  • Communicate key findings from data, enabling customers to better understand security threats and mitigate risks.

Qualifications:

  • Bachelor's degree in Computer Science, Data Science, Engineering, or other technical discipline (or equivalent professional experience).
  • 5+ years of experience in machine learning, NLP, or data science roles.
  • Strong proficiency in Python, Go, and machine learning libraries such as TensorFlow or PyTorch.
  • Experience with data processing frameworks like Kafka, Spark, and real-time data streaming technologies.
  • Deep understanding of model training, feature engineering, and performance optimization.
  • Experience working with cloud platforms (AWS, GCP, etc.) and containerization (Docker, Kubernetes).
  • Expertise in large-scale data analysis, with experience in anomaly detection and predictive modeling.
  • Ability to transform complex datasets into understandable, actionable insights for end-users.

Preferred Qualifications:

  • Experience working with security datasets or in the cybersecurity domain.
  • Familiarity with GCP VertexAI and Google BigQuery.
  • Proven ability to integrate machine learning models in SaaS products and customer-facing platforms.
  • Strong communication skills and ability to collaborate with technical and non-technical stakeholders.

 

Our target salary range for this role is between $134,000 USD and $220,000 USD + bonus eligibility and equity.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
