Lessons learned from the Executives at PyData session at PyDataLondon 2022
Lessons from the Executives at PyData session at PyDataLondon 2022
We ran our first post-pandemic in-person PyDataLondon conference a week back in central London, bringing circa 400 data scientists and engineers together for a packed and really solid schedule. We had 3 days of events, a social with a very generous bar, spontaneous break-out sessions and lots of lively conversation. It was lovely to see folk again for the first time in 3 years. Personally I've been cautious having become a father during lockdown, so this was my first "big" event since lockdown...it was a bit overwhelming and I attended in chunks, avoided the crowded sections and tried to keep my mask on. I'm really glad I attended, thanks to all those who came, presented and volunteered.
I ran a session for "Executives at PyData" aimed at anyone with a leadership role. We discussed a whole pile of issues, I've written up some notes below. If you're a leader, you'll want to take a look. I'm also scheduling two follow-up Zoom calls (details below) to continue these discussions, one on Team Structure and one on Backlogs & Derisking. Reply if you'd like to attend to get the calendar invite for the Zoom call.
Further below you'll find 8 listings for jobs at the likes of DeepMind, Deliveroo up to Staff Data Science roles.
Thanks again to my designer friend Myles for the great volunteered t-shirt design for the conference this year. If you need graphic design work, talk to Myles.

For those of you who have been waiting a while for me to get these listed - apologies, being the father to an infant has eaten a lot of time this year and I've had to take things sensibly before scheduling new courses.
Notes from "Executives at PyData" (PyDataLondon 2022 conference)
I ran this session on Saturday morning at the conference. This is the 6th time I've run this (both in London and on the Global virtual conference), we vote on topics of interest to those in the room and work through them under "Chatham House Rules" (i.e. any private details stay in the room). We had a lively discussion about Team Structure, Building a good Backlog and Derisking.
I'm going to continue these conversation in future Zoom calls - details below if you'd like an invite.
This session, like my talk, and the talks by all the other speakers are given during volunteered time on behalf of the PyData community. If you've benefited from these talks, do please remember to thank your volunteer speakers.
We had 50 leaders in the room which represents circa 12% of the attending conference members. This grows every year as more and more people take on leadership roles in growing Python teams.
We talked about "what makes for a good team structure and what challenges your teams?". A great post-pandemic discussion also broke out on "how do we move from my hybrid to fully-remote?".
Several people noted success with the Spotify model, notably that the Guild model works well if it is built by passionate people and not designed by management. It was noted that the best tech leads are not the "ones needing a promotion" but those who are great at sharing knowledge. Some people ask "will this person embarrass me?" as a way to figure out if a promotion in a team is a good idea (it feels basic but it probably isn't silly).
Several orgs have moved during Covid from an on-site or hybrid to fully-remote model with success - the key is to promote writing everything down and communicating in written form. Those who have to fight an "onsite/meeting-focused" mind-set find this difficult. 40+ of the 50 ppl in the room are in a hybrid environment, only a couple are on-site now. Less than 10 were 100% remote.
Tools mentioned for remote success include GitLab, Confluence, tuple - Mac only for realtime sharing, moving from GDocs to Notion, slack, email and making sure daily verbal touchpoints are in place (to talk to all the leads). "Roulette coffee chat" was mentioned by one to get to know someone you don't know (nice idea). What tools have worked for you?
John Sandall also added this article on tools.
One counterpoint for the hybrid environment was that anyone going on-site is more likely to meet senior leaders so they get a career advantage. There's no easy way to avoid this and teams were preferring to move to 100% remote if possible. Have you solved this issue?
After the main discussion we had 13 staying for a further chat on Team Structure during lunch, in part focused on those moving from a hybrid to fully remote setup (we'll explore this in one of the future calls - see below).
Building a good project backlog
A good backlog is essential and can't be built "when you've run out of stuff to do". To my mind it is an essential activity for the whole team to partake in, spreading into the wider organisation and learning who has pains and desire to solve them.
One key is building relationships - that takes time and effort. You can then find pains and explain if their problem is worth a DS solution. Embedding people in product teams means you can learn the roadmap for those teams. Good collaboration partners are probably willing to commit resources early (so it is less about what they want, and more about what they're willing to commit). Go look for problems in that organisation and be willing to piggy-back some DS projects on the back of these (as these projects are probably important to the org). Always wrap everything up in a discussion on business value.
Some people time-box strongly to avoid project creep - but that only works if you've had prior success to win trust. Getting granular commitment to projects, building up from easier stages, showing value incrementally, is a very sensible way to advance a bigger idea. If you commit to too-large-a-thing and it fails, you erode trust which is hard to win back.
Think more about "this isn't a DS project, it is a 'reduce overbilling project that might happen to use some DS'". Deliver something of value which works end-to-end (even if it is just uses a random number generator) in the first iteration to show progress. Derisk the apparent cost of a project by getting an supported intern to take the first steps. Fail fast with quick PoCs to show that risk is reducing.
One of the ways I know I bring value to a project is to help the team type less and talk more to figure out if we're actually solving a valuable problem. Often you can lose sight of the big picture when challenged by a detail and knowing when to step back and maybe pivot can be crucial to maintain momentum.

Continuing the conversation on Success via Zoom
I'm going to run two virtual events focused on getting to more success. Please reply if you'd like a calendar invite to either of these:
- Monday July 11, 4pm, Team Structure - getting a good structure for your org, hybrid vs fully remote practices, processes that support your team, how to avoid being left out
- Monday August 8th, 4pm, Backlog & Derisking & Estimation - how to build a backlog, derisking quickly and estimating the value behind your projects
My Success course deals with some of the above topics, I'm hoping that we can explore existing pains and solutions in these public calls and maybe some of you would like to join the subsequent course for a deeper dive into valuable tools and processes.
