Hi. We are headhunting technical people with real potential - people who want to be challenged to produce work of the highest calibre.

Maybe you don't feel like a Rockstar Software Engineer...that's not the criterion, so no problem. We know how to dig and identify real talent.

Join us at Cellusys, and along with your team, you'll have end-to-end responsibility. You'll be involved from the stage of understanding requirements, through to architecting, developing and installing the product. We'll give you this breadth of responsibility because it makes Cellusys a good place to work; you'll be part of the team from day one, you'll get the insights it takes to make the product better; you'll have the ability to evolve the product.

This is how we enable our engineers to make products that are light years ahead of the competition.

Some of our interns' stories

"I think what makes the DLX programme really stand out is how practical it is. I believe the best way to learn is by doing and Cellusys really encourages that. I've learned a lot of cool, new technologies and everyone at Cellusys is really approachable and friendly - if you ever have a problem there's always someone there to give you a hand."

Cellusys Intern 2015 (DCU CA 2016)

"The first day I arrived at Cellusys, I was made part of the team immediately and was creating products that would be used by all employees. You are involved in every part of the development structure from designing, to coding, to testing and deployment. If you have the will to learn be sure to apply, I guarantee you won’t regret it."

Cellusys Intern 2015 (DCU CA 2016)

"A lot of my friends were talking about Cellusys so I applied to the DLX programme, did an interview and got the internship. I've learned a lot of cool technologies that have helped me with both my college work and side projects. If you're looking for a good challenge and are willing to learn, definitely apply to the DLX programme."

"The training here really is good and the fact we're always using the latest stuff... like in some other companies they're using technology that's five, ten years old. We use the latest and greatest on every new project."

Software Engineer, DCU CA 2014

"When I solve a big problem - that feels really good. The greatest thing is our teams. We work very well together; talk through a problem and solve it more easily; our brains are more than a sum of the parts."

Software Engineer, DCU MSSF 2006

"I came back to Cellusys after doing my internship. I'm glad I did. Here things are constantly evolving - the products, the technology. We're always working with the best technologies. You won't get bored, that's for sure."

Software Engineer, DCU CA 2013

"It's always challenging in here; always evolving. I came back from maternity leave and everything had changed - I had a new programming language to learn; everything. The sense of achievement is immense. Everybody learns a lot - whatever level we're at."

Senior Solutions Architect, UCD BComm 1998

"Customers really tend to like us because we're willing to engage. I think it's a culture thing - we love it here so we take real pride in the job. Like when something needs doing there's not this long drawn out process - we just get on it and get it done."

Technical Architect, DCU CA 2009

"Cellusys is definitely a lot more technical - that's one thing that attracted me to Cellusys - very engineering focused. You see a lot of internal politics in other places. Here, it's the end goal we're focused on; clean, effecient code and well-engineered products."

Senior Software Engineer, DCU CA 2011
