ORFF Maestra | Prototype Developer; Technical Product Lead | REMOTE (US only) | Contract, part-time | https://orffmaestra.com

We're preparing a U.S. Department of Education SBIR Phase IA proposal to build an assessment reasoning platform for school speech-language pathologists. It implements TTL-MSM, a fully specified decision framework for one of the hardest calls in school eligibility evaluations: whether a student's communication profile reflects a disorder or a difference. Clinicians code each source of evidence, and a fixed rule combines them. The rules are written; the software isn't. The research lead is at Baylor University.

Prototype Developer ($70–95/hr): build a browser-based web app from a written spec, with privacy designed in from the start so it's ready for FERPA-protected student data later. About 15–20 hrs/week for nine months if funded.

Technical Product Lead ($75–100/hr): the bridge between the clinical spec and the engineering. Scope the prototype, turn the spec into requirements, and keep the build on schedule. About 5–8 hrs/week for nine months if funded.

Pre-award scoping (10–15 hrs for the developer, 5–10 for the lead) is unpaid, and funded work is contingent on award. U.S. citizens or permanent residents.

We are a funded and backed venture building the regulated base layer for tokenized commodities including the US-regulated trading venue, Mint and benchmarks, bridging institutional commodity markets and on-chain finance. Commodity markets trade tens of trillions a year on infrastructure designed for paper-based trading; we are what comes next. Launching Q1 2027.

Roles currently available:

VP of Engineering: owns the platform end to end, from on-chain contracts (Avalanche) to the trading engine, custody integrations and institutional-grade security and operations. A VP or SVP who still builds and ships, not one who just manages others; you will have a real say in the architecture before we finalize it and will work with leaders in tech and commodities. You must have done this before: delivered a trading venue or institutional token issuance, end to end. $200K to $300K base plus equity depending on experience and location.

Lead Product Manager: works with our partners and customers to ensure the launch product suite is fit for purpose and aligns participant experience across onboarding, trading, collateral and reporting. You must have shipped products in a regulated financial venue, exchange, clearing house or institutional crypto platform, you write the spec yourself, and you have run product through a regulator's questions. $150K to $240K base plus equity.

We hire on written replies and quality of CVs. We read every reply ourselves, so please write yours yourself. Send a short note on what you have built that is closest to the seat, with references, to careers@neo.co and put the role in the subject line. Please mention you came from HN.

We The Flywheel | Remote | Brand Identity Designer (AI-agent team) | Hourly, flexible hours

We build and run our own brands (race finders, training tools, AI guides, sports media) with a small remote team and a lot of AI agents.

Most of our brands have an identity that is good enough. We want someone with a sharp eye to make them good: logo refinements, lockups, favicons, social and OG images, colour and type rules. It's polish and judgment, not starting from scratch. Our agents do the digging, so you spend your time designing.

Please include identity work that is live somewhere. There's a short assessment, read by a person. https://wetheflywheel.com/en/careers/brand-product-designer/...

Bridge AI Consulting | AI Consultant, Junior AI Consultant | REMOTE (US) | Full-time | $60K–$100K base + upside for new business, equity possible | Visa sponsorship possible

We're a small, bootstrapped, profitable AI consulting firm. We embed with small and mid-size businesses (wealth management, real estate, construction, higher ed, nonprofits), learn how the work actually gets done, build what makes sense (mostly Claude: skills, agents, connectors, MCP) and train every person until they don't need us. We went from 1 client in February to about 20.

You'd own client relationships end to end: discovery, the build, the training. Strong builders who can also explain things to a 60-year-old business owner do very well here.

Shepherd (Series B) | ONSITE | San Francisco, CA

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.

The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.

We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.

We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!

We’re hiring for 2 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.

Check out our open roles here: https://shepherdinsurance.com/careers Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis – If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.

* In the form, be sure to mention that you heard about this opportunity via Hacker News. If you want to read more about our team and culture, check out our blog: https://shepherdinsurance.com/blog

University of Cambridge, University of Manchester | PhD in AI / Earth Observation / Environmental Science | ONSITE | UK home fee status only | £30k tax-free annual stipend

Our group at Cambridge works on Earth Observation foundation models (Tessera: v1 https://arxiv.org/abs/2506.20380, v2 https://arxiv.org/abs/2607.03949, https://geotessera.org/) and we've started a collaboration with Manchester to understand how they can be used to improve pollution models and then environmental decision making in general. This involves training new models and doing high-resolution inference across national or even global scales, as well as figuring out how to use that data to help policymakers make better decisions.

As part of this work we have a PhD studentship through the joint Manchester-Cambridge Centre for Doctoral Training for AI in Decision Making for Complex Systems. This involves one year at Manchester doing taught postgraduate study and then three years at Cambridge for the PhD.

Our work is all open source and involves solving significant compute and data challenges. Training our current-generation model takes ~250k GPU hours and a single year of global inference needs to move over 5.5 petabytes of data through the inference pipeline. This project would suit someone with strong machine learning and software engineering experience. We can help you build the atmospheric science and Earth Observation skills.

We are a highly collaborative group who spend our time not only on foundational research but also on developing applications with practitioners and decision makers. Our work sees use in many industrial, academic and government environments for problems like crop classification, tree species mapping and change detection.

You can find out more here: https://www.findaphd.com/phds/project/from-satellite-to-stre... - if you have questions about the project you can contact me, Sadiq Jaffer, at sj514@cam.ac.uk . For questions about the application process you'll want aidecisionscdt@manchester.ac.uk .

Application deadline is Friday 4th of December with a course start date of September 2027.

Simple Analytics | DevOps Engineer | REMOTE (worldwide, any timezone) | Full-time, 32h, 24h possible | €5,000/month (full-time) | https://www.simpleanalytics.com/jobs/devops

Hi HN, I'm Adriaan. Simple Analytics exists thanks to HN: it started with my Show HN in 2018 [1]. Today we're a self-funded, profitable team of four building privacy-first analytics.

Privacy is why we run our own bare-metal servers instead of the cloud. We're preparing for a LOT more traffic, and you'll own the infrastructure and its reliability. We have good documentation. First project: leading the infra side of our Elasticsearch to ClickHouse migration, with Alex, our developer.

Stack: Ansible, OpenTofu, Docker Compose, Grafana, GitHub Actions, TypeScript. Clear async communication matters more than knowing every tool.
