I'm Caleb, co-founder/CTO. VALIS builds data products for scrap metal recyclers. Our VALI-Sample devices image, weigh, and classify scrap, and our platform turns that into production and quality analytics 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 from a blank page: production tracking and analytics for recycling plants. 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+ years of experience, strong data modeling fundamentals, and like owning ambiguous problems end to end. We care more about how you think than what exactly you've used. Recycling, ERP/MES, or ops software experience is a plus.
Our stack: React/TypeScript, C#/.NET, PostgreSQL, AWS.
US work authorization required; no sponsorship.

We're looking for a passionate SWE with some linux/networking/firmware experience to drive forward some greenfield product development and help scale & deliver existing hardware-enabled offerings. We've got some scale-integrated cameras deployed in the field which enables a web-app for analytics for material sampling. We've got a few units deployed at metal recycling facilities, and we're ramping up sales. We're also building a camera-over-conveyor-belt solution for process monitoring (greenfield dev/R&D).
Desired Competencies: linux, networking, basic electronics, firmware, cloud infra (AWS), web products, databases
Nice-to-Have Experience: edge-to-cloud CV system deployment/design, .NET ecosystem (C#, EF), networking (Wireguard, ssh), firmware dev/mgmt, observability (OpenTelemetry, Prometheus), IaC (Pulumi), stats/math/ML/signal-processing fundamentals, basic soldering, web products (TypeScript, React)
Role is remote-first hybrid. For some hardware/firmware/R&D, you'll need to be in-person in Worcester MA, but majority of role is remote. Infrequent travel to recycling facilities (continental US) for deployment/maintenance will be required.
Apply here - https://apply.workable.com/valis-insights-1/j/A937EAA712/ We read and review every application. Please mention "HN" in one of the written responses.

I'm the co-founder and CTO of VALIS, a B2B SaaS company delivering software solutions to the metals recycling industry. Our goal is to reduce global carbon emissions through maximizing the recovery of metals through recycling, which requires a fraction of the energy compared to mining and primary metals production. We're a seed-stage startup, backed by leading climate-tech VC's.
Product-wise, we integrate recycling processes, equipment/sensors, production, and procurement/sales data to deliver an insights platform that helps metals recovery facilities optimize their processes. We employ a strong, domain-driven design approach to building our product. We're looking for execution-focused engineers to join our team and deliver complex features with autonomy.
We're currently hiring for two roles:
Senior Backend Engineer - https://apply.workable.com/valis-insights-1/j/4745C9DC32/
Full-Stack Engineer - https://apply.workable.com/valis-insights-1/j/3A06E4C40A/
