PlantingSpace | Full-time | Remote (EU time zone) with quarterly meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach goes beyond state-of-the-art LLMs by combining algorithms in symbolic ways, to provide novel capabilities like performing multi-step analysis, displaying a verifiable reasoning path, and assessing uncertainty. We envision applications supporting and automating analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.

Want to contribute to cutting-edge work in AI? We’re looking for:

* Senior Program Synthesis Engineers

* Senior NLP Engineers

* Finance & Operations Manager

Polaron | Senior ML Engineer, Senior Software Engineer | London, UK | ONSITE | https://polaron.ai/careers.

Polaron is an Imperial College London spinout using generative AI to bridge the gap between process (how materials are made) and performance (how materials behave). We’re building a platform that enables materials designers to use these state-of-the-art AI techniques in their day-to-day work. We’re a small, well-funded team, and have just won the UK Government’s inaugural Manchester Prize [2] for AI innovation and public good.

As a Software Engineer at Polaron, projects on our roadmap you could work on include: - Scaling our canvas-based frontend to handle images with greater than 10k x 10k pixel resolution. - Intelligently autoscaling our GPU cluster in response to customer demand. - Building a public-facing API, in addition to our web-based interface.

As a Machine Learning Engineer at Polaron, projects on our roadmap you could work on include: - Optimising efficiency and robustness of our existing algorithms for material characterisation, exploration and optimisation; - Adapting cutting edge machine learning methods for material science applications.

Tech Stack: TypeScript (React / Next.js / Express / Prisma), Python (PyTorch), PostgreSQL, Docker, Kubernetes, AWS, Terraform.

Sarama | Hardware Aesthete | On-site (San Francisco, CA) | Full Time | Must have a dog | https://www.sarama.ai

Company: We’re building smart collars and other devices to translate dogs into our language—using audio and motion data. We want to know what our dogs want and are on a mission to rethink the entire healthcare & training industries as we better understand them. We are mostly software people and have built our own models for dogs (soon expanding to my new cats).

Role: Hardware, firmware, and software. Moving fast will be a mix of LLM, research, hacks, and rapidly typing. Build fast, no hand-holding. First product’s a warm-up. After that, it gets real.

You: Full-stack in the real sense (hardware + firmware + software) Fast, independent, opinionated Move fast, care deeply Must have a dog Culture: Obsessed with dogs. We’re building the interface for interspecies communication. Not just “pet people”— we believe dogs are family members fully including legally (we can discuss the changes in law on our call).

Apply: Send us an email with your portfolio (or something similar) with a picture of you and your dog to Email is hidden with subject “{Your dog’s name} likes {something they like}” and in the body include what this tech means to you.

Elsewhere | San Francisco or Remote (US Time Zones) | Contract or FT | https://elsewhere.zone

Are you a web developer who’s always wanted to make indie video games? This is for you. Elsewhere is a San Francisco-based game studio building multiplayer roguelike games. We’re working on two projects, one of which is a roguelike deck builder in the vein of great titles like Inscryption and Slay the Spire with a little Pokemon TCP and Marvel SNAP thrown in. We’re building games with TypeScript, React, and HTML/CSS as well as Websockets (via Colyseus). We’re using generative AI in a fascinatingly new and creative way that naturally extends game mechanics into something tens of millions of people will absolutely love.

Ideally, you:

* Have worked as a software engineer before, ideally on a small team.

* Have built and shipped games before, either professionally or on your own time.

* Love games yourself, and have always wanted to work in the games industry.

* Know the web stack (TypeScript, React, etc) like the back of your hand

We’re stealth but backed by some of the top investors in Silicon Valley, including Floodgate and a16z SPEEDRUN. My previous startup was Human Interest (YC S15), a fintech co that today is valued at $1.3B. My intention is to outdo it many times over with Elsewhere. We’re building the the Blizzard, Valve, or Nintendo for the AI age. I hope you’ll consider joining us.
