About the job

About Us

At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we’re building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.

Formed in 2023, the Antares team hails from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, Ultra Safe Nuclear, and Los Alamos National Laboratory. Antares has raised over $39M in venture capital from top-tier investors and has over $4M in government funding.

About the Team

As an early member of the Antares operations team, you will define, implement, and maintain the information technology, cybersecurity, and networking strategy for the company. This will include creating a scalable technology stack that enables the company to operate at a startup pace while introducing the framework for future security, export, and compliance controls. This is a critical role that is a multiplier for the company in enabling seamless collaboration internally and with customers, and will interact with all functions to capture requirements across the business.

The ideal candidate will be able to execute in an ambiguous environment, with the ability to efficiently balance many different priorities – you will both be responsible for executing a strategic vision and ensuring the day-to-day stability of the company operations, with significant influence as an early team member.

Roles & Responsibilities:

  • Define and execute a comprehensive technology roadmap that balances near-term agility, robust security measures, and readiness for future growth

  • Oversee and implement cybersecurity standards such as NIST SP 800-171 and CMMC (Cybersecurity Maturity Model Certification), including the required documentation and procedures that comply with customer or government contract requirements

  • Develop protocols and systems for complying with ITAR, EAR, DFARS, and other regulatory requirements

  • Establish processes for handling Controlled Unclassified Information (CUI) and export-controlled data, including data classification, storage, and incident response

  • Coordinate with external auditors and internal stakeholders to ensure continuous compliance and readiness for government audits

  • Oversee the design, deployment, and maintenance of local and cloud-based infrastructure, networking solutions, and end-user computing environments

  • Define and manage budgets for hardware and software expenditures, balancing throughput and performance with cost

  • Manage vendor relationships and contract negotiations to ensure cost-effective procurement and service-level agreements

  • Establish and lead user support functions, including helpdesk operations, training, and documentation

  • Address urgent blockers to ensure an always-working, always-on infrastructure

Basic Qualifications:

  • Bachelor’s degree in information technology or systems, cybersecurity, engineering, computer science, math, physics, or data science

  • 5+ years of experience implementing and managing a broad IT stack including hardware and software

Preferred Skills & Experience:

  • Proficiency in implementing and managing FedRAMP compliant systems, successfully creating and incorporating CMMC or NIST standards, or developing controls for handling export-controlled data or CUI

  • Demonstrated track record of managing hardware or software in an agile and dynamic work environment

  • Experience implementing policies or procedures for a government contractor

  • Proven success in a start-up environment or similar, with the ability to manage ambiguity and wear many different hats

  • Excellent listener and communicator, with demonstrated ability to collaborate with many different stakeholders

Additional Requirements:

  • Ability to work long hours and weekends as necessary to support critical milestones

Culture

At Antares, we like to specifically tie each role to our founding document’s set of values–here are the top five cultural values we think you should believe at your core to be successful:

  • Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. “If you want to be certain, then you are apt to be obsolete.” Over-optimizing the components often degrades the system.

  • Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle

  • Be Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's “how it's always been done.”

  • Craftsmen - We also focus on the inputs. We aspire to high-quality engineering for its own sake. As such, we invest in personal growth, learning, and developing a long-term career path for exceptional individual contributors. We embrace a beginner’s mindset, share knowledge, and never condescend the curious.

  • Seriously Optimistic - We’re ambitious and we believe we’re capable of achieving things others believe are impossible. We reward audacity, and don’t let cynicism, sarcasm, snark, or belittlement influence us to lower the bar
