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 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 Gov Cloud 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.

• Operate and improve Lastwall’s FedRAMP‑aligned infrastructure across AWS Gov Cloud and related environments. Build and maintain secure, scalable, and reliable cloud systems that support mission‑critical identity services.
• Infrastructure as Code & Automation
• Develop, maintain, and improve infrastructure as code using tools such as AWS CDK and Terraform. Help deepen Lastwall’s use of automation to make infrastructure provisioning, configuration, deployment, and operations repeatable, auditable, and secure.
• Contribute to Lastwall’s platform engineering efforts by improving the systems, tooling, and workflows that support product development, testing, deployment, and production operations. Help create rapid feedback loops and strong collaboration between infrastructure and product engineering.
• Improve monitoring, logging, metrics, tracing, and alerting across distributed systems. Use tools and practices such as Cloud Watch, Open Telemetry, Prometheus, and related observability technologies to improve system visibility, operational readiness, and incident response.
• CI/CD & Deployment Tooling
• Enhance and maintain deployment tooling and CI/CD pipelines to support reliable software delivery. Work with tools such as Git Lab, Code Commit, Code Deploy, Docker, and containerized workloads to improve release quality and development velocity.
• Security & Compliance‑Driven Operations
• Apply secure infrastructure practices across networking, access control, secrets management, containerized workloads, system hardening, and operational automation. Support infrastructure practices aligned with FedRAMP, NIST 800‑series controls, Gov Cloud deployments, and FIPS 140‑2 expectations.
• Incident Response & Learning from Incidents
• Participate in incident response, troubleshooting, and operational remediation. Help guide the team through Learning From Incidents practices so that reliability, security, and operational maturity improve over time.
• Technical Collaboration
• Work closely with infrastructure, product engineering, security, and compliance stakeholders to evaluate tradeoffs, improve architecture, and deliver infrastructure that meets customer, compliance, and operational needs.

• 5+ years of industry experience in cloud‑native infrastructure, platform engineering, Dev Ops, SRE, or systems engineering, ideally in SaaS, cybersecurity, identity, government technology, or other complex software environments.
