Senior Fintech Data Scientist Jobs (NOW HIRING)

The Data Scientist position is in the Logicpath division within Loomis. We are a team of tech-savvy cash inventory management experts passionate about helping financial institutions succeed. 

We provide a collaborative and supportive environment that values the participation and contribution of all employees. We are looking for people who want to be challenged, solve complex problems, and feel connected to a larger purpose. Our mission-focused team, collaborative nature, and commitment lead to dedication to client results. 

The Data Scientist will play a critical role in designing, scaling, and operationalizing advanced analytics and machine learning solutions across the company’s FinTech platforms. This role will lead complex forecasting initiatives, develop AI-driven use cases (including LLM-enabled support tools), and establish strong data quality and model governance practices.

This position requires a hands-on technical leader who can translate real-world operational and financial problems into robust, production-ready data science solutions, while partnering closely with engineering, product, implementation, and client-facing teams.

The ideal candidate combines strong statistical and machine learning expertise with practical engineering ability and a track record of delivering production-grade solutions in environments where communication, business processes, data quality, and operational constraints matter as much as model performance. This very technical person is capable of thinking in terms of “problem -> solution -> product -> value”, not just “models”.

Key Responsibilities 

Forecasting & Advanced Analytics

•  Lead the design, development, and optimization of forecasting models for:

o Cash demand (branches, ATMs, retail locations, vaults)

o Labor and operational workload forecasting

• Apply and evaluate time-series, probabilistic, and machine-learning techniques to improve forecast accuracy and stability.

• Own model performance monitoring, drift detection, recalibration strategies, and continuous improvement.

AI, ML, & LLM Enablement

• Design and implement LLM-based use cases to support internal teams (e.g., support, implementation, operations).

• Develop approaches for prompt engineering, evaluation, and governance of LLM outputs.

• Partner with engineering to integrate AI capabilities into production SaaS workflows.

•  Define metrics to measure effectiveness, accuracy, and operational impact (ROI) of AI solutions.

Data Quality, Governance & Model Risk

•  Establish data quality frameworks to detect anomalies, gaps, and integrity issues across large transactional datasets.
• Define validation rules, thresholds, and scoring mechanisms to support data confidence and forecast reliability.
• Contribute to model documentation, explainability, and governance practices aligned with financial services expectations.
• Support audit, compliance, and client due diligence inquiries related to data and models.
• Technical Leadership & Collaboration

   Required Qualifications

• 6+ years of professional experience in data science, machine learning, or advanced analytics
• Advanced proficiency with Python and data science libraries (e.g., pandas, NumPy, scikit-learn, TensorFlow/Torch)
• Strong SQL skills and experience working with messy, incomplete, high-volume operational data
• Well-rounded background in data science methods (e.g., supervised and unsupervised learning, anomaly detection, time series forecasting, survival analysis, simulation, optimization, causal analysis)
• Familiarity with metric design
• Demonstrated delivery of products that influenced business decisions
• Experience collaborating with engineering teams on model deployment and monitoring.
• Proven ability to communicate complex concepts clearly and effectively.

Preferred Qualifications

• Experience in FinTech, banking, payments, retail cash management, or operations
• Experience identifying high-value data science opportunities in operational businesses
• Hands-on LLM development experience
• Familiarity with data quality and model governance frameworks

Ideal Candidates are:

• Comfortable with ambiguity
• Driven to elevate themselves by elevating others
• Curious and lifelong learners
• Able to identify valuable problems before being asked
• Pragmatic rather than purely academically focused
• Capable of explaining very technical ideas to non-technical stakeholders
• Willing to challenge their own and others’ assumptions with evidence
• Open to changing their mind when presented with new evidence

What Success Looks Like

· Forecasting models that are accurate, explainable, and trusted by clients and internal teams.

· AI and LLM use cases that measurably reduce operational effort and improve response quality.

· Strong data quality visibility that proactively identifies issues before they impact forecasts.

· Clear, well-documented models and methodologies that scale across clients and use cases.

· A collaborative, high-impact partnership with engineering, product, and client
