Position Summary ARC Energy Services is seeking a Data Engineer to join our Technology team in Rock Hill, SC. You will build and maintain the data platform and internal applications that run our business: the systems our recruiting, payroll, operations, and quality teams use every day to staff projects, track time and pay, and keep our field workforce qualified and compliant. This role reports to the head of Technology.
The work is roughly half data engineering and half internal application development. The data work is the foundation: pipelines, data models, and integrations with systems such as QuickBooks, Salesforce, and our HR, recruiting, and payroll platforms, built on Databricks and PostgreSQL in Microsoft Azure. On top of that, you will build features in our internal web portal using TypeScript and React. Strong data engineering skills are required. Application development experience is a plus, and we will train you on it.
We are a small team that builds with AI coding assistants every day, and we expect you to review, test, and stand behind everything you ship. You will own systems that people across the company depend on, work directly with the people who use them, and see the results of your work quickly. Essential Duties and Responsibilities

• Build and maintain data pipelines in Databricks that bring in data from business systems such as QuickBooks, Salesforce, and HR, recruiting, and payroll platforms.
• Design and maintain the data models and SQL views behind reporting, analytics, and the internal portal.
• Build and improve features in the internal web portal, from database queries and server logic to the screens people use, with training and support on the application side.
• Keep data accurate where it matters most: hours, pay, worker qualifications, and matching the same person across multiple systems.
• Investigate and resolve data and application issues reported by users, including time-sensitive problems around payroll deadlines.
• Make database and schema changes carefully, with testing and peer review before they reach production.
• Use AI coding assistants as part of daily development, and review, test, and verify their output before it ships.
• Work directly with recruiting, payroll, operations, and quality teams to understand their needs and turn them into working tools.
• Document data sources, pipelines, and application features so others can support them.
• Follow company security practices for handling sensitive employee and payroll data.

Minimum Qualifications

• Bachelor's degree in computer science, information systems, engineering, or a related field, or equivalent practical experience.

• Experience with at least one cloud data platform, such as Databricks, Snowflake, BigQuery, or Redshift.
• Experience with Git and code review workflows.
