Senior Frontend Engineer

Senior Frontend Engineer

Permanent, Madrid

We are working with a 12 person start-up based in Madrid who have developed and patented a state-of-the-art TCP stack and a transparent gateway, which is the basis of their product. The product is a network node that they sell to mobile and fixed-network carriers, corporate clients and CDNs, helping to significantly accelerate TCP traffic whilst also allowing the most sophisticated bandwidth management and network visibility. Having recently secured their first round of financing, with a 1.5M€ investment from a leading Spanish venture capital, they have become one of the most successful network optimisation companies world-wide, with over 400 network providers using their product.

What to expect:

With 3 Frontend Engineers already hired and 4 Backend Engineers also part of the team, we are looking for an additional person to join either side of the fence. Naturally, as the Backend team grows, the Frontend needs to do so in tandem. In order to stay up to date with competition, there needs to be continuous optimisation and feature development, which is where the Frontend team will come into play, as the graphical interfaces, data related graphs and customer facing dashboards need to consistently accessible. You will be working alongside a team of Senior Engineers, since the company prefers to build robust and sophisticated software with a team of veterans before branching out and hiring up and coming talent.


  • A salary of €60-100k depending on experience
  • 100% remote options, with an office in Madrid
  • A permanent employment contract
  • Exposure to working with high amounts of data in an exclusively Senior team


  • A minimum of 6 years working experience
  • Experience working with Javascript and React
  • Exposure to working with components such as a Bootstrap
  • Familiarity with Linux systems
  • An affinity with UX/UI
