Data Steward

Role Overview

We're looking for a Data Steward who's excited to sit at the intersection of financial-market data and AI — someone who cares as much about getting a definition exactly right as they do about seeing that definition come alive inside an AI agent's response. This role combines two closely connected responsibilities: end-to-end stewardship for assigned financial-data domains, and the development of Snowflake semantic layers and prompts that power AI-driven data products. You'll move fluidly between governing and improving data at the source and shaping how that data is structured, understood, and surfaced for AI agents and applications — helping turn complex financial data into something people and machines alike can trust.

You'll be a strong fit if you have:

● Experience in data management, data governance, or data stewardship, ideally in financial services / capital markets

● Working knowledge of Snowflake (or a comparable cloud data warehouse) and SQL

● Experience with at least one of: securities/instrument reference data, trading lifecycle data, risk or market data

● Interest or prior experience in prompt engineering, semantic modeling, or AI-agent enablement

● Strong communication skills — able to translate technical data concepts into clear business language for engineers, business stakeholders, and clients

Responsibilities

AI-Driven Data Product Development

● Build, maintain, and enhance semantic layers in Snowflake that provide the structure, definitions, relationships, and business context AI-driven products need

● Ensure data exposed through semantic layers is clearly defined, discoverable, consistent, and suitable for consumption by AI agents and applications

● Apply prompt engineering to develop, test, evaluate, and refine prompts and prompt patterns that improve accuracy, relevance, and consistency of AI-generated responses

● Translate complex financial-data concepts into semantic models, metadata, prompts, and instructions for AI-driven solutions

● Identify and close gaps in data, definitions, context, prompts, or user requirements that limit AI output quality

● Support agent reliability by ensuring AI outputs are grounded in accurate, well-governed data

Data Stewardship & Domain Ownership

● Own end-to-end stewardship for assigned data domains: definition, documentation, governance, quality control, and continuous improvement

● Establish and monitor data-quality rules, controls, and KPIs (e.g., % fields with business definitions, SLA for issue resolution, quality-score trends)

● Investigate data-quality issues, drive root-cause analysis, and coordinate resolution with engineering and product teams

● Assess impact of proposed data changes on downstream consumers before they ship; perform QA/validation prior to production release

● Maintain documentation: business definitions, ownership, lineage, usage guidance, known limitations

● Act as the trusted point of contact for assigned domains, communicating data-quality risks, changes, and limitations proactively to stakeholders and clients

L2 Support & Operations

● Serve as L2 support for data incidents, questions, and production issues within assigned domains

● Diagnose whether root cause is source data, transformation logic, business rules, or semantic definition

● Plan remediation for identified issues and communicate progress and impact clearly to related teams
