We are doing this intentionally to filter out people that apply just based on company name. We'd prefer people that apply based on job interest and relevant experience.
We're an applied research company building autonomous, collaborative, and socially intelligent agents. Our small team includes computational neuroscientists, AI researchers, engineers, and builders from MIT EECS, Stanford NLP Group, Google X, Citadel, and beyond.
Our latest product, tryshortcut.ai, just launched over the summer to amazing reception and we’re just getting started.
We…
...do everything from sophisticated Agent orchestration to SFT/RL post-training of foundation models.
...have an organizational structure where product leaders are given great autonomy to experiment and ship fast.
...compensate well above market and provide generous equity.
We’re looking for:
—> Machine Learning Engineers + Applied Research Engineers to bring our research to life.
—> Engineers and ex-founders to build Agent-first products.
—> Researchers to develop frontier technologies in the Agents domain.

As an open source contributor to claude-flow and claude-swarm, I've worked on systems where specialized agents (Queen orchestrator, Workers, Scouts, Guardians, Architects) collaborate through: - Task orchestration with decomposition, distribution, and progress aggregation - Consensus protocols with voting and tie-breaking for strategic decisions - Shared memory enabling collective learning and pattern recognition - Real-time coordination with auto-scaling, load balancing, and fault tolerance - Self-healing mechanisms that rebalance and recover from failures
This hive-mind approach demonstrates how agent collectives can achieve what isolated agents cannot: parallel problem-solving, emergent intelligence, and robust execution at scale. The probabilistic nature of LLMs—often seen as a limitation—becomes an asset when simulating the inherent unpredictability of human social systems.
I'm eager to contribute to teams working on agent societies, emergence, and collective intelligence. GitHub: https://github.com/Tar-ive
We build clinical AI that empowers hospitals to analyze the complete record of every patient to fully capture the value of care delivered. Founded by physicians in 2020, our proprietary AI platform understands the nuances of clinical reasoning, enabling hospitals to accurately reflect every patient visit for fair reimbursement. By doing so, hospitals can recover millions in earned revenue, enhance care outcome and quality metrics, and optimize healthcare operations.
The current team is very high functioning (MD + data scientist combos, former ASF board member, Google and Amazon engineers, Stanford LLM researchers, etc.) and initially scaled the company to $1MM+ in contracted revenue without raising capital.
SmarterDx recently became part of Smarter Technologies as part of a $1.1B deal by New Mountain Capital, a leading growth-oriented investment firm. We have been backed by top investors including Floodgate (Lyft, Twitch, Twitter), Transformation Capital, and Bessemer for a total of $71M, including our $50M Series B, and are experiencing an incredible growth trajectory customer and revenue wise with no signs of slowing down with 150% YoY headcount growth! This time last year, we were at ~110 employees, and are above 280 as of today!
We are looking for: Security Engineering Manager - Staff and Senior SWEs, Full Stack and Backend focused - Staff ML Engineers - Data Science Managers - Staff Data Scientists - Senior Data Analysts - Senior Product Managers - More!
We have PMF, and it's time to scale! For more and to apply, see https://smarterdx.com/careers
I have a lot of experience (5 years) building and optimizing data pipelines from diverse sources using Python, SQL, Snowflake, and AWS Aurora that supported compliance and performance monitoring. I live in San Francisco and can start immediately.
We aren't actually hiring anyone immediately, but we've hired a handful of great engineers from HN and inevitably will need to hire again. We've found having those conversations and keeping in touch is much better than going through the process from scratch each time, as it fast tracks the process a great deal when the time comes. So reach out if you think you're a good fit.
ReciPal is a profitable, growing, bootstrapped, and (have always been a) fully remote company (based in New York) with 6 full-time employees. We make simple software for food businesses - nutrition analysis and labeling, costing, and inventory management. We've been around for almost 15 years now!
You'd be working directly with me, solo founder, our senior engineers, and marketing and support colleagues, and hopefully take on a growing role over time to treat the business like your own. It's a very low key work environment, but independent and plenty of responsibility and ownership for the right person.
Stack includes Rails 8, JavaScript, Postgres, Heroku.

At Strum, we're reimagining technology that powers global supply chain using a fresh AI-first approach. Most supply chains are still stuck with Excel or enterprise tools that take months (and $MM) to adopt. Our mission is to lower that barrier — making it possible for any business, big or small, to access modern forecasting, inventory, and planning solutions in days, not months. We’re on our journey to democratizing supply chain technology. As our first engineer, you’ll be working with the founders (former Supply chain/tech directors at Amazon who have built key components of Amazon's supply chain) to develop the core product from the grounds up (involves application of LLMs, deep learning, and optimization). If you have mid to senior level experience in software development, have built SaaS applications, understand ML-Engineering, and love building 0->1 products, we would love to talk to you. Please reach out to us at: careers@strum-ai.com.
Location negotiable.
We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.
This is a rare opportunity for senior engineers and product managers to join us at a pivotal moment and shape a deep-tech product from its earliest stage:
* Program Synthesis Engineer
* Product Software Engineer
* Bayesian Software Engineer
* Senior Product Manager

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re hiring on the backend to help solve one of the hardest problems in data engineering: building a production knowledge graph from millions of fragmented, inconsistent Chinese corporate records where traditional approaches break down. Our PySpark/EMR/Airflow pipeline is just the foundation. The real challenges are in entity resolution across transliterated names and obfuscated ownership structures, bipartite matching algorithms and inferring relationships. We build our product on top of that with a Django/FastAPI/React stack to help our users access that knowledge graph to analyze and investigate any risks they should be aware of.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
Apply here: https://jobs.ashbyhq.com/wirescreen/158fd72f-fc2f-47a3-bdb5-...
Happy to answer any questions - you can reach out to me here or at leo.green@wirescreen.ai - I'm a recruiter with WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.
