Apply →

As a Sustainability Analyst, you will act as a central hub for environmental and social data, supporting the annual reporting cycle from collection to assurance. Working closely with the Reporting Manager, you will translate complex organizational activities into clear disclosures for shareholders, regulators, and external agencies. Your daily focus centers on maintaining high-quality data streams that reflect the company’s real-world progress.

This role is critical because construction has a massive environmental footprint, and the Irish housing market demands high transparency. You will be at the forefront of documenting how residential development can transition toward carbon neutrality and biodiversity net gain. By ensuring the integrity of reporting on social impact and supply chain ethics, you directly influence how the company creates lasting value for local communities beyond just building houses.

This suits someone who possesses a meticulous eye for data and enjoys the challenge of coordinating with various departments. You should be comfortable explaining ESG requirements to non-specialists and eager to deepen your expertise in sustainability disclosure frameworks.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission centers on the end-to-end management of sustainability data. You will be responsible for gathering qualitative and quantitative information from various business departments to satisfy annual reporting requirements across environmental, social, and governance pillars. This includes tracking performance in areas like carbon emissions, waste, and biodiversity. Beyond data collection, you will support the Sustainability Reporting Manager in drafting disclosures for the Carbon Disclosure Project (CDP) and ensuring that all non-financial data is ready for external assurance. You are also tasked with maintaining sustainability policies and helping to embed the company's broader sustainability strategy into daily operations across the construction lifecycle.

Key learning opportunities for this job

Working in this role provides deep exposure to the practical application of GHG Protocol, particularly in managing complex Scope 3 emissions within a heavy-industry supply chain. You will gain hands-on experience with the third-party assurance process, which is becoming a standard requirement under new regulatory frameworks like the CSRD. Furthermore, the position offers a platform to learn about biodiversity and social value metrics specific to the construction sector. You will also have the chance to attend external conferences and engage with industry peers, providing a high-level view of how ESG trends are evolving at a national and international level.

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

The successful candidate should have a solid foundation in environmental management or data analytics. Experience with ESG reporting frameworks is essential, as is a working knowledge of carbon footprinting. Given the complexity of construction data, a strong ability to interpret trends and communicate technical insights to a non-technical audience is highly valued. Soft skills are just as vital as technical expertise. The ideal profile is proactive and solutions-focused, capable of managing multiple deadlines simultaneously. Someone who thrives in a collaborative environment and has the organizational discipline to oversee rigorous data verification processes will be a natural fit for the team.

Advice to stand out and make a successful application

To stand out, highlight any specific experience you have with data assurance or rigorous audit processes. Demonstrating that you understand the transition from 'best effort' reporting to 'audit-ready' disclosures will show you are prepared for the increasing maturity of the company's ESG strategy. Tailor your application by researching Cairn's 'Built For Good' philosophy. If you can speak to the social impact of large-scale residential development or the specific challenges of decarbonizing the Irish construction supply chain, you will demonstrate a level of commercial awareness that distinguishes you from more generic candidates.

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

This role is deeply embedded in the reporting side of the Environmental and Social pillars. On the environmental side, there is a heavy emphasis on decarbonization and carbon footprinting (Scopes 1, 2, and 3), as well as waste management and biodiversity protection on construction sites. On the social side, you will facilitate the reporting of workforce initiatives such as health and safety metrics, wellbeing, and Equality, Diversity & Inclusion (ED&I). You will also play a part in documenting the company's social impact, ensuring that the 'Built For Good' purpose is backed by verifiable data regarding community connection and development.

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

One of the main challenges will be standardizing data collection across a diverse range of construction sites and sub-contractors. Gathering timely and accurate data from stakeholders who may not view ESG reporting as their primary priority requires persistence, diplomacy, and strong relationship-building skills. Additionally, the candidate must navigate the rapidly evolving regulatory landscape for sustainability disclosures. Keeping up with changing standards while ensuring that current reports remain compliant and consistent over time adds a layer of technical pressure, especially during the annual audit and assurance window.

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

A typical day might begin with reviewing data submissions from site managers or supply chain partners to ensure accuracy. You could spend your morning analyzing carbon performance trends or drafting sections of a sustainability report. Mid-day might involve a meeting with the Health & Safety team to align on social metrics for the next quarterly update. In the afternoon, you might switch to a more collaborative task, such as delivering a sustainability orientation for a group of new graduates or attending a meeting with external ESG consultants. The day often concludes with administrative work related to policy maintenance or organizing documentation for an upcoming external audit.

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

The role offers a clear path toward becoming a Reporting Manager or ESG Lead. As the company continues to scale its sustainability commitments, the complexity of its reporting will grow, allowing the analyst to take on more strategic ownership of high-level disclosures and climate risk assessments. There are also opportunities for lateral skill development. By working across various functions like HR, Supply Chain, and Operations, you can gain a panoramic view of the business. This cross-functional exposure is excellent preparation for senior management roles that require a holistic understanding of how sustainability intersects with commercial success.

The main stakeholders you might be interacting with

Your internal stakeholders are diverse and varied, ranging from senior leadership and functional heads to site-based employees and project teams. You will collaborate closely with professionals in Health & Safety, HR, and Supply Chain to gather the raw data needed for your reports. Externally, you will interact with auditors, ESG consultants, and agencies like the CDP. You will also represent the company at industry events and engage with shareholders or industry peers, acting as an ambassador for the company's sustainability progress and reporting integrity.
