Data Engineer Contract Jobs in Allen, TX (NOW HIRING)

Summary/Objective

The Lead Data Engineer owns the Navanta data backbone - public Call Report data in the early build, and secure ingestion from bank cores into lakehouses as each client's on-premises environment is stood up. Working under the SVP of Technology and Commercial AI and in close partnership with the AI/ML, security, and platform teams, this role builds the architecturally clean, well-modeled, reconcilable data foundation that makes it possible for the Navanta AI platforms to give numbers a banker will act on.

Essential Functions

    Design the lakehouse: Apache Iceberg (or similar technology) on object storage, a catalog for table management and per-bank isolation, dbt models, and a query engine

    Build secure, least-privilege ingestion from bank systems - log-based CDC where permitted, with query-based and batch/SFTP fallbacks, plus an in-bank collector pattern

    Own data modeling for the semantic and metric layer (deposits, concentration, uninsured exposure, asset quality, and peer groups)

    Handle schema drift, data quality, and reconciliation; make ingestion observable and recoverable

    Partner with the AI/ML team on the structured-query path and with Security on PII classification at landing, in alignment with regulatory data-handling requirements

    Document data lineage, transformation logic, and access controls to support audit and exam readiness

    Define and enforce data contracts, quality thresholds, and alerting for pipeline failures

Core Competencies

    End-to-end ownership of ingestion-through-serving pipelines, with a bias toward reliability and observability

    Rigorous data modeling for analytics - semantic layers, metric definitions, and reconcilable outputs

    Security and compliance mindset: PII handling, least-privilege access, and data governance aligned to regulatory guidance

    Cross-functional partnership with AI/ML and platform engineering to deliver governed, queryable data products

KPIs

    Data freshness and pipeline reliability - SLAs met for data ingestion and bank-core feeds

    Data quality score across key metrics versus source reconciliation

    Time to onboard a new bank's data environment, from kickoff to queryable lakehouse

    PII classification coverage at landing and zero unauthorized data-access incidents

    Semantic layer adoption - percentage of assistant queries resolved via governed metrics versus ad hoc SQL

Qualifications

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required.

    8-12+ years in data engineering with end-to-end ownership of ingestion through serving, and 2+ years in a lead or senior role

    Strong Python and expert SQL; rigorous data modeling for analytics

    Hands-on lakehouse experience (Iceberg/Delta/Hudi or equivalent) and modern transformation tooling

    Built reliable pipelines from messy operational and transactional source systems

    Comfort with CDC mechanics and the realities of pulling from databases you do not control

Core Technologies

    Languages: Python, SQL (deep)

    Lakehouse & catalog: Apache Iceberg; Polaris / Nessie / Lakekeeper

    Transform & query: dbt; Trino / Presto / DuckDB

    CDC & streaming: Debezium (SQL Server CDC, Postgres logical replication), Kafka / Redpanda

    Orchestration: Dagster (or Airflow)

    Storage: S3 / MinIO

    SQL Server and PostgreSQL data modeling, pgvector (or equivalent)

Nice to Have

    Experience with financial or core-banking data, or FFIEC / Call Report data specifically

    Strong SQL Server familiarity

    Data contracts, lineage, and governance practices

Education and/or Experience

    Bachelor's degree in computer science, mathematics, information systems, or a related field, or equivalent hands-on experience

    Experience in the financial services industry or a regulated data environment strongly preferred

Work Structure & Expectations

    Full-time role combining ongoing pipeline operations with initiative-based lakehouse build-out and new bank onboarding

    Close collaboration with AI/ML, platform engineering, and security teams; on-call rotation covering data pipeline reliability
