Responsibilities

Position Purpose: We are seeking a Data Science Lead to join the Global Data & Insights team in Bogota. This role will lead a small team delivering applied analytics, machine learning, and data product solutions for global business and technology stakeholders.

The Data Science Lead is accountable for both technical quality and delivery outcomes. This person will take business and technical priorities from intake through execution, structure the work for the team, guide day-to-day delivery, manage stakeholder expectations, and ensure work is completed to a standard that can be adopted, supported, and scaled.

This is a leadership role for someone who is still close enough to the work to challenge assumptions, review technical approaches, unblock the team, and connect model development to real business outcomes.

Primary duties will include:

• Lead, coach, and develop a small team of data scientists and analysts, creating clear expectations for ownership, quality, communication, and delivery.
• Translate business and technology priorities into well-scoped data science workstreams, including problem definition, success criteria, required data, delivery plan, and stakeholder alignment.
• Assign and guide work across the team, monitor progress, remove blockers, and ensure delegated work reaches completion without requiring continuous escalation.
• Provide technical leadership across exploratory analysis, feature definition, model development, evaluation, documentation, and implementation handoff.
• Partner with business stakeholders to understand operational, commercial, market-data, or workflow problems and determine where analytics or machine learning can create practical value.
• Collaborate with data engineering, application engineering, and platform teams on data pipelines, model-serving patterns, API integration, testing, and production readiness.
• Ensure models and analytical outputs are documented clearly, including assumptions, limitations, business context, model logic, implementation notes, and support considerations.
• Communicate progress, risks, tradeoffs, and recommendations clearly to both technical and non-technical stakeholders.

Representative Areas of Work

• Machine learning classification, scoring, prediction, and decision-support use cases.
• Operational analytics, including exception analysis, settlement or failed-trade analysis, and workflow optimization opportunities.
• News, content, market-data, or commercial analytics solutions that need to move from analysis into user-facing or business-facing workflows.
• Databricks-based experimentation, model development, documentation, code review, and team handoff practices.
• Model-serving and integration patterns, including REST APIs, inference workflows, feature pipelines, and downstream system adoption.
• Batch and streaming data use cases involving collaboration across analytics, data engineering, and application teams.

Qualifications

To land this role you will need:

• Bachelor's degree in Computer Science, Data Science, Statistics, Engineering, Mathematics, Economics, Finance, or a related quantitative field, or equivalent professional experience.
• Meaningful experience in data science, machine learning, analytics, or data product delivery, with demonstrated ownership of complex analytical or ML initiatives.
• Experience leading, managing, mentoring, or formally guiding a small technical team.
• Strong hands-on capability with Python and SQL, with enough technical depth to review team output and guide solution design.
• Experience developing, evaluating, and explaining machine learning models for business or operational use cases.
• Understanding of production considerations for data science solutions, including data quality, pipelines, model serving, API integration, monitoring, documentation, and maintainability.
• Strong stakeholder management skills, including the ability to clarify ambiguous asks, manage expectations, and communicate technical tradeoffs in business language.
• Demonstrated ability to manage multiple workstreams and drive team delivery through completion.

What makes you stand out:

• Experience with Databricks, Spark, notebooks, MLflow, or comparable cloud-scale analytics platforms.
• Experience with REST APIs, JSON payloads, model inference endpoints, MLOps workflows, or application integration patterns.
• Experience with streaming or event-driven platforms such as Redpanda, Kafka, or similar technologies.
• Experience in financial services, capital markets, commodities, trading operations, settlement, market data, CRM, commercial analytics, or news/content analytics.
• Experience building team routines for intake, prioritization, code review, documentation, delivery tracking, and stakeholder communication.
• Experience working in a global organization across time zones with business, data, engineering, product, and technology leadership stakeholders.

Success Profile

• A trusted owner who can take an ambiguous priority, structure the work, guide the team, and deliver without excessive oversight.
• A team multiplier who improves quality and throughput through coaching, standards, review, and clear operating rhythm.
• A pragmatic technical leader who knows when a model is useful, when the data is not ready, and when a simpler analytical solution is more appropriate.
• A strong communicator who can explain assumptions, limitations, risks, and recommendations clearly to senior stakeholders.
• A delivery-focused leader who balances experimentation with adoption, supportability, and production realities.

Working environment

• Hybrid 4 days in office per week (Office location: Avenida Carrera 9A - Avenida Carrera 9A # 115-06/30 Edificio Torre Tierrafirme Bogotá, 110111 Colombia)
