Full description
The Opportunity
Join a team building the data foundations that support the firm’s AI and analytics capabilities. This role sits within the engineering effort to develop a modern Lakehouse and AI data platform that enables reliable, well-governed and high-performing data use across the firm.
At Goldman Sachs, engineering teams are positioned at the centre of the business, building scalable systems, solving complex technical problems and turning data into action. In data engineering roles, the emphasis is on designing, building and maintaining large-scale data platforms, delivering production pipelines, improving reliability and quality, and partnering closely with users of the platform.
This is a delivery-focused role for engineers who want to build robust data assets in production, work with modern data technologies, and grow over time within the firm. You will contribute to the data models, pipelines and platform capabilities that underpin analytics, operational decision-making and emerging AI use cases.
Role Summary
As a Data Engineer, Lakehouse and AI Data Platform, you will design, build, test and support data pipelines and curated datasets on the firm’s modern data platform. You will work across ingestion, transformation, modelling, optimisation and data quality, helping to deliver data products that are reliable, scalable and fit for purpose.
The role is suited to engineers who are comfortable writing code, working with SQL and distributed data processing, and solving practical delivery problems in a team environment. More experienced candidates may also contribute to technical design, platform standards and the shaping of delivery approaches across a wider set of use cases.
Key ResponsibilitiesPipeline Engineering
- Build, enhance and support batch and streaming data pipelines on the Lakehouse and AI data platform.
- Refactor or modernise existing data flows where needed to improve reliability, performance and maintainability.
- Ensure data pipelines are production-ready, well tested and operationally supportable.
Data Modelling and Curation
- Develop raw, refined and curated datasets that support analytics, reporting and AI use cases.
- Apply sound data modelling principles to represent business entities, relationships and historical change accurately.
- Work with consumers to shape data products that are usable, well documented and aligned to business needs.
Data Quality and Reconciliation
- Implement controls to validate completeness, accuracy and consistency of data across pipelines and datasets.
- Use reconciliation approaches to build confidence in production outputs and investigate breaks where they arise.
