Job summary

Horizon3 is hiring a Staff Software Engineer, Backend to anchor the technical direction of the Assessment Experience team and transform how customers use NodeZero to secure environments. You will design and build backend services, APIs, and data models powering an outcome-based experience.

This hands-on role requires writing production code, setting design and operational standards, and mentoring engineers across the organization while shaping architecture and driving cross-team initiatives in a

Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
• 8+ years of professional software engineering experience, including sustained ownership of production backend systems.
• Experience building backend services in at least one modern language, such as Python, Go, Rust, or TypeScript.
• Strong SQL skills and production experience with at least one relational database, including complex joins, CTEs, window functions, and deliberate schema design.
• Experience building backend services on a cloud platform (AWS, GCP, or Azure) and familiarity with Docker and containerized applications.
• Experience designing and operating APIs, services, and asynchronous or event-driven systems.
• Experience with data modeling and persistence layers for product-grade backend systems.
• Operational maturity: observability, testing, reliability practices, and a record of debugging difficult, customer-visible production problems.
• Technical design documents, architectural proposals, or engineering standards that other teams have adopted.
• A record of leading cross-team technical work and mentoring engineers.

Responsibilities

• Own the technical direction for Assessment Experience backend systems, from initial concept through implementation, iteration, and long-term evolution.
• Design and build scalable backend services, APIs, and asynchronous or event-driven workflows that let customers configure assessments and consume their results reliably.
• Lead architectural decisions that balance velocity, reliability, data correctness, maintainability, extensibility, and operability, and document the reasoning so others can build on it.
• Translate ambiguous product and customer goals into concrete technical strategy, architecture, and execution plans, working closely with Product, Design, and engineering leadership.
• Drive problems that cross team boundaries, partnering with teams that own attack content, integrations, and asset matching to define clean interfaces and remove systemic blockers.
• Contribute production code and set the standard for design quality, code quality, testing, observability, and safe rollout practices such as feature flags.
• Identify risks, dependencies, and tradeoffs early, and help the team sequence work across multiple concurrent initiatives, and evaluate emerging technologies, including AI-driven approaches to outcome-based, conversational experiences, recommending adoption or avoidance with clear rationale.
• Raise the technical bar through design reviews, code reviews, architecture proposals, and technical writing that other teams can adopt as standards.
• Mentor P3 and P4 engineers through thoughtful feedback, technical coaching, and frameworks that help them do the best work of their careers.
• Communicate complex technical concepts clearly to both technical and non-technical audiences, including leadership stakeholders.
• Support hiring by helping attract, interview, and calibrate strong engineering talent.
• Use customer feedback and production signals to improve how safely, clearly, and naturally customers work with NodeZero to identify real risk and act on the results.
