Ask HN: Who is hiring? (December 2025)

9 Mothers Defense | Robotics Engineer, Data Scientist | Austin TX | Full-time | ONSITE

We're building AI-driven turrets that stop hostile drones - where robotics needs F1-level speed.

We're looking for smart, T-shaped teammates: people who are experts in one area but happy to jump in wherever needed. Our software team is small, so every member makes a real impact.

If you want to write motor control in Rust, optimize camera processing with custom CUDA kernels on Jetson, or rework a transformer-based tracker to handle small objects - you can do that here, and much more.

US persons only

Tendavo | Founding Engineer | Stockholm | On-site (Hybrid) | Full-time | Visa | https://tendavo.se/

The Team: CEO: ex-McKinsey | CTO: +13 years of startup experience, previously founded a data startup scraping 50m pages/week.

The Role: You will work side-by-side with the CTO to build the platform from the ground up. You get full technical ownership to design agents and LLM workflows that replace our manual routines. This is a high-agency role: We have validated Product-Market Fit; your job is to scale it.

Tech: Python (AI & core systems), PostgreSQL, TypeScript, GCP

We offer equity, mentorship from a technical team, and a clear path to VP/Head of Engineering.

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome. We also just acquired a fine-grained authorization company ( https://fusionauth.io/blog/fusionauth-acquires-permify ) and are going to be building in that area as well.

There are a lot of companies in the auth space, but we feel like we have something special:

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our app to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; there are plenty more features to add)

* the CTO is the founder and still writes code

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already

Our core software is commercial with a "free as in beer" version. We also open source much of our supporting infrastructure. Technologies and standards that you will work with: Modern Java, MySQL, PostgreSQL, Docker, Kubernetes, OAuth, SAML, OIDC.

BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, Posthog, and Brex automate the operations work that lets them provide their customers with world-class product experiences.

We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.

Joining us will mean solving hard problems at the frontier of AI adoption, including:

- maintaining performance at scale

- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.

- building agent and workflow systems that automate real work for customers

- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly

- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems

Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python

Benefits:

- unlimited PTO

- $100/mo education stipend

- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work

- health insurance
