Ask HN: Who is hiring? (December 2025)

Freeform (http://freeform.co ) | Software Engineers | Full-time | Onsite | Hawthorne, CA (Los Angeles County)

Freeform is deploying metal 3D printing factories at global scale and setting a new frontier in manufacturing. With AI, GPUs, and FPGAs working in tandem, our system monitors and corrects every microsecond of the process, delivering a level of precision, speed, and quality that’s never been possible—until now. This isn’t just an improvement; it’s a leap forward in how complex metal parts are made, with the ability to revolutionize industries like aerospace, defense, automotive, energy, and beyond. We are backed by top VCs including NVIDIA’s NVentures, Founders Fund, and Threshold Ventures.

It’s a small, tight-knit team and you’d have the opportunity to own significant and impactful greenfield projects throughout the entire development lifecycle and much more. Our software team comes from the likes of Google, SpaceX, and Apple, and believe in taking a first principles approach to solving hard problems.

foam.ai | Founding Engineer | $180-$300k | 0.25%-2% | SF (onsite) | Full Time

foam is building a new observability stack that captures, traces, and links everything, purpose-built for AI. We use this foundation to feed complete context into AI to automatically identify and root-cause breakages across entire systems.

* We’re a five person team. Perla (CEO) was the 5th engineer in the consumer facing team at Affirm (pre-IPO).

* We've raised $9.9M in seed funding from Khosla Ventures, Max Levchin, The House Fund, and South Park Commons

* We’ve got active betas at Orb, Braintrust, Plaid & TogetherAI.

We’re looking for engineers who want to take point and work hand in hand with Perla on one or more of our core systems:

1. The Telemetry Engine - Think of this as a major extension of OTEL custom built to capture signals that have historically been inaccessible to humans.

2. The Root Cause Analysis Engine (aka Solver) - This is currently an agent swarm, but evolves every week in search of better and better root cause analysis.

If putting an end to awful on-calls and building a system that can deliver self-healing software is exciting to you, send an email to luke -at- foam dot ai with your resume and mention you came from HN.

Updated to reflect our strong preference for US/CA. We have made exceptions in the past.

Since there are comments about this above, I want to highlight that we've hired successfully on HN for several roles for our current small team. We hired 1 of 2 roles last month, and are still looking for a candidate for this role, which is why I'm posting here again.

I don’t think this fits the spirit of this monthly post. This is not “hiring”, it’s paying people for training data to automate themselves out of a job

will update, thanks
