Toolhouse | Software Engineer (Fullstack) | Onsite (Austin, TX) | Full-time | $180k + Equity

What if you built a product that helped thousands of engineers build AI features and AI agents? That is what we do at Toolhouse.

We are a high performance team working in the "infra/backend" horizontal space. We are building the infrastructure that powers AI products and agentic workflows.

We're building a team of special people that want to win in Austin.

This is no 9-5 gig. You're in or you're out. This is a startup and we need to ship code to make this thing happen. You will learn to trust your gut feeling and the data attached to any decision, and we do it all together.

We are looking for engineers who are excited to do great work. - Engineers who trust their instincts and who also love to discuss ideas and write them down. Humans invented writing, and built the future. - People who enjoy building developer tools that can really help other developers.

No BS attitude. Just engineers shipping code and having a good time doing it.

The role: You’ll work across our stack (TypeScript, Python, Postgres, Docker), building powerful backend and frontend for a population relying on function calling infrastructure, RAG, evals, and tons of data (prompts).

Perks: Equity vesting from day one, unlimited PTO, lunches, a real family outside of your own.

We’re in-person & in Austin. We do not sponsor visas.

We don't want your resume, show us what you shipped on Github - send it via email to our toolhouse.ai inbox: hello@...

AMD | Onsite or Remote | SF Bay Area (preferable) or other locations in USA/Europe/Canada | Full-time

We are building a fundamentally new programming language for authoring high performance machine learning kernels on AMD GPUs and the rest of our hardware portfolio. To enable this, we are looking for a wide variety of roles ranging from GPU performance experts, MLIR/LLVM compiler wizards, programming language specialists and machine learning for systems researchers.

We are looking for candidates with deep domain expertise in any of the areas listed above (atleast 5 YoE and contributions to major OSS projects or publications in relevant conferences)

If this sounds interesting, please reach out to me via email (harsh dot menon at amd dot com) with the title "Interested in Wave Language" and your resume along with a brief description of what role you are interested in and why we should consider you for the role.

Sarama | Canine Language Specialist | On-site (San Francisco, CA) | Full Time | Must have a dog | praful@sarama.ai

Company: We’re building smart collars and devices to decode dog communication—using audio, motion, and behavior data. Our goal is to understand what our dogs are trying to say and rethink the worlds of training, healthcare, and companionship as we uncover their language. We've trained models for dog vocalizations and movement patterns, and now we’re integrating behavior and intent.

Role: You’ll work closely with our engineering team to help ground our models in real-world behavior. From structured training sessions to experimental communication techniques (e.g. dog buttons, symbolic vocalization training), your work will directly shape how our devices interpret canine communication. You'll guide the design of training protocols, data collection, and help teach dogs how to speak using structured methods.

You:

+ Experience in dog cognition, vocalization, and training techniques.

+ Familiar with AAC devices or button-based communication systems.

+ Scientific mindset with hands-on experience.

+ Passionate about language and cross-species understanding.

+ Must have a dog (ideally one you’ve trained using vocal cues or buttons)

Apply: Send us an email with a video or write-up of your past work (bonus if it includes your dog using buttons or vocal cues) to hello@sarama.ai with subject: “{Your dog’s name} wants {something they want}.” In the body, tell us what interspecies communication means to you.

---

If you refer someone to us, tell them to let us know and we'll send you a gift! (we aren't able to give a cash bonus just yet soon though)
