## Job description

[About 3E:](https://www.3eco.com/why-3e/) 3E is a mission-driven company dedicated to creating a safer and more sustainable world. We offer award-winning regulatory intelligence and AI solutions to help organizations protect people and products. With over 35 years of experience and a global presence, we empower our customers with innovative compliance solutions. You will get to work at a company that combines startup agility with the stability of an industry leader. Partner with enterprise customers and global experts to advance environmental safety and solve complex data science challenges. Join us and make an impact!

About the Role: 3E is looking for a Senior AI Endpoint Engineer to join our global Service Desk team in Sofia, Bulgaria. This is a senior individual contributor role for someone who can combine hands-on employee support with technical leadership, endpoint expertise, automation, and continuous improvement. You’ll help keep day-to-day service desk operations running effectively while also looking beyond individual tickets to identify recurring issues, improve processes, strengthen documentation, and use AI and automation to make support more efficient. You’ll work across Microsoft 365, endpoint management, Windows and Mac environments, and a broad workplace technology landscape while partnering with colleagues across Security, Infrastructure, Engineering, and other teams. You’ll also play an important local role in supporting our Sofia office and equipment operations across Europe, while collaborating with a globally distributed team across multiple regions. Location: This position is based in Sofia and follows a hybrid working model, with two days per week in the office.

## What You’ll Do

- Provide senior-level support for internal employees across endpoint, workplace, and service desk technologies.
- Support and improve Microsoft 365, Entra ID, Intune, Windows, Mac, and related workplace technology environments.
- Manage ticket-based support while identifying recurring patterns and opportunities to prevent issues rather than repeatedly resolve them.
- Use AI and automation to improve service desk workflows, diagnostics, remediation, self-service, and the overall employee experience.
- Analyze service desk and endpoint information to identify root causes, reduce recurring demand, and improve service delivery.
- Participate in technology projects such as workstation migrations, integrations, and other workplace technology initiatives.
- Support Sofia office technology operations and equipment inventory and logistics for employees across Europe.
- Create and maintain clear technical documentation, employee-facing knowledge resources, and repeatable support processes.
- Partner with Security, Infrastructure, Engineering, and other teams to deliver secure, reliable workplace solutions.
- Mentor and support less experienced team members, sharing knowledge and helping raise the technical capability of the team.
- Help establish standards and scalable approaches that improve endpoint reliability and make effective support easier to deliver.
- Use data, employee feedback, and operational insights to recommend improvements and demonstrate measurable impact.

What Makes You a Great Fit Minimum Qualifications:

- Bachelor’s degree in Computer Science, Engineering, Information Systems, or equivalent practical experience.
- 6+ years of experience across service desk, endpoint, workplace, or related platform technologies, including senior-level internal employee support beyond basic ticket handling and using Jira or a similar ticketing or service management platform.
- Fluent written and verbal English, with the ability to communicate effectively with global customers and colleagues.
- Hands-on experience with Microsoft 365, Entra ID, Intune, or similar endpoint management technologies, in both Windows and Mac environments.
- Demonstrated ability to troubleshoot complex issues, identify root causes, and implement preventative improvements through automation, standards, process improvements, or documentation.
- Hands-on experience implementing AI-enabled Service Desk or endpoint workflows, such as ticket triage, knowledge retrieval, diagnostics, remediation, or self-service, using enterprise data with appropriate access controls, validation, and human oversight.
- Experience collaborating across Security, Infrastructure, Engineering, or other technology teams, while mentoring colleagues and sharing technical knowledge.
- Customer-focused and outcome-oriented, with evidence of measurable improvements to service quality, efficiency, reliability, or employee experience.

Preferred Qualifications:

- Experience operating and improving endpoint platforms at scale in modern, cloud-first environments.
- Familiarity with reliability engineering, observability, platform engineering, or advanced automation concepts.
