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 [email protected] with subject: “{Your dog’s name} wants {something they want}.” In the body, tell us what interspecies communication means to you.

We're a quantum computing non-profit organization, and we are looking for a web developer.

The job is classical — mostly building web portals — but those portals open into the quantum world.

Quantum computing knowledge is a plus, but not required. The initial project is a platform to understand the trajectory of quantum computing. The focus is on data visualization, so strong skills in that area are preferred. The candidate will work mostly alongside quantum engineers and researchers, so ownership to work independently on the classical side of things is important.

The stack of the main web project is PERN, but the organization maintains other projects in Python.

What we're building:

* A general-purpose automation platform for healthcare ops, powered by LLMs

* A system that reads unstructured documents, fills out payer forms, and explains rejections

* Tools to automate patient discharge planning in hospitals

* A foundation for making AI in healthcare safe, observable, and human-in-the-loop

What we're looking for:

* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship

* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability

* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed

More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.

Phosphor enables the development of the built world (e.g. from real estate to energy projects) to be managed agentically by building programming languages and observability primitives (like version control) on top of a hypergraph.

Our primary technical bet is that if you capture annotated "diffs" of user information with the appropriate annotation, you can create path-dependence to train AI models in an AlphaGo like context. By doing so, we achieve agentic experiences for markets that have never even had an opportunity to imagine what life would be like with basic observability.

Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Hi there, I’m one of the co-founders of a remote AI startup that’s reimagining video editing with cutting-edge LLM technology. We’re small, friendly, and flat in structure, and we place a high value on autonomy, initiative, and embracing complex challenges (instead of waiting for step-by-step instructions).

Our stack: React (front-end), Node.js (API backend), Docker & Kubernetes for deployments, AI/LLM APIs (OpenAI, Claude, Llama, etc.)

We’re looking for: Proven experience as a Product Owner/Manager in an Agile startup environment· Strong technical background with ability to understand and write API specifications · Expertise with product analytics tools (e.g., MixPanel) · Proficiency in prototyping tools (e.g., Axure RP, Figma) · Demonstrated experience using modern AI tools (LLMs) to enhance productivity

Nice to have: - Video/video-editing product background · Master's degree or higher in Software Engineering or related field · Professional certification(s) in product management · Startup experience

3. we are live on Zoom with customers twice a month to launch new features, talk through the roadmap, take feature requests, etc. If the Product Owner (who is expected to take on this role over time) is against the idea of being visible on video themselves, they might just not be a match for this product and company.

We’re creating robots that autonomously construct buildings. We design all of our hardware and software in-house in central Amsterdam, starting with autonomous bricklaying robots.

Building a robot like this means solving all sorts of interesting challenges: figuring out the robot's position with sub-mm precision; navigating autonomously around the building site; automating measurement and calibration of new robots; lots of distributed systems and so on.

Our robots are now continuously deployed on customer sites and we are earning real money as a masonry contractor. The full team is more than 50 people and we're growing rapidly to meet demand.

Our stack is mostly: Rust, TypeScript, Python, NixOS.

Some open roles:

- Software Engineer, Controls

- Software Engineer, Machine Vision

- Assembly/manufacturing technicians and robot operators

P.S. We're always on the lookout for very strong generalist engineers who can operate at any layer of the stack (firmware, networking, UI, application code - whatever's needed!) Drop me an email if this sounds like you.

We provide isolated runtimes for executing untrusted code, mostly generated by LLMs. Our sandboxing is powered by a combination of WebAssembly, V8, and microVMs. Our customers do things like extract data from log lines at run time by asking claude-3-7-sonnet to generate a parsing function on-the-fly and then sending it to us for execution.

Things we need help with:

- Our API (https://docs.riza.io/) (Postgres / Go)

- Our account dashboard (Postgres / Go / React / TypeScript)

- Our code execution engine (Go / Rust)

- New products including code generation workflows (Anthropic / OpenAI experience a plus)

We’ve raised seed money, but the whole company is currently just me, Andrew and David working out of a converted warehouse on Alabama St. We’re second-time founders, so we know the risk we’re asking you to take and we’re prepared to compensate accordingly.

You'd be working with engineers who previously worked at Google, Amazon, Helsing, Darktrace and an F1 team. We build drones (software and hardware)

We're looking for engineers that straddle real world problems, and use technology as a solution. We prefer personal projects or relevant hobbies, not hard leetcode questions. We value collaboration: pair programming, discussing, teaching and learning from others. We're looking for mission-driven engineers. People who see problems in the world and want to help solve them.

You'd be working with me to build the most intuitive, performant, and modern mission planning and flight monitoring software for drones, and related applications (tools for drone design and manufacturing). For my project, we use React, Tailwind, Node, drizzle-orm, Postgres, SQLite, deck.gl, Python, FastAPI, asyncio, and more. You're allowed (and compensated) to use AI services.

Because we are a small team, you will be noticed and rewarded for performance.

*Please don’t apply if any of these resonate:*

• You prefer narrow ownership—“I only touch the backend or the code I've written”.

• You think it's more about "who you know, not what you know".

• You haven’t actively learned a new tool or hobby in the last year.

If interested, email my temporary email: [email protected] with your CV and some personalised information about why you'd be the right fit.
