Job description

Atomus’ mission is to provide world‑class cybersecurity for the world’s most critical organizations. We sell security compliance infrastructure to aerospace and defense companies that need to meet NIST SP 800‑171, DFARS 7012 and CMMC requirements. Customers don’t have to build, maintain, monitor and document their own IT infrastructure for audit. Instead, they onboard to our pre‑built, pre‑compliant infrastructure, which we deliver as a managed service along with professional services and support. Our customers include hypersonic aircraft companies, satellite and space mission systems companies, and AI and software companies, among many others. At Atomus, we work hard, move fast and put our customers first.

About the Role

As a Cybersecurity Analyst, you will work closely with customers to help them implement and get the most out of Atomus’ cybersecurity products. You’ll also help them stay compliant with NIST SP 800‑171 and CMMC and solve their technical problems. Customers rely on Atomus to manage and secure their Windows, macOS, Ubuntu, iOS and Android devices and their firewalls, all while keeping them compliant. Our goal is to make security and compliance simple for them. You’ll be the voice of the customer, passing their feedback to our product team and reporting issues to our software engineers.

This role is your entry point to the Atomus cybersecurity team. Over roughly 18 months, you’ll rotate through our three core functions. Then you’ll move into one of them as your specialization:

• Cybersecurity Engineer: Deploy, configure and troubleshoot the security stack, working with customers on their security infrastructure.
• GRC Analyst: Run risk assessments, maintain compliance documentation, and lead quarterly compliance reviews and CMMC assessment prep with customer leadership.
• IT Project Manager: Own end-to-end onboarding for new customers, coordinating between customers, IT vendors and engineering.

What You’ll Do

• Guide new customers through onboarding. This means making sure everything is set up and configured correctly, aligning with their security programs, establishing baseline NIST SP 800‑171 and CMMC compliance, and running the technical tasks and project management each onboarding needs.
• Serve as the first point of contact for technical questions, debugging and resolving IT and security issues related to the Atomus platform.
• Work with internal teams (sales, product, engineering) and with partners and vendors, sharing customer feedback and advocating for customer needs in product development and third‑party rollouts.
• Help customers maintain NIST SP 800‑171 and CMMC compliance by keeping their IT documentation current and audit‑ready.

Required Skills

• Experience in a customer‑facing technical role, such as IT administrator, solutions engineer, technical customer success manager or TAM, ideally in cybersecurity or compliance.
• Working knowledge of security technologies such as firewalls, routers, switches and encryption tools.
• Intermediate networking knowledge, including WAN/LAN connectivity.
• Hands‑on experience with Microsoft products and services: Intune, Active Directory, Exchange, SharePoint, Windows and Windows Server.
• Experience managing macOS through Apple Business Manager (ABM) and mobile platforms (iOS, Android).
• Familiarity with command‑line tools (e.g., PowerShell, Terminal) for troubleshooting and deployment.
• Strong troubleshooting skills across network security, software and IT environments.
• Excellent verbal and written communication, including the ability to explain complex topics to technical and non‑technical audiences.
• Strong emotional intelligence: the ability to read customer sentiment and adjust your communication to fit.

Preferred Skills

• Prior experience with NIST SP 800‑171, CMMC or other compliance frameworks.
• Ability to manage multiple customer accounts and onboarding projects at the same time.
• Familiarity with CRM platforms (e.g., HubSpot) and compliance documentation tools.
• Experience working to SLAs for customer satisfaction, initial response time and resolution time.

What We Offer

• A clear path into Cybersecurity Engineering, GRC or IT Project Management
• Stock options
• Lunch provided three days a week
• Housing incentive for employees who live close to our San Francisco office
