Apply →

As the Project Sustainability Lead, you will act as the primary technical authority for environmental compliance across major construction sites. You will spend your days guiding site teams through the complexities of BREEAM and LEED certifications, ensuring that every design and build phase aligns with rigorous green standards. By monitoring site performance and managing auditable documentation, you bridge the gap between high-level strategy and technical execution.

This role is fundamental to TSL’s “Build Beyond” strategy, directly impacting the carbon footprint of critical infrastructure like data centres and advanced manufacturing hubs. You represent the vital link that ensures technical construction does not come at an environmental cost, translating corporate ESG goals into measurable site-level achievements. Your work provides the concrete proof that large-scale industrial projects can meet modern climate and efficiency benchmarks.

This suits someone who possesses deep technical expertise in building certifications and enjoys the balance of being a strategic advisor while remaining hands-on with site inspections and data reporting.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission is to serve as the technical subject matter expert for sustainability on assigned construction projects. This involves leading the delivery of building certifications such as BREEAM, LEED, and WELL, ensuring all credits are secured and documented through a robust auditable trail. You will be responsible for developing site-specific environmental management plans and conducting regular inspections to ensure operational compliance. Beyond immediate project work, you will also support the Head of ESG in evolving the wider corporate 'Build Beyond' strategy and integrating these goals into daily site activities.

Key learning opportunities for this job

Candidates can expect significant exposure to complex technical facility construction, including data centres and pharmaceutical hubs, which have unique sustainability requirements. You will likely deepen your expertise in Life Cycle Assessment (LCA) tools like OneClick. There is also the opportunity to gain internal auditor experience for ISO14001 and potentially achieve advanced professional qualifications in BREEAM or LEED. Working under the Int. Head of Sustainability offers high-level mentorship in cross-border ESG reporting and strategy implementation.

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

The ideal candidate holds a degree in a sustainability-related discipline and brings at least three years of experience in construction-sector environmental support. You must have a proven track record of helping project teams navigate green building certification processes from start to finish. Technically, you should be comfortable handling large datasets for emissions reporting and possess strong report-writing skills. A background in health and safety or environmental auditing is highly valued, as is a collaborative mindset capable of influencing both site workers and executive project directors.

Advice to stand out and make a successful application

Focus your application on specific examples where you successfully secured building credits or managed complex environmental documentation on site. Highlighting your experience with specialized construction, such as logistics or manufacturing, will align well with TSL's core business. Show an analytical approach to data; TSL values the ability to translate site activities into auditable sustainability metrics. Demonstrating familiarity with Irish or European reporting requirements could also be a differentiator, given the company's international reach and the role's link to Ireland-based activities.

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

This role centers heavily on Low Carbon Construction and building efficiency. The focus is on ensuring that the physical structures built by TSL meet international best practices for energy, water, and waste management through the BREEAM and LEED frameworks. You will also contribute to the social and environmental compliance aspects of planning conditions. This includes monitoring site performance to prevent pollution and ensuring that the supply chain adheres to the sustainability standards set out in the company's ESG documents.

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

One major challenge will be managing diverse stakeholders with varying levels of sustainability knowledge, requiring you to clearly communicate the importance of compliance to busy project teams. You may also face pressure to maintain certification timelines while navigating the typical fluctuations of large-scale construction schedules. Data accuracy is another hurdle; ensuring the supply chain provides timely and valid evidence for credits requires persistence and attention to detail. Balancing site visits with the reporting needs of the corporate ESG function will require excellent time management.

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

A typical day might begin with a site inspection to monitor environmental compliance, followed by a meeting with project managers to review a certification tracker. You could spend the afternoon drafting a Construction Environment Management Plan or analyzing site data for monthly emission reports. Communication is a constant thread, whether providing internal training to site staff or responding to queries from external sustainability consultants. The role involves occasional national travel, so your day might be split between the Trowbridge base and various active project locations.

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

There is a clear path toward senior ESG leadership, as the role reports directly into the international sustainability function. Success in this position could lead to overseeing larger regional portfolios or taking on a more strategic role in developing the 'Build Beyond' business management system. Being involved in high-growth sectors like data centers places you at the forefront of the industry's most critical sustainability challenges, offering high visibility within the organization. Lateral moves into specialized environmental auditing or LCA consultancy are also possible.

The main stakeholders you might be interacting with

Internal stakeholders include Project Directors and site teams, whom you will advise and train. You will also collaborate closely with the Int. Head of Sustainability to align project outcomes with the global ESG strategy. Externally, you will be the point of contact for clients, environmental consultants, and building assessors. You will also engage frequently with the supply chain to collect the technical evidence required for project certifications.
