First seen by Alion on Oct 20, 2026.
TechBar is a software services company working with clients across the US and Europe. We are investor-backed, growing steadily, and known for putting senior, thoughtful engineers in front of our clients.
We are looking for a Senior Data Engineer to join our client’s team at a wealth management firm modernizing its data platform using Databricks and AWS.
About the Project
You will design, build, and maintain reliable data pipelines and lakehouse models that power analytics, reporting, and data products across the business.
The platform processes financial data, including client portfolios, transactions, positions, and performance. Some initiatives may involve migrating existing workloads from Snowflake to Databricks.
Responsibilities
Build the lakehouse: Design and develop scalable batch and streaming pipelines on Databricks using Spark and Delta Lake, following a medallion architecture (Bronze / Silver / Gold).
Own data on AWS: Work with S3, IAM, and related AWS services to ingest, store, and secure data from internal systems and third-party financial data providers.
Model for the business: Build clean, scalable, and well-documented data models for analytics, reporting, and downstream consumers.
Ensure data quality and trust: Implement data quality checks, monitoring, and lineage. Manage access and governance using Unity Catalog.
Optimize performance and cost: Tune Spark jobs, cluster configurations, and storage layouts to improve performance and control cloud costs.
Automate delivery: Apply CI/CD and infrastructure-as-code practices to Databricks workflows and environments.
Support migration: Assess and migrate data pipelines, models, and workloads from Snowflake to Databricks where needed.
Collaborate: Work closely with analysts, data scientists, and business stakeholders to translate requirements into reliable data solutions.
