DevOps Engineer, DevEx

Applicants must be authorized to work for any employer in the country in which the role is being hired. We are unable to sponsor or take over sponsorship of an employment visa at this time. Mark43’s mission is to empower communities and their governments with new technologies that improve the safety and quality of life for all. We build powerful, scalable, and elegant software that sets a new standard for the tools upon which our first responders rely. Our users are diverse, and we are therefore committed to embracing diversity of thought and experience within our team. The Mark43 law enforcement platform delivers mission-critical services to agencies across the country. When our systems are unavailable, real-world safety is impacted. As a Platform Engineer, you will take ownership of critical platform capabilities that ensure our systems are reliable, scalable, and equally important: enable engineers to build, deploy, and operate software with speed and confidence. In this role, you will operate at the intersection of platform engineering and developer experience (DevEx) . You will design and evolve internal platforms as products , reducing friction across the software development lifecycle while maintaining strong standards for reliability, security, and compliance. While this role includes opportunities to work on observability systems, prior experience in observability platforms is not required - we value engineers who can learn quickly and apply strong platform fundamentals. You’ll use tools like Terraform, Kubernetes, Helm, ArgoCD, and DataDog to build scalable platform primitives and improve developer workflows across the organization. What you’ll work on Owning and evolving Mark43's internal developer platform, focusing on reliability, scalability, and developer productivity Building self-service platform capabilities (Infrastructure-as-Code modules, GitOps workflows, golden paths, and onboarding templates) Improving developer experience (DevEx) by reducing friction in local development, CI/CD pipelines, deployments, and debugging workflows Designing and optimizing pipeline-as-code systems to improve build performance, reliability, and feedback cycles Driving adoption of GitOps and Infrastructure as Code best practices across the organization Leading initi atives to improve operational excellence, including system reliability, resilience, and incident response Partnering closely with Product, Engineering, and Security teams to align platform capabilities with business needs Owning and delivering large, cross-team platform initiatives that shape how engineers build and operate software at MARK43 Participating in a shared on-call rotation to support critical infrastruc ture What we expect from you 5+ years of experience in Platform Engineering, DevOps, and/or Developer Experience Strong experience with AWS and cloud-native architectures Deep experience with Kubernetes and containerized systems Strong experience with Infrastructure as Code (Terraform) and GitOps (e.g., ArgoCD) Experience building and optimizing CI/CD systems and pipeline-as-code workflows Demonstrated ability to improve developer experience and platform usability at scale. Strong systems thinking, including tradeoffs between reliability, cost, and developer velocity Understanding of security and compliance best practices in cloud environments What sets you apart Y ou take ownership of complex platform problems, from design through adoption You build platforms and abstractions that are adopted across engineering teams You proactively identify gaps in developer workflows and drive improvements You influence technical direction beyond your immediate team You balance developer velocity, reliability, and operational excellence You treat internal platforms as products, with a focus on usability and impact Preferred Qualifications Familiarity with defining SLOs, alerting strategies, instrumentation best practices Experience with developer platforms and modern bu
