Fidelity Investments • Boston, MA

12d • $126,000 - $255,000

About The Position

Fidelity’s Asset Management Technology organization is hiring a Director, Software Engineering – Machine Learning for its Graph Technology team within Data Science. This is a senior individual-contributor role, comparable to a Principal Engineer at many firms. The role is suited to a hands-on engineer who sets technical direction and leads through influence rather than people management.

The Director will serve as technical lead for production AI applications, including large language model systems, retrieval systems, and knowledge graphs used by quants and portfolio managers to support investment decisions. The position owns end-to-end architecture for multiple ML applications, establishes engineering standards, and includes ongoing coding. The engineer works directly with investment professionals to turn research questions into reliable, scalable tools.

The Graph Technology team is part of Quant Technology within Fidelity’s Asset Management Technology organization. It builds scalable investment tools, including knowledge graphs connecting companies, securities, and events and LLM-powered research tools that bring insights to portfolio managers. The team’s work supports Asset Management’s investment performance, scale, and efficiency.

Fidelity is transitioning to a full-time onsite working model through a phased regional and role-based rollout. Current onsite expectations vary; some roles and locations require 100% onsite presence, while others require less. Expectations may evolve during the rollout, which does not apply to fully remote roles. The job description does not specify the onsite expectation for this particular position.

Fidelity will not provide immigration sponsorship for this position. The base salary range is $126,000–$255,000 USD per year. Placement depends on responsibilities and scope, geographic location, relevant experience, and other factors. Depending on the position and eligibility requirements, the offer may also include bonus or other variable compensation. The application window closes when the position is filled or unposted. Fidelity’s regulated business may be restricted from hiring or associating with individuals with certain criminal histories.
