About the role

Responsiv develop solutions for our customers, and develop software components to accelerate projects and support our own product strategy. This role is a hands-on software development (general programming) role that requires exceptionally strong technical and programming ability coupled with the desire to learn new languages, products, techniques, and solution areas on an almost continual basis. Reporting to the head of consulting, the role will be attached to projects as needed, and expected to work as part of a development team or solo on customer site or at the Responsiv offices in Bracknell.

The role requires a good foundation in software engineering, including design, development, testing, and troubleshooting. It requires the ability to work as part of a high performance team, and to quickly get to grips with technologies that are emerging, or that use concepts that are new to you as an individual. The need to maintain an understanding of what is happening in the main Open Source projects, and with proprietary software (IBM, Microsoft, and others) used by Responsiv is paramount.

  • Lead software component design and development
  • Learn and develop components using specified technologies, for example bash script, javascript, Java
  • Support pre-sales proof of concept (POC), and proof of technology (POT) projects, as well as presenting as required
  • Documentation describing software components and solutions to other technical readers and to non-technical audiences

Responsiv specialise in enterprise automation and connectivity. This means that we are always meeting new products that we need to learn and connect with, and having to create small components that solve problems that are otherwise major inhibitors to our solutions or customer satisfaction. For example, we may need to integrate to a bespoke DIY system to a rules engine, exposing rule editing to an intranet site. We also develop fully specified business solutions that take many man-years of effort.
