Salary: USD 260,000 - 280,000 / annual
Horizon3.ai is a fast-growing cybersecurity company building NodeZero, an autonomous penetration testing platform used by organizations of all sizes, from educational institutions to Global 100 enterprises. The platform is adopted by ITOps/SecOps teams, consulting pentesters, and Managed Service Providers (MSPs) and Managed Security Service Providers (MSSPs).
You will lead and scale the MSP/MSSP engineering team, owning platform capabilities that enable partners to deliver NodeZero as a managed service at scale. This is a hands-on leadership role where you'll drive both team growth and technical strategy.
Key responsibilities:
- Build, mentor, and grow a team of backend and full-stack engineers focused on multi-tenant platform capabilities for MSP and MSSP partners
- Drive platform strategy for MSP/MSSP use cases including multi-tenancy, parent/sub-client relationships, tenant allocation, partner administration, client management dashboards, co-branding, and white-labeling
- Establish and evolve architecture for account hierarchies, delegated administration, tenant isolation, and partner-specific entitlement and licensing flows
- Use design reviews, code reviews, and blameless retrospectives to drive engineering excellence
- Partner with Product, Customer Success, Partnerships, and Sales to align roadmap with partner needs
- Balance partner support and operational needs while executing on platform improvements and new capabilities
- Hire, onboard, mentor, coach, and develop your engineering team
- Recognize and retain high performers
- Lead horizontally with peer managers and senior leaders
The role is fully remote but may require up to 10% travel. Horizon3 has a Chicago office where some roles require regular in-office presence, but this position is remote-first.
Qualifications:
- Demonstrated experience leading engineering teams building and operating multi-tenant SaaS platforms at scale
- Strong technical background in multi-tenancy, account hierarchies, tenant isolation, delegated administration, and parent/sub-client models
- Experience with partner or channel software models (MSP, MSSP, OEM, white-label, reseller, or co-branded platforms)
- Proven track record of taking complex platform capabilities from design through production and at-scale operation
- Strong working knowledge of at least one major cloud provider (AWS, GCP, or Azure); AWS preferred
- Experience with identity and access management, RBAC, authorization models, and enterprise account structures
- Experience driving architecture decisions through structured design reviews, RFCs, or similar frameworks, particularly for multi-tenant or partner-facing systems
- Ability to write clear, durable process documentation
- Comfortable with modern backend languages such as Python or Go; able to engage meaningfully in technical discussions and code reviews
- Proven ability to hire, develop, and retain high-performing engineers in remote or distributed environments
- Strong communication skills across technical and non-technical audiences
- Demonstrated ability to balance strategic roadmap delivery against competing partner support and operational needs
Nice to haves: background in cybersecurity or security platforms; experience with third-party risk management or compliance-adjacent capabilities; familiarity with licensing, entitlements, subscription management, or billing integrations.
