The past month, we’ve done deepdives in the newsletter on what a senior software engineer is at Big Tech, and at scaleups. This issue looks at two companies from the 15 covered in those articles: we cover Wise and Amazon.
Wise – formerly Transferwise – is a publicly traded Fintech, valued at $6.5B at time of publication. The company employs more than 5,000 people in 17 countries. Its biggest engineering hubs are London (UK,) Estonia, Austin (US,) Budapest (Hungary,) and Singapore. The company not only makes its engineering levels public, but also its compensation ranges across all regions. Here’s how levels and compensation line up:

Harsh Sinha, the CTO of Wise added additional context to the above numbers:

We put a lot of emphasis on communication and prioritization and the ability to unblock yourself or your team – this comes on top of the programming and design skills.
A ‘typical’ Senior Engineer to me is someone who seeks out difficult problems, and has the skills to solve them in a sustainable way. They strive to build things fast, but also know when we have to slow down to go faster.”
Amazon’s SDE3 level maps to what the industry commonly refers to as “senior engineer.” A summary of this level’s typical expectations:

Amazon’s SDE3 definition is closer to what is considered a “team lead” or “tech lead” role at many companies, and so I view this SDE3 role as being at the upper end of a senior engineer definition. Amazon emphasizes a few different things at this level:
