Gauge helps companies show up in more AI answers. Search traffic is shifting away from Google into AI chat, and companies are figuring out how to adapt right now. Our system delivers real-time analytics derived from millions of LLM answers, while providing an intuitive, powerful UX. We also generate optimized articles to improve our customers’ visibility, and offer an agentic chat interface over their data (think ‘Why was there a spike on 12/10?’ or ‘Which of my pages should I refresh?’).
I'm Evan, the CTO, and we're looking for engineers with strong programming fundamentals, creative problem solving skills, and a high-agency working style. You might be a good fit if you are an ex-founder, ex-founding engineer, or have worked at a Seed/Series A startup.
We primarily use Django, React, Postgres, Celery, and Clickhouse.
Contact me with your resume (and mention HN) if you're interested: evan[at]withgauge.com

Pango is building the world's first Agentic Operating System for e-commerce logistics. Our vision is to create the AI e-commerce employee of the future. We are forming our core team in Stockholm and are looking for exceptional engineers. We are based at the SSE Business Lab, where companies such as Klarna, Voi, Budbee or Legora originated. We have achieved a product-market fit and are growing rapidly.
You are a good fit if:
* You are comfortable maintaining, expanding and operating an entire B2B SaaS platform with a high sense of ownership.
* You are happy to take on work that in a large company is divided into a dozen roles, and execute it all at a good enough level.
* You are unafraid of any technology. If we need a desktop app and you haven't done one before, you will study the documentation of Electron.js and build one. If a model for predicting delivery times is needed, you will do a literature review to find the right architecture and train one.
* You have strong proficiency in any backend language or platform, with a strong willingness to dive deep into PHP/Laravel OR strong proficiency in JS/React.
* E-commerce (Shopify, Magento, other platforms, shipping carrier integrations) experience is a plus.
You will take a key role in shaping the product and company, with ability to make an impact and advance career limited only by your aptitude and interest.
Reach out to lukasz@pango.ai if you are interested or have any questions. We review applications immediately and move quickly.
Our mission is to make it normal, not heroic, for edge AI, mobile apps, and critical software to run close to where data is born: on devices, in vehicles, in field hardware, not just in a distant GPU farm. We’re building the data and trust layer that lets developers ship systems that still behave correctly when links are flaky, latency is awful, and the cloud is optional instead of mandatory—instead of the usual “SQLite everywhere + ad-hoc sync” duct tape.
We’re growing fast and are looking to fill the following positions:
-Chief of Staff - https://source.network/careers/chief-of-staff
-Lead Edge AI Engineer - https://source.network/careers/lead-edge-ai-engineer

We are a team of 25 with experience at companies such as Google, Meta, Stack Overflow, Rippling, Snowflake, Confluent and Kaggle.

Hey! I’m Maxim, cofounder/CEO of Immunera.
We're building blood tests that use gene sequencing and machine learning to help patients with autoimmune disease. Immunera spun out of years of research at Stanford, and our technology has been published in Science and covered by The New York Times.
We're hiring a Principal Machine Learning Engineer to shape the core models and infrastructure that power our blood tests. We are partnering with hospitals to generate training data from real patients for our language models and other biological sequence models.
This is a senior engineering role with significant autonomy at an early-stage, venture-backed startup. We're looking for strong experience building and operating ML systems in production (Python, PyTorch/TensorFlow, cloud platforms). Prior biology or healthcare experience is NOT required; we care much more about your ability to reason about data, models, and systems.
