Tech Stack:
Product (web app, API): React, MySQL, NodeJS, Python, AWS
Machine Learning: Python, PyTorch, AWS
* Scalable and tolerant systems using Kubernetes, Docker, and cloud infrastructure (GCP) * React, NextJS, PostgreSQL, Docker, Python, Javascript/Typescript. * Infrastructure: GCP/AWS, (Cloud Storage), running containers in production (Kubernetes, GCP GKE, GCP Cloud Run, AWS ECS, AWS EKS, AWS Fargate).
Stoke is a 5-month-old startup (founded in Feb 2025 by insuretech veterans with $4B+ in previous exits across 2 bootstrapped companies) building real-time Voice AI agents to make insurance purchases easier, faster, and more affordable.
PROBLEM: Insurance is a critical product, and the current system is broken. Policies are the main shield between American households and financial ruin. At 5% of income, it’s the fourth largest household expense after housing, transportation, and food. The majority of people have insufficient coverage and are paying too much for it. This is primarily driven by human agents who frequently have insufficient expertise and are driven by ~$200B a year in perverse incentives. Customers eat the costs of all of this through higher premiums.
SOLUTION: AI agents that enable personalized, unbiased, expert product recommendations at scale and at a fraction of the cost. We can simultaneously raise the bar of service while stripping out unnecessary costs, delivering those savings directly back to consumers in the form of lower premiums.
TEAM: 5 engineers (ex-Facebook, NYT, ScaleAI, AssuranceIQ), growing fast.
HIRING: Founding principal engineers/leaders with expertise in distributed systems, infra, real-time pipelines, agentic AI.
TASK: Shape architecture (AWS, Kafka, Python, Kubernetes, WebRTC); scale for 1000s of concurrent calls under 400ms latency; mentor as we hit 50+ engineers; directly help families save on premiums.
YOU: Obsess over reliable code, solve tough problems, ship fast, explain concepts clearly, learn quickly.
PERKS: Competitive salary/equity, full benefits, top tools, encouraged recharge time, quarterly retreats (hackathon + vacation).

We're a quantum computing non-profit organization, and we are looking for a full-stack web developer.
The job is classical — mostly building web portals — but those portals open into the quantum world.
Quantum computing knowledge is a plus, but not required. The initial project is a platform to understand the trajectory of quantum computing. The focus is on data visualization, so strong skills in that area are preferred. The candidate will work mostly alongside quantum engineers and researchers, so ownership to work independently on the classical side of things is important.
The stack of the main web project is PERN, but the organization maintains other projects in Python.

Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?
Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

I'm the cofounder of Krea (https://www.krea.ai), a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and creatives. Small team (~15); millions of active users; and we've raised over $83M from top silicon valley firms.
We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.
The job:
- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.
- Work with our research team to build ML pipelines and deploy models to make sense of raw data (example - find clean scenes within videos).
- Learn ML engineering from world-class researchers on a small tight-knit team. As you’re building data pipelines, you’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions of Krea users.

Saildrone is the world's leading collector of ocean related in situ data via uncrewed vehicle, above and below the sea surface. We work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, counting biomass to establish fishing quotas, or detecting and stopping illegal fishing and drug trafficking.
Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we recently completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just wrapped up a big demonstration for our partners in NATO[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand our planet.
Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.
In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.
You can see a list of open positions on our career page: https://www.saildrone.com/careers

Do you feel overwhelmed by the amount of stuff to learn? Do you have hundreds of books and articles in your to-read list, but wish you could extract the main ideas faster?
The goal of Shortform is to make the world's best ideas more accessible. We started by creating the world's best book guides, with in-depth chapter-by-chapter summaries, original insights building on the book, and distillation of ideas into actionables. They're like superpowered book summaries.
Our ultimate goal is to index every idea on Earth and make sense of it. Specifically, we want to summarize and contextualize every meaningful idea published each day, in every form of media (books, articles, podcasts, videos, news, research papers). Illustrative ideas include a news summarizer that shows the entire spectrum of opinions on a topic to help avoid polarization, and mini-courses that draw from the best sources across media to teach a topic (eg to learn negotiation, start with this book, then listen to this interview, then see these news articles for the principles at work, do these exercises).
If ideas like these interest you, please apply.
--------
Company status: We launched 6 years ago. Shortform was funded by the founder (who has built multiple bootstrapped profitable companies in the past) and has taken on no outside investment. Our financials allow us to be profitable, but currently we're reinvesting in growth. Engineering team consists of 10 full-stack engineers.
Technology: Vue.js on frontend, Flask / Python on backend, with heavy R&D in AI / LLM / GPT. (Keywords for searchers with tech flexibility: Angular, React, Django | BERT, LLaMA, Natural Language Processing / NLP, Large Language Models, ML)
About the role: Ideally you're fullstack on the web, and comfortable on both front-end and back-end. Position is remote (current team is worldwide). Fulltime roles preferred; hours negotiable for strong candidates. We're able to pay competitive market salaries (i.e. not decreased by equity).
Email jobs+engineerhn@shortform.com to get more details about the company, what we're building, and the application process. In your email, please discuss your experience for our stack, and also your favorite non-fiction book (to help us screen spam emails).

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
