Job Description

The Senior Software Engineer role is a key one for the SG Digital Product Engineering team. The Senior Software Engineer will be working alongside other Senior Software Engineers, Project Managers, QA, Software Architects and Operational Excellence in order to shape and implement the technology and people vision of the team that will drive forward this strategic initiative.

Product Engineering operates a scaled agile operating model. All our development is carried out via feature teams. As such we operate a “T-Shaped” philosophy. Our teams, as a unit, have the breadth of skills to carry out most work items. However each team has its own speciality and depth in a certain domain or area. Similarly our individual team members also bring a depth of particular skills or domain knowledge to the team, along with the willingness and expectation that you’ll pitch in to help your team mates achieve your team’s sprint objectives. As such, you, as a new engineer on our teams are expected to bring a depth of skills to the team, are expected to help others learn those skills, but at the same time have an open versatile mindset to learn new skills yourself and help your team achieve its goals to be successful. By doing so, you’ll be supported in growing in the direction you want to go but also have the opportunity to become a well rounded engineer to help with your future career progression.

In addition, a Senior Software Engineer will be expected to both lead and mentor less experienced developers, actively contributing to their day-to-day activities and training needs.
