About the Role
We're looking for a Senior Data Scientist to help deliver data science and business analytics solutions for our fintech clients.
This is a hands-on, senior individual-contributor role. You'll spend most of your time deep in the data building models, running analysis, and shipping work that clients act on — while taking full ownership of your workstreams and helping level up more junior members of the team.
The role centers on three things:
● Deep technical craft — you're excellent in the data and hold a high bar for your own work.
● Ownership of delivery — you own your workstreams end-to-end, from ambiguous problems to clear
recommendation, and you deliver reliably.
● Clear communication — you present findings with confidence, work directly with clients in your
areas, and explain complex ideas simply.
If you love being close to the work, take pride in producing rigorous analysis, and enjoy turning messy
problems into clear answers, we'd love to talk.
Key Responsibilities
Hands-On Data Science & Analytics
● Write SQL and Python, build models, run analysis, and create dashboards — this is the core of the
role, day in and day out.
● Design, build, and deploy end-to-end ML models for lending use cases such as credit scoring, risk
assessment, default and early-warning prediction, fraud detection, and customer segmentation.
● Own the full modeling lifecycle: exploratory analysis, feature engineering, model selection,
validation, and performance monitoring.
● Partner with client stakeholders to answer key business questions with data — running ad hoc
deep-dives and recurring analyses that inform product, risk, pricing, and operational decisions.
● Own portfolio and performance analytics — tracking and explaining metrics such as application
and funding conversion, approval rates, delinquency, charge-offs, roll rates, and vintage/cohort
performance.
● Credit Risk Analytics to evaluate changes to credit policy, product, and pricing, and translate the
results into clear, actionable recommendations.
● Design intuitive Tableau dashboards and automated reporting that drive decisions across product,
risk, and operations.
● Follow and help improve best practices for reproducible, scalable, production-ready work.
Delivery & Client Collaboration
● Own the delivery of your workstreams end-to-end — scoping, planning, execution, and on-time
delivery.
● Work directly with client stakeholders on your areas of the project, building trusted relationships
and staying close to their needs.
● Translate ambiguous, open-ended business problems into well-defined analyses with clear
deliverables and timelines.
● Communicate progress clearly, surface risks early, and keep your work on track.
● Present findings and recommendations to both technical and executive audiences with clarity and
confidence.
Mentorship & Quality
● Mentor junior data scientists and analysts, sharing your expertise and helping them grow.
● Bring a quality-first mindset to your own work, and contribute to code, model, and dashboard
reviews to help maintain a high bar across the team.
● Contribute to the team's technical standards and best practices.
● Help unblock teammates and support them on both technical craft and communicating their work.
● Contribute to a culture of curiosity, ownership, and continuous improvement.
What We’re Looking For
Must-Have:
● 4+ years of hands-on experience in data science / business analytics, with a track record of owning
meaningful workstreams and delivering high-quality work.
● A strong sense of ownership — managing your scope, timelines, and stakeholders to deliver
reliably.
● Expert SQL for querying and shaping large-scale datasets.
● Strong Python for data analysis and ML modeling.
● Hands-on expertise with Tableau (or a similar BI tool) for dashboarding and reporting.
● Deep understanding of statistics, hypothesis testing, and data visualization best practices.
● Strong experience with ML libraries/frameworks (e.g., scikit-learn, XGBoost, TensorFlow, PyTorch).
● Experience taking ML models from prototype to production.
● Excellent communication and presentation skills — able to explain complex technical concepts to
non-technical and executive audiences, and comfortable presenting your work directly to clients.
● A quality-first mindset: strong attention to detail and pride in producing rigorous, reliable work.
● Bachelor's or Master's degree in Computer Science, Engineering, Statistics, or a related quantitative field.
Nice-to-Have:
● Background in fintech, credit risk, or lending — a strong plus that will help you ramp quickly with the
client.
● Experience mentoring junior data scientists or analysts.
● Experience with cloud data platforms (AWS, GCP, Azure).
● Familiarity with MLOps and model deployment pipelines.
● Experience in a consulting environment.
● Comfort working with US-based / distributed clients across time zones.
● Knowledge of Git, CI/CD, and modern data workflows.
What Success Looks Like
● First 30 days: You've ramped up on the client's data and priorities, built good working relationships
with the team, and taken ownership of your first workstreams.
● Within 3 months: You're consistently shipping high-quality, high-impact work, trusted to run with
complex problems on your own — and you've become a go-to technical contributor the client and
team rely on.
