Employer job description

Get to Know Us
Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments.
NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs.
We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants.

What You’ll Do
- As a Senior Backend Engineer on the Security Controls team, you'll drive the technical vision for EDR telemetry and detection inside NodeZero, with direct influence over how EDR effectiveness and tuning evolves as a core product capability. Modern endpoints are instrumented by CrowdStrike, SentinelOne, Microsoft Defender, Carbon Black, and others. Our customers need to know, with evidence, which of our attack techniques their EDR caught, which ones slipped through, and why. Answering that at scale — across platforms, tenants, and operator objectives — requires someone who deeply understands the telemetry surface and can turn that understanding into a product. Over time, this role will own the technical work for incorporating AI and ML research into how we reason about detection gaps, generate tuning recommendations, and scale effectiveness insights.
Responsibilities
- Develop core product features in ETL (Extract, Transform, Load) and GraphQL to support data processing and retrieval.
- Design and implement backend APIs in GraphQL to facilitate data interactions between different components of the product.
- Build and maintain ETL pipelines for efficient data processing and analytics.
- Collaborate with frontend team members to present data in a clear and user-friendly format, enhancing the product's user experience.

- Ability to own and manage concurrent initiatives, demonstrating effective judgment in prioritization and time management.
- Driven, self-managed, capable of conceiving and implementing solutions on your own and with a team
- A strong desire to continuously improve and learn new technologies in a fast-paced Agile development environment
- Excellent analytical and problem-solving skills, effective communication, attention to detail and high-quality work
- Strong technical documentation ability to support the development process.
- Effective communication and collaboration with designers, developers, and product managers.
- Ability and interest in mentoring junior and mid-level engineers to foster their growth and development.
- Required Education / Experience
- Bachelor's Degree in Computer Science, Computer Engineering or related field.
- 7+ yrs professional software engineering experience using modern object-oriented or functional languages (Python, Java, Go, Scala, C++, TypeScript, etc).
- Experience building applications on cloud computing platforms such as AWS, Azure, GCP, using container technologies such as Docker and Kubernetes.
- Expert proficiency in SQL.
What Sets You Apart
Deep familiarity with at least one major EDR platform (CrowdStrike, SentinelOne, Microsoft Defender) at the telemetry and API level.
Understands detection logic, alert triage workflows, and how SOC teams consume EDR output.
Expert proficiency in SQL and experience with various database architectures including relational (PostgreSQL) and graph (Neo4j).
Experience building GraphQL backends.
