Original job description

Get to Know Us

Horizon3.ai 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

We are hiring a Senior Software Engineer to join our team and help build product experiences that enable customers to understand, prioritize, and act on risk in their environments. This role is for a strong senior engineer who can own meaningful product work end-to-end, partnering closely with Product, Design, and peer engineers to deliver outstanding customer experiences.

The right candidate will be comfortable moving between backend services and modern frontend application development. This role will be approximately 80% backend focused and 20% frontend focused. You should be able to scope and drive work independently, proactively identify risks and tradeoffs, and help raise the bar for the engineers through strong execution, code reviews, and collaborative problem solving.

What You’ll Be Responsible For

Building and shipping world-class product capabilities spanning backend services, APIs, and modern web application stacks.
Own moderate-to-large projects end-to-end, including scoping, technical design, implementation, rollout, and iteration.
Help implement user-facing experiences that are clear, maintainable, performant, and aligned with product requirements and design direction.
Partner closely with Product, Design, and adjacent engineering teams to deliver cross-functional initiatives.
Proactively identify and resolve technical risks, blockers, and mis-scoped work before they become larger delivery issues.
Communicate technical topics clearly to both technical and non-technical audiences, including tradeoffs, delivery risks, and implementation choices.
Contribute to architectural and design discussions with a strong sense for maintainability, operability, and long-term team productivity.
Write high-quality code, tests, and technical documentation, and provide strong code reviews that improve the team’s overall output.
Support and mentor less experienced engineers through thoughtful feedback, onboarding support, and day-to-day collaboration.
Help improve engineering quality, team execution, and the product experience through a strong sense of ownership and continuous improvement.

What You’ll Bring

Strong professional experience building and operating production software across the full stack of application development.
Ability to independently drive substantial work from requirements gathering through delivery, while coordinating effectively with cross-functional stakeholders.
Strong written and verbal communication skills, including the ability to explain technical decisions and tradeoffs clearly.
A track record of strong engineering execution, sound technical judgment, and pragmatic problem solving under ambiguity.
Product-minded thinking and a focus on building experiences that improve customer outcomes.
Comfort working across multiple workstreams and balancing competing priorities with clarity and ownership.

Required Education/ Experience

Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
6+ years of professional software engineering experience.
Experience building distributed backend services using at least one modern language, such as Python, Go, Rust, Java, TypeScript, or similar.
Experience building backend services on a cloud platform (AWS, GCP, or Azure), and familiarity with Docker and containerized applications.
Designing and operating APIs, services, and asynchronous or event-driven systems.
Experience working with SQL base relational databases in production.
Data modeling and persistence layers for product-grade backend systems.
Observability, reliability, and operational best practices for production services.
Frontend development using modern JavaScript/TypeScript in frameworks such as React, Angular, or similar.

Preferred Education/ Experience

You don’t need all of these, but experience in some of the following will help you be successful quickly:

Experience with PostgreSQL and performance tuning for large datasets.
Experience with graph databases such as Neo4j or interest in learning them.
Experience building or consuming GraphQL backends.
Experience with ETL pipelines and data processing tools (e.g., Airflow-like frameworks, custom ETL jobs, or similar).
Experience building products or platforms in vulnerability management, exposure management, security telemetry, or related cybersecurity domains
Experience with scoring or recommendation algorithms and data-intensive products
Experience partnering closely with product managers to define and sequence an MVP without painting the team into a corner.
A track record of shaping technical direction more broadly across an organization, with influence extending beyond a single team or domain.

Travel Required

We are a fully remote company, and this job may require up to 10% of travel to be successful. We meet as a team for project kicks offs and as a company annually. These in-person meetings are crucial to building a product, team, and culture we all can be proud of.
