Polymath builds AI agents that read engineering drawings, generate CAD models, and rebuild parts across CAD systems. We're VC-backed, Harvard- and Stanford-founded, in production with our first product, and running pilots with Fortune 100 manufacturers in aerospace and consumer hardware.

We're hiring our first dedicated full-stack engineer to own the product stack end to end: the chat UIs inside CAD (TypeScript/React over MCP and REST), the Python/FastAPI services behind them (auth, job orchestration, metered billing with Auth0 and Stripe), and the pipeline that packages and deploys it all. You report to the CEO, join customer calls, and set the standards for the next ten hires.

Looking for: 5+ years running production web apps with ownership across front end, API, and deployment; prior early-stage experience (first 50 engineers somewhere); TypeScript and Python; shipped on AWS or GCP with Terraform/CloudFormation and Kubernetes/ECS/Cloud Run. Nice to have: LLM product ops, enterprise SSO, C#/C++ desktop packaging, any CAD or mech-eng curiosity.

Must be authorized to work in the U.S. Immediate start.

Apply: email careers@polymathmade.com with a resume, a GitHub or portfolio link if you have one, and a few sentences on a system you built and ran in production. I read every application and reply within a week. Full JD: https://polymath-ai.notion.site/careers-1

VALIS (Valis Insights) | Software Engineer, new product line | REMOTE (US, East Coast hours) | Full-time | $125k-$155k + equity

I'm Caleb, co-founder/CTO. VALIS builds data products for scrap metal recyclers. Our product images, weighs, and classifies scrap metal, and our platform turns that into actionable quality analytics to improve physical ops at plants across the US. Recycled metal takes a fraction of the energy of mined metal, and better data means more of it gets recovered.

We're hiring an engineer to build our next product line: a production tracking and analytics platform for recycling plants, extended from our existing product. We're a small team (<10 ppl). What you'd work on (ideate, build, deploy, own):

- Modeling a complex (and intellectually stimulating) physical process

- Agentic features that dig through production and quality data, surface trends, flag anomalies, and notify the right people

- Working directly with customers: regular calls with operators and plant managers, plus a few site visits a year

You should have 3+ YoE, strong data modeling fundamentals, and enjoy owning ambiguous problems end to end. We care more about how you think than what exactly you've used. Recycling, ERP/MES, or physical ops software experience is a plus.

Our stack: React/TypeScript, C#/.NET, PostgreSQL, AWS.

US work authorization required; no sponsorship.

Curiosity Studio builds internal apps and agents from a plain description, on a company's connected data and inside its permissions. It runs on premises or in a private cloud, with any LLM. We're bootstrapped, profitable and based in Munich. Our customers are large industrial and regulated companies, Airbus among them, and Studio has 30TB+ of data connected in production.

We are starting a team in Toulouse that works at customer sites, in French and English, along with the engineers who build Studio.

Forward Deployed Engineer: take a customer's problem from the first workshop to production. You decide with them what Studio should build, connect their systems, model the data as a graph, and oversee the C#/.NET connectors and services it needs. You also ship features and agents on top.

DevOps Architect: Own deployments in customer environments, from the first technical discussion to handover, on private clouds or data centers. Networking, IAM, Linux, Docker, monitoring, backups, upgrades, incidents. You also write code alongside the forward deployed engineers.

We're looking for hands-on builders who enjoy working directly with customers. Full-stack project experience preferred. Fluent French and English required.

Interviews: a 30 minute call, a technical conversation, then the founders.
