Anna – Operations Controller

Joined 2011 – present day

“I joined GMSL in 2011, not quite straight out of university as I had held a couple of positions beforehand, but the gas and power industry was completely new territory for me. It was challenging at times, but the provided training and the team’s support enabled me to quickly become an efficient and knowledgeable operator. In 2016 I became a shift leader, and on top of the usual day-to day operations, I manage my own team, am involved in training, and get to meet some of our clients.

Probably one of the biggest challenges when joining is the shift work and long hours. It has its ups and downs – occasionally, I would struggle to stay awake for the last hour or two of the nightshift – but I got used to this fairly quickly and now enjoy the long periods of time off, days off during the week, and the general flexibility of my work hours. What also makes the long hours easier is the amazing atmosphere in the office; everyone is very friendly, there is always time for tea, some cake (or as past experience taught me, a LOT of cake), and a fun conversation.

Over the years I have worked at GMSL, I have not only grown on a professional level, but also personal one; ready to take on any challenge, and do so eagerly.”

Gary – Operations Controller

Joined 2006 – present day

“I joined the 24/7 gas operations team with very little background knowledge about the industry. It has more than doubled in size in my time here, whilst still managing to maintain an informal but professional atmosphere. There are regular social events organised including bowling, paintballing and go-karting to name just a few.

Working a mixture of hours has its challenges, but is compensated by generous time off. I enjoy the non-routine nature of the job, no two days are the same and you are encouraged to take on responsibility at a relatively early stage. Working night shifts can be tiring but it certainly feels great to be going home in the morning when the vast majority are on their way to work!

I now lead a shift team which has given me additional responsibility. It requires a significant amount of prioritisation and multi-tasking, but the great thing is that there is always someone around to help if you are a little snowed under. I’d recommend the role to anyone who has a positive attitude, is a good team worker, and wants to work in a fast-paced and fascinating industry. ”

Lee – Product Owner (formerly Operations Controller)

Joined 2009 – present day

“I started at GMSL in 2009 as a member of the operations team straight out of university. Whilst the learning curve at GMSL was steep and challenging I never felt out of my depth and was supported well by my team and the training staff. If I was ever in doubt as to the correct course of action to take, or unsure of a new procedure, a colleague was always on hand to help me find the right solution. From that day to this I would say that the feeling of being a part of a team has been the defining part of my experience at GMSL.

Working on the 24/7 shift had its ups and downs, I may have found myself a little bleary eyed the morning of the first day shift back after a run of nights, or flagging a little at five o’clock in the morning towards the end of a night shift, but at GMSL there’s always someone making a round of tea or sharing a joke to keep spirits up.

In 2014 I was made a shift team leader responsible for operations carried out by my team over the 24/7 shift. In this leadership role GMSL encouraged me to set goals and manage my own small team’s development alongside our day to day work. I was encouraged to not only supervise but was also given a voice to influence and be a part of the planning of the procedures the team should follow. At GMSL I have always felt that my voice is being heard and that my opinion has been respected.

Recently I have started working on GMSL’s software team as a Product Owner. In this new role I use the knowledge and experience gained in my time working on the operations team to help guide the development and improvement of GMSL’s software. During my time at GMSL I have repeatedly been challenged to learn new things, and given the opportunity to take the lessons and knowledge I have gained to solve new problems.”

Alex – Operations Controller

Joined 2011 – October 2017

“I joined GMSL in 2011 after being referred by a friend, but I still knew very little about the job. Through my time at GMSL I have gained real insights into how the gas industry works as well as building good work practices such as; working to deadlines, professional communication with clients and other companies within the industry, and working effectively as part of a team. Since becoming a Shift Leader in 2016, I have also learned how to co-ordinate a team in an office environment.

I find the nature of the work engaging and although it took some adjustment, the shift pattern and long hours have become more familiar as time passed. The friendly office environment, large amounts of time off – combined with a wage that allows you to make the most of it – more than compensate for working nights. For me personally it meant that I have been able to spend more time with my daughter as she has grown up.

Shift work might not be for everyone but I have enjoyed my time at GMSL and learned a lot. I would recommend the role to someone who has a good work ethic and enjoys working as part of a team. The knowledge, experience and good practices that I have acquired through working at GMSL has allowed me to develop my career, as I am now moving on to another company in the gas industry.”


Jenny – Software Tester

Joined 2009

“I’m responsible for finding problems with the software before the customer gets it. This could be a problem with the design, it could be a problem with the code, it could be a problem with the database design. A developer thinks about what should happen. A tester thinks about all the things that shouldn’t!

I test new versions of the software to destruction in order to prevent problems reaching the customers, doing all the things the developers and business analysts have assured me ‘the users will never want to do’. Because I know it’s going to be the first thing the user does.

I write automated tests using a variety of tools, some written by other people, some by me. I only want to spend so much time button clicking through the same process every time the system gets rebuilt. If it’s going to be tested often, then I automate the procedure.

I enjoy my job at GMSL because I get to use my brains and follow my interests in IT and business. I might talk to users in the morning and code improvements to the test harness in the afternoon. It’s varied, challenging and fulfilling, making working life easier for the users. GMSL encourages me to learn new skills and I get sent on training courses with the best software testers in the world. We all get to say what we think and contribute to the development of new software.”

Thomas – Software Developer

Joined 2011

“I came to GMSL straight out of university, with no formal programming experience, but found that they were more interested in my enthusiasm and potential than what I could already do.

I spent the first few months working through exercises and projects to get up to speed in the various languages and concepts that I’d need. Some of it was building on my previous informal experience, filling in the gaps and explaining the areas I was already familiar with; but much of it was entirely new. Once I’d finished the training projects I started working on a real product by fixing bugs and adding small features. After a year of progressively more challenging work I knew my way around the majority of the code and felt comfortable in my role.

Throughout my training I was encouraged to ask questions whenever I didn’t understand something I had read about. I was worried that there’d come a day when I was expected to ‘know everything’, but even now I’m still asking colleagues questions and checking whether someone on the internet has already provided the answer. With new techniques and technology coming into use all the time, this seems to be quite normal and people here are happy to help where they can.

Although, as in all jobs, some days are more stressful than others, I enjoy my time working here. The people are friendly and we regularly head out to lunch together, sometimes getting together after work for games or bowling. The work is usually interesting and with flexible hours I’m able to do it at the time of day that suits me best. Not only this, but when the day is over, assuming that I didn’t decide to work from home that day, I never have to take my work home with me.

When I was looking for jobs I wanted something challenging but interesting and somewhere serious but friendly. I specifically didn’t want a high pressure, highly competitive job with constant unworkable deadlines and a culture that promoted staying late every evening.

I believe I have found what I was looking for.”


Paul – Software Developer

Joined 2009

“Since joining GMSL I’ve worked on a handful of products, ranging from about 1,000 lines of code to about 500,000. We mainly do C# and SQL development, but there’s bits of everything from VB6 (rarely, thankfully!) to XSL to JavaScript, and some other things besides. The software we write is very specialist – some products are licenced to fewer than ten customers – which means there’s plenty of scope for thinking outside the box, and for solving problems that you can’t just Google.

It’s a great place to work – lots of talented and friendly people, a relaxed atmosphere, and no red tape except for the occasional running repair in the server room. Dress code is jeans and t-shirt, and the only people still working come eight o’clock at night are the ones who start at lunchtime. And the 24-hour operations team, obviously.

I guess the best endorsement I can give for working at GMSL is that I’m still here, as is more or less everybody else who was here when I joined!”
