[Remote] Full Stack Quantitative Developer

Note: The job is a remote job and is open to candidates in USA. Trinity Technology Solutions LLC is hiring a Full Stack Quantitative Developer to support credit, private credit, structured products, and CLO businesses. The role involves building end-to-end applications, quantitative models, data integrations, reporting tools, and modern cloud-aware architectures while partnering with portfolio management, risk, operations, investor relations, and client solutions teams.

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 firmwide 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

Skills

• • 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
• • Languages: strong proficiency in at least one of Python, C#/.NET, or TypeScript/JavaScript, and working competence in a second
• • Backend: REST APIs, asynchronous services, and microservice patterns. Python or NET/C# experience strongly preferred given existing systems
• • Frontend: modern JavaScript frameworks (React/Angular), responsive web design, HTML5/CSS, and cross-platform optimization for mobile
• • Data: expert SQL (window functions, query tuning, set-based thinking); experience with NoSQL/document stores
• • Quant / numerical: comfortable with NumPy/pandas (or equivalent), basic statistics, fixed-income math (duration, convexity, OAS), and cash flow modeling
• • Tooling: Git (or TFS), CI/CD, DevOps, Confluence, unit and integration testing frameworks
• • 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
• • Cloud: experience deploying and operating services on Azure or AWS is a plus
• • Reporting / BI: Tableau dashboard development or SSRS a plus
