Principal AI/ML Engineer

About the role

Fidelity will not provide immigration sponsorship for this position.

Position Description

Builds and maintains large scale Machine Learning (ML) infrastructure, ML, data, and application pipelines, and evaluates ML models, using Apache Spark and distributed data processing frameworks. Establishes Python ML ecosystem using Object Oriented Programming (Java, Scala, and Python), SQL, and Unix scripting.

Leverages data movement technologies (Extract, Transform, Load (ETL)/ Extract, Load, Transform (ELT)), messaging and streaming technologies (AWS SQS, Kinesis, and Kafka), relational and NoSQL databases (DynamoDB, EKS, and Graph databases), and Application Programming Interface (API) and in-memory technologies.

Develops highly scalable distributed systems using Open-source technologies and Continuous Integration/Continuous Delivery (CI/CD) tools. Uses business knowledge to translate the vision for divisional initiatives into business solutions by developing complex ML infrastructure and conducting studies of alternatives.

Analyzes and recommends changes in project development policies, procedures, standards, and strategies to development experts and management.

• Builds sophisticated analytics, ML platforms, and software to enable moderl prediction and optimization.
• Develops highly scalable distributed systems and software applications using open-source technologies.
• Extends existing ML platforms and frameworks for scaling model training and deployment.
• Partners closely with business and software engineering teams to drive the adoption and integration of model outputs.
• Implements big data solutions in the data analytics space.
• Plans, creates, and maintains data architectures that are fully align with business requirements.
• Builds data flow channels and processing systems to ETL and integrate data from various sources.
• Confers with systems analysts and software engineers/developers to design systems and obtain information on project limitations and capabilities, performance requirements, and interfaces.
• Develops software system testing and validation procedures, programming, and documentation.
• Advises senior management on technical strategy.
• Mentors junior team members.
• Performs independent and complex technical and functional analysis for multiple projects supporting several divisional initiatives.
• Plans and coordinates complex project schedules and assignments for multiple projects.
• Responsible for meeting project goals on-time and on-budget.

Additional information

Fidelity is transitioning to a full-time onsite working model through a phased rollout across regions and roles. Currently, some roles and locations require 100% onsite presence, while others require less. Onsite expectations are likely to evolve as the rollout continues. This transition does not apply to fully remote roles.
