Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.
About the Role
We're seeking an experienced Technical Program Manager to own and evolve our engineering operations infrastructure. This role combines hands-on operational leadership with strategic program management, requiring someone who can manage critical support operations while driving high-impact cross-functional initiatives that enhance our engineering organization's effectiveness.
Primary Responsibility: On-Call & Engineering Support Operations
You'll own the operational backbone of our engineering support systems with clear accountability and continuous improvement:
On-Call Program Management
Design and operate the on-call framework: Establish and maintain staffing models, escalation procedures, and notification systems to ensure continuous engineering coverage for critical product issues
Manage daily operations: Oversee on-call handovers, lead daily standups with assigned personnel, update customer-facing status pages where relevant, facilitate weekly handoff meetings, and ensure smooth transitions between rotations
Central dispatch function: Act as the coordination hub for support requests and incident response, providing oversight and task prioritization for on-call engineers while adjusting work priorities based on SLA constraints
Ensure equitable workload distribution: Monitor that low-priority tickets receive attention even when high-severity issues dominate, preventing backlog accumulation
Incident Response & Management
Serve as Incident Commander for incidents during North American business hours:
Alert and direct on-call staff during active incidents
Coordinate real-time response efforts and ensure appropriate resources are engaged
Update customer-facing status pages (status.horizon3.ai) throughout incidents
Notify key business stakeholders of incident status and resolution progress
Drive postmortem excellence: Lead postmortem meetings, lead the development of RCA (Root Cause Analysis) documentation, and most importantly, track and drive completion of follow-up action items to prevent recurring issues
Stakeholder Management
Cross-functional collaboration: Partner with leaders and contributors across engineering and support organizations to ensure timely resolution of product issues with significant customer and partner impact
Collaborate with delivery staff, peers, and management to identify and implement program improvements over time
Enhance quantifiable metrics to assess the effectiveness of on-call. Collaborate to collect and report on these metrics.
Identify routine requests and collaborate with on-call engineers to develop/refine TTPs and playbooks. Identify opportunities for improving technical support self-service capabilities.
Monthly governance: Lead monthly review meetings with key stakeholders to assess program health, review metrics, and identify improvement opportunities
Visibility and transparency: Maintain dashboards and tracking systems that give engineering leadership clear insight into on-call health, incident trends, support metrics, and SLA performance
Secondary Responsibility: Quarterly Strategic Initiatives
Beyond core operations, you'll program manage 1-2 cross-functional initiatives each quarter aligned with business objectives and engineering priorities. These may include infrastructure improvements, tooling rollouts, process transformations, or other strategic product engineering efforts.
