As a Software Development Engineer 2 you are in a mid-level Individual Contributor role at Tesco. Engineers at SDE2 level will continue their career development and show potential for an SDE3 role. SDE2 is a stepping stone towards SDE3, rather than a career destination in its own right. At this level, your impact reaches across a team, and you provide technical leadership of medium to large features. You are starting to produce your own work by understanding the problems that the team faces and are beginning to support other engineers with their own delivery and development. You prioritise sharing your skills and knowledge. You also prioritise quality of work, helping your team to continually set the standard. You understand and apply best practice within Tesco and across the industry. 

My impact reaches across the team in which I work. I provide technical leadership of medium to large features, participating in their design and taking accountability for their delivery. I am comfortable implementing and shipping end-to-end stories and am starting to understand the deeper problems in my part of the business. I am likely to be considered an expert in a specific part of my domain. This is the first level at which I do more than complete the work that’s been assigned to me: I am starting to build and prioritise my own work by understanding the problems my team faces and proposing, implementing, and delivering solutions to them. I am aware of the short-term and long-term goals across my product. I work within my team, utilising data driven decision making techniques, to encouraging optimal outcomes whilst accepting appropriate trade-offs. I am comfortable both supporting other engineers in their delivery and taking the lead on major components or small services as appropriate. At this level I display a degree of ownership for the work conducted by the team and am experienced enough to know when I need support. I am able to identify risks and raise these as appropriate. At this level I am beginning to support, coach, and mentor those around me. As junior engineers join the team, I am assisting them through their onboarding process and leaning on my past experience to help get them up to speed. Whilst I may not formally be a mentor for other engineers, I am someone that individuals across the team will come to for advice and help. I prioritise sharing skills and technical knowledge across my team. I contribute to the raising the quality bar of my team’s codebase, both in the code that I produce and by helping to peer review code written by other team members. I proactively provide constructive and useful feedback to other team members on their code. I have a good understanding of best practices across the industry and of Tesco architectural standards. I make sure to put these principles and standards into practice when completing my work. I am aware of the best testing and deployment strategies in the industry and have a view on the suitability of implementing these within my team. I am comfortable working in a group context and am capable of communicating technical concepts to key stakeholders.
