About the Job

Requirements

  • You have built and operated production data systems across ingestion, warehousing, orchestration, modeling, quality, and serving.
  • You are hands-on in SQL and Python and comfortable choosing and owning the surrounding tools.
  • You can turn broad goals into a clear sequence of work and take responsibility from initial design through reliable production operation.
  • You have worked with data from external organizations, not only clean application events.
  • You understand temporal modeling, idempotency, schema evolution, lineage, provenance, and how to establish trust when sources are incomplete or contradictory.
  • You can make important technical decisions without overbuilding and know which choices will be difficult to reverse, where correctness is essential from the beginning, and where a simple first version is appropriate.
  • You think beyond dashboards and analytical queries and are comfortable designing data systems that directly support applications, automated workflows, customer-facing experiences, and business operations.
  • You enjoy working with engineers, operators, and industry experts to turn complicated real-world concepts into clear models, interfaces, and systems.

Responsibilities

  • Own systems that move, transform, organize, and serve company data, including the data warehouse, ingestion and export infrastructure, orchestration and scheduling, transformation and modeling tools, semantic layers, data catalogs, quality, and observability.
  • Ingest and connect data from paid vendors, carriers, providers, government sources such as CMS, customer and benefits administration systems, public files, APIs, legacy portals, and company applications; build durable workflows for large files, changing schemas, incomplete records, and sources not designed to work together.
  • Design canonical models for plans, networks, providers, employers, members, claims, and other core concepts, preserving historical state, lineage, provenance, and source-specific nuance.
  • Make curated data available to the backend, member and employer experiences, AI agents, brokerage workflows, CRM, reporting, and operational tools; build reliable systems for moving data into and out of the warehouse.
  • Apply models and agents to acquire information from portals and older websites, interpret unfamiliar files, map changing schemas, reconcile conflicting sources, investigate quality issues, and automate traditionally manual work.
  • Work across product, engineering, brokerage, and operations to identify high-leverage data capabilities, prioritize the roadmap, and decide where durable infrastructure is needed and where a simpler solution can evolve.
  • Make early architectural decisions, build the first versions of data systems, and determine where rigor matters immediately and where simple systems can evolve.
  • Define how AI is used in data engineering to acquire, interpret, reconcile, and operate data more effectively.

About the Company

Malta

Provides rotational inertia via grid-scale storage

Malta Inc. provides grid-scale energy storage to turn variable renewable resources into reliable on-demand power. Its system stores energy and adds rotational inertia to the electricity grid, delivering up to 100 MW of capacity as needed. The technology uses readily available components and is designed to be terrain-independent, so it can be scaled to different locations. This makes it suitable for utilities and government projects seeking stable, cost-competitive storage to support a low-carbon energy mix. Malta differentiates itself through scalable, land-agnostic storage that also adds grid inertia, backed by partnerships with the German government and the DLR national laboratory to support a shift away from natural gas. The company aims to help the energy system move toward renewable sources by providing dependable storage solutions and collaborating with public partners to fund and deploy them.
