Front End Developer (Angular) - London - £65,000

England, London

  • 55000 to 65000 GBP
  • Developer Role
  • Skills: Angular, Front end, Developer, AWS, Python, Git, Angular2+, Angular8
  • Seniority: Mid-level

Job description

Front End Developer - London - £65,00

You'll be joining a small yet well established company who offer a solution where others have failed to do so. The software aims at streamlining the way companies and investment banks work together to raise capital. Their ever growing brand has some massive names on their client books and some outstanding figures to showcase their growth. Within the company it is important to take risks, be humble and most importantly be a driven individual with desire to succeed.

Even though the business is small, it is collaborative and now in fact global. Engineering, product and development teams are all close knit highlighting the culture they have created.

The infrastructure of the business is all based on AWS and therefore any exposure to this would be great. Even the basics when considering DevOps tools such as Jenkins for automation would be good. However, for this role in particular it is essential that you have had commercial experience with Angular. The versions of Angular that you have used is not a deal breaker but 8 is the preference. CSS pre processor experience with either SASS or LESS is also another key aspect.

Now, on to the fun part. Just take a browse at the list of benefits below. Even though there are many more than this, it gives an insight in to the rewards you get!

Benefits

* Competitive salary plus equity package
* Generous home office budget
* Annual training budget
* Flexible working hours
* Annual trips away
* Cycle schemes

&& Many more!
