Investment Systems Application Engineer - III

About this role

Core Responsibilities Test Engineering & Automation Frameworks • Design and build automated testing frameworks for backend services, data pipelines, and end‑to‑end investment workflows • Develop regression testing, scenario validation, and deterministic validation suites for portfolio calculations, tax logic, and trading workflows • Create reusable testing tools, harnesses, and datasets (e.g., golden datasets, synthetic data generation) • Integrate automated testing into CI/CD pipelines to enable continuous validation

Controls & Validation (Investment Systems Focus) • Implement controls‑by‑design to ensure accuracy, consistency, and completeness of investment workflows • Build validation layers that detect data anomalies, workflow breaks, and calculation discrepancies • Ensure traceability and reproducibility of results to meet audit and regulatory expectations • Support development of validation frameworks for portfolio construction, tax‑loss harvesting, and analytics pipelines

Auxiliary Development (Backend / Data / Full‑Stack Support) • Contribute to backend services or data pipelines to enable testability, observability, and validation hooks • Develop supporting APIs, utilities, or UI components that aid in testing, debugging, and workflow validation • Improve system instrumentation to enable better monitoring and validation

Cloud & Engineering Practices (AWS) • Build and run validation frameworks on AWS using scalable, cloud‑native patterns • Integrate testing tools into CI/CD pipelines and deployment workflows • Contribute to observability (logging, metrics, tracing) to support validation and issue diagnosis

SDLC & Production Support • Participate in design, code, and test reviews to ensure quality is built in early • Support defect identification, triage, and root cause analysis • Contribute to production validation, reconciliation checks, and post‑release verification • Ensure solutions comply with information security and technology policies

Experience Required • 5+ years of experience in software engineering, test engineering, or platform engineering within investment, wealth management, or financial systems • Strong programming skills in Python (preferred) or Java • Experience building automated testing frameworks (unit, integration, and end‑to‑end) • Solid understanding of investment domain concepts (portfolios, positions, transactions, tax lots, trading lifecycle, or analytics workflows) • Experience working with data‑intensive systems and validating data quality and accuracy • Familiarity with CI/CD pipelines and cloud environments (AWS preferred)

Preferred • Experience implementing controls, validation frameworks, or reconciliation processes in financial systems • Exposure to model validation, analytics validation, or calculation verification workflows • Experience with distributed systems, microservices, and event‑driven architectures • Familiarity with observability tools and debugging complex production systems

What Success Looks Like • You build robust automated validation frameworks that significantly reduce production defects • You improve confidence in investment workflows by ensuring correctness and reproducibility • You embed testing and control mechanisms directly into system design and delivery pipelines • You act as a quality multiplier—raising engineering standards across the VPI platform
