Original 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. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.

What You’ll Do

As a Staff Backend Engineer on the Admin Experience team, you’ll provide hands-on technical leadership for NodeZero’s account administration capabilities. You’ll shape how services and APIs support user access, parent-child account controls, account settings, and related capabilities such as roles, access controls, and audit logs. You’ll lead complex changes to account and authorization models, helping teams preserve secure tenant boundaries while making administration easier for customers. You’ll remain hands-on in implementation and partner across Product and Engineering to set durable technical direction and improve production readiness.

Responsibilities

Set technical direction for backend services and APIs supporting user access, account hierarchies, settings, and administration workflows.
Lead architecture and implementation of cross-cutting work involving authorization, tenant boundaries, and safe evolution of customer account models.
Remain hands-on in production code while guiding design decisions, technical tradeoffs, and delivery across the team.
Raise standards for API quality, testing, security, observability, rollout practices, and operational readiness.
Partner with Product and adjacent teams to align interfaces and keep administration capabilities consistent across NodeZero.
Mentor and influence engineers through design reviews, code reviews, pairing, and clear technical documentation.
Help diagnose complex production issues and drive improvements that prevent recurrence.

What You’ll Bring

Ability to lead through ambiguity, break down broad problems, and align multiple teams around a practical technical direction.
Strong judgment balancing security, customer experience, scalability, maintainability, and delivery speed.
Excellent communication and technical-writing skills; able to explain architecture and tradeoffs to varied audiences.
A collaborative approach to mentoring engineers and improving engineering standards beyond a single project.
Personal ownership of production quality, operational readiness, and continuous improvement.

Required Education / Experience

Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
8+ years of professional software engineering experience, including deep experience building production backend systems.
Track record of leading technical direction or architecture for complex services, APIs, or platform capabilities.
Strong experience with distributed or multi-tenant systems, data modeling, SQL, and production reliability.
Ability to influence technical decisions across teams and communicate architecture and tradeoffs clearly.
Experience mentoring engineers and improving the quality and consistency of engineering practices.

Required Tech Stack Experience

Deep experience building backend services in a modern language such as Python, Go, Java, or TypeScript.
Strong experience with SQL and relational data stores, API design (REST or GraphQL), and cloud-hosted production services.
Experience with containerized services such as Docker and with testing and operational practices for customer-facing systems.
Experience with every example technology is not required; demonstrate depth in relevant areas and the ability to guide cross-team choices.

What Sets You Apart?

Deep experience with RBAC, SSO, account hierarchies, delegated administration, auditability, or identity and access management.
Experience with PostgreSQL, AWS, Kubernetes, feature flags, and observability tools such as Datadog, Prometheus, or OpenTelemetry.
Experience in cybersecurity or a customer-facing SaaS platform with complex tenant models.

[Optional] Travel Required

We are a fully remote company, and this job may require up to 5% of travel to be successful.
