Job Description Summary
For over forty years, HarbourVest has been home to a committed team of professionals with an entrepreneurial spirit and a desire to deliver impactful solutions to our clients and investing partners. As our global firm grows, we continue to add individuals who seek a collaborative, open-door culture that values diversity and innovative thinking.
In our collegial environment that's marked by low turnover and high energy, you'll be inspired to grow and thrive. Here, you will be encouraged to build on your strengths and acquire new skills and experiences.
We are committed to fostering an environment of inclusion that promotes mutual respect among all employees. Understanding and valuing these differences optimizes the potential of both the individual and the firm.
HarbourVest is an equal opportunity employer.
This position will be a hybrid work arrangement. You will receive 18 remote workdays per quarter to use at your discretion, subject to manager approval. For example, you may choose to work in the office 4 days per week and take one remote day weekly (typically 13 weeks per quarter), leaving 5 additional remote days to be used as needed.
Seated within our Quantitative Investment Science group, the Associate, Quantitative Developer turns machine learning, applied AI, and agentic workflow capabilities into reliable investment workflow software. This is a software engineering role first: you will write production Python, work deeply with data, build model pipelines and evaluation frameworks, and integrate AI-driven capabilities into the tools investment teams use every day. The role is ideal for a practical machine learning engineer who wants to build trusted, auditable systems for high-value quantitative and private markets workflows.
The ideal candidate is someone who has:
Strong software engineering fundamentals and a production-oriented machine learning mindset
A practical interest in using ML and agentic AI to improve investment research, data quality, decision support, and workflow scale
Healthy skepticism about model outputs, with strong instincts for evaluation, backtesting, monitoring, and human review
Comfort turning ambiguous analytical workflows into measurable, maintainable production systems
Strong collaboration skills across quant developers, data engineering, product, and investment stakeholders
Curiosity about finance, private markets, and the data problems behind investment decision-making
