I'm Manu, founder of Hyperspell. 14 Years ago I found my first job in tech through Who's Hiring. I take this job board seriously :)
Hyperspell is building Context & Memory for AI agents. We're at the intersection of "future of AI and agentic computing" and "this actually works". We're not just changing how our customers use AI in their products, but are constantly iterating on how we use AI to build Hyperspell, and what it means to be a software company in the decades to come.
We're hiring product, AI, and Platform Engineers in SF: https://jobs.ashbyhq.com/hyperspell
Comment or reach out to founders@hyperspell.com with any questions!
i feel like this needs a joking nod to the complaints of llms constantly responding with not just x, but y
Preferred Networks is an AI company based in Tokyo working across the stack, from AI chips and computing infrastructure to LLMs and products. You may already know us indirectly if you've used software we've built, such as Optuna or CuPy (or Chainer, back in the day).

- LLM Inference Optimization Engineer: Improve the inference engine powering our API service and maintain PLaMo implementations in open source projects such as vLLM. [Apply here: https://open.talentio.com/r/1/c/preferred/pages/119173]
Both roles require relocation to Japan. We are happy to provide visa and relocation support.

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds and still coding. Notable recent projects include internal tools for Anduril, and the original buildout (both auction site and operations infrastructure) of Voltage Park. This is a remote-first agency, but some projects involve onsite work.
I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.
Applicants must meet a high bar - I personally review every hire. In return you’ll get:
* Flexibility and a low-bureaucracy environment
* Clients that won’t treat the vendor like “the B Team”
* The chance to act as a code architect, not just implement tickets
* Exposure to a wide variety of industries and modern challenges
* Me as your personal champion and advocate
We’re currently especially seeking:
Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)
Tier 3 roles are typically 5-10 years experience with $150-$180K total comp.
Tier 4 roles are 11-20 years experience, $215-$260K total comp
(Higher tiers exist, and we always welcome exceptional applications.)
Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled. Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate.
Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.
Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.
This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.
We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.
Reach out directly with your gh, linkedin, and resume and why you want this position to lucie@markerlearning.com. Please specify your location, if you are interested in full time, contract or open to both. Make the subject "Founding Engineer Application (I am not a bot)".
