Ask HN: Who is hiring? (April 2025)

[dead]

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

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.

Sneos.com | Founder | REMOTE | I help compare outputs from multiple AI chatbots

At https://Sneos.com, I've built a platform that allows users to write once and compare outputs from multiple AI models like ChatGPT, Claude, and Gemini side-by-side. This helps users understand the unique strengths and perspectives of different AI systems without the hassle of copying/pasting between services. Current Needs:

Growth Hacker (part-time/contract): Looking for a creative, data-driven growth specialist to help me scale the user base and optimize conversion from free to premium tiers. You should have experience growing B2C SaaS products and be comfortable implementing and analyzing marketing experiments quickly.
