Title: Principal Software Engineer
Role Overview
The Principal Software Engineer in NTAM Investments Technology is a senior technical leader with 10+ years' experience responsible for architecting and delivering scalable software and data platforms with a strong emphasis on Python-based services, data engineering, and production-grade AI/ML enablement. This role partners closely with engineers, product owners, architects, and business stakeholders in NTAM Investments to build secure, reliable, and high-performance systems, while setting engineering standards and mentoring other engineers.
The ideal candidate has deep hands-on expertise in Python (PySpark/FastAPI), React, strong SQL and data modeling capabilities, experience deploying on Microsoft Azure/Cloud, and demonstrated ability to operationalize AI-driven applications by integrating machine learning models into production systems.
Key Responsibilities:
Technical Leadership & Architecture
- Understanding of Asset Management Investments asset classes (equities, fixed income, alternatives), portfolio theory, and investment constraints.
- Technical ownership, clearly communicate trade-offs, risks, and dependencies to senior investment and technology stakeholders.
- Lead the design, development, and deployment of scalable solutions using Python, Azure services, and SQL-based data platforms
- Define and enforce coding standards, architecture best practices, and development workflows through design and code reviews

- Design and optimize SQL data models, queries, and stored procedures in Snowflake for performance and scalability
- Establish strong testing and quality standards, including unit testing and API test automation

- Establish and maintain Copilot instruction files and reusable agent skills to encode team conventions (architecture guardrails, naming/testing standards, security expectations), reducing repetitive prompting and improving consistency of generated output across repositories.
- Define and scale an agentic SDLC approach where AI agents assist across the lifecycle (requirements/backlog drafting support, code scaffolding, test automation, documentation), with engineers retaining accountability for design decisions and quality gates.
- Partner with DevOps / platform teams to drive measurable outcomes from AI-assisted delivery (e.g., cycle time improvements, testing automation adoption) and proactively manage bottlenecks created by increased PR throughput and review load.
- Promote responsible and secure AI usage patterns, including guidance around prompt hygiene, data minimization, and avoiding unsafe behaviors (e.g., prompt injection risks, unsafe code generation) when using agents and AI assistants.
- Partner cross-functionally with engineering, QA, DevOps, and product teams to deliver cohesive solutions.
- Mentor and coach engineers across levels, raising the overall technical bar
- Communicate complex technical concepts clearly to non-technical stakeholders and influence architectural decisions.
- Experience with solutioning and integrating with Axioma portfolio optimizer , Risk models and developing Optimization constraints for Fixed Income portfolio construction.
- Experience with Aladdin Enterprise/Charles River (CRD), Bloomberg AIM or other Portfolio and Order Management, integrating Aladdin SaaS to develop Investment tools and processes.
