HPC Systems Administrator, CNO Infrastructure

An active TS//SCI clearance with polygraph is required for this role

Hey!

Bitwise is a leading provider of mission-focused intelligence solutions that advance national security for the Intelligence Community and Department of Defense. We're a small and growing company, so you can expect to hop in on the ground floor with us and be a consequential member of the team. You'll be more than a contract performer for us — you'll also be asked for ideas to improve our company and improve your career, and you'll contribute to our team culture. We value growth and community above almost all else, so we gather regularly for game nights, happy hours, tech talks, and plenty more. We think you'll like it here!

Remember, Bitwise is not a cult.

What We Look For

Bitwise hires talented engineers who are driven by purpose and who value a culture of technical excellence, growth, and overall wellness. We deliver new and innovative intelligence solutions to our customers at the very forefront of our country's national security missions. And we do it every single day. Our work matters, and so will you.

We ask that every new hire be able to:

• Contribute meaningful thought leadership — if not right away, over time
• Interact with our customers and earn their confidence in your abilities
• Be detailed, even if that means taking a little more time to get it right
• Contribute their ideas and ideals to improve all aspects of our company
• Allow us to invest in their education so we both grow together
• Know and live our core values every single day

About this Role

We're looking for a senior System Administrator who will take ownership of sustaining and evolving a high-performance operational IT environment supporting critical national security capabilities. This is not a ticket-only role — you'll be a technical contributor who drives real impact every day.

You will install, configure, and maintain high-performance compute hardware while managing installation and sustainment efforts for both new and legacy systems within our datacenter environment. You'll use configuration management tools like Ansible to build repeatable, scalable deployment playbooks and create precise documentation of procedures, configurations, and lessons learned that allows any engineer to step in seamlessly.

You'll work directly with users and distributed support teams to identify gaps in onsite support coverage, recommend improvements to reduce downtime, and optimize workflows. You'll maintain technical documentation, diagrams, and standard operating procedures with exceptional clarity. You'll also support virtualization efforts and contribute to IT modernization strategies as mission requirements evolve.

This role demands someone who is forward-leaning, takes initiative, and actively looks for ways to make the work easier and faster for everyone around you.

Requirements

• 9+ years of relevant experience (with or without a B.S. degree)
• Strong Linux administration skills
• Networking expertise
• Proficiency in VMware virtualization
• Hands-on experience with configuration management (Ansible)
• Patch management and user management capabilities
• STIG mitigation knowledge
• Ability to document technical processes with clarity and precision
• Strong problem-solving skills
• Excellent communication skills when interacting with customers and team members
• Ability to operate independently while coordinating effectively with distributed support teams

Preferred Skills

• Out-of-band (OOB) management experience
• Kubernetes experience
• High availability web services knowledge
• Hands-on comfort working with hardware
• Growth-oriented mindset with interest in expanding technical knowledge
