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 redefines what a security product can do. We’re looking for an experienced Windows Sustaining Engineer to support both the development and long-term maintenance of our Halcyon Anti-Ransomware platform on Windows. 

Responsibilities:

  • Diagnose and triage customer issues: Analyze logs, crash dumps, and diagnostic data to identify root causes and drive timely resolutions.

  • Cross-functional collaboration: Work closely with customer support, sales teams, product management, and engineering teams to resolve customer issues, improve product quality, and ensure seamless integration across components.

  • Kernel-mode and user-mode code development: Write code that transforms messages, processes data, interfaces with components in different languages, and interacts with Web APIs.

  • Optimization and profiling: Use profiling tools to optimize code performance.

  • Test and maintain code quality: Write unit and integration tests, adhering to consistent coding styles and architectural guidelines.

Skills and Qualifications:

  • Proven ability to troubleshoot and debug complex systems effectively.

  • Proficiency with windbg in both user-mode and kernel-mode.

  • Experience identifying performance bottlenecks using Window Performance Analyzer.

  • Strong written and verbal communication skills.

  • Ability to develop high-quality code in C++.

  • Experience programming in Rust or a strong desire to learn Rust.

  • Knowledge of Windows NT internals.

Bonus Skills and Qualifications:

  • Experience with additional programming languages such as Python.

  • Familiarity with SQL.

Benefits:

 Halcyon offers the following benefits to eligible employees:

  • Comprehensive healthcare (medical, dental, and vision) with premiums paid in full for employees and dependents.

  • 401k plan with a generous employer contribution.

  • Short and long-term disability coverage, basic life and AD&D insurance plans.

  • Medical and dependent care FSA options.

  • Flexible PTO policy.

  • Parental leave.

  • Generous equity offering.

The Company reserves the right to modify or change these benefits programs at any time, with or without notice.​

Base Salary Range: $160,000-220,000

Bonus Target: 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.
