Job description

Responsibilities

• Lives by the NuHarbor corporate values: Help Clients Win, Always Improve, Protect the House.
• Owns the systems engineering that keeps NuHarbor's co-managed platforms running correctly; architecture, configuration, performance, and maintenance to NuHarbor and vendor best practice, so that Detection Engineering and SOC Operations can function reliably on top of them.
• Ensures client data is properly onboarded, parsed, and normalized to the appropriate data model for each platform (e.g., Splunk CIM, Microsoft ASIM, Google UDM).
• Diagnoses and resolves complex architectural problems across managed environments, including those that block or degrade downstream detection and analysis.
• Self-assigns and drives the most complex and highest-impact work, operating independently without requiring direction.
• Drives the engineering ticket queue with quality, efficiency, and completeness, resolving issues fully rather than partially.
• Designs, implements, and maintains engineering solutions for multi-tenant scalability, repeatability, and standardization across NuHarbor's client base, solving problems in a way that is durable and portable rather than one environment at a time.
• Communicates with clients at an expert technical level, building the trust and delivery excellence that turns clients into raving fans.
• Performs the engineering and architecture work required to onboard new managed services clients and to sustain and mature existing ones.
• Supports, deploys, and manages the components of NuHarbor's security automation and case management platform(s), including integrations across the managed stack (SIEM, EDR, identity, ticketing), configuration to best practice, and multi-tenancy.
• Builds and maintains automation workflows and integrations that connect the platform to client environments, partnering with SOC and Detection Engineering on the response logic those workflows execute.
• Regularly meets with clients to drive objectives forward and proactively addresses issues before they escalated.
• Develops engineering recommendations and enhancements that improve the security posture and effectiveness of each client's managed platforms, and communicates them to client stakeholders.
• Provides technical direction, leadership, and mentorship that measurably raises the capability of the broader engineering team.
• Provides architectural review and oversight for client operational projects.
• Develops and improves onboarding and operational processes, and builds processes to support new technologies at the direction of Engineering Leadership.
• Helps design the engineering approach and operational processes for newly adopted technologies, in support of new and evolving service offerings.
• Maintains the industry and vendor certifications required to support the managed services catalog, and ensures managed platforms are patched and hardened in response to relevant vulnerabilities.
• Participates in a 24x7 on-call rotation; other duties as assigned by Engineering Leadership.
