At NASK, we’re growing, building great teams, and doing exciting work. We are looking for a highly skilled Principal Database Architect / Lead DBA to design, implement, and own a high-performance database infrastructure from the ground up. You will be tackling complex data challenges at a massive scale. If you are obsessed with query optimization, latency reduction, and designing systems that can smoothly handle billions of rows without breaking a sweat, this is the role for you. In this position, you will bridge the gap between architectural design and hands-on implementation, ensuring our data layer is robust, highly available, and tuned to perfection.

  • Research, Architect, and Design database systems, solutions, and modern distributed architectures.
  • Optimize and Tune database performance, ensuring high performance, reliability, and scalability at a multi-terabyte or petabyte scale.
  • Manage Database Services and support migrations, operating in Linux/Unix environments.
  • Collaborate with Engineering Teams to plan for future changes, tune systems to meet evolving customer needs, and enable efficient information flow.
  • Deploy, Operate, and Monitor databases in Kubernetes and cloud environments.

Requirements & Qualifications

  • STEM Bachelor’s Degree in engineering, computer science, or information technology.
  • 5+ years of dedicated experience in database administration, architecture, and engineering at an enterprise scale.
  • Deep, hands-on expertise with Postgres, Oracle, MySQL, MariaDB, and MongoDB.
  • Experience optimizing and tuning databases for high performance and high availability.
  • Strong understanding of hardware limitations (I/O, CPU, Memory) and how they interact with database engines.
  • Experience managing and scaling multi-terabyte or petabyte-scale databases.
  • Software development experience, particularly interfacing with a database via Python on Linux.
  • Active Top Secret security clearance required to start.

Preferred Qualifications (if applicable)

  • Active TS/SCI w/poly security clearance.
  • Security+ (or higher) certification.
  • Industry-recognized certifications like Oracle Certified Professional (OCP), Microsoft Certified: Azure Database Administrator Associate, or AWS Certified Database.
  • Experience with Graph databases and NoSQL, as well as C/C++.
  • Familiarity with AWS Cloud products (EC2, EBS, S3, Lambda, Aurora, Dynamo DB, EMR, DMS, Athena, Glue, Kinesis, SQS/SNS).

Benefits & Perks (if applicable)

  • Competitive benefits package that equates to 50% on top of your annual base salary, split between a tax-qualified profit-sharing retirement plan and a cafeteria plan for benefits.
  • Individual offices and collaboration spaces.
  • Casual yet professional work environment with a strong focus on work-life balance.
