Security Data Architect

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 building the most resilient anti-ransomware platform on the market – and data is at the heart of everything we do. We’re looking for a hands-on data expert to join our Quantitative Analysis (Data) team.  

In this highly exploratory role, you'll dive into massive datasets across EDR, behavioral signals, malware telemetry, and network traffic to uncover insights, prototype decision-making systems, and directly shape our product’s defenses. 

This isn’t a rigid pipeline or BI dashboard role. You’ll have the independence to explore new ideas, run your own POCs, and drive real-world impact. If you have strong big data skills, curiosity about security, and enjoy connecting the dots between data and strategy, then this role is for you. 

Responsibilities:

• Ingest, clean, correlate, and analyze large-scale security datasets from endpoints, networks, and behavioral sources 

• Prototype and test analytics that drive detection, classification, or prevention decisions 

• Collaborate with security researchers, engineers, and product teams to integrate findings into the product 

• Explore new data sources and define what should be collected to increase intelligence value 

• Work across batch and streaming data pipelines to support both long-term analysis and near-real-time signals 

• Build dashboards or visualizations to communicate insights (internally or externally) 

Required Skills and Qualifications:

• Strong background in big data analytics, content research, or data science, ideally with 7+ years of experience 

• Proficiency in Python, SQL, and distributed data tools (e.g., Spark, Databricks, etc.) 

• Experience working with large, noisy datasets and turning them into actionable insights 

• Comfort with both batch and streaming pipelines 

• Curiosity about cybersecurity (malware, EDR, threats, etc.). No deep expertise required, but a willingness to learn is critical 

• Great communication skills and a proactive mindset. You’ll have autonomy, but also need to collaborate across functions 

Bonus Skills and Qualifications:

• Strong background in big data analytics, content research, or data science, ideally with 7+ years of experience

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: $180,000 - $280,000

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.
