About the Role

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.

Key Responsibilities

• CI/CD & Pipeline Engineering: Design, build, optimize, and maintain robust, high-performing CI/CD pipelines across multiple agile development teams using Git, GitLab CI, and Jenkins

• AI-Driven Automation: 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)

• Software Supply Chain Security: Design and manage software supply chain workflows using JFrog Artifactory, ensuring secure dependency management, artifact caching, and license compliance

• DevSecOps & Secure SDLC: Integrate automated security scanning (SAST/DAST, container scanning, secret detection) directly into delivery pipelines, driving a "shift-left" security culture

• Automation & Tooling: Develop clean, maintainable, and reliable automation scripts and custom integrations using Python

• Infrastructure & Platform Management: Manage and optimize Linux operating environments across both traditional virtual machines (VMs) and modern containerized platforms using Docker

• Cloud Infrastructure: Provision, monitor, and scale cloud infrastructure on AWS, utilizing core services such as EC2, S3, VPCs, and IAM

• Agile Collaboration: Serve as a DevOps champion within agile sprint teams, participating in ceremonies, advising on deployment strategies, and removing operational bottlenecks

Required Skills & Experience

• 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

Preferred Skills & Experience

• 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

What We Offer

• Foundational Impact: The opportunity to help shape Exegy’s DevOps strategy, architecture, automation practices, and supporting toolset

• Modern Technology: Work at the intersection of DevOps, software security, developer enablement, and AI-enabled automation

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

• Collaborative Culture: A supportive environment where DevOps partners directly with Engineering, Product, Security, and other technical teams to improve how software is built and delivered
