## 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.

Senior Product Manager, Endpoint Halcyon | Product | Remote, United States | Travel: 30–40%

## About Halcyon

Halcyon builds an advanced anti-ransomware platform that enterprise security teams rely on to stop attacks other tools miss. Our agent runs on our customers endpoints, in production, in some of the largest environments in the world. We move quickly and give people real ownership, which only works because we're deliberate about who we bring on

## The Role

We are hiring a Senior Product Manager to own our endpoint product area. You will own a meaningful piece of the business: shaping strategy for your area, driving it from problem definition through GA and iteration, and being accountable for the results. You will have a strong voice in where the endpoint product goes, and you will own the tradeoffs that get it there.

Our engineering team is highly technical, and you will work with them daily. Engineering owns the solution design, but you will own the customer outcomes and business objectives. You need to hold your own in those conversations, ask the right questions, and understand why endpoint is its own discipline.

This is a customer-facing role. You will spend real time with enterprise security teams in roadmap reviews, executive briefings, and technical deep dives. You will also work closely with our Sales Architects, Customer Success, Marketing, and Support, who are in front of customers every day and are one of your best sources of signal. Understanding your audience will be key success factor, and you will need to know when to lean into technical aspects but also be able to articulate the value that the technical solutions provide to executive level buyers.

What You'll Own: The endpoint product area

- Shape the strategy for our endpoint solution and translate company objectives into a roadmap you can defend.
- Define scope, sequence the work, and make the tradeoff calls. Own them when they are questioned and adjust when needed.
- Drive initiatives from discovery through general availability and post-launch iteration through a transparent and collaborative approach.
- Report on outcomes: adoption, retention, deal impact. Shipping is not the finish line.

Customer engagement

- Meet directly with enterprise customers and prospects to validate problems before you commit to solutions.
- Represent the product in roadmap reviews, executive briefings, and technical deep dives with security teams.
- Turn scattered feedback into a defensible point of view, not a wish list.

Cross-functional execution

- Partner with engineering on requirements, architecture discussions, and delivery quality while balancing business priorities.
- Work day to day with our Sales Architects on deal support, technical objections, and what they are hearing in the field.
- Partner with Marketing, Customer Success, and Support so launches land and get adopted.
- Work within Product / UX to ensure aligned prioritization and execution.
- Surface risk early and drive it to resolution instead of reporting it.

Who We're Looking For: Required

- 5+ years in product management, with several of those years at a senior or lead level owning an area rather than a queue of assigned features.
- Endpoint experience. You have shipped agent-based software that runs on customer machines and you understand the nuances: deployment at scale, performance footprint, OS behavior, telemetry, upgrade and rollback, and what breaks in production.
- B2B enterprise products sold to external customers, in a customer-facing capacity. Not internal tools or platform operations.
- Technical aptitude to work with a highly technical engineering team. You can follow a design discussion, read an architecture doc, ask the right questions, and push back credibly.
- Engineering owns the solution; you must keep up with them and question when necessary.
- A track record you can walk through in detail: what you owned, what you decided, what shipped,and how you it drove business impact.
- Strong written and verbal communication with both engineers and executives.
- Willingness to travel to customers, roughly 30 to 40%, often in concentrated stretches.

## Preferred

- Endpoint security or endpoint management background (EDR, EPP, anti-ransomware, systems management) at a vendor where the agent was the product.
- Startup or high-growth environment experience.
- Applied AI or ML in a shipped product.

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.
- Flexible PTO policy.
- Parental leave.
- Generous equity offerings.

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

The expected base salary range for this position is $180,000 - $240,000. Compensation varies based on a variety of factors which include (but are not limited to) role level, skills and competencies, qualifications, knowledge, location, and experience. In addition to base pay, certain roles are eligible to participate in our bonus or commission plans, as well as our benefits offers, and equity awards. 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.
