This month turned 7 years since I joined Uber. Since it will be the last (a bit
|
||||
more on it in the next paragraph), I though it's good to write a retrospective
|
||||
on how it looked like.
|
||||
|
||||
On 2022-09-07 it was announced that Uber engineering site will be shut down on
|
||||
2023-06-30. Whoever is willing to relocate are welcome to do so. The rest will
|
||||
be laid off. The "easiest" offices for relocation are where our organization
|
||||
is: Aarhus, Amsterdam, Seattle, New York, Sunnyvale and San Francisco. In my
|
||||
case, I have a good life in Vilnius and want to keep it that way. So my days
|
||||
are numbered.
|
||||
|
||||
Note that this started *before* the "layoffs of 2023" in the industry. Given
|
||||
the conditions (9 months notice!), it does seem like a strategic move, not a
|
||||
cost-saving one.
|
||||
|
||||
Chronological summary of my employment and projects at Uber:
|
||||
|
||||
- 2016-02-01: joined in Amsterdam, Marketplace Topology team.
|
||||
- 2016-10-30: moved to Vilnius, Lithuania. Joined "Foundatoins Platform" team
|
||||
(probably it had a different name back then).
|
||||
- 2017-2018: worked on an internal project in infrastructure. Not much to say
|
||||
about it, it is gone now.
|
||||
- 2019-2021: worked on interesting and important infrastructure work: OS, host
|
||||
access, user+groups NSS module and distribution layer. An exploratory
|
||||
personal project with the same theme is [turbonss][turbonss].
|
||||
- 2022-2023: bootstrapping arm64 for compute. [I wrote a bit about this]({{<
|
||||
ref "log/2022/how-uber-uses-zig" >}}). There were many past-2022-April
|
||||
developments, and I am working on an official Uber engineering blog about
|
||||
this. Should come out in a couple of weeks.
|
||||
|
||||
What was so noteworthy?
|
||||
-----------------------
|
||||
|
||||
I met and worked with many amazing people. If I were to single out *one*, that
|
||||
would be Dan Heller, who hired me in Amsterdam, and who I've been working on
|
||||
and off ever since. Among other things (a book!), he wrote [10
|
||||
tenets](https://medium.com/@daniel.heller/ten-principles-for-growth-69015e08c35b),
|
||||
which I regularly use and recommend to others. I am not putting a second name
|
||||
here, because where do I stop?
|
||||
|
||||
I used to do 2-3 yearly 5-12 day US trips. At the beginning almost exclusively
|
||||
San Francisco. After ~5'th trip or so I started to look for things to do during
|
||||
the weekends and (quite by accident!) found likeminded individuals who are
|
||||
willing to join for crazy drives/flights/weekend trips with me. And oh the fun
|
||||
we had together during those short stunts.

||||

|
||||
|
||||
The engineering culture is very strong, I learned many valuable lessons: both
|
||||
from anecdotes and actual experience of:
|
||||
- Built something that nobody needs. I spent my sweat, blood and tears doing
|
||||
it. I had a small child at a time, and, unfortunately, sometimes my
|
||||
priorities were not chosen wisely. I am older now and hopefully wiser.
|
||||
- Built something the organization really needs: an [NSS][nss] module with a
|
||||
distribution layer. I saw the steady uptick in use. The edge cases, scaling
|
||||
problems, lots of customer support (and documentation improvements). Lessons
|
||||
of ossification, client-side metrics, privy of my dependencies.
|
||||
- Tried the corporate promotion lottery. 3 times! The third time was
|
||||
successful. I originally thought it was a lottery (when I "lost" it). Turns
|
||||
out it does not matter how much competence I show, or work I do, on a project
|
||||
that does not matter as much for the rest of the organization. I got my
|
||||
promotion for NSS and host access, things that others actually needed and
|
||||
valued.
|
||||
- We did [Crane][crane], god damn it. A 5-year org-wide project that completely
|
||||
changed how we do infrastructure. Lots of technical and organizational
|
||||
complexities. We had very strong leaders, a clear vision and stamina to keep
|
||||
going. Crane was finished[^1] on the week of this blog post.
|
||||
- Onboarded a new novel technology (zig) and established a relationship between
|
||||
Uber and the Zig Software Foundation. Zig is currently on critical path at
|
||||
Uber, *probably* the second most-invoked compiler after Go. I am proud of
|
||||
that and hope it will serve as a beachhead for the conservatives. If the
|
||||
previous sentence does not make sense, look up ["crossing the chasm
|
||||
beachhead"][ddg]. Thanks to my weekend drive during the previous business
|
||||
trip (probably my last with Uber), I met Andrew Kelley in his home town
|
||||
Portland. We had lunch in the food court and went for an exactly 2-hour hike.
|
||||
Besides learning and onboarding new technology, I feel very much part of the
|
||||
community.

|
||||
The end is near
|
||||
---------------
|
||||
|
||||
There is much, much more to cover than the above, I had a great time. Great
|
||||
people, experiences and organizational awareness. I even did 5 trips as a
|
||||
driver during working hours, and this was encouraged by my manager and the
|
||||
team. I am still having a good time, but, given the expiry date, it is
|
||||
different: the office is shrinking, colleagues either leave the company or
|
||||
relocate to Amsterdam or the US.
|
||||
|
||||
I will take the summer off. I may do some consulting in Autumn. So if you want
|
||||
to talk build systems, systems programming or arm64, [contact me]({{< ref
|
||||
"contact" >}}).
