Senior Engineering Manager

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 seeking a thoughtful, experienced Senior Engineering Manager to join our team and help scale our growing engineering organization. This is a critical role focused on enabling sustainable growth, fostering engineering excellence, and supporting a high-trust, high-autonomy team culture. You'll work closely with engineers, product managers, and cross-functional stakeholders to ensure team health, reliable execution, and a strong sense of purpose and accountability.

We're looking for someone who brings a servant-leadership mindset, a mentoring orientation, and a steady hand during both calm and storm. You will report to the Director of Cloud Engineering and partner closely with peer leaders across Product, Engineering, QA, and Agile.

This role is ideal for someone who is excited to step into a hands-on leadership role where they can stay close to the team, help shape outcomes, and create lasting impact through influence rather than authority.

Responsibilities:

• Lead and support one or more Cloud Engineering teams.
• Foster a culture of psychological safety, autonomy, and accountability.
• Actively mentor engineers and emerging leaders to grow their impact and effectiveness.
• Partner with leaders across the organization to drive infrastructure strategy, CI/CD improvements, observability practices, and operational maturity.
• Collaborate closely with product, QA, and agility partners to align on priorities, delivery, and scope.
• Own operational health of your teams: on-call rotations, velocity tracking, and continuous improvement.
• Step in to unblock teams, remove organizational friction, and help create momentum.
• Maintain deep context on what your team is building and why, offering strategic perspective without micromanaging.
• Occasionally dip into the codebase to review pull requests, understand implementation details, and provide relevant technical feedback.
• Support a strong culture of engineering rigor, ensuring teams build with quality, observability, security, and performance in mind.
• Partner with engineers and technical leads to shape architectural direction and maintain high technical standards.

Skills and Qualifications:

• Experience leading multiple engineering teams, preferably in fast-paced, high-growth SaaS
• Familiarity with cloud-native architecture and DevOps practices, including AWS, Terraform, Kubernetes, and CI/CD tooling.
• Track record of creating strong team culture, high trust, and psychological safety.
• Effective coach with experience guiding engineers, peers, and upward into executive leadership.
• Solid understanding of modern software development practices, including infrastructure, observability, and reliability.
• Comfortable navigating ambiguity, scaling challenges, and cross-functional alignment.
• Excellent communicator who leads with clarity, empathy, and pragmatism.

Bonus Experience:

• Background in security, developer platforms, or data-intensive systems.
• Familiarity with Halcyon's architecture and AWS stack.
• Previous experience with compliance-heavy environments like FedRAMP.

Benefits: 

Halcyon offers the following benefits to eligible employees: 

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

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

• Medical and dependent care FSA options. 

• 401k plan with a generous employer contribution.
