The Atacama Large Millimeter/submillimeter Array (ALMA) is the world’s preeminent facility for millimeter and submillimeter-wave astronomy with transformational capabilities to study the origin and evolution of galaxies, stars and planets. ALMA consists of 66 antennas located on the Chajnantor plateau, 5000 meters altitude in northern Chile, and equipped with receivers covering atmospheric windows between 30 and 950 GHz.

ALMA is a partnership of the European Organisation for Astronomical Research in the Southern Hemisphere (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile. ALMA is funded by ESO on behalf of its Member States, by NSF in cooperation with the National Research Council of Canada (NRC) and the National Science Council of Taiwan (NSC) and by NINS in cooperation with the Academia Sinica (AS) in Taiwan and the Korea Astronomy and Space Science Institute (KASI).

ALMA continued development and operations are led by ESO on behalf of its Member States; by the National Radio Astronomy Observatory (NRAO), managed by Associated Universities, Inc. (AUI), on behalf of North America; and by the National Astronomical Observatory of Japan (NAOJ) on behalf of East Asia.

The Joint ALMA Observatory (JAO) provides the unified leadership and management of the continued development, commissioning and operation of ALMA.

Head of the ALMA Department of Engineering (Head of ADE)

Duties and Responsibilities

The Joint ALMA Observatory (JAO) is seeking a senior engineering manager to lead the ALMA Department of Engineering (ADE), which is responsible for leading a large, multidisciplinary engineering team at the Joint ALMA Observatory in Chile consisting of over a hundred staff. The Head of ADE also plays a key role in supporting the scientific mission of ALMA by ensuring engineering systems meet the observatory’s high availability and precision requirements.

The department’s primary mission is to ensure the reliable operation and long-term sustainability of ALMA’s technical infrastructure, including the upkeep, oversight, and improvement of high-technology systems and infrastructure such as antennas, power systems, scientific instrumentation, and site facilities with a strong focus on sustainable operational performance and effective risk management and mitigation.

The position also entails proactive risk management in response to aging systems through implementation of sustainability-driven mitigation strategies in partnership with the ALMA Integrated Engineering Team (IET) to optimize maintenance plans, establish and monitor key performance indicators (KPIs), and continuous assessment of risks.

This role demands strategic leadership to guide the department through the next 5-10 years, a critical transition period for the observatory as a major upgrade, the Wideband Sensitivity Upgrade (WSU), of the complete ALMA signal chain is installed and brought to full operation. This requires strong coordination across departments, particularly with Science Operations and Computing, to maintain operational continuity and to coordinate effective management through the transition to the fully operational WSU system.

The position also requires commitment to effective team leadership and staff management to build a high-performance team in a multi-cultural, multi-national environment at the observatory, and maintaining strong collaborations with ALMA's international partners.

Main Responsibilities

• Provide strategic leadership to sustain, optimize, and enhance the long-term effectiveness of engineering operations at the JAO, with a primary focus on reliability and sustainability.
• Lead the Engineering Department through the ALMA Wideband Sensitivity Upgrade (WSU) transition, ensuring effective coordination of legacy and WSU systems and defining future engineering workflows.
• Build and manage a high-performance team through best practices in people management, including training, certification, professional development, team empowerment and cross-team collaborations.
• Oversee departmental resources, including budgeting, staffing, and strategic personnel allocation for projects and operations.
• Ensure delivery of engineering outcomes, including:
  • Integration and operational implementation of system upgrades;
  • Performance monitoring and characterization of engineering systems;
  • Identification and implementation of operational improvements;
  • Preventive and corrective maintenance of all systems and infrastructure;
  • Development and execution of comprehensive maintenance, risk management, and obsolescence management plans for all observatory systems, including antennas, scientific instrumentation. power systems, facilities, and site utilities.
• Monitor engineering performance, analyze trends, oversee fault reporting and resolution processes, and manage system configuration and health tracking.
• Coordinate and monitor array reconfiguration and related antenna transport logistics.
• Enforce compliance with safety standards and policies and promote a strong safety culture within the ADE.
• Collaborate with the ALMA Integrated Engineering Team (IET) on obsolescence mitigation, KPI monitoring, and optimization of maintenance strategies.
• Participate in the JAO Operations Team (JOT) to align operational planning, coordinate parallel operations during the WSU transition, and implementing and maturing the future WSU operations.
• Contribute to observatory-wide strategic planning as a member of the Core Management Team (CMT).
• Represent ADE in interactions with ALMA Executive organizations and external partners related to infrastructure, procurement, or engineering development.
• Contribute to long-term technology strategy by identifying emerging technologies or practices that can improve observatory operations or sustainability.
• Perform other duties as assigned by the ALMA Deputy Director of Operations.
