Technical Competency

This area is the foundation of your candidacy. Interviewers are looking for evidence that you can build and maintain scalable, reliable systems.

Be ready to go over:

• ETL/ELT Design – Explain your process for mapping sources to targets and handling schema evolution.
• Cloud Proficiency – Discuss your familiarity with AWS or Azure services relevant to data ingestion, storage, and processing.

As a Data Engineer, your primary objective is to build the infrastructure that powers the firm's analytics. You will spend a significant portion of your time designing and implementing ETL/ELT pipelines, ensuring that data flows seamlessly from various sources into the environments where it can be processed. You are also responsible for developing cloud-based data solutions, which requires a strong understanding of how to manage data at scale within secure cloud environments.

Beyond building, you will play a critical role in the maintenance and optimization of these systems. This involves regular troubleshooting of pipelines, building automated workflows, and managing API integrations. You will work in a hybrid environment, collaborating closely with analysts and data scientists to ensure that the data you provide is clean, governed, and fit for purpose. Your work directly supports Pantheon Data’s ability to provide high-quality services to federal and commercial clients.

To be competitive for this position, you must demonstrate a mix of technical certifications and hands-on professional experience.

• Must-have skills:

  • Bachelor’s degree in a relevant technical field.
  • At least 4 years of data engineering experience (or 3 years with a Master’s degree).
  • Current certification in AWS (Data Engineer Associate/Data Analytics) or Azure (Data Engineer Associate).
  • Proficiency in Microsoft Suite (Outlook, Excel, SharePoint, etc.).
  • Ability to obtain and maintain Public Trust clearance.

• Nice-to-have skills:

  • Experience in government contracting environments (DHS/DoD).
  • Exposure to metadata management and formal data governance frameworks.
  • Strong documentation habits that support team-wide knowledge sharing.

Q: Is the interview process difficult? A: Candidates describe the process as standard but thorough. While not designed to be "trick-heavy," it is rigorous regarding your technical foundations and your ability to work in a client-facing, professional environment.

Q: How much time should I spend preparing? A: Dedicate at least one to two weeks to review your cloud architecture knowledge and practice explaining your past projects. Ensure you can articulate the "why" behind your technical choices, not just the "how."
