Technical SEO - as I use the term - describes tasks like the following:
1) Performance optimization (One of the most important tasks)
It's basically me telling my clients that their Devs were right all along and that they have to improve their site's speed
2) UX feedback (Help in terms of usability and user experience because unusable sites will rank much worse on Google)
This is basically me telling my clients that their "fancy" 200.000 $ redesign will never rank in Google and that they have to use a "boring" design. (Their Devs were right again ...)
3) Improve internal linking (Prioritize important pages with high search volume, deprioritize less important pages)
More complicated, but this is one of the most important tasks for "big" websites (e-commerce, news, travel, ...) and one of the biggest levers to improve rankings
A lot of other related tasks are not that easy to explain for me in text (I am a non-native English speaker and this comment already took me 20 minutes up until here ...) and my guidelines vary from website to website.
But, essentially, I help clients to adhere to web standards and optimize their websites for their users. The last "spammy" backlink I build for a project other than my side-projects (experiments) was probably more than 5 years ago ...

4) manage URL-corpus
One of my clients' had every single article of his indexed on more than 5 different URLs (eg. https://www.website.com/correct-url, https://www.website.com/correct-url/, https://www.website.com/correct-url?preview, https://www.website.com/correct-url/?preview,https://www.web..., https://www.website.com/?1234). Each URL hat internal links pointing to it, so the domain's "power" was split through hundreds of thousands of URLs. Google hates this and traffic exploded after fixing this.
