Member of Technical Staff – Pre-Training (£150k-£225k + Equity) at Adexis

**This is a job that Jill, our AI Recruiter, is recruiting for on behalf of one of our customers.** She will pick the best candidates from Jack's network. The next step is to speak to Jack. **Job Title** Member of Technical Staff -- Pre-Training **Salary** £150k-£225k Equity **Company Description** Adexis is a London-based frontier research lab building the "somatosensory cortex" for Physical AI, backed by leading VCs and researchers from Anthropic, ElevenLabs, and Google DeepMind. They are creating a talent-dense organization focused on bringing the power of touch to machines to achieve physical general intelligence. **Job Description** As a founding hire, you will architect and train Adexis's core visuo-tactile foundation model. You will own the entire pipeline, from the tokenization of visual and tactile signals to large-scale pre-training and downstream adaptation. This role defines how robots understand the physical world through touch, setting the scientific direction for physical general intelligence. **Location** London, UK **Why this role is remarkable** * Join a founding team of outliers inspired by the Manhattan Project and Bell Labs to solve dexterous manipulation---the unsolved "missing piece" of Physical AI. * Work alongside researchers from Anthropic and Google DeepMind with the backing of top-tier VCs to train massive, novel multimodal models from scratch. * Enjoy massive scientific ownership and autonomy, defining a new field of visuo-tactile intelligence with a significant equity stake in a high-growth lab. **What You Will Do** * Design and own the end-to-end model architecture, determining how visual and tactile signals are tokenized and fused into a single learned representation. * Develop a staged training pipeline involving large-scale pre-training on passive data, proprietary contact-rich data, and specialized downstream robotic adaptation. * Establish the evaluation framework for tactile understanding and set the scaling roadmap as compute and data resources expand significantly over time. **The ideal candidate** * Proven experience training large-scale multimodal or sequence models from scratch, with deep knowledge of data curricula, ablations, and debugging silent failures. * Strong technical instincts for multimodal fusion and a track record of shipping models where non-visual modalities measurably improve system performance. * High-ownership mindset with the ability to define architectures and make decisive technical choices when existing literature offers no clear direction. **Who are Jack \& Jill?** Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support. And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate. **How does this work?** * Jack's an AI agent for job searching and career coaching. He works for you. * Jill is the AI recruiter working for the company. She recruits from Jack's network. * If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives. **We never post fake jobs** This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description. We appreciate this can make them look a bit suspect, but there isn't much we can do about it. Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
