‑wide positions, partnering with the data management team on governance and controls
• Build reporting and BI spanning Tableau dashboards, internal web tooling, investor reporting, and ad‑hoc requests for portfolio composition and DDQ responses
• Translate business needs into engineering — gather requirements directly from PMs, analysts, risk, IR, and operations; document functional and technical specs; write clear UAT plans and lead testing
• Ship like an engineer — write tests, use source control (GIT/TFS), open clean PRs, manage tickets in DevOps, deploy through CI/CD, and monitor what you ship in production
• Use AI coding assistants well — accelerate delivery, reduce boilerplate, and improve code quality, while applying the verification, security, and review standards described later in this document

Qualifications

• Bachelor's degree (or higher) from a top‑tier university in computer science, mathematics, physics, financial engineering, or another quantitative discipline
• 5+ years of professional software engineering experience, including production ownership of customer‑facing or business‑critical systems
• 2+ years working in capital markets, ideally at a hedge fund, asset manager, investment bank, or financial technology vendor — with direct exposure to fixed income, structured products, derivatives, private credit, or CLOs
• Demonstrated success delivering full‑stack applications end‑to‑end, from requirements through production deployment and support
• Strong proficiency in at least one of Python, C#/.NET, or TypeScript/JavaScript, and working competence in a second
• REST APIs, asynchronous services, and microservice patterns. Python or .NET/C# experience strongly preferred given existing systems
• Modern JavaScript frameworks (React/Angular), responsive web design, HTML5/CSS, and cross‑platform optimization for mobile
• Expert SQL (window functions, query tuning, set‑based thinking); experience with NoSQL/document stores
• Comfortable with NumPy/pandas (or equivalent), basic statistics, fixed‑income math (duration, convexity, OAS), and cash flow modeling
• Git (or TFS), CI/CD, DevOps, Confluence, unit and integration testing frameworks
• Experience deploying and operating services on Azure or AWS is a plus
• Tableau dashboard development or SSRS a plus
• Solid understanding of fixed‑income securities, bank loans, and credit instruments
• Familiarity with private credit deal lifecycle: sourcing, underwriting, closing, ongoing monitoring, amendments, and valuation
• Awareness of portfolio accounting concepts (Geneva exposure is a plus) and portfolio risk frameworks (Bloomberg Port, RiskMetrics or equivalent)
• Strong analytical and practical problem‑solving skills; you reason from first principles and verify assumptions
• Excellent written and verbal communication; able to explain technical work to PMs and senior executives
• Self‑starter with strong work ethic; comfortable juggling multiple workstreams under deadline pressure
• Detail‑oriented, with high standards for code quality, data accuracy, and operational discipline
• Team player who collaborates well across technical and non‑technical groups
