ESB Technologies

Irving / Global

DevOps Engineer

Job Description

You'll spend most of your time building and automating on-premises VMware infrastructure with Terraform and Docker, and the rest keeping a production AWS footprint healthy. The platform you're supporting handles emergency escalations for major consumer apps — high-volume, customer-facing, and growing.

About the team

Our client has been in the security business for 150 years and is now packaging its monitoring capability as a service for large enterprise and consumer platforms. This engineering group owns the infrastructure behind that service and is actively modernizing it: automating what was manual, containerizing what was hand-deployed, and migrating databases forward. The team uses Cursor for AI-assisted development and expects engineers to lean into it.

What you'll do

Design, build, and automate on-prem VMware infrastructure using Terraform and Infrastructure-as-Code practices

Containerize and deploy services with Docker, on-prem and in Amazon ECS

Build and maintain CI/CD pipelines in Bitbucket

Provide operational support for production AWS environments (incident response, performance, cost, hardening)

Contribute to PostgreSQL migration and modernization work

Administer and automate Linux systems at scale

Support integrations with third-party APIs and enterprise partners

Communicate clearly with engineering, product, and business stakeholders — this role has a lot of cross-team surface area

What you need

10+ years in DevOps, Infrastructure, or Platform Engineering

Hands-on experience building and administering VMware / on-premises infrastructure — not just consuming it

Deep Terraform and IaC expertise

Docker in production; Amazon ECS experience

CI/CD fluency, ideally with Bitbucket Pipelines

PostgreSQL experience, including at least one migration or modernization project

Strong Linux administration and scripting/automation

Strong troubleshooting instincts and comfort with production on-call realities

Clear, effective written and verbal communication

Nice to have

GCP exposure or cloud-to-cloud migration experience

Experience with AI-assisted development tools (Cursor, Copilot, etc.)

Background in high-volume, customer-facing production environments

Experience building platforms that integrate with external APIs / service providers

Before you apply

This role is majority on-prem.

You can work hybrid on-site in Irving, TX (DFW area) without relocation assistance

You have 10+ years in a DevOps, infrastructure, or platform engineering role

You have personally administered vSphere / VMware infrastructure — not just consumed VMs someone else built

You have written Terraform from scratch for infrastructure you owned, including at least one non-AWS provider

You have run Docker in production

You have hands-on experience with PostgreSQL in a migration, upgrade, or modernization project

If your background is cloud-only, this is not the right fit and we'd rather not waste your time.

Why this role

Most DevOps postings are cloud-only. This one is the reverse: real hardware, real hypervisors, and the mandate to modernize how they're run — with cloud experience as a complement, not the whole job. If you like on-prem engineering but want to work with modern tooling and an AI-forward team, this is a rare fit.
