Job description

About Us

At Arkenstone Defense, we empower defense tech startups with the tools, infrastructure, and compliance solutions they need to become successful prime contractors. Our mission is to remove barriers and help innovators grow - from day one to becoming a trusted prime for the U.S. Government.

We're early, we're lean, and we're building something that actually matters. The people who do well here aren't waiting to be told what to do; they see a gap and fill it.

Overview

We are seeking a highly motivated Systems Reliability Engineer (SRE) to lead the design and implementation of operational excellence across our multi-cloud environments. This role is central to ensuring the scalability, reliability, and performance of our products running in AWS, Azure, and GCP infrastructure.

As the lead SRE, you will own the uptime, observability, and system resilience for our critical services. This includes driving architecture decisions, automation practices, and incident response strategies—working closely with the product owner(s), developer teams, and security operations teams.

What You’ll Do

• Design, implement, and own the infrastructure reliability strategy across AWS, Azure, and GCP
• Champion observability by developing and maintaining effective logging, monitoring, and alerting systems
• Define and enforce SLOs/SLAs for critical systems and services
• Lead efforts in performance tuning, system hardening, capacity planning, and disaster recovery
• Own the incident management lifecycle: from detection to postmortem and root cause analysis
• Automate deployment, scaling, and recovery workflows to reduce manual toil
• Contribute to infrastructure as code (Terraform, ARM templates, CloudFormation, etc.)
• Act as a mentor and technical leader to junior engineers and cross-functional partners
• Drive a culture of accountability, ownership, and continuous improvement
• Perform any other related duties as required or assigned.

Requirements

• 5+ years of experience in SRE, DevOps, or infrastructure engineering roles
• Proven track record of operating large-scale systems in multi-cloud environments, with hands-on expertise in AWS and GCP
• Strong knowledge of cloud-native architecture, container orchestration with Kubernetes, and CI/CD pipelines
• Proficient in scripting (Python, Bash, etc.) and infrastructure automation tools (e.g., Terraform)
• Experience with monitoring and observability platforms (e.g., Prometheus, Grafana, Datadog, ELK)
• Excellent problem-solving skills with the ability to manage incidents and make sound decisions under pressure
• Clear communicator capable of translating technical concepts to mixed audiences and participating in customer discussions

Who You Are

• The Security Builder: You don't just consume security tools — you extend and improve them. You're energized by the opportunity to make analysts faster and compliance more automated.
• Quality Over Speed: You write code that lasts. You push for clean interfaces, good documentation, and tests — even in a fast-moving environment.
• Security-Minded Developer: You treat security as a first-class requirement, not an afterthought. You're comfortable reading CVEs, threat models, and compliance controls.
• Cross-Functional Partner: You can work fluidly with security analysts, engineers, and compliance professionals, translating needs into reliable software.

Mission Alignment

We are a Defense-focused company supporting sensitive and cleared workforces. The Site Reliability Engineer (SRE) - SecOps will embrace our commitment to operational excellence, compliance rigor, and a world-class employee experience.

Physical Requirements

• Prolonged periods of sitting at a desk and working on a computer
