Jobs

This job is all about working with the local third and public sector to engage with local people to create change. To make this happen, the role has three key bits to it:

• listening to what local people want (gathering the insights);
• building a vision for a ‘better way of doing things’ (planning to make change); and
• getting stuck into supporting our clients and wider team to make things happen (doing the stuff we’ve planned).

Each day you’ll be shaping and delivering Capacity’s current and future projects, managing expectations, excitement, and priorities - keeping a smile on your face and a spring in your step. Even on the busiest of days, our Designers and Doers remind themselves why they’re in it, finding the get-up and go to make public services, people services.

Alongside delivery, you’ll contribute to business development, client relationships, and the continued evolution of our Homes and Missions model.

The to-do lists you write and the skillsets you engage will vary hugely, one day you might be working on recruitment strategies for social workers, the next on service design for family early help, and another strategy planning for a primary care team. When job descriptions say ‘no day is the same’ that can often feel twee, at Capacity - it’s a promise.

You’ll spend your time being proactive - delivering on our promises to clients and local people, whilst staying ready to catch any ‘off-project’ work that might need sorting along the way. You’ll support us to get new clients on board but also play a key role in further engaging our existing ones, making sure they continue to feel connected to Capacity and proud to be involved in the work we’re doing.

The projects we deliver are often complex, and things won’t always work out. For that reason, you’ll be open and honest about what’s working, what isn’t and where you might need extra support. If you’re considering this role it’s really important you aren’t afraid of making mistakes or asking for help.

This role exists to help Capacity change how public services work for people, not just deliver projects. You’ll lead exciting work that brings together communities, public services, and partners to create meaningful, equitable change. You will operate at the intersection of discovery, strategy, design, and delivery, holding complexity, shaping direction, and helping others act with confidence in uncertainty.

You’ll be accountable for both what is delivered and how it is delivered: ensuring the work is grounded in lived experience and evidence, co-produced with people and partners, and delivered with integrity, pace, and care. Alongside delivery, you’ll contribute to business development, client relationships, strategic direction, and the continued evolution of our Homes and Missions model.
