Job description

Fitch Group is currently seeking a Senior Service Reliability Engineer to embed with Fitch Solutions development squads in Chicago, USA. The role is based out of our Chicago office.
As a leading, global financial information services provider, Fitch Group delivers vital credit and risk insights, robust data, and dynamic tools to champion more efficient, transparent financial markets. With over 100 years of experience and colleagues in over 30 countries, Fitch Group's culture of credibility, independence, and transparency is embedded throughout its structure, which includes Fitch Ratings, one of the world's top three credit ratings agencies, and Fitch Solutions, a leading provider of insights, data and analytics. With dual headquarters in London and New York, Fitch Group is owned by Hearst.
Fitch's Technology & Data Team is a dynamic department where innovation meets impact. Our team includes the Chief Data Office, Chief Software Office, Chief Technology Office, Emerging Technology, Shared Technology Services, Technology, Risk and the Executive Program Management Office (EPMO). Driven by our investment in cutting-edge technologies like AI and cloud solutions, we're home to a diverse range of roles and backgrounds united by a shared passion for leveraging modern technology to drive projects that matter to our organization and clients. We are also proud to be recognized by Built In as a "Best Place to Work in Technology" 3 years in a row. Whether you're an experienced professional or just starting your career, we offer an exciting and supportive environment where you can grow, innovate, and make a difference.

About the Team:
Fitch Solutions SRE provides Service Reliability Engineering expertise to Fitch's development organizations. This squad joins Core Engineering and other SRE groups as part of Cloud Infrastructure & Platform Engineering (CI&PE), serving as subject matter experts in cloud technologies, systems engineering, infrastructure automation, and DevOps tooling across Fitch Group. The role itself will be dedicated to ensuring excellence in Fitch Solutions services, with focus on new AI development.
How You'll Make an Impact:
  • You'll lead the delivery of reliable, scalable, mission-critical services. You'll guide squads on Kubernetes and modern deployment patterns.
  • Mentoring associate engineers and setting best practices for areas of expertise will help the team grow in knowledge and capabilities.
  • Partner closely with Fitch Solutions Development Squads and Operations to design and advance service builds, DevOps tooling, and drive operational excellence.
  • Partner with Core Engineering to architect and govern GitHub Actions CI/CD with quality gates, canary/blue-green strategies, and AI-assisted redeploy checks
  • Own observability in Datadog-define SLIs/SLOs, dashboards, alerting, and MS Teams integrations-and reduce incidents via telemetry-driven automation and blameless postmortems.
  • Champion AI-enabled operations using AWS Bedrock/SageMaker and Model Context Protocol (MCP) for log analysis, anomaly detection, incident triage, and workflow orchestration; establish adoption guardrails.
  • Define and enforce cloud guardrails and security controls (SCPs/IAM boundaries, OPA policies, tagging, centralized logging with AWS Config/CloudTrail/Security Hub) in partnership with Security and Risk.
  • Influence cross-functional roadmaps, lead complex release planning, and drive strategic platform initiatives across CI&PE; serve as an escalation point and participate in the L3 on-call rotation.

You May be a Good Fit if:
  • You have deep, hands-on experience in SRE, DevOps, or Platform Engineering across both AWS and Azure, with a strong track record operating Docker and Kubernetes in production environments.
  • You're highly proficient in administering both Linux and Windows, and have practical, enterprise-level experience supporting IIS/.NET applications as well as Java Spring Boot services.
  • You have built and maintained CI/CD pipelines (primarily GitHub Actions; Bamboo experience a plus) with DevSecOps principles baked in-integrating security scans, policy-as-code, and compliance gates-and script confidently in Python, PowerShell, or Bash.
  • You have experience with cloud security best practices (IAM, secrets management, container/image scanning) and understand core infrastructure fundamentals (networking, storage, DNS) and APM/telemetry tooling.

What Would Make You Stand Out:
  • Practical experience with agentic AI for operations-incident triage, runbooks, and change management-with clear guardrails, auditability, and human-in-the-loop controls.
  • Supporting AI/ML workloads at scale: SageMaker endpoints, GPU node groups, autoscaling, and Kubernetes-based model serving.
  • Policy-as-code (OPA) and compliance implementation across CIS, NIST, ISO 27001, with automated remediation integrated via CSPM tools (e.g., Wiz).
  • Applying AI in CI/CD, observability, and incident response using AWS Bedrock/SageMaker and Model Context Protocol (MCP).
  • Hands-on Agile delivery experience, actively participating in stand-ups and sprint ceremonies.

Why Choose Fitch:
  • Hybrid Work Environment: 2 to 3 days a week in office required based on your line of business and location
  • A Culture of Learning & Mobility: Dedicated trainings, leadership development and mentorship programs designed to ensure that your time at Fitch will be a continuous learning opportunity • Investing in Your Future: Retirement planning and tuition reimbursement programs that empower you to achieve your short and long-term goals
  • Promoting Health & Wellbeing: Comprehensive healthcare offerings that enable physical, mental, financial, social, and occupational wellbeing
  • Supportive Parenting Policies: Family-friendly policies, including a generous global parental leave plan, designed to help you balance career and family life effectively
  • Inclusive Work Environment: A collaborative workplace where all voices are valued, with Employee Resource Groups that unite and empower our colleagues around the globe
  • Dedication to Giving Back: Paid volunteer days, matched funding for donations and ample opportunities to volunteer in your community

Fitch is committed to providing global securities markets with objective, timely, independent and forward-looking credit opinions. To protect Fitch's credibility and reputation, our employees must take every precaution to avoid conflicts of interest or any appearance of a conflict of interest. Should you be successful in the recruitment process at Fitch Group you will be asked to declare any securities holdings and other potential conflicts prior to commencing employment. If you, or your immediate family, have any holdings that may conflict with your work responsibilities, you may be asked to divest yourself of them before beginning work.
Fitch is proud to be an Equal Opportunity and Affirmative Action Employer. We evaluate qualified applicants without regard to race, color, national origin, religion, sex, sexual orientation, gender identity, disability, protected veteran status, and other statuses protected by law.
FOR CHICAGO ROLES ONLY: Expected base pay rates for the role will be between $135,000 and $145,000 per year. Actual salaries will be determined on an individualized basis and may vary based on factors including but not limited to education, training, experience, past performance, and other job-related factors. Base pay is one part of Fitch's total compensation package, which, depending on the position, may also include commission earnings, discretionary bonuses, long-term incentives, and other benefits sponsored by Fitch.
