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.

Permanent: We’re a growing SME and see this role as a permanent member of our growing team. We’ve got lots of plans up our sleeves for exciting new things!

Working Hours: We’re looking for about 37.5 hours per week for this role – what would generally be called Full Time. How that breaks into days or a working pattern is up to you.

Working Times: Our policy allows working anywhere at any time, 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 center offices 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!

Salary: We’ll be competitive (of course). This also depends on what we agree between us your preferred weekly total hours.

Perks: You’re helping save the planet!

Also, 6% pension contribution from us; healthcare with family & dental options; electric vehicle scheme; equity scheme; cycle to work scheme; training & development support of course; office fruit bowl & refreshments!

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

We’re looking for someone to support our existing finance team in the smooth running of the finance function at Sero. Some of the tasks will include, but not be limited to:

  • Posting and raising invoices
  • Management accounts prep and monthly journals
  • Year end accounts prep
  • Raising PO’s/SO’s
  • Bank reconciliations
  • Supplier payment preparation
  • Credit control
  • Monitoring the accounts mailbox
  • Checking expense claims for accuracy
  • VAT calculations on mileage claims
  • Preparing VAT returns
  • Preparing monthly intercompany recharges

What about skills & qualifications?

Ideally we’re looking for someone with at least a year’s experience working in industry, although if you’re coming straight from practice and think you could hit the ground running then we’d love to hear from you.

Minimum AAT (or equivalent) is a must. We’d be happy to support you through further study as well.

Experience of Microsoft Excel and Accounting Software (Xero, Sage, SAP, Netsuite etc) is essential.

You will also have excellent numeracy skills and a strong attention to detail.

One of the main qualities we are looking for is initiative. We are a small team and a rapidly growing business where processes are still being developed. The ability to manage your own work load will be very important.

We would also like to see someone who is great at communication, you will be encouraged to have discussions will everyone at Sero at all levels, as well as external advisors.

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…
