chs20··on Ask HN: Who wants to be hired? (April 2026)
Yes, surely. Just using this as another channel, often the most interesting opportunities are rather hidden.
chs20··on Ask HN: Who wants to be hired? (April 2026)
Location: Tübingen, Germany

Remote: Yes

Willing to relocate: Yes (Europe/UK; open to exceptional opportunities elsewhere)

Technologies: Python, PyTorch, NumPy, transformers, multimodal ML, LLMs/VLMs, adversarial robustness, AI security, red-teaming, research

Résumé/CV: https://chs20.github.io

Email: schlarmann.christian@gmail.com

PhD researcher in ML at the University of Tübingen seeking Research Scientist / Research Engineer roles. I work on robust and secure machine learning, with a focus on multimodal models, adversarial attacks and defenses, and AI safety. Publications include ICML and NeurIPS; I also have hands-on experience red-teaming frontier AI systems. Open to AI security, multimodal/generative ML, and strong research-oriented ML roles more broadly.

chs20··on Show HN: I built a game to help you learn neural network architectures
Transformer / attention block is missing
chs20··on Scientific journal publishers and editors say they are being offered bribes
In my experience, papers published in these "special issues" don't really get any attention.
chs20··on Can Microsoft Flight Simulator help me learn to fly or make me a better pilot?
Simulating cross-wind landings doesn't sound that hard, why do you think current sims don't do it well?
chs20··on OpenAI staff threaten to quit unless board resigns
Seems like Microsoft is getting the rest of OpenAI for free now.
chs20··on In search of the least viewed article on Wikipedia (2022)
Why does he need to subsample? Seems like it should be feasible to find the minimum of a 6M array
chs20··on We are beginning to roll out new voice and image capabilities in ChatGPT
Will be interesting to see if they have taken any precaution in terms of adversarial robustness in particular to vision input.
chs20··on Consensus: Use AI to find insights in research papers
From which database are the papers that it searches?
chs20··on λ Calculus (2013) [pdf]
What is the motivation for lambda calculus?
chs20··on Travel across Germany with the 49 Euro ticket
But only regional trains. To me the biggest advantage is not having to worry about what tickets to buy in foreign cities.
chs20··on Lost all my content writing contracts. Feeling hopeless as an author
I'm pretty sure you can't reliably distinguish LLM text from real person text.
chs20··on Seven years on, what do we know about the disappearance of flight MH370? (2021)
I agree that much evidence points towards the pilot intentionally crashing. However, it's not proven and constructing a story around this theory is a bit distasteful.

Otherwise, the article is quite interesting.

chs20··on Syzygy Chess Endgame Tablebases
16.7 TiB for the seven piece tablebase.
chs20··on Why are there so few dead bugs on windshields these days?
Honestly, I had tons of bugs on my windshield this summer.
chs20··on Show HN: Shoot the neural network before it shoots you
What is the input and output data of the neural network?
