Senior 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 Senior Infrastructure Engineer to help design, improve, and operate the secure infrastructure behind Lastwall’s identity platform. This is a senior technical individual contributor role for someone who can lead complex infrastructure work, make sound architectural decisions, and raise the reliability, security, and operability of systems that support high‑trust customers.

As an AWS Gov Cloud organization, Lastwall uses infrastructure as code to manage distributed systems with a focus on security, reliability, automation, auditability, and compliance. You will play a key role in our next wave of infrastructure improvements, helping shape the architecture, tooling, and operational practices that support mission‑critical identity services.

You will join a small, high‑impact infrastructure and platform team where technical judgment, ownership, and secure engineering practices matter. You will not be expected to manage people, but you will be expected to lead technically: setting standards, mentoring peers, guiding tradeoffs, and bringing structure to complex infrastructure challenges.

Headquartered in Fredericton, New Brunswick, and with offices in Vancouver and Honolulu, Lastwall is positioned to help strengthen North American cyber resilience.

• Senior Infrastructure Ownership
• Own complex infrastructure initiatives from design through implementation, documentation, deployment, and operational handoff. Help improve the architecture and reliability of Lastwall’s FedRAMP‑aligned infrastructure across AWS Gov Cloud and related environments.
• Design and improve secure, scalable, distributed cloud systems that support Lastwall’s identity platform. Contribute to platform engineering efforts that make infrastructure easier to operate, easier to observe, and easier for product engineering teams to build against.
• Infrastructure as Code & Automation
• Develop, maintain, and improve infrastructure as code using tools such as AWS CDK and Terraform. Deepen Lastwall’s use of automation to make provisioning, configuration, deployment, compliance support, and operational workflows repeatable, auditable, and secure.
• Lead improvements to 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 service visibility, reduce operational risk, and strengthen production readiness.
• Secure & Compliance‑Driven Operations
• Apply secure infrastructure practices across networking, access control, secrets management, containerized workloads, system hardening, operational automation, and production change management. Support infrastructure practices aligned with FedRAMP, NIST 800‑series controls, Gov Cloud deployments, and FIPS 140‑2 expectations.
• Improve deployment tooling and CI/CD pipelines that support secure, reliable software delivery. Partner with product engineering teams to improve test, deployment, and release workflows while maintaining strong security and compliance expectations.
• Incident Response & Operational Leadership
• Play a senior role in incident response, troubleshooting, and operational remediation. Help lead Learning From Incidents practices so that reliability, security, and operational maturity improve over time.
• Technical Influence & Mentorship
• Provide technical guidance to infrastructure and product engineering peers. Help set standards for architecture, automation, observability, documentation, security, and operational excellence without carrying formal people‑management responsibility.
• Technical Research & Tradeoff Analysis
• Evaluate new tools,…
