As a Consultant, you will:

• Take ownership for the end-to-end delivery of workstreams within client projects, managing your own time to meet deadlines while balancing non-project commitments. At the Senior Consultant level, you will be responsible for delivering entire projects, setting interim steps and deadlines, acting as the main day-to-day client contact, and keeping Directors informed of progress and issues.
• Lead quantitative and qualitative analysis, determining the approach, cross-checking conclusions against the underlying data, and testing them with colleagues before they reach the client.
• Produce client deliverables to a high standard: Word reports, PowerPoint presentations, Excel models, and dashboards that follow the Sirio visual identity, carry no errors, and are structured clearly.
• Present project updates and findings to clients, including senior stakeholders. At the Senior Consultant level, you will own the presentation end-to-end, anticipate the questions clients are likely to ask, and ensure the wider team is prepared.
• Build in-depth knowledge of GB energy networks, the wider gas and electricity value chain, and the energy system transition, together with the regulation that governs it, particularly the RIIO framework and Ofgem consultations, decisions, and incentive results. You will be expected to form a view on how regulatory developments affect our clients and where they create opportunities for work.
• Support the firm's commercial activity by identifying client needs and sales opportunities, developing proposals and other client-facing materials, and conducting market research. At the Senior Consultant level, you will turn those opportunities into specific offerings and deliverables and maintain direct relationships with client counterparts.
• Contribute to Sirio's intellectual property by writing articles and research, supporting the development of tools and products sold to clients under subscription models, and disseminating our thinking through our website and social channels.
• Support the development of colleagues by sharing knowledge and experience, reviewing written work, and giving constructive feedback, and take responsibility for your own development against an agreed performance development plan.
• Contribute to the growth of Sirio as a business by proposing and running internal initiatives across skills development, employee wellbeing, and productivity. You will also take forward a side project of your own at the intersection of your interests and Sirio's strategy.
