You will help strengthen the systems, practices, and infrastructure foundations that allow Lastwall to scale with demanding government, defense, and critical infrastructure customers. Headquartered in Fredericton, New Brunswick, and with offices in Vancouver and Honolulu, Lastwall is positioned to help strengthen North American cyber resilience.
