Sustainability Assurance Assistant Manager - Boutique Management Consultancy – Financial Services

As part of a leading UK (privately owned) Advisory firm, working closely with financial services clients across banking, insurance and building societies, this FS Consulting practice is expanding its Sustainability & Non-Financial Assurance capability.

This is a genuinely exciting opportunity for someone looking to move beyond traditional audit into a broader, consultancy-led role, or someone already in consultancy with this experience looking to step up. Here you will have early responsibility and real influence.

The role:

As a Sustainability Assurance Assistant Manager, you’ll play a hands-on role delivering limited assurance engagements across sustainability, ESG and non-financial metrics, while helping to shape and evolve the firm’s assurance methodology.

This is not a tick-box audit role. You’ll have:

• Greater autonomy and professional judgement
• Lead on the delivery of non-financial assurance
• Ability to carve out your career and the future prospect of leading their Sustainability Assurance offering
• Direct exposure to Partners and senior clients
• Broader work across sustainability, risk and consulting
• Early responsibility for delivery and client relationships
• A clear and accelerated pathway as the practice continues to grow

This role is ideal if you:

• Are ACA or ACCA qualified
• Have a background of non-financial assurance and/or carbon accounting - ideally from a management consultancy
• Experience of leading workstreams and engaging directly with clients
• Are comfortable thinking independently and applying judgement
• Have a genuine interest in sustainability and ESG
• Want faster progression and broader exposure than a traditional audit track
• Knowledge of implementation of ISSA 5000

Experience with ISAE 3000, ISAE 3410, carbon accounting is of great interest too.
