Pros

During my time at QuantSpark, I appreciated the well-organized technical documentation, structured policies, and the company's commitment to training and self-development. The talented and hardworking individuals contributed to an engaging work atmosphere, and the projects were interesting, addressing valuable problems. While my experience had its positives, every workplace has its unique dynamics.

Cons

While the training provided was good, the company lacked sufficient opportunities for professional growth. Team structures were either too large, leading to insufficient work for everyone, or too small, resulting in excessive workloads. The annual review focused on irrelevant issues to explain the lack of promotion or a salary increase, such as language proficiency (as a non-British individual) and public speaking skills, which were not pertinent to my role. Work-life balance was challenging, with staying late being praised, and a subtle expectation to work beyond the standard hours. Bi-weekly maintenance work scheduled after hours was uncompensated. The company proved unreliable, as they changed the remote working policy after hiring, and there were unexpected layoffs without ample warning. Unfortunately, my trust in the company eroded, despite the presence of talented individuals still contributing to the organization.

Pros

There are a lot of emotive reviews on here, and while I can understand why people feel how they do, I think it is unfair to lump all problems onto the management/leadership team. I, for one, had a good manager/department lead who did their best to support in what was a difficult working environment for all involved. There are some people in the company who truly care about others and want to do good work, sadly most of these have felt no choice other than to now leave. I worked on some interesting projects where I was given a good level of ownership to develop my skills and ultimately move on to somewhere better suited.

Cons

It is amazing how much a company can change in such a short period of time. When I joined QS there was a buzz about the company and some exciting and interesting projects. In the past year almost all people with significant skills or experience have left meaning a chaotic and unsupportive work environment.

Pros

Quantspark has one overwhelming advantage, and that is, as noted by other reviews, its people. During my whole tenure the hiring was nothing short of exceptional and you will be working with a very talented and motivated bunch (keeping hold of them seems to present more of a challenge, but more on that later). The colleagues were a big part of what made working here so fun. If you want to get a lot of experience quickly, this is absolutely the place. You will work on a wide array of projects with a high degree of autonomy. This is an excellent way to learn. You will be encouraged to try new technology and experiment with new things, especially those with an AI flavour. These are material benefits that you would be hard pressed to get elsewhere. You will need to be comfortable with going outside the typical boundaries of your role and as such you will experience a very wide variety of project and sector. This advantage cannot be overstated and is critical to the value proposition of working at QuantSpark.

Cons

For me, the biggest drawback was remuneration. If you are early in your career or transitioning into a new role the wages are fair, however once you attain more seniority a clear gulf emerges between QuantSpark and the wider market. Projects are often accepted with 'ambitious' timelines. This leads to stress and prevents engineers having the breathing room to build truly great products. The company pivots too frequently. Communication from upper management can occasionally feel impulsive, making it hard to settle into a long term direction.
