Investment Systems Application Engineer III

Core Responsibilities

Test Engineering & Automation Frameworks

• Design and build automated testing frameworks for backend services data pipelines and endtoend 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 controlsbydesign 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 taxloss harvesting and analytics pipelines

Auxiliary Development (Backend / Data / FullStack 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 cloudnative 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 postrelease 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 endtoend)
• Solid understanding of investment domain concepts (portfolios positions transactions tax lots trading lifecycle or analytics workflows)
• Experience working with dataintensive 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 eventdriven 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 multiplierraising engineering standards across the VPI platform
