Role Description 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 GovCloud 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. Qualifications - 7+ years of industry experience in cloud-native infrastructure, platform engineering, DevOps, SRE, or systems engineering, ideally in SaaS, cybersecurity, identity, government technology, or other complex software environments. - Bachelor’s degree in Computer Science or equivalent practical experience. - U.S. citizenship or dual U.S./Canadian citizenship, due to the nature of the environments and customers supported by this role. - Strong experience designing, building, and operating secure, scalable, distributed cloud systems in production. - Deep experience with infrastructure as code, ideally including AWS CDK and Terraform. - Working knowledge of EC2, Docker, Kubernetes, and containerized workloads. - Strong understanding of TCP/IP networking, cloud networking, segmentation, access control, and secure system design. - Experience designing and maintaining CI/CD pipelines, including tools such as GitLab, CodeCommit, or CodeDeploy. - Strong experience with observability, monitoring, logging, tracing, and alerting, including tools such as CloudWatch, OpenTelemetry, or Prometheus. - Experience with relational databases and managed database services, including PostgreSQL, RDS, or Aurora. - Strong incident response and troubleshooting experience, ideally in high-reliability, critical, or life-and-safety-sensitive environments. - Excellent coding and scripting skills, with familiarity or ability to quickly ramp in tools and languages such as Node.js, TypeScript, Bash, GraphQL, or Rust. - Demonstrated ability to lead technical initiatives independently, influence peers, and bring structure to ambiguous infrastructure problems. - Comfort in a small but growing company, where ownership, adaptability, and practical execution matter. Requirements - 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 GovCloud 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, observe, and build against. - Develop, maintain, and improve infrastructure as code using tools such as AWS CDK and Terraform. - Lead improvements to monitoring, logging, metrics, tracing, and alerting across distributed systems. - Apply secure infrastructure practices across networking, access control, secrets management, and operational automation. - Improve deployment tooling and CI/CD pipelines that support secure, reliable software delivery. - Play a senior role in incident response, troubleshooting, and operational remediation. - Provide technical guidance to infrastructure and product engineering peers. - Evaluate new tools, architectural patterns, and infrastructure approaches. Benefits - Competitive compensation package aligned with the scope and impact of the role. - Opportunity to join after the product, customers, and proof points are real—but before the next stage of scale is fully built. - Building a people-first, security-always culture where strong contributors can have meaningful impact as the company grows.
