As the Assistant General Manager for Sustainability Development, you will be the primary architect of the ESG strategy for a major industrial manufacturer. You will oversee the transition from high-level policy to operational reality, managing a dedicated team to improve energy efficiency, resource management, and supply chain ethics across multiple business units. Your days will involve guiding top executives on climate risks while ensuring rigorous data compliance for international reporting standards.

This role is critical because the automotive manufacturing sector faces intense pressure to decarbonize. By leading sustainability for an OEM supplier, you are directly shaping the ecological footprint of the transport industry. You will have the unique opportunity to implement circular economy principles and carbon reduction roadmaps that have a measurable impact on the regional industrial ecosystem.

This suits someone who possesses over a decade of leadership experience in industrial ESG and thrives when bridging the gap between corporate governance and technical engineering. You should be a bilingual strategist comfortable influencing both the factory floor and the boardroom.

Preguntas frecuentes

The primary mission is to spearhead the corporate ESG strategy by translating high-level business goals into a structured sustainability roadmap. This involves setting governance frameworks and performance targets that span across several manufacturing business units to ensure a unified approach to sustainability. You will be responsible for overseeing enterprise-wide initiatives such as carbon reduction, energy management, and responsible supply chain practices. A significant portion of the role involves monitoring performance data and ensuring that all environmental and social disclosures comply with both national laws and international customer requirements.

Key learning opportunities for this job

In this position, you will gain deep expertise in automotive industry ESG standards, learning how to navigate the complex compliance requirements of global original equipment manufacturers (OEMs). This offers a rare view into the specific decarbonization challenges of the motor vehicle supply chain. You will also sharpen your skills in strategic change management by embedding sustainability into core manufacturing processes. Exposure to senior leadership as a strategic advisor on climate risk will provide high-level professional development in corporate governance and long-term value creation.

How does the ideal candidate look like (experience, skills)?

The ideal candidate brings at least 10 to 15 years of experience in ESG or EHS, with a proven track record of leading sustainability teams in a manufacturing or industrial context. An academic background in engineering or environmental management is highly preferred to handle the technical aspects of resource efficiency. Fluency in both Thai and English is essential for effective communication with local operations and international stakeholders. You should demonstrate a strong grasp of ESG reporting frameworks and possess the professional maturity to negotiate with regulators, auditors, and C-suite executives.

Advice to stand out and make a successful application

Focus your application on your ability to quantify impact. Provide specific examples of where you successfully reduced carbon intensity or improved resource efficiency in a manufacturing setting, as the company values concrete performance targets. Since this is an Assistant General Manager role, highlight your leadership philosophy and experience in managing diverse teams across different functions. Showing that you understand the specific pressures of the automotive supply chain and OEM relationships will significantly differentiate you from generalist ESG candidates.

What aspects of the company's sustainability is this role likely to focus on?

The role will likely concentrate on decarbonization and energy efficiency, as these are critical for the manufacturing sector. You will likely manage projects related to renewable energy adoption and resource-efficient production to meet international automotive standards. Another core focus will be supply chain traceability and social governance. Ensuring that the group's sourcing practices meet the high ethical standards expected by global car brands is a major component of maintaining the company's competitive advantage in the OEM market.

What are the main challenges someone in this role might face?

One of the toughest challenges will be driving cross-functional alignment. You must convince departments like procurement, finance, and engineering to prioritize sustainability metrics alongside traditional KPIs like cost and production volume. Additionally, keeping up with evolving global regulations in the ESG space requires constant vigilance. Ensuring that a diverse group of subsidiaries all maintain consistent data quality for external reporting can be technically and logistically demanding.

How could a typical day look like for someone in this position?

A typical day might begin with a strategy review session with the CEO or Managing Director to discuss long-term sustainability risks. Afterward, you might move to the plant floor or a regional office to meet with site managers and audit their current energy performance or waste management protocols. In the afternoon, you could spend time analyzing ESG data or drafting reports for external stakeholders. Your day often concludes with stakeholder engagement, perhaps coordinating with international customers or local regulators to ensure the company’s roadmap aligns with broader industry expectations.

What are the opportunities for professional growth and development in this role?

Given the 'Assistant General Manager' title, there is a clear path toward General Management or Chief Sustainability officer (CSO) roles as the company's ESG function matures. Success in this role provides high visibility within the group and the wider automotive industry. You will also have the opportunity to lead high-impact, multi-million dollar projects, such as regional carbon-neutral transitions. These achievements serve as significant milestones for any senior professional looking to establish themselves as a top leader in industrial sustainability in Southeast Asia.

The main stakeholders you might be interacting with

Your primary internal stakeholders include the CEO and Board of Directors, whom you will advise on ESG strategy. You will also work closely with functional heads in Engineering, EHS, and Procurement to implement sustainability policies at the operational level. Externally, you will interact with global automotive OEMs, environmental regulators, and ESG auditors. Building relationships with these groups is vital to ensure the company remains a preferred, compliant partner in the global manufacturing supply chain.
