Sr Data Architect

Apex Systems
Milwaukee, WI Full Time
POSTED ON 4/25/2026
AVAILABLE BEFORE 5/25/2026
Job#: 3023336

Job Description:

Overview

The client is seeking a Senior or Lead-level Data Platform Consultant to support the Wealth Engineering team in designing and implementing a modern data ingestion and platform architecture. The primary focus of this role is enabling Snowflake-based data sharing from third‑party vendors and integrating that data into an AWS-native data ecosystem, while helping evaluate longer-term architectural decisions.

This is a hands-on role with some advisory responsibility, but it is not a purely strategic or “ivory tower” position. The consultant will work closely with a Principal Software Engineer and internal data teams to execute, validate design decisions, and accelerate delivery of a business-critical initiative.

Key Responsibilities

Data Ingestion & Integration

  • Design and implement ingestion patterns using Snowflake Private Data Shares as the primary source of data.
  • Configure and manage Snowflake streams and change data capture to support incremental updates.
  • Support ingestion from non-Snowflake sources, including:
    • Vendor flat files (e.g., S3-based file drops)
    • External APIs requiring Python-based ingestion.
  • Enable more frequent data refreshes (near–real-time or hourly), reducing reliance on heavy nightly batch processes.

Platform Architecture & Execution

  • Collaborate with internal engineering leadership to evaluate:
    • Keeping data and transformations within Snowflake, versus
    • Using Snowflake primarily as an ingestion layer and landing data in AWS (S3 Iceberg).
  • Provide practical input on architectural tradeoffs, including:
    • Performance
    • Cost
    • Developer experience
    • Long-term maintainability
  • Implement solutions aligned with the client’s AWS-native enterprise standards, including interoperability with existing data platforms.

AWS & Data Lake Enablement

  • Work extensively with AWS services, including:
    • S3
    • AWS Glue (catalog integration)
    • Iceberg tables
  • Support integration with enterprise governance tooling (e.g., Glue Catalog / Lake Formation), following existing organizational patterns.
  • Assist with data replication patterns where data must serve downstream APIs or operational use cases.

Transformation & Analytics Support

  • Support or implement data transformations using dbt if data remains within Snowflake.
  • Ensure strong SQL-based modeling practices.
  • Contribute to creating reliable, reusable datasets and data products for internal consumers.

Advisory & Collaboration

  • Act as a senior individual contributor who can:
    • Identify blind spots in proposed designs
    • Share best practices from prior Snowflake AWS implementations
    • Help the team validate assumptions before scaling solutions
  • Work closely with internal engineers rather than owning strategy independently.
  • Participate in solution discussions with internal stakeholders and partner teams.

Required Skills & Experience

Core Technical Skills

  • Strong hands-on experience with Snowflake, including:
    • Private Data Shares
    • Streams / change tracking
    • General Snowflake administration related to data ingestion
  • Deep experience with AWS, specifically:
    • S3
    • Glue Catalog
    • Iceberg tables
  • Advanced SQL skills.
  • Strong Python experience for:
    • API-based ingestion
    • Data manipulation (not SQL-only usage).
Data Engineering Background

  • Experience building and operating production-grade data pipelines.
  • Comfort working across multiple ingestion patterns (Snowflake shares, files, APIs).
  • Ability to balance performance, cost, and maintainability.

Senior-Level Expectations

  • Ability to operate independently with minimal oversight.
  • Comfortable advising but also executing.
  • Pragmatic, delivery-focused mindset.

Nice-to-Have Qualifications

  • Experience with dbt in Snowflake environments.
  • Prior exposure to wealth management, asset management, or financial data domains (not required).
  • Experience supporting data platforms that feed operational APIs, not just analytics.
