Job Description

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 is redefining what security software can do, with a focus on anti-ransomware innovation. We're looking for an Engineering Manager to lead a 6-10 person cross-platform endpoint development team—delivering next-gen protection for Windows, Linux, and macOS.

Responsibilities:

  • Manage a cross platform Rust development team building for Windows, Linux and macOS

  • Nurture a collaborative, high-performing team culture

  • Work with development and research teams to plan, design and deliver features

  • Offer input on future direction and strategy of the Halcyon endpoint

  • Estimate and track team progress

  • Be active in the code review process

  • Mentor young engineers and future leaders

  • Develop deep product expertise to guide technical direction and unblock your team

  • Partner with the sustaining team to resolve customer issues promptly

  • Coordinate the agent release schedule

Skills and Qualifications:

  • Experience leading a high-performing engineering team

  • Experience working in a fully remote environment

  • Ability to balance strategic leadership with day-to-day team management

  • Experience in developing commercial or enterprise software in C++ and/or Rust

  • Proficient with Windows, macOS and Linux

  • Strong written and verbal communication skills

  • Bonus points for experience with enterprise endpoint software, Jenkins, or Python

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: $210,000 - 260,000

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.

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
