We @diabrowser are hiring Prompt Engineers! Slop cannon. Vibecoder. Prototyper. Product Eng. PM. We don’t know what to call this role exactly. The official title is the Model Behavior team, We previously called it the Prompt Engineering team, but widened to cover more areas since we move around so much. It’s a job that changes every week and you get to make up, as you define and build the frontier of technology We have 2 roles - One is more Engineering focused This is not an average engineering role, you will be focused more on designing and building early ideas & quick prototypes. Working with many teams across the company. You should be comfortable independently shipping production features end-to-end in enterprise scale codebases. You'll live at bleeding edge of AI, prompting, harness design, tools, MCPs, memory, evals, and pushing towards whatever comes next. - One is more Product focused, and open to other backgrounds. We hire all sorts of creatives, artists, designers & technologists at BCNY. I encourage you to apply even if you don't consider yourself “technical staff” or don't fit traditional tech company roles exactly. We are looking to build a team of the best Prompters in the world. If you enjoy tinkering with AI all day, come join us as we reinvent the internet and modern work! You'll be working closely alongside myself and @jonathan_jlo, our leadership team @tfeener @jedimody , @hursh , @joshm and many others If this sounds like you, apply here and/or reply to this post

on top of being intense GEPA users, big surprise from @jedimody’s talk on the AI engineering behind @browsercompany’s Arc and Dia browsers is they’re intensely aware of @simonw’s Lethal Trifecta, and designing their Agentic browser to have security in mind!

New prototyping role just opened @browsercompany. TL;DR - we're getting pitched new APIs, models, etc. all the time, and want someone to be on the frontlines of de-risking what makes most sense for @diabrowser. Working closely with me! DM or email josh@thebrowser.company

Today, The Browser Company of New York is entering into an agreement to be acquired by Atlassian for $610M in an all-cash transaction. We will operate independently, with Dia as our focus. Our objective is to bring Dia to the masses. 🔗 More details from our team below

Here's what @browsercompany's AI eng & ML teams are working on for @diabrowser right now: (This is a pitch to come work for us; info at end) 🤖 COMPUTER USE – we've built our own bespoke APIs on top of Chromium to optimize latency, accuracy, and cost of computer-using agents. Demo attached. Big breakthroughs here in recent weeks. 🛡️ ON-DEVICE MODELS – we've built our own custom infra to run everything from encoder-only models to full LLMs on device. It's cross-platform, supports LoRa adapters, and optimized for the GPU. This system preserves privacy and enables fast inference times. 🧠 MEMORY – with your permission, Dia automatically tailors your AI experiences to you, personally, based on the tabs you open while browsing normally every day. We're also bringing vertical memory to specific features. ♻️ DATA FLYWHEELS – our Fall/Winter P0 is to double-down on training custom models based on implicit signals from daily use of Dia. Dia should get smarter and more useful the more people use it. Whether via RL, auto-generated prompts, or otherwise. If this work sounds interesting to you please visit our jobs page or email careers@thebrowser.company. Hiring nearly every related role -- from ML engineers to people prototyping with AI and context/prompt writers -- everyone encouraged to apply!!
