Doowii | Remote (US) | Full-time | https://doowii.io

Doowii is building an “AI operating layer” for education analytics: connect your institution’s systems (SIS/LMS/CRM), and non-technical teams can ask questions, explore, and take action with integrated workflows and highly customized data ontology.

We’re hiring SWEs to ship AI-first product experiences and infrastructure.

Roles: - Senior Software Engineer (AI Product / Backend) - Software Engineer (Full-stack, AI) - Implementation Engineers (FDE or CXE)

What you’ll build: - LLM-backed app features: multi-step query/reasoning flows, conversational UX, follow-ups, citations, and “show your work” - Evaluation + reliability: offline eval sets, regression testing for prompts/tools, quality metrics, guardrails, and latency work - Agentic workflows: tool-calling, retrieval over structured sources, workflows that can debug/repair queries and guide users to the right next step - App/platform foundations as needed: APIs, auth/RBAC, job orchestration, observability, and cost controls

Stack (approx): Python, TypeScript, modern web app stack, LLM tool-calling/RAG patterns, GCP.

You might be a fit if: - You’ve shipped real product features (backend + app), and care about UX + correctness - You have experience building LLM-enabled systems (or you’ve built strong distributed/backend systems and want to go deep on applied AI)

Comp: competitive salary + meaningful equity (seed-stage)

I don't understand the obsession with ClickHouse. While it seems like it fits this particular use case, it still deals with the same limitations and challenges of columnar DBs. Your queries will be very fast with counts/averages, but there's a tradeoff with other functions: inserts are efficient for bulk inserts only, your deletes and updates are slow, no secondary indexes...

While Clickhouse can be lightning fast, is it really designed to be a main backend database?

Congrats team!

Can someone explain how this is more powerful than someone use an Python/R based workflow? E.g., I currently use a combination .ipynb, python scripts, and RStudio and this feels like it covers everything I need for any data science project.

I had this exact same thought when I read the headline. It seems like MS and others are viewing ML as a similar opportunity to Big Data/BI ten years ago. You saw the "democratization of data" as people with little technical skills could suddenly create analytics dashboards within tools like Tableau.

In my opinion, it's far too easy to make a critical mistake during design/implementation of ML to follow this same path. And what's more, if you mess up making an analytics dashboard, it's usually fairly obvious. In ML, there are MANY ways to mess up a model and you have no easy way to tell.

If someone doesn't have the technical experience behind creating these models, I would not trust any output they give me from using one of these tools. And if they do have the experience, they would certainly not be choosing to use one of these tools either.

A lot of that speculative growth comes from Turkey's comparatively younger population (hence more productive hours worked each day), and their continued population growth. Germany's demographics are sliding the other way, with an aging and stagnating population.

Are you sure? 25,000 employees * 12 months * 1000 = 300 million in economic activity.

Obviously not all 25000 employees would get an extra 1k, but the point being...these things can scale significantly when you're talking about Amazon. It's not a trivial thing for SMBs to fill the void that Amazon is leaving.

The issue I'm having with this comparison is that you are equating the "nights stayed" with the points earned (the more accurate currency).

>They each have a rewards program which grants one free night for every night stayed.

It's a lot more fair to say for every $1000 spent, you have enough points to redeem a free night. In which case, some people might choose to spend more nights at the cheaper Fairfield Inn, and some might choose to stay fewer nights at the luxury Ritz. The bad money is not driving out the good.

It's true when it comes to qualifying nights, people will try to hit elite night requirements at cheaper properties. But that's not driving out the business for higher-end properties. Especially because award redemption is (mostly) based on how much you spend, not how many nights you stay.

This sounds like a misinterpretation of Gresham's Law. That's specifically talking about currency, which I suppose in this case would be the reward points. There is no "good" vs "bad" version of the currency though. Certain types of points are not driving other types of points out of circulation. The value of the points depends on how you use them, with people more eager to spend points on high-value redemptions.

Mux wrote a blog post about this too: https://mux.com/blog/how-we-used-machine-learning-to-predict...

Using machine learning to parse text helps, but it's still not a perfect solution.

ride sharing isn't exactly very profitable at the moment. I don't think the revenue would offset the additional engineering/product costs of just running the rideshare service, much less the cost of testing.

Author here: please feel free to ask any questions/comments on our methodology. I designed the neural net, which is basically video classification mapped to bitrate-ladders. Interested in any feedback!

For anyone interested in additional research and debate on this topic, I'd recommend watching Pinker and Spelke's excellent debate on Youtube. As some might remember, in 2005 Larry Summers was fired from Harvard for making similar comments regarding right tail cognitive abilities. Pinker/Spelke lay out great points on both sides of the issue.

Sex Differences in Cognitive Abilities by Diane Halpern is another important work in this subject. It was published back in 1986, so the research on topic has been going on for decades. During that time, virtually every piece of research supports the claim that innate differences in mental abilities exist between the sexes. The extent of those differences is hard to measure, but this new paper is nothing new. It's just adding more support to an already large body of evidence.
