Job Description

This role will suit a principal software developer with expertise guiding and contributing directly to cloud software development with AWS or Azure. The data-oriented platform and pipeline at hand is central to a suite of applications with a positive impact on global sustainability, and this is a prominent role with responsibility and reward.

You will have a principal engineer's ability to address the finer points of architecture, consider the ramifications of far-reaching decisions, collaborate with stakeholders, and cultivate and apply the right elements of modern good practice and standards. Through such actions and direct contributions you will play a key part in shaping platform capabilities and effectiveness.

You will also bring:

  • Prior experience designing and successfully delivering complex, high-quality enterprise and/or cloud solutions, from technical domains such the scientific, engineering and/or industrial sectors.
  • Significant skills with C# and modern .NET, creating elegant designs, tracking the evolution of the language and selecting the best elements to incorporate.
  • Experience with AWS or Azure as a target platform, containers, and potentially cloud native approaches, Kubernetes etc. Ideally (not necessarily) this may include specific knowledge of vendor offerings and appropriate architectures and patterns for those offerings.
  • A deep understanding of cloud-compatible architectures (such as microservices and SoA), RESTful API design considerations, and ideally, a good awareness of security and authentication considerations (OAuth is relevant).
  • A strong academic track record including a good technical degree and top A-level grades or equivalent.

The company offers a multi-cultural environment, a focus on sustainability, and a top package including a highly competitive salary, enhanced pension and holiday, hybrid working several days per week, and a host of career and skills development options in addition to tailored package elements.
