At Optimised, we help organisations take control of energy, utilities and sustainability performance - reducing cost, carbon and operational complexity at scale.
We’re looking for a Senior Sustainability Consultant to lead carbon accounting and climate disclosure projects for our clients, from the first conversation through to delivery and beyond.
Based in our Bristol office, you’ll join our Net Zero Advisory & Reporting team, working alongside Sustainability Consultants and Data Analysts. You’ll run your own projects from start to finish - shaping the scope, managing the commercials and making sure clients get work they can rely on - while guiding the day-to-day work of more junior colleagues.
You’ll be trusted to work independently and make sound decisions, and you’ll know when something needs to go further. Just as importantly, you’ll help clients understand what their carbon data means for them and spot where else we can help.
If you want to lead meaningful climate work, see the real difference it makes to clients and help shape how our practice grows, we’d love to hear from you.
We know great candidates don’t always tick every box. If you’re excited by this opportunity, share our purpose and believe you have the capability and ambition to succeed, we encourage you to apply.
Why join Optimised?
We’re not just another energy consultancy.
As a certified B Corp, we combine commercial performance with genuine environmental impact - helping organisations reduce energy consumption, control utility spend and accelerate decarbonisation.

Our solutions span:
- Utility Management

- Own every stage, from setting boundaries and collecting data to calculations, quality checks and final reporting.
- Use carbon accounting software to manage client data, calculate emissions and produce clear, accurate outputs.
Climate disclosure and net zero
- Lead climate-related disclosure work based on the TCFD framework and the UK Sustainability Reporting Standards (UK SRS) that are replacing it for listed companies, including climate risk, scenario analysis, and metrics and targets.
- Contribute to net zero target setting and pathway work, including Science Based Targets initiative (SBTi) submissions.
- Support our Reporting team with SECR, and support our REGO, RGGO and wider renewable advisory services.
Project delivery
- Run projects from mobilisation to close, including planning, resourcing and timelines, and deliver the agreed scope within the agreed costings.
- Turn client requirements into a clear delivery plan, keep clients updated on progress and present outputs in a way that shows what they mean for the client.
- Raise commercial, delivery, quality or client risks early with the right person, with a clear view of the options.
Sales and commercial
- Lead proposals and client conversations, with support, from pre-sales through to contract - understanding what the client needs, shaping the scope, writing proposals and presenting pitches.
- Manage the commercial performance of your projects, tracking revenue, days spent and gross margin, and acting early on budget pressure or scope creep.
- Spot opportunities to support clients further across the Optimised portfolio.
Developing others
- Oversee the day-to-day work of more junior colleagues on your projects, giving clear and regular feedback.
- Mentor less experienced colleagues and contribute to internal training and knowledge sharing.
Growing our practice
- Produce thought leadership, such as papers and webinars, with our Sales and Marketing team to help educate the market and our clients.
- Stay up to date with climate policy, carbon accounting and disclosure standards, and keep our climate policy monitor current.
