About the Job

Requirements

At least 5 years of experience as a systems administrator, endpoint engineer, or similar, including at least 2 years packaging and deploying software at scale using tools such as Intune, SCCM/ConfigMgr, Jamf, Munki, Chocolatey, or winget.
Hands-on experience packaging Windows software, including MSI, EXE, and MSIX installers, silent switches, detection rules, per-user versus per-machine installs, and x64/arm64 architectures.
Hands-on experience packaging macOS software, including PKG and DMG packages, app bundles and bundle IDs, and universal versus architecture-specific builds.
Proficiency with PowerShell and Bash, including reading and fixing installer wrappers.
Experience automating deployments through pipelines such as GitHub Actions or Azure DevOps, not only through a management console.
Experience using AI agents to delegate tasks and review, validate, and correct their output.
Ability to read TypeScript and YAML well enough to identify issues in agent-generated changes.
Ability to diagnose failed installs from logs, exit codes, and metadata on devices that cannot be accessed.
Ability to reverse-engineer poorly documented installers, find stable download URLs and version sources, and identify and document apps that cannot be packaged due to login requirements, paywalls, or bot protection.
Strong written English for an asynchronous-first team.

Responsibilities

Own end-to-end delivery and reliability of third-party application packages across Windows and macOS, from installer analysis and automated validation through production patching.
Use packaging expertise, scripting, TypeScript, CI/CD, and AI-assisted engineering to ship applications and continuously improve catalog automation.

Desired Qualifications

Experience maintaining packages in public repositories such as winget-pkgs, Chocolatey Community, Homebrew Cask, or AutoPkg.
Experience with Python or Go, AWS, vulnerability/CVE data, or virtual-machine-based install testing.

Why You Belong Here

As a Software Engineer at Cresteo, you'll be more than just a developer; you will be part of transforming the tech industry through our honest, transparent, and people-centric approach.

Your role will be diverse and dynamic. You'll be instrumental in developing and maintaining our software solutions, working with a varied technology stack, and ensuring that our products are functional, efficient, reliable, and scalable.

By joining us, you're not just choosing a job; you're aligning with a vision that values the human side of tech, where your skills and passion are recognized, nurtured, and celebrated.

What We're Looking For

- 5+ years as a systems administrator, endpoint engineer or similar, including at least 2 years packaging and deploying software at scale (Intune, SCCM/ConfigMgr, Jamf, Munki, Chocolatey, winget or similar)

- Hands-on Windows packaging: MSI, EXE and MSIX installers, silent switches, detection rules, per-user vs. per-machine installs, x64/arm64

- Hands-on macOS packaging: PKG and DMG, app bundles and bundle IDs, universal vs. architecture-specific builds

- Solid PowerShell and Bash: you can read and fix someone else's installer wrapper

- Experience automating deployments through pipelines (GitHub Actions, Azure DevOps or similar), not only through a management console

- You already work with AI agents: you delegate tasks to them, and you review, validate and correct what they produce. This is non-negotiable

- Comfortable reading TypeScript and YAML well enough to spot what's wrong in an agent-generated change. You don't need to be a developer

- You diagnose failed installs from logs, exit codes and metadata, on devices you can't access

- You can reverse-engineer poorly documented installers, find stable download URLs and version sources, and recognize when an app can't be packaged (login, paywall, bot protection) and write down why

- Maintaining packages in public repositories (winget-pkgs, Chocolatey Community, Homebrew Cask, AutoPkg)

- Python or Go, AWS, vulnerability/CVE data, VM-based install testing

- Strong written English for an async-first team

Own the end-to-end delivery and reliability of third-party application packages across Windows and macOS, from installer analysis and automated validation to production patching. Combine deep packaging expertise with scripting, TypeScript, CI/CD, and AI-assisted engineering to ship applications while continuously improving the automation behind the catalog.

Our Commitment to You:

USD above-average salaries

Unlimited PTOs after your first year (20 PTOs the first year)
Equipment for your setup
Great work/life balance
Honest, simple, and transparent culture
