Full Job Description
The Role

The Manager, DevOps Engineering is a hands-on technical leader responsible for designing, building, and operating scalable, cloud-native systems. This role functions as a player-coach, actively contributing to infrastructure, CI/CD pipelines, and platform reliability while leading a team of engineers. This position is critical to accelerating delivery, improving system resilience, and reducing operational overhead through direct technical execution and leadership.

Key Performance Objectives
In the first 12-18 months, success will be measured by your ability to:
  • Implement a self-service DevOps platform that allows developers to deploy, test, and monitor applications independently.
  • Directly contribute to the design and implementation of core infrastructure, including Kubernetes (EKS), CI/CD pipelines, and infrastructure as code.
  • Deliver measurable improvements in deployment frequency, system uptime, and mean time to recovery (MTTR).
  • Ensure successful migration and ownership of cloud infrastructure (e.g., EKS) from external vendors to internal teams.
  • Drive continuous delivery adoption, including infrastructure-as-code, automated release orchestration, and real-time performance feedback loops.
  • Enhance system observability and resilience by leveraging advanced monitoring tools (e.g., New Relic, Dynatrace) and automated alerting for production systems.
  • Foster strong cross-functional collaboration with Development, QA, Product, and Security teams to align on delivery goals and operational excellence.

Primary Responsibilities & Deliverables
DevOps Strategy & Execution
  • Lead the end-to-end design and continuous improvement of DevOps and SRE practices.
  • Own CI/CD systems, cloud-native infrastructure, and deployment strategies across environments.
  • Actively design, build, and maintain cloud infrastructure (AWS, EKS, networking, IAM).
  • Write and maintain infrastructure as code (Terraform/CloudFormation).
  • Troubleshoot complex production issues and performance bottlenecks.

Team Leadership & Delivery Management
  • Mentor engineers through pairing, code reviews, and hands-on guidance.
  • Allocate capacity between support, project work, automation initiatives, and incident response.

Platform & Infrastructure Ownership
  • Continue current adoption of infrastructure as code (Terraform/CloudFormation) and container orchestration (Kubernetes, Docker).

Cross-Team Collaboration
  • Act as a key partner for Development, QA, and Security teams to streamline release cycles and eliminate delivery bottlenecks.
  • Participate in technical architecture reviews and post-mortems to ensure the production readiness of all systems.

Success Profile (Qualifications & Experience)
Education & Leadership
  • Bachelor's degree in Computer Science, Engineering, or related discipline.
  • 5+ years in DevOps or SRE roles, with 3+ years of direct people leadership.

Technical Expertise
  • Mastery of cloud platforms (preferably AWS) and orchestration (Kubernetes).
  • Experience with infrastructure tools (Terraform, CloudFormation).
  • Skilled in CI/CD systems (Jenkins, GitLab CI/CD, CircleCI) and monitoring tools (New Relic, Dynatrace).
  • Strong knowledge of configuration management tools (Ansible, Puppet, or Chef).
  • Experience with API Gateway platforms (AWS API Gateway, Apigee).

Performance & Metrics-Driven
  • Proven ability to use telemetry (logs, traces, metrics) to diagnose and improve system performance.
  • Deep understanding of modern deployment strategies, including canary, blue/green, and rolling deployments.

Work Environment
  • Willingness to participate in off-hours support rotations, including evenings, weekends, and holidays when needed.
  • Committed to continuous improvement, ethical delivery, and maintaining strong stakeholder relationships.


Benefits
  • Highly rated and competitive medical plans.
  • 401 (k) with company match and immediate vesting.
  • 1-on-1, personalized health coaching.
  • Many other voluntary benefits.
