About The Position

We are looking for an experienced, forward-thinking Senior DevOps Engineer to join our newly formed DevOps team within our Market Data Engineering organization. In this role, you will be a critical resource working with Engineering and Product teams to re-design, build, automate, and scale our developer enablement ecosystem. You will partner with multiple agile development teams building complex, high performance computing solutions, championing a modern, security-focused DevOps culture. Beyond traditional CI/CD, you will explore and implement AI-enabled automation using LLMs like Claude or Gemini to optimize pipelines, build developer self-service tooling, and accelerate software delivery.

Requirements

  • 5+ years of experience in DevOps or Platform Engineering, ideally supporting multiple agile software development teams
  • Strong experience designing and maintaining CI/CD pipelines using Git, GitLab CI/CD, and Jenkins, including pipeline-as-code and shared libraries
  • Strong proficiency in Python for software development, systems automation, internal tooling, or integration development
  • Hands-on experience administering Linux environments and working with virtual machines and Docker-based containerized applications
  • Practical experience managing binary repositories, dependencies, and artifact lifecycles using JFrog Artifactory or a comparable platform
  • Proven experience deploying and managing workloads in AWS, including EC2, S3, VPC, IAM, security groups, and related networking concepts
  • Practical understanding of secure software development lifecycle principles, vulnerability management, container security, and secrets management
  • Demonstrated success collaborating with agile software development teams using Scrum, Kanban, or similar methodologies
  • Experience identifying operational inefficiencies and translating them into scalable automation, tooling, or platform improvements

Nice To Haves

  • Experience using large language models for code generation, log analysis, pipeline triage, developer support, or workflow automation
  • Experience building, integrating, or consuming Model Context Protocol services, AI agents, or similar AI-enabled development tools
  • Experience supporting high-performance, low-latency, financial technology, or other technically complex software environments
  • Familiarity with infrastructure-as-code tools and container orchestration platforms
  • Relevant AWS, DevOps, security, or cloud certification

Responsibilities

  • Design, build, optimize, and maintain robust, high-performing CI/CD pipelines across multiple agile development teams using Git, GitLab CI, and Jenkins
  • Research, design, and implement automated workflows, pipeline triaging, and developer tooling using AI models (such as Claude and Gemini) integrated via Model Context Protocol (MCP)
  • Design and manage software supply chain workflows using JFrog Artifactory, ensuring secure dependency management, artifact caching, and license compliance
  • Integrate automated security scanning (SAST/DAST, container scanning, secret detection) directly into delivery pipelines, driving a "shift-left" security culture
  • Develop clean, maintainable, and reliable automation scripts and custom integrations using Python
  • Manage and optimize Linux operating environments across both traditional virtual machines (VMs) and modern containerized platforms using Docker
  • Provision, monitor, and scale cloud infrastructure on AWS, utilizing core services such as EC2, S3, VPCs, and IAM
  • Serve as a DevOps champion within agile sprint teams, participating in ceremonies, advising on deployment strategies, and removing operational bottlenecks

Benefits

  • Opportunities to expand your expertise through hands-on technical challenges, collaboration, and continued learning
