Carbon AI | Founding Eng | Remote-first (US) | https://carboncre.ai/
- Product: AI-automated commercial real estate workflows to tackle necessary but mind-numbing tasks that human analysts typically perform.
- Funding. $4m seed round from Bling Capital, who also funded the last startup my cofounder and I created in the same space (exited to Built Technologies, which represents 10% of all US construction spend)
- Traction. We’re still building out the product, but have design partnerships with 4 prominent firms in our space, who together comprise 25% of the market we’re targeting.
- Team. You'd be joining as Eng #2 to pair with our Founding AI Eng. In addition to me and my cofounder, Josh, we also have 3 ex-Google/Uber contractors helping us build faster. Our plan is to transition all development in-house though.
- Tech stack. TypeScript, React, NodeJS, Express, GraphQL, Postgres
- Comp. $175-225k base + above-market equity.
Note that while this is a remote-first role, we value having some in-person collaboration so we’d be looking for you to visit our office in Philly ~1x/month.

Drone startup | Product Engineer (Typescript) | 1 day/week in the office (London, UK) | Citizens of the UNITED KINGDOM only
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: hn-july25@mail.orth.uk with your CV and some personalised information about why you'd be the right fit.

Looking for a founding engineer to help us go 0→1. You’ll own architecture, ship fast, and build agent-based features with LLMs. Full-stack or backend-leaning ideal. You like product. You’ve built things. You want real ownership. You care about solving problems that actually matter.
Culture is low-ego, high-autonomy. Equity is meaningful.
