We’re looking for a Principal Software Engineer to join our digital product delivery function. Red Badger delivers high quality digital products using a lean delivery process and multidisciplinary, cross-functional teams.

The Principal Software Engineer has deep technical expertise and specialises in solving complex problems that arise in the development of digital products. This role plays an influential role, supercharging a team and elevating those around them. You are a senior practitioner who works on influencing technology adoption to enable Red Badger value propositions. You will work closely with Technical and Delivery Leads, providing expert input into the technical direction of a client project, ensuring that due consideration is given to ambitious technology choices and best practice. You will consult with our clients on your specific areas of technical knowledge and help them understand the benefits of new technology and industry innovations. 

There is also an internal quality aspect to the role which involves contributing to the elevation of technical standards across Red Badger, and how we represent ourselves externally to the industry.

Hands-on work is expected to be the majority of the role - demonstrating by doing, but also be prepared to get involved in thought leadership, sharing your knowledge with other badgers, and high value consulting activities.

The Principal Software Engineer works across a range of account sizes but will be equally comfortable providing high value consulting services in a focussed technical audit as they are supercharging a cross functional product team who are being brought up to speed on new technologies as they deliver.
