New Lantern | https://newlantern.ai | Software engineers (infrastructure engineers & backend-leaning product engineers) | Full time in San Francisco, CA (ONSITE)

New Lantern is hiring software engineers to help build an AI copilot [1] for radiologists.

Radiologists are experts at diagnosing disease in medical images, but they spend the majority of their working hours on tasks that have nothing to do with diagnosis: reading prior reports, transcribing handwritten notes, taking manual measurements, dictating reports, and chasing down follow-ups. New Lantern is building an AI copilot for radiologists to automate this non-diagnostic work, so radiologists can focus on the diagnostic & patient care work they love the most.

We are starting to find product-market fit and recently raised a $19M Series A from Benchmark [2]. Demand for our product is growing, and we're hiring software engineers in San Francisco to help us scale our product and our team. We work together in person five days a week from our office in Jackson Square.

Engineering is at the heart of New Lantern. Our engineers work directly with our founder/CEO, our staff radiologist, and our end users to build features that radiologists rely on daily. Everyone has real ownership and autonomy, moves quickly, and ships meaningful work frequently. We're a small, sharp team of frontend, full-stack, and backend engineers building a React-based web app backed by Python services, cloud infrastructure, and LLMs.

We're hiring for several engineering roles but top of mind right now is a Senior+ (ideally Staff-level) Infrastructure Engineer. We're looking for someone who's excited to help our team go from 0.25->1 on observability, availability/reliability, and scalable & easily deployed infrastructure to help us grow to meet customer demand. Once we level up our infrastructure, this team member will be instrumental in helping us build towards very high availability and reliability systems that enable high product development velocity.

I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN Email is hidden.

[1] We translate "AI copilot" to "AI radiology resident" when we speak with medical professionals, but the former is the clearest way to communicate what we're building here.

PostMatch.io | Growth Hacker/Marketing/Sales | Remote (USA/Canada) | Contract to Fulltime | Equity

I’m building a SaaS product with PMF already solved and a clear roadmap. Competitor traction shows there’s plenty of room in the space, and I’m looking for marketers and growth hackers to help secure customers and drive growth.

Product is almost ready, probably 3-7 days.

You’d be a great fit if you:

Know how to acquire early customers in B2B SaaS

Thrive on creative, low-cost growth tactics (organic + paid)

Enjoy working lean and iterating quickly

We’ll need to operate lean in the beginning, but once revenue starts flowing, there will be budget for paid channels and ads to help scale further.

I’m open to trialing potential partners on a commission basis, and if we’re a good fit and see results, I’m ready to discuss a strategic equity partnership.

Let’s connect if you’re excited to help take a SaaS business from early traction to serious growth.
