DevOps Engineer

Come, Innovate, Build, Disrupt & Thrive!

Position Overview

KēSTA I.T. is seeking a remote DevOps Engineer to own production reliability, from safe releases and monitoring to incident response and the private cloud infrastructure behind them.

This role is the single point of accountability for production. Today the whole team is informally on call. This position takes ownership of emergency escalation and then focuses on making escalations rare through better releases, alerting, and automation.

The work spans the full delivery and operations stack: Azure DevOps YAML pipelines and release process, a Linux (Debian) and Windows server fleet, a private cloud built on Proxmox hypervisors, test automation in the pipeline, and monitoring with Datadog and Zabbix. There is no public-cloud infrastructure here, and Kubernetes, Terraform, and public-cloud IaC tooling are not required.

This is a Principal engineering role on a team of about 10, including 5 in-house peers and a team in Spain. The role takes direction from the principal engineer and works in a fully remote, highly self-directed way. The first priority is getting up to speed on existing systems, then owning them end to end.

Success looks like safe, repeatable deployments, alerts that page on the right things, secrets and credentials that never expire unnoticed, and runbooks that other people can follow.

Key Responsibilities

• Own the release process end to end, including pipeline templates, staged rollouts across regional data servers so one failure never blocks the rest, the Sandbox-to-Production gate, and rollback decisions.
• Own the Azure DevOps pipeline estate, including YAML pipelines, the shared templates repository, self-hosted agent health (disk, memory, SDK caches, retention), the hosted-agent fallback, and build capacity.
• Share and cover organization-level administration of GitHub and Azure DevOps, including access, branch protection, service connections, and the secrets inventory.
• Operate the Linux fleet, including systemd services, nginx, MySQL 8.4 (backups, memory behavior, upgrades), Debian PBX VMs on Proxmox, and the SSH-driven mass-upgrade tooling that pushes software to every PBX.
• Operate the Windows environment, including SQL Server and IIS.
• Own the private cloud on Proxmox hypervisors, including maintaining and extending the in-house provisioning service that drives the Proxmox API, and understanding how it behaves when it fails partway through.
• Keep test automation running in the pipeline, including unit tests on every commit, the live integration suite against Sandbox phone systems, and the Playwright browser suite. Fix the cause of flaky tests or remove them.
• Own monitoring and alerting in Datadog (APM, logs, host agents and their installer) and Zabbix, tuning alerts to page on the right things and building per-service dashboards.
• Manage secrets and expiring credentials, including Azure Key Vault, pipeline variable groups, certificates, personal access tokens, and service connections, and maintain an inventory so nothing expires unnoticed.
• Run incidents from triage and communication through fix or rollback, then write the post-incident note and the runbook that prevents a repeat.
• Own emergency escalation for production and work to reduce the need for it over time.
• Manage capacity and system hygiene, including hypervisor overcommit, disk retention, log volume, firewall (nftables), TLS, and access reviews.
• Script repeatable tasks in bash, PowerShell, or C#, and read C# well enough to diagnose a failing service.
• Use AI-assisted and agentic coding tools in operations work.

Required Qualifications

• 5+ years operating .NET services in production on Linux and Windows.
• Azure DevOps pipelines authored from scratch, including YAML, templates, self-hosted agents, environments, and approvals.
• CI/CD pipeline maintenance and release deployment experience.
• Hands-on administration of MySQL and SQL Server, including backup and restore, performance basics, and handling a database process consuming excessive memory.
• Experience with nginx, systemd, SSH, and Debian or Ubuntu administration.
• Hands-on production experience with Datadog or an equivalent (APM, log pipelines, monitors), beyond viewing dashboards.
• Experience as the on-call person for systems they operated, and experience running incidents.
• Networking fundamentals: DNS, TLS certificates, firewalls, VPN, and reverse proxies.
• Experience with a hypervisor (Proxmox preferred, VMware or KVM acceptable), including automating it through its API rather than only using its console.
• Ability to read and run Playwright and xUnit suites in a pipeline and distinguish a flaky test from a broken one.
• Scripting ability in bash, PowerShell, or C#, and ability to read C# well enough to diagnose a failing service.
• Strong understanding of AI-assisted coding and agentic coding tools for operations work.
• Ability to work fully remote and self-directed, and to write runbooks that others can follow.
• Candidates must be authorized to work without visa sponsorship; sponsorship is not available for this role.

Preferred Qualifications

• Experience with Zabbix, Wasabi or S3, Redis, and Azure Key Vault.
• Experience using agentic coding tools for operations work.
• Telephony experience, including 3CX or VoIP.
• MSP industry experience.

Work Environment & Physical Requirements

• Fully remote role with no on-site requirements.
• Highly independent, self-directed work with a distributed team that includes colleagues in Spain.
• Production ownership includes emergency escalation and incident response.

Available Benefits

• Medical Benefits (Platinum level plans available)
• Work from home / Hybrid / Onsite options
• PTO
• Holiday Pay
• VTO
• 401K
• Charitable Match
• Training reimbursement
