About Alto Software Group

Alto Software Group is a B2B SaaS company that powers more than half of all UK housing transactions each year. We create software solutions that connect businesses and consumers, delivering a one-stop shop for estate agents and home builders. Our goal is to drive efficiency, speed up transactions, reduce risk, and improve the end-customer experience. While we’re not a start-up, we have a start-up mindset and want our people to operate with this mindset so that we can achieve our ambitions.

The Role

We’re looking for a proactive, automation-first Digital Workplace Platform Engineer to join our team. This is a high-impact role responsible for the design, security, and continuous improvement of our group’s core enterprise infrastructure and endpoint fleet. Operating in a "best of both worlds" environment utilizing Google Workspace, Microsoft 365, macOS and Windows, you will act as a key technical authority. You will bridge the gap between complex cloud infrastructure and end-user productivity, ensuring that our technical framework supports all users seamlessly and securely.

What You’ll Do

• Engineering & architecture: You will own the design, configuration and maintenance of our enterprise cloud platforms.
• Automated lifecycle management: You will remove manual work by building modern provisioning workflows, such as zero-touch deployment, and by scripting away repetitive tasks.
• Identity & access: You will manage and secure user identities and groups across Active Directory/Entra ID, Google and LDAP, so that joiners, movers and leavers move through without friction.
• Tenant & platform migrations: You will lead and deliver tenant-to-tenant migrations, specifically Google Workspace to Google Workspace and Entra ID to Entra ID consolidations and restructures.
• Security & vulnerability remediation: You will work closely with the Security team to enforce OS and cloud security baselines, manage disk encryption, deploy endpoint protection and triage vulnerabilities.
• Tier-3 escalation: You will be the final escalation point for the EUC and Platforms teams, resolving the most complex infrastructure and operating system failures.
• Governance & tech lifecycle: You will oversee technology from budgeting and procurement through to secure decommissioning. You’ll also set infrastructure roadmaps and manage vendor SLAs.
• Stakeholder Engagement & education: You will keep technical baseline documentation sharp, mentor the wider Digital Workplace team and lead training for everyone from new starters to the C-suite.

What You Need to Be Successful

• Hands-on experience planning and delivering tenant-to-tenant migrations, or highly coupled integrated estates, across both Google Workspace and Entra ID.
• Expert-level configuration management for macOS and Windows.
• Experience scaling enterprise endpoint management through Microsoft Intune, Apple Business Manager and corporate identity providers (Entra ID, Google).
• Strong knowledge of virtualisation and cloud technology deployment.
• A track record of managing complex incidents through multi-service ticketing platforms (we use Freshservice) while holding to internal SLAs.
• An automation-first approach: you use scripting and tooling to standardise operations, enforce security baselines and cut out repetitive work.
• You’re comfortable acting as a technical authority and working without supervision. You can balance long-term roadmap planning with urgent escalations and bring cross-functional teams into technical alignment.
• Excellent communication skills. You can turn complex infrastructure plans into clear, friendly updates for non-technical colleagues and leadership.

There’s always room to grow and learn with our roles — please don’t be put off if you don’t have all of these. It’s more important that you’re passionate about improving the home moving and owning experience for everyone.

• Google Workspace and Microsoft 365
• Entra ID / Active Directory, Google identity, LDAP
• Microsoft Intune and Apple Business Manager
• macOS and Windows
• Freshservice
• Slack, Zoom, Jira, Gemini and Claude (familiarity)
