About the role

About Lastwall
We are a cybersecurity company with offices in the United States and Canada, specializing in the development and delivery of highly secure, identity-centric, and quantum-resilient cybersecurity solutions. We aim to build innovative, security-first technologies designed for compliance-driven and threat-intensive environments such as those found in defense, government, and critical infrastructure sectors.
Our solutions are engineered with a security-first approach, leveraging cutting-edge advancements in identity and digital defense to outpace threat actors and protect sensitive systems from evolving cyber threats. By focusing on inhibiting the efficacy of adversaries and exponentially bolstering client security, we provide essential tools to safeguard operations in some of the most mission-critical industries.
If you’re a US or Canadian Citizen who is passionate about working at the forefront of cybersecurity technology in environments that demand unparalleled security and reliability, we’d love to have you join our team!
The Opportunity
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.
