* Manifesto Manufacturing is important. It’s the fundamental industry on which everything else is built. We take it for granted. In 1989, 35% of the entire software industry was manufacturing systems. Back then, services, hand holding, customization, and consulting were necessary to get the systems to where they are today. What was the first massive burst in productivity from technology has stagnated into incremental diminishing returns and exponentially increasing complexity. We can only continue to add complexity for so much longer until the whole system collapses. "Any intelligent fool can make things bigger and more complex. It takes a touch of genius and a lot of courage to move in the opposite direction." Manufacturing is important. We must deliver a touch of technological genius to reintroduce simplicity, efficiency, and integration.

Jupiter Health | Program conversational AI | Unique data assets | Unstructured queries to a structured data answer Interested in working with a unique dataset in healthcare (HC)? We are an NY- and SF-based start-up making it easier to find direct pay healthcare, outside of the traditional insurance system. We are building the largest dataset of direct pay rates in the US. To help consumers find the right service, we need a conversational AI program that can get users from the unstructured ways that people begin to articulate their health needs (symptoms, needs, type of doctor, etc.), to the specific service from our dataset that they need by asking follow-ups and making the correct determination. E.g., from “I think I might have the flu” to a virtual urgent care visit, or from “I need an MRI” to an MRI of the chest, one view, with contrast. We are looking for a highly talented individual interested in this problem who can take it on for us. Please shoot us an email if that may be you! Email is hidden

Pasteur Labs (https://pasteurlabs.ai) | Full-time | REMOTE (worldwide) | DevOps / MLOps / full-stack / platform / MLEng

At Pasteur Labs, we develop computing technologies that enable scientific and industrial challenges to be approached in new ways: that is, a first of its kind AI-native, developer-first platform for modeling & simulation (M&S). Our product aim is to enable in-silico playgrounds for human-machine teams experimenting and building in industrial R&D, energy security, & advanced manufacturing arenas. As a public-benefit for-profit startup, our mission is Nobel-Turing [1] technologies to advance science and society for all humankind. With venture funding and Fortune500 customers (+dozens more on the waitlist), we’re looking for ambitious, intellectually curious software engineers that can consistently contribute in non-trivial, impressive ways as we ship and scale our flagship product platform — some call it “live intelligent digital twins” and others say “cyberphysical testbeds for AGI”, while most view Pasteur Labs product catalogue as “Databricks for industrial R&D”.

--> https://pasteurlabs.ai/careers/ <-- While we don’t list requirements for degrees or years-experience, everyone needs to demonstrate high-caliber engineering and problem-solving; we’re dedicated to scientific rigor and robust engineering for complex and dynamic environments, so prove to us that you not only fit in but that you can make us better. In particular, we are seeking experienced DevOps / MLOps teammates that can build from day 1 with Go, Python, containerization, and our multiple cloud setups (Azure, Google (GCP), Oracle Cloud (OCI)), and on-prem infrastructure for mixed GPU & CPU workloads — if you've done this before with CAE simulation systems and scientific datasets, reach out and say so!

Our team is largely made of industry-hardened research-software engineering experts [2], whom thrive in interdisciplinary and fast-paced teams—from NASA to Nvidia, Deepmind to Oracle, CERN to Cerebras, SpaceX to Autodesk, the Navy, Air Force, and on. With HQ in Brooklyn NY [3], and satellite offices opening in Copenhagen + London + Vancouver in 2025, we are an internationally distributed team running remote full-time — from San Francisco to Sao Paulo to Stockholm and everywhere in-between. The full team gathers multiple times per year for 1-week Pasteur Labs “onsites”—recently in Miami, Amsterdam, Cambridge, and more.

Stealth | San Francisco, CA (hybrid: M-W-F ONSITE) | Full-time | Fullstack Engineer

We're looking for a backend-leaning fullstack dev. Highlights:

- We're a 5-person startup in San Francisco (hybrid: 3 days/week in office)

- We're working on a b2b SaaS for managing/analyzing cloud costs for really large companies.

- The domain isn't cool, but the complexity is fractal and the need is huge.

- Typescript/Python/Clickhouse currently

- Our founders are also the founders of the Duckbill Group, an AWS cost consultancy. As a result, we've got a great, built-in sales pipeline.

- As a result of that, we're bottlenecked on our ability to just build the features our users clearly want.

- So we're hiring a 4th engineer: a backend-leaning full stack dev to build and own large swaths of this thing we're creating!

- We're looking for someone with 5+ years of experience, though probably closer to 8-10, depending on the person and the experience.

- Comp is 175k-200k base, 0.5-0.75% equity.
