Wanted: Full Stack Developer

We're always looking for competent web developers who value well-structured code, creative problem-solving, and getting things done without unnecessary faff.

If that sounds like your kind of developer job, we'd love to hear from you.

Who are we?

We are Gecko, a digital agency based in Edinburgh, but we work with clients across the UK. We specialise in Umbraco websites. We've been in the game for 22 years, creating beautifully designed, highly functional, and refreshingly responsive digital experiences.

Our team of developers is small but mighty. We like to move fast, think creatively, and always deliver top-notch work. Through a mix of careful planning, great communication, and genuinely brilliant project management, we've built a team that sticks around – and clients that do the same. Our clients stay with us because we're straight-talking, honest, and ridiculously good at what we do.

What will you be doing?

As a Full Stack Developer, you'll be building, optimising, and maintaining Umbraco websites that look great and perform even better. Your role will include:

  • Developing and maintaining Umbraco-powered websites with .NET (C#).
  • Writing clean, scalable, and maintainable code that plays nicely with our front-end web developer team.
  • Working with SQL Server, Azure, and modern dev tools to keep everything running smoothly.
  • Collaborating with designers, project managers, and clients to bring ideas to life.
  • Troubleshooting, debugging, and generally being a tech wizard.
  • Keeping up with best practices, emerging tech, and Umbraco updates.

What are we looking for?

We are a strong, talented, tight-knit team who support each other effortlessly, but we need backend developers who can hold their own and use their initiative. Below is some more about what we are looking for in the ideal candidate.

Be responsible

You take ownership of your work

While our team of developers is collaborative, we're looking for someone who can pick up a project from start to finish and work independently with strong problem-solving skills. Of course, "independent" doesn't mean "alone" – our Technical Lead is always on hand to provide support. We also use Slack for quick questions and chatting with our colleagues in Chester, Bristol and Portugal.

Embrace variety

You enjoy different types of projects

Our work varies between creating new websites and updating existing ones. Some projects are quick turnarounds; others take months. As a Full Stack Web Developer, you'll integrate third-party services and support clients long after the big jobs are done. You'll work on diverse development projects, using your development skills across web and mobile development. Every week brings something new, so we’re looking for someone with a genuine enthusiasm for web application development and the development of software - from writing clean code to exploring the latest industry trends.

Communicate effectively

You can translate what you do

All members of our team have client-facing moments – whether it’s pitches, meetings, training, or support tickets. We need someone who can explain technical work in simple terms, translating complex technical skills into clear, actionable insights. You'll be working across various digital platforms, ensuring seamless integrations and optimising the online customer experience. This ability to communicate effectively is one of the reasons why our clients stay with us for years.

Get the big picture

You can see beyond your role

We need a Software Developer with strong experience who can explain technical concepts in simple terms. Whether you're on a client call, writing a support ticket, or demoing a feature, clarity is key. You'll also collaborate closely with our design team to ensure seamless integration between development and user experience.

What’s in it for you?

We believe that great work comes from happy, motivated people. Here’s what we offer:

Hybrid Working

A mix of office and remote work to suit your style.

Flexible Hours

We care more about great work than watching the clock.

A Competitive Salary

We know good talent deserves good pay, we offer a competitive salary and time for professional development.

Personal Development

We invest in our team, whether that’s training, certifications, or learning new skills.

32 Holidays Per Year

Generous holidays and no mandatory days off (other than bank holidays; 2 at Christmas and 2 at New Year, but who wants to work then?).

Pension

Gecko staff pensions are in line with the Government's Auto Enrolment schedule for a business of our size.

Childcare Vouchers

Save up to £933 per annum - vouchers can be used with childminders, nurseries, play schemes and extended school care.

Bike Storage

If you prefer to cycle to work, there's secure bike storage, heated lockers and shower facilities.

Gym

All staff have access to the gym in Orchard Brae House, just a floor below us – perfect for a lunchtime workout or post-work session.

A Fun, Friendly Team

We take our work seriously, but never ourselves.

Exciting Projects

No two days are the same, and we work with some fantastic clients!

A Modern Office Space

Modern, comfy seats, breakfast bar, unlimited tea and coffee, and a lovely atmosphere!
