- **Work type:** onsite

## Job description

## About The Role

Artemis Security is hiring our first Security Engineer to own internal security at the company. In a cybersecurity company, internal security isn't a checkbox — it's a reflection of everything we sell. Our customers trust us with their most sensitive telemetry, and how we run our own environment has to meet a bar higher than anyone else's.

This is a hands-on, senior IC role. You'll be the technical owner of Artemis's internal security posture, building the systems, controls, and programs that protect the company from the inside out. You'll also own the security-critical parts of our IT environment, working closely with our IT provider on execution. You'll report into leadership, partner with our founders, engineering, and security teams, and have the autonomy to build the security foundation the right way from day one.

You won't be managing a team. You'll be building the program.

## Responsibilities

Security (primary focus)

- Own Artemis's internal security posture end to end, including endpoint security, identity and access management, network security, email security, and cloud security for our corporate environment
- Design and run our identity strategy across SSO, MFA, conditional access, and privileged access management
- Build and operate our vulnerability management program, including patching, endpoint hardening, and continuous monitoring
- Lead incident response for internal security events, from detection and containment through investigation and post-incident review
- Drive our compliance and certification work (SOC 2 Type II, ISO 27001, and others as we grow), including scoping, evidence collection, and working with external auditors
- Build and run the security awareness program, including ongoing training, phishing simulations, and role-specific education
- Set and maintain security policies, standards, and internal documentation that scale with the company
- Own vendor risk and third-party security reviews for tools and partners we bring in
- Partner with product security and engineering leadership to keep internal and product security aligned
- You’ll be working hands-on with the best security tool in the world, Artemis!

IT (secondary but critical)

- Own the IT architecture
- Selecting which IT provider we will use and making any changes, if necessary
- Manage the tools and configurations that keep the team productive and secure across Google Workspace, Slack, our identity provider, MDM, and related systems
- Contribute to the design and security of our office network, AV, and physical access controls

## Qualifications

- 5+ years of hands-on experience in security engineering, IT security, or corporate security, with real ownership of internal security programs at a top-tier software/tech company
- Deep expertise in one or more of the following: identity and access management, endpoint security, cloud security (AWS/GCP/Azure), or SaaS security
- Hands-on experience with SOC 2 and/or ISO 27001 audits, including scoping, evidence collection, and working with auditors
- Strong understanding of modern attacker tradecraft — you know how real breaches happen, not just what the frameworks say
- Direct experience leading incident response for internal security events, from detection through post-mortem
- Familiarity with modern security tooling across EDR, SIEM, IAM, MDM, DLP, email security, and vulnerability management
- Strong systems thinking — you can balance security rigor with the reality of a fast-moving startup
- Clear communicator who can translate security tradeoffs to leadership and non-technical teams
- Comfort operating with autonomy in an early-stage environment and building programs from scratch, without a manager or team backing you up

## Nice to Have

- Prior experience as the first or founding internal security hire at a startup
- Background as a practitioner in cybersecurity — SOC, threat detection, red team, or product security experience
- Relevant certifications (CISSP, OSCP, GCIA, GCIH, CISA, or equivalent)
- Experience with security operations tooling that Artemis itself sells (SIEM, XDR, detection & response platforms)
- Familiarity with regulated frameworks beyond SOC 2 and ISO (FedRAMP, HIPAA, PCI, GDPR)

## Compensation

We offer a competitive compensation of $180,000-$230,000 per year, and a top-of-market equity component. A variety of factors are considered when determining the compensation, including a candidate’s professional experience. Final offer amounts may vary from the amounts listed.

## Equal Opportunity

At Artemis, we believe the best ideas come from diverse teams. We’re committed to creating an inclusive environment where people of all backgrounds, experiences, and perspectives can do their best work. We welcome everyone, regardless of race, gender, age, religion, identity, or anything else that makes you, you.

## About Artemis

## Company Overview
- **One-liner**: Artemis is building an AI-native protection platform that helps security teams detect, investigate, and respond to modern cyber threats by replacing traditional SIEMs with agentic, environment-aware detection.
- **Entity Type**: Private (Series A)
- **Headquarters**: New York, New York, United States
- **Founded**: 2025
- **Founders**: Shachar Hirshberg (CEO) and Dan Shiebler (CTO)

## Core Business
- Primary industry: Cybersecurity (AI-Native Security Operations)
- Target customers: Enterprise security teams (SOC, detection engineering, threat hunting)
- Mission or purpose: Reinventing how companies defend themselves in the AI era by delivering precise, adaptive, and cost-effective threat detection and response.

## Products & Services
- **[Artemis AI-Native Protection Platform]**: A SaaS platform that continuously analyzes a customer’s technical and business environment to autonomously create, tune, and maintain detections. It correlates identity, cloud, endpoint, network, and SaaS telemetry into complete attack narratives. Features include AI agents for autonomous investigation, natural-language querying, federated telemetry (reducing ingest costs), automated threat intelligence mapping (MITRE ATT&CK), and incident response playbooks.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding of $70M (Series A of $50M and Seed of $20M, both closed in April 2026)
- **Notable Investors/Partners**: Felicis, First Round Capital, Brightmind, Theory VC, Lockstep, Two Sigma Ventures, plus a group of prominent cybersecurity operators
- **Growth Signals**: The company has grown to 22 employees in under two years (founded 2025), with a monthly headcount growth of +11.8%. It reports a 96% reduction in mean time to resolution for customers and a “2 weeks to coverage” deployment timeline. The company is actively hiring across engineering, GTM, and security roles (12 open positions as of mid-2026).

## Competitive Advantages
- **AI-Native Architecture**: Built from the ground up with AI agents that reason, adapt, and act—not a chatbot bolted onto a legacy SIEM. This allows for autonomous detection writing, investigation, and response.
- **Federated Telemetry**: Streams only detection-critical logs and retrieves the rest on demand, dramatically reducing data ingestion costs while maintaining full visibility.
- **Environment Intelligence**: Continuously builds a living model of assets, users, configurations, and business context, enabling detections that adapt to the specific environment rather than relying on generic rules.
- **Founding Team Depth**: CEO Shachar Hirshberg led product for Amazon GuardDuty and was an early employee at Demisto; CTO Dan Shiebler led AI/ML at Abnormal Security and built ML systems at Twitter.

## Strategic Focus
- Current priorities include expanding the enterprise customer base, deepening AI agent capabilities across the full security lifecycle (detection, investigation, response, containment), and scaling the go-to-market team (hiring for enterprise sales, partnerships, and product marketing).
- The company is also focused on closing the gap between traditional SIEMs and the speed of AI-driven threats, with a clear emphasis on replacing legacy detection workflows.

## Why Work Here
- **Culture & Mission**: Mission-driven work at the intersection of AI and cybersecurity, with a focus on building “AI that defends modern systems.” The team includes alumni from Amazon, Abnormal Security, Two Sigma, and Lockheed Martin.
- **Work Policy**: Most roles are based in New York City (HQ), with some remote positions (e.g., Senior Software Engineer, Infrastructure).
- **Benefits**: Top-of-market salary and equity in an early-stage company; comprehensive health, dental, and vision insurance; 401k plan; daily team meals (breakfast, lunch, dinner); $200/month commute reimbursement; $300/month wellness stipend.
- **Engineering Culture**: AI-first development approach—teams design systems where AI agents reason and act autonomously, rather than relying on handcrafted rules. Tech stack includes TypeScript, Python, React, ClickHouse, Snowflake, Terraform, and more.
- **Growth**: Early-stage company with significant growth potential and a fast-paced, high-impact environment.
