I'm Roman, co-founder of 9 Mothers. We're building AI weapon systems in Austin, TX. Our first product is designed to stop group 1 suicide drones. We started in 2025 and are still a small team of fewer than 20 people.

We're hiring for a lot of roles, but mostly in software and robotics. I'm primarily focused on robotics, so if you have a strong background in robotics, reach out to me directly at (name)@9mothers.com.

My name is AJ Forsythe and I'm the Founder / Chief Chicken Tender at Coop! We're an Austin TX based company on a mission to build the world’s largest decentralized food production network, starting with AI powered chicken Coops. We’ve been in the market for about 18 months and our customers are in 48 states and will generate about >10M eggs this year. It's insanely fun to work on and we have a shot at building a huge business in the connected urban farming space. If you’re big into computer vision, consumer products that are fun, and an awesome team we would love to chat. The Coop has an automatic door + cameras doing computer vision work (predator detection, egg alerts, remote health monitoring, etc). It's a super exciting time and are seeing directional product market fit which I'm thrilled about. Seriously go check out our website, it's a super fun + amazing product.

We’re a tight-knit team of 5 people with 15+ years of experience working together. We’ve been through YC, started and scaled multinational million-dollar businesses together, taking them from idea to acquisition by a Fortune 50 company. We’re gritty and passionate without taking ourselves too seriously - and we’re here to build something really exciting that helps people reconnect with their food and the planet. We're VC backed (call it $5M) by some of the world's best investors but we are a scrappy small team that moves fast. We have an absolutely fantastic CTO Ryan that I'm looking for his / our right hand person to work alongside with. I think the term full stack is overused but that's closest to what we're looking for. Also this really isn’t a traditional Eng role, I look at it as we’re a small growing team and you would be one of us working on a ton a cool projects on day 1. Also, we LOVE working with founders so if you've started a company before that's epic.

Oh also, I have a fun project where I want to make a water gun turret that uses our cameras to detect predators and allows you to aim and blast them. If you're into hacking robotics and gimbals etc, please reach out.

You can also reach out to me directly at: aj[at]coop.farm - Just email me your LinkedIn / GitHub / portfolio + why you think you'll be an awesome fit and I'll respond. Please don’t use GPT too much. This is my 3rd company (2 have exited) and I want to build the super solid core team and you might be the perfect fit for us and vice versa. Bwok Bwok! AJ

I'm Robert, cofounder of Riot IQ. We're building RIOT IQ, a professional online IQ testing and cognitive assessment platform for psychologists, researchers, clinicians, employers, institutions, and curious individuals.

We're US based and 100% remote. We are hiring software engineers, full stack engineers, product designers, design engineers, and AI native fresh grads.

The most interesting project is building an AI based human intelligence predictor using our in house assessment data. That means working with response patterns, timing data, item performance, scoring, validation, dashboards, model evaluation, privacy, and product UX.

You might work on a variety of things as well but all related to predicting human intelligence.

What matters most to us:

1. Strong product sense 2. Clear communication 3. High ownership 4. Taste in software, design, and user experience 5. Fast learning 6. Interest in AI, cognitive science, psychometrics, or research tools

Useful experience includes TypeScript, React, Next.js, Node, Postgres, Python, data pipelines, ML workflows, dashboards, edtech, healthcare, or research tools.

Compensation is $90k to $180k depending on role and experience, with equity for the right long term hires. Visa sponsorship is not available right now.

To apply, email robertneir@riotiq.com with your resume or LinkedIn, GitHub or portfolio, and a short note on what you would want to build at Riot IQ.

We are actively hiring and will reply to applicants.

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.
