We’re on the lookout for a UX / UI Designer

It’s a chance to be part of a growing, friendly team trying to make a positive difference fight the climate emergency.

What we’re after

We want team players who’ll integrate well, pitch in to help others as needed, and make being at work at least something approaching fun from time to time.  We’re a small but growing business, and you’ll need to be self-motivated, completely trustworthy and able to manage your own delivery to hit milestones.  

You’ll be flying the flag for us to partners, so being personable and a good communicator will be important. Being a bit “eco” definitely isn’t going to hurt either! 

What we’ll be asking you to do 

You’ll be working alongside our growing digital team to help create, test and launch new products and applications including mobile, tablet and we based tools. You’ll work closely with front and back end developers that are part of our internal team and our suppliers. 

We’ll want you to work with the Sero Customer Experience, Branding and Technical teams to ensure that you capture and understand all of the requirements for our users. You’ll have the full support of the Sero team in generating new ideas and refining designs. We’re happy for you to propose the tools that you need to use to get the job done. 

What about skills & qualifications? 

  • You thrive in a collaborative startup environment and you’re always willing to learn and understand the problem we’re solving.
  • A keen interest in sustainability, renewable energy and climate change is beneficial.
  • A degree in Graphic Design, Creative marketing and/or suitable experience in the role of around 2-3 years as a minimum, working with mobile and native applications. You’re used to working with sketches, prototypes, wireframes and process flows.
  • You’re an expert in the Adobe design package including Photoshop, illustrator and Indesign and proficient with other tools such as Figma.

What’s in it for you? 

Diversity We actively look to reflect the variety of our world and welcome the widest diversity of applicants – it’s only your talent and experience that matters.

Contract This role will be a temporary contract initially with a minimum 6 months term, however there is an opportunity for it to become permanent as our business grows.

Working Hours We’re looking for about 37 hours per week for this role – what would generally be called “Full Time” however we’re also open to applicants looking to work part time. How that breaks into days or a working pattern is up to you.

Working Times Our policy allows working anywhere at anytime, ultimate flexibility. We’d like at least some of your working hours to be coordinated with other internal and external team members to ensure we’re being efficient and communicating effectively. We think work should fit your lifestyle, so you can work when you can be most efficient!

Location We’d like to see you in our Cardiff city centre offices (unless we’re locked down) often enough for you to be able to do the job effectively, integrate our ethos and work with the team. But otherwise, we’re focused on you doing the work, not where you choose to do it. We’re fully set up for virtual working!

Contract Value We’ll be competitive (of course). This also depends on what we agree between is your preferred weekly total hours.  

Perks You’re helping save the planet! 

Who are we?

Sero was founded to make a connection between homes and energy, and to use technology to make both these easier and smarter together. We do this to save our customers money and to save them time, but we also do it to save our planet. To tackle the Climate Emergency, we provide clever energy services that automatically reduces the carbon footprint of the homes we run. To do this, we work with other home builders and landlords to help them understand what to do with their buildings to achieve this. We also try and lead by example, so through our sister company Sero Homes we build true zero carbon homes, set in ecologically vibrant spaces and places (there’s a and Biodiversity Crisis too!), so that our homes help to build a community. 


If you think we’re a match, please get in touch! We’d like a C.V., but send it with a covering note too please that tells us why you’d be our perfect fit for our team. Your note can be a letter, email, video snippet, go crazy, give us a little bit of your character…
