Technical Sales Engineer – Data Centres

Job Description

Johnson Controls, a global leader in thermal management, mission-critical building systems, energy efficiency, and decarbonization, helps customers use energy more productively, reduce carbon emissions, and operate with the precision and resilience required in rapidly expanding industries such as data centers, healthcare, pharmaceuticals, advanced manufacturing, and higher education.

For more than 140 years, Johnson Controls has delivered performance where it really matters. Backed by advanced technology, lifecycle services and an industry-leading field organization, we elevate customer performance, turn goals into real-world results and help move society forward.

We have an exciting opportunity for a Technical Account Manager (TAM) – Data Centre Thermal Solutions. This role serves as the primary technical interface between Johnson Controls and key Data Centre customers across the Pacific region, with a specific focus on chilled water plants, precision cooling, and advanced thermal management solutions.

The TAM provides deep technical leadership across chiller systems, liquid cooling, and thermal plant architectures, while also taking ownership of technical pricing strategy and bid development for complex opportunities. This ensures solutions are not only technically robust but also commercially competitive and aligned with customer value expectations.

A core element of the role is supporting the Strategic Account Manager (SAM) to drive commercial growth. The TAM brings thermal engineering expertise, early-stage cooling design influence, and bid/pricing leadership that strengthens Johnson Controls’ commercial strategies and opens new business opportunities.

Operating within a matrixed organisation, the TAM aligns technical, commercial, and delivery stakeholders to ensure chiller and cooling plant solutions are positioned, designed, priced, and delivered to win in a competitive market.
