What we do:
Halcyon is the industry’s first dedicated, adaptive security platform that combines multiple proprietary advanced prevention engines along with AI models focused specifically on stopping ransomware.

Who we are:
Halcyon was formed in 2021 by a team of cyber industry veterans after battling the scourge of ransomware (and advanced threats) for years at some of the largest global security vendors. Comprised of leaders from Cylance (now Blackberry), Accuvant (now Optiv), Fireye and ISS X-Force (now IBM), Halcyon is focused on building products and solutions for mid-market and enterprise customers.

As a remote-native, completely distributed global team, we recognize great talent can exist anywhere. We invite you to apply to a job you’re interested in and we'll work a plan to meet your needs.

The Role:

Halcyon’s goal is to deliver an anti-ransomware solution that breaks new ground in what a security product can achieve. Aligned with this vision, we are seeking an experienced engineer to contribute to the development of our macOS agent.

  • Cross-Platform Code Contribution: Work with multi-platform logic in Rust for a user-level service alongside macOS-specific code.

  • Debugging Optimization: Use logs, debuggers, and profiling tools to analyze performance and correct behavior.

  • Test Maintain Code Quality: Write unit and integration tests, adhering to consistent coding style and architecture.

  • Team Collaboration: Communicate effectively across teams to ensure interoperability with other components and alignment with architectural goals.

Skills and Qualifications:

  • Ability to develop high-quality code in Swift and C++

  • Experience with macOS extensions in an endpoint security product (e.g., EndpointSecurity, NetworkExtensions)

  • Experience developing and shipping production software for macOS

  • 401k plan with a generous employer contribution.

  • Short and long-term disability coverage, basic life and ADD insurance plans.

  • Medical and dependent care FSA options.

  • Flexible PTO policy.

Base Salary Range: $180,000 - $240,000

Bonus Range: 10%

In accordance with applicable state and federal laws, the range provided is Halcyon’s reasonable estimate of the base compensation for this role. The actual amount may differ based on non-discriminatory factors such as experience, knowledge, skills, abilities, and location. Base pay is one part of the total package that is provided to compensate and recognize employees for their work, and this role may be eligible for additional discretionary bonuses/incentives, and equity in the Company.

We understand it takes a diverse team of highly intelligent, passionate, curious, and creative people to develop the exceptional product we are building. Our dynamic team has incredible perspectives to share, just as we know you do, and we take great pride in being an equal opportunity employer.

Threats like ransomware are designed to evade modern security tools, and just one miss can have a catastrophic impact on your organization. Halcyon is the first Anti-Ransomware and Cyber Resilience Platform with automated encryption key capture and autonomous decryption capabilities to keep your operations running 24/7/365.

Most security vendors are quick to update their solutions once a threat is seen in the real world. But what if you are one of the first victims? Without a dedicated anti-ransomware engine, the protection gap can range from 24 hours to several days or even weeks. Traditional rules-based EDR and other endpoint protection products rely on convolutional neural network AI models for detection that are generally too complex to quickly train on emerging threats. In contrast, Halcyon leverages Capsule Networks (CapsNets) AI micro-models that allow us to rapidly train, test and deploy new protection mechanisms to address novel and emerging threats exponentially faster than traditional endpoint tools.

After gaining initial access to a system, attackers will routinely target security tools active on an endpoint. Bypassing and unhooking these products has a lower resource cost than attempting to sneak malicious binaries or scripts past automated detection tools. With countless real-world bypasses published, it is clear that security products also need to be hardened against attacks. The Halcyon agent specifically prevents leading endpoint tools from being disabled, bypassed or unhooked.

Ransomware events can seriously disrupt business operations, that is why our resilience engine was designed to recover infected systems as quickly as possible. Once a ransomware incident occurs, the remediation clock starts ticking. While Halcyon delivers the most advanced detection and prevention capabilities in the market, we also provide the only automated resilience layer to assure a ransomware attack never slips by your defenses. Halcyon is enabled with automated encryption key capture and autonomous decryption capabilities that immediately decrypt any infected devices.
