Senior Linux Systems Engineer

Description About the Role  We are looking for a self-driven DevOps Engineer who thrives in a fast-paced environment and takes ownership of infrastructure, automation, and deployment pipelines. You are someone who can independently diagnose and solve complex problems and who consistently brings new ideas to improve how we build and ship software. In this role, you will play a critical part in shaping our cloud infrastructure, CI/CD workflows, and developer tooling — working across the full stack of systems that keep our platform running reliably and efficiently. What is your mission?  As a DevOps Engineer, you will design, provision, and maintain our AWS infrastructure, working with services such as VPC, EC2, CloudFront, Lambda, and S3. You will build and manage CI/CD pipelines in Jenkins and GitLab CI to support fast, reliable software delivery, and you will maintain our infrastructure as code using Terraform. You will automate operational tasks with Bash and develop Node.js tooling to support build processes, including NPM-based application builds and deployments. You will define effective Git workflows and branching strategies, monitor infrastructure health, respond to incidents, and work closely with engineers to remove bottlenecks. You will also continually research and introduce tools, practices, and improvements that enhance reliability, security, and the overall developer experience. Responsibilities Manage and troubleshoot Ubuntu/Debian systems, including service configuration and performance tuning. Apply strong networking fundamentals across Linux and AWS environments. Build and maintain AWS infrastructure (VPC, EC2, S3, CloudFront, Lambda). Implement secure networking, access controls, and lifecycle policies in AWS. Write and maintain Terraform for infrastructure‑as‑code. Automate operational tasks with Bash and support build tooling with Node.js. Build CI/CD pipelines using Jenkins or GitLab CI, enforcing best practices for artifacts, secrets, and deployments. Define and maintain effective Git branching strategies. Own problems end‑to‑end, from investigation to resolution. Communicate clearly and collaborate with engineering teams to improve reliability and developer experience. Proactively introduce tools, improvements, and best practices to evolve DevOps operations. Cellebrite is an equal opportunity/affirmative action employer.
