JuliusSu··on Ask HN: Who is hiring? (October 2026)
SKIES (Visual Choices AAC) | iOS Developer, embedded at the UCLA Kasari Lab | Los Angeles | ONSITE | Full-time, 6 months | $65k ($130k annualized)

3% of children are autistic. 30% of them at age 9 remain minimally verbal: a handful of single words, never put together into a sentence. If that evokes something in you beyond the number, read on.

The Kasari Lab at UCLA, one of the top autism research groups in the world, has developed a play-based intervention that helps minimally verbal autistic children. Over 24 weeks, many make real gains in communication and social connection. But it combines assistive tech setup with play improvisation, which makes it challenging to deliver, and it is not standard practice.

You would build Visual Play, an app that takes pieces of this intervention (and others) and makes them easier for regular clinicians to do while playing with a child. You'd be embedded in the lab from day one, paired with an implementation lead who spends their weeks with clinicians. You'd own the app end to end.

Visual Play is funded by an NIH SBIR award to SKIES, a small Pasadena company started by Caltech alums. We make Visual Choices, one of the most-used communication apps for early communicators. This is a six-month Phase I; if the prototype works, Phase II follows, and so does the product.

An ideal candidate:

- is comfortable being close to, and taking feedback from, researchers and clinicians

- has shipped real native iOS apps

- uses AI as a force multiplier, but understands the code it produces and is not dependent on it

- builds large and complex, yet maintainable, systems

- is resourceful, motivated, and tenacious

- is a calm, respectful presence in a research lab

In person at UCLA, five days a week. Starting January 2027. The interview includes a 60-minute collaborative coding session, no AI assistants.

JuliusSu··on Individualized Spaced Repetition in Hierarchical Knowledge Structures
Hi Jason, we had discussions at Caltech on some of these ideas many years back. We do have a patent, now lapsed, on doing spaced repetition on knowledge graphs: https://patentimages.storage.googleapis.com/ff/ae/6d/3483859...

Math pedagogy in the US leans to understanding being more important than practice. This is wrong. As you point out, understanding more often comes from practice. To correct this imbalance, software like your company is developing is useful, as are platforms like ALEKS, iReady, etc.

The challenge is addressing the social aspect of learning -- the benefits students get from working and learning together. Is it still a classroom if all the students are doing different things?

Of course, students come in with different abilities and levels of preparation. Differentiation that works in a class setting is very hard. Software is the easier part. Students who are motivated to learn and can grow with guidance from a computerized tutoring environment -- helping them is also the easier part.

JuliusSu··on Is the Immediate Playback of Events Changing Children’s Memories?
This is similar to the point made in Ted Chiang's short story "The Truth of Fact, the Truth of Feeling." When writing replaced oral storytelling, people's memories and experiences shifted as well. He makes the case that having one's experiences always available for playback will create another kind of shift.
