Job description

Archer is collaborating with Vanguard to connect them with exceptional professionals for this role.

This Role

Designs, develops, and operates production quantitative investment systems.

• Designs, engineers, tests, deploys, and supports software systems that directly influence investment decisions, portfolio construction, trading, risk management, and research workflows. Translates quantitative research into scalable, production-grade investment capabilities while maintaining the highest standards of reliability, reproducibility, and operational rigor.
• Engineers research-to-production model delivery pipelines.
• Builds and maintains the architecture required to move quantitative models, datasets, and analytical processes from research through validation, testing, sandbox environments, and ultimately production deployment using modern software engineering, CI/CD, MLOps, and governance practices.
• Develops advanced machine learning and AI-enabled investment capabilities.
• Designs and implements machine learning, statistical learning, optimization, and AI-based solutions to improve security selection, alpha research, portfolio construction, model monitoring, and investment decision support. Contributes throughout the model lifecycle including feature engineering, training, validation, deployment, observability, and ongoing performance evaluation.
• Designs and implements GenAI, retrieval, and knowledge systems.
• Designs enterprise-grade GenAI solutions including Retrieval Augmented Generation (RAG), semantic search, knowledge retrieval, embedding architectures, reranking systems, agentic workflows, context engineering strategies, evaluation frameworks, and LLM orchestration patterns to enhance quantitative research productivity and insight generation.
• Establishes software engineering and quantitative development standards.
• Develops reusable frameworks, libraries, services, and platform capabilities while establishing engineering standards for testing, validation, code review, performance optimization, reproducibility, data lineage, and operational excellence within quantitative investment environments.
• Advances quantitative investing through emerging technology.
• Evaluates and applies new technologies including machine learning, deep learning, agentic AI systems, LLMs, knowledge graphs, cloud-native architectures, distributed computing, model observability tools, and software engineering best practices to improve investment outcomes and research efficiency.
