Art Tech Startup (stealth) | Technical Co-Founder | Remote or NYC | Equity

I'm building an art tech startup, and I am seeking a highly driven full-stack technical co-founder ideally located in NYC. You should ideally have a proven track record of launching and operating tech products that successfully generated sales or a substantial user base in the US or Western Europe.

I am a finance, strategy and tech professional with experience co-founding a dating website that secured paying users in its first month of launch. I handled all non-technical work, including go-to-market, partnerships, strategy, UI/UX design, and marketing. Professionally, I've advised tech executives and founders at early-stage to global enterprises. I know how to build and scale tech products from 0 to 1.

Hey HN! I'm hiring aggressively to scale our team at Airspace Intelligence (https://www.airspace-intelligence.com)

Series B, onsite in Boston (all levels) and Seattle (Senior+).

We're building the software layer for airspace and critical infrastructure operations. Think real-time optimization across thousands of flights, grid assets, and logistics networks — the kind of problem where your state space is enormous, constraints shift constantly, and the humans in the loop are making life-safety decisions on tooling that hasn't meaningfully improved in decades.

We're hiring across Product, Infrastructure, and ML. If you're a performance minded front-end (web) engineer - I particularly would love to hear from you.

Here's one of our roles https://www.airspace-intelligence.com/careers/role?=6462d3d1... - there's a puzzle at the bottom that'll be trivial for this crowd, but it'll get you my email directly. If you go that route, drop "HackerNews" in the subject so I can prioritize you.

If building software for critical systems sounds interesting, I'd love to hear from you.

Hey all, Cassidy (https://cassidyai.com, Series A, ONSITE: New York City) is growing fast and we're hiring across a few critical roles in NYC.

Senior & Mid-level Software Engineers - end-to-end product engineering and helping build systems that scale

Technical Chief of Staff - CTO's operational right hand. Picks up hard, ambiguous problems across engineering, compliance, and commercial conversations and owns them end to end.

Cassidy is an AI agent and automation platform for non-technical knowledge workers. By connecting to a company's knowledge where it lives and building intuitive core primitives, Cassidy lets non-technical teams automate large swaths of busy work, freeing them up to do the work that really matters. Series A, 25 people, growing fast.

Antioch | Simulation Engineer | New York City | Full Time | https://antioch.com

Antioch is building the simulation platform for robotics and perception systems. Spin up full-stack digital twins, run scenarios to test and validate behavior, and deploy, entirely in software.

Role:

Build high-fidelity models of sensors and physical components:

— Design and implement simulation capabilities for sensors, actuators, and interactivity (contacts, dynamics, timing, noise, artifacts, etc.).

— Build and calibrate simulations for one or more sensing modalities (e.g. cameras, lidar, radar, infrared/thermal, UV), including realistic failure modes and edge cases.

- Model the full sensor pipeline where relevant: optics/RF + noise sources + signal processing (e.g. camera ISP behaviors, radar DSP stages).

Partner directly with customers to ingest their existing physical systems into Antioch (robots, sensors, actuators, environments):

— Translate incomplete specs + messy real-world data into working simulation models with clear assumptions and documented gaps.

— Drive the integration to completion: “runs in sim, matches reality within defined tolerances, and is usable by the customer.”

— Design and implement simulation capabilities for sensors, actuators, and interactivity (contacts, dynamics, timing, noise, artifacts, etc.).

— Build and calibrate simulations for one or more sensing modalities (e.g. cameras, lidar, radar, infrared/thermal, UV), including realistic failure modes and edge cases.

How to apply:

Submit an application to https://antioch.com/careers/38387

OR

Email Jackson at jackson@antioch.com with your resume and answers to the following:

- Please explain what robotics simulation experience you have had (i.e. Isaac Sim, MuJoCo, Pybullet, Gazebo, etc.)

- Please explain what sensor simulation experience you have had (Radar, Camera, LiDAR, Infrared, etc.)

- Please explain what excites you about this role!
