Overview

Kastle is the nation’s leading provider of Managed Security Services. Our customers depend on us every day and include the who’s who of commercial real estate, distinguished global retail brands, leading commercial enterprises and critical government facilities. We are committed to providing a ‘Wow’ customer experience and we continually invest in the next big ideas to shape and transform our industry.

We are proud to say that our people are the industry’s best and we work hard to create a culture that provides a compelling career for talented individuals.

The Security Systems Solutions Architect (SSA) is a senior, customer-facing technical expert within Kastle's Product organization. The SSA leads technical discovery and solution validation on complex projects — including engagements involving new engineering, third-party products or integrations outside the Kastle product portfolio, or non-standard infrastructure — ensuring that scope is fully defined and technically sound before installation begins. The SSA is available to any project requiring deeper product or engineering expertise in customer-facing settings.

The SSA also develops the discovery standards, tools, and reference designs used across the sales and delivery organization; coaches Sales Engineers in advanced discovery; and partners with Product Management on requirements intake, alpha and beta programs, and roadmap input. The position works closely with sales, the Presales Business Manager, sales engineering, project management, and the Integrations team, and is a key contributor to reducing change orders, rework, and schedule risk on complex installations.

Responsibilities

Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

Technical Discovery & Solution Validation
  • Lead technical discovery on complex projects, with emphasis on engagements involving new product engineering, third-party products or integrations outside the Kastle product portfolio, or non-standard network environments.
  • Participate directly in customer discovery and solutioning conversations on qualifying projects, identifying technical risks, gaps, and constraints as solutions are developed.
  • Validate proposed scope for technical accuracy and completeness before contract award, including network architecture, integration requirements, infrastructure conditions, and site constraints.
  • Serve as the technical escalation point for projects that meet Kastle's complex-project criteria — and for any project where deeper product or engineering representation is requested — determining what additional discovery or validation is required.
  • Partner with the Integrations team on projects involving third-party API integrations and SDK partner deployments — leading pre-award feasibility and scoping when a solution requires products or integrations outside the Kastle product portfolio, transferring validated scope at contract award, and codifying proven integration patterns into reference designs for reuse.
  • Verify that customer network and infrastructure requirements — including firewalls, VLAN segmentation, and customer-managed environments — are documented and resolved prior to installation.
  • Support project delivery teams on complex projects through installation and commissioning, ensuring solutions are implemented as designed.
Solution Design
  • Design integrated electronic security solutions spanning access control, video surveillance, VMS, and intrusion detection for complex projects.
  • Produce solution documentation including layouts, device maps, schematics, and integration diagrams.
  • Evaluate customer legacy systems and define how existing equipment integrates with Kastle offerings.
  • Ensure all designs comply with applicable codes, standards, and customer specifications.
Discovery Standards & Tools
  • Develop and maintain the standardized discovery toolkit used on complex projects, including discovery checklists, network requirement questionnaires, reference designs, and scoping templates.
  • Continuously improve discovery standards based on field outcomes, recurring issues, and product changes.
  • Define the criteria and process for…
