Lead Infrastructure Engineer

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 a Lead Infrastructure Engineer to help design, operate, and scale the infrastructure that supports Lastwall’s secure identity platform. This is a senior technical leadership role for someone who can own production systems, improve reliability and security, and help mature the infrastructure practices behind mission‑critical software.

You will work across cloud infrastructure, deployment automation, observability, reliability, security, and compliance‑driven operations.

The right candidate will be comfortable operating in high‑trust environments where uptime, auditability, resilience, and secure execution matter.

You will join a small, high‑impact engineering team where technical judgment, ownership, and practical leadership are essential. 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.
