Lastwall

About The Position

Lastwall is a Canadian cybersecurity company focused on identity and mission-critical operations across defense, government, and critical infrastructure. Trusted by the U.S. Department of Defense and the Government of Canada, Lastwall has spent nearly a decade securing sensitive government environments. With FedRAMP Moderate Authorization, proven traction in the U.S. federal market, and growing demand for sovereign cybersecurity capability, we are entering a defining growth phase across Canada and the United States. We are hiring an Infrastructure Engineer to help operate, improve, and scale the secure infrastructure behind Lastwall’s identity platform. This is a hands-on engineering role for someone who can work across cloud infrastructure, platform engineering, automation, observability, and incident response in high-trust, compliance-driven environments. As an AWS GovCloud organization, Lastwall uses infrastructure as code to manage distributed systems with a focus on security, reliability, automation, and compliance. You will contribute to the continuous improvement of infrastructure that supports demanding defense, government, and critical infrastructure customers, including environments where reliability and performance matter for mission-critical use cases. You will join a small, high-impact infrastructure and platform team where strong technical judgment, operational discipline, and secure engineering practices matter. You will help improve the systems, tools, and workflows that allow Lastwall to deliver resilient software at scale. Headquartered in Fredericton, New Brunswick, and with offices in Vancouver and Honolulu, Lastwall is positioned to help strengthen North American cyber resilience.
