As the strategic lead for sustainability at OMNES, you will bridge the gap between high-level environmental ambitions and the daily realities of fashion production. Reporting directly to the CEO, you will own the entire roadmap, from setting measurable targets to auditing supply chains and securing B Corp recertification. This is a hands-on position that moves beyond theory to embed responsible practices directly into the design, buying, and marketing functions of a growing womenswear brand.

This role is critical because it ensures that fashion design and environmental integrity are inseparable. You will be the technical authority ensuring every recycled material claim is substantiated and every supplier meets rigorous ethical standards. In an industry facing intense scrutiny over greenwashing, your work provides the data-driven backbone that allows the brand to scale responsibly without compromising its core values.

This suits someone who possesses deep technical knowledge of apparel supply chains and a commercial mindset. You should be comfortable navigating complex UK and EU regulations while influencing senior leadership to make sustainable decisions that also support business growth.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission is to own and evolve the sustainability roadmap for the entire brand. You will translate broad environmental goals into actionable KPIs across product development, sourcing, and operations. This involves setting science-based targets and ensuring they are tracked with high-quality data. Beyond strategy, you are responsible for operationalizing responsible sourcing. You will work with the design and production teams to select preferred materials, validate certification claims, and manage the supplier audit process to ensure social and environmental compliance throughout the tier-one and tier-two supply chains. Finally, you act as the brand's internal expert on regulatory compliance and external claims. You will audit marketing communications to prevent greenwashing risks and ensure the business is prepared for upcoming UK and EU sustainability legislation, such as extended producer responsibility or supply chain due diligence requirements.

Key learning opportunities for this job

You will gain deep expertise in B Corp recertification within a high-growth retail environment, managing complex evidence collection and impact improvement strategies. This role offers a unique vantage point on how a circular fashion business scales while maintaining rigorous standards. Exposure to emerging textile regulations across the UK and EU will be a constant, providing you with a cutting-edge understanding of legal compliance in the fashion sector. You will also refine your skills in lifecycle thinking and material traceability by working directly with global suppliers and innovative fabric developers.

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

The ideal candidate brings at least six years of experience in sustainability or responsible sourcing, specifically within the fashion or consumer goods sectors. You should have a proven track record of moving from strategy to implementation, demonstrating that you can get 'into the weeds' of supplier data and material certifications. Technical proficiency in carbon accounting and supply chain mapping is essential. On a soft-skills level, you need the commercial acumen to understand margin and quality constraints, alongside the confidence to challenge senior stakeholders when sustainability goals are at risk.

Advice to stand out and make a successful application

To stand out, highlight specific examples where you have integrated sustainability into commercial decision-making. OMNES values pragmatism, so demonstrate how you have balanced environmental targets with business growth or product quality in previous roles. Since this role involves B Corp management, any experience you have with the B Impact Assessment or similar certification frameworks should be front and center. Show that you understand not just the 'why' of sustainability, but the technical 'how' of evidence-based reporting and data management.

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

The focus is heavily weighted toward material integrity and supply chain transparency. You will be scrutinizing the environmental footprint of fibers, ensuring recycled content is genuine, and pushing for better waste and water management at the factory level. There is also a significant emphasis on responsible communication. In a brand that prides itself on its credentials, you will be the gatekeeper ensuring that every marketing claim is backed by robust documentation, thereby protecting the brand from greenwashing litigation and reputational damage.

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

The most significant challenge will be balancing sustainability with commercial scalability. As a growing brand, OMNES will face pressures on margins and lead times; you must find ways to maintain high ethical standards without stalling the business's operational momentum. Additionally, data collection from disparate suppliers can be difficult. You will need to build strong relationships with factory owners to ensure transparency and timely reporting of environmental metrics, often without the massive leverage that larger global conglomerates might possess.

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

A typical day might begin with a cross-functional meeting with Design and Buying to review upcoming collection materials and their associated certifications. You might spend your midday hours interrogating supplier audit reports or updating the B Corp evidence folder for the next assessment cycle. In the afternoon, you could be advising the Marketing team on the wording for a new campaign to ensure it aligns with the Green Claims Code. The day often concludes with strategic planning, perhaps analyzing carbon data or preparing a briefing for the CEO on new EU textile regulations.

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

Given that this role reports directly to the CEO in a growing business, there is a clear path toward strategic leadership. You could eventually oversee a broader ESG department as the team expands, moving from a hands-on manager to a director-level strategist. There are also opportunities to become a thought leader in the sustainable fashion space, representing the brand at industry forums and contributing to broader sector-wide initiatives. The high visibility of this role within a B Corp fashion house provides a powerful platform for professional development.

The main stakeholders you might be interacting with

Your primary internal stakeholders include the CEO and the leadership team, whom you will advise on risks and strategy. You will also collaborate daily with the Design, Buying, and Production teams to implement sustainable sourcing standards. Externally, you will interact with factory managers and material suppliers to drive transparency. You will also liaise with third-party certification bodies, legal advisors, and industry organizations to ensure the brand remains at the forefront of sustainability best practices.
