Censys | Senior SRE & Staff Software Engineer Roles | Full Time | Remote US

Hey everyone. I'm a Principal Engineer at Censys. We are the source for Internet Intelligence. We conduct a full internet survey every day and turn that into actionable data for folks to identify risk, research emerging internet threats, and make the internet a safer place. If you also get a bunch of data breach mailers in your mail box every year, you're familiar with the impact of security breaches at tech companies. We're trying to put a stop to that by helping companies understand their risk and mitigate it.

HQ is in Ann Arbor, MI, but we're all over the US. We're looking for a Senior SRE to help improve reliability and developer experience, and a Staff Software Engineer to join our Attack Surface Management product team. If you're a little bit more senior or junior than either of the postings, please do still apply. We care a lot more about getting the right people than we do matching the level exactly to the posting.

Please please apply to these role if:

- You can take ownership of improving a part of the product (Staff SWE) or the application platform we build for product engineers (SRE).

- You're game to navigate the messy middle of a small, nimble company with really high customer expectations. You'll have to navigate some ambiguity to be successful in either of these roles - don't expect pristine PRDs coming down from on high.

Our application stack is primarily Go and TypeScript with some seasoning of Python here and there where appropriate. Our primary cloud is in GCP and we also maintain our own physical servers (prior experience with physical hardware is great, but not required).

The links below will cause you to show up as a social referral from me. Feel free to reach out to me directly on Linked In (https://www.linkedin.com/in/farmdawgnation/) with any questions.

We've built a category-defining product and are now gearing up to scale. We're looking for our third Product Manager to help shape the future of our platform.

We're well-funded by top investors (First Round plus more to be announced), fully distributed, and known (and recognized) for building intentional, inclusive culture. We offer competitive global rates (SF salary + equity), equal pay by level, and comprehensive, family-friendly benefits.

Komodo Health | Applied AI Engineer | Full-Time | $200-$253k + equity... | SF/NY Once-a-month-few-days / Remote US. Can sponsor.

Healthcare in the U.S. is a mess. Komodo Health is fixing that—with data. We’ve mapped the patient journey across the country to build the most complete picture of disease burden and treatment gaps. Our customers are pharma, payers, and health systems who actually want to do something meaningful with that information.

We have an exciting product, marmot, that is AI-native, both in the interface as well as in development, and want to carefully grow high productivity teams around this offering. AI integrated with Komodo's data is giving some of the most unique, real world insights any of us has seen come out of the new LLM era. Our product was just featured on Times Sqaure too! https://www.linkedin.com/posts/komodo-health_last-week-our-d...

We are looking for highly independent individuals, who can work in a new, small, but empowered team. What will you be bringing? - Proven experience working on Agentic systems that solve real problems OR Some evidence you have the "instinct" Andrew Ng mentions as the differentiators of successful Agent builders. We also take full ownership of the product, so experience+readiness for fullstack development is a must. Core ML experience is not required and for this position, not relevant at all. The new LLM/Agent era is... different.

Perks will include annual conference trip, periodic travel to SF/NY for on-site, Executive Coaching, etc.

If this post sounds exciting, please apply at https://job-boards.greenhouse.io/komodohealth/jobs/806961600... (mention HN as the source). Please note, we can only consider applicants who are already in the US.

If you wish, please also email me at ramraj.velmurugan@komodohealth.com with an example of how you have figured out that instinct I mention above.

Y Combinator (yes, the people who run this site) | Full stack web and AI | San Francisco | Onsite | Fulltime

YC itself hires software engineers from time to time. Many people don't know that YC has a small but very important software team. We run several websites - not just this one, but also workatastartup.com (the main way YC companies hire), a social network for YC founders, and the core infrastructure that YC itself runs on.

Recently, we've been spending most of our time building our own AI agents. Over the last year, YC has mostly funded AI agent companies, so it's been cool to go really deep building our own AI agents too. We're building agents to automate every aspect of what we do, and pushing the limits of what's possible with the current models to do it.

An unusual aspect of being on the YC software team is that you'll get full access to the YC program, founders and partners. The YC batch runs in the same building we work out of, so there are talks with famous founders happening most nights, right downstairs in our building. If you want to start a startup someday, working at YC would be an excellent jumping off point - several YC companies have come from team members who decided to start their own company.

YC works fully in-person in SF. We're happy to help you move here if you're in the US already. Unfortunately we can't sponsor new visas, but we're happy to transfer existing ones.

YC offers highly competitive compensation and benefits.

Friendly Captcha | Data Engineer - Bot Protection | REMOTE within EU | PART-TIME or FULL-TIME | Office in Munich, Germany | https://friendlycaptcha.com

At our scale we are looking for generalists more than specialists. The role is more about enabling for easy experimentation, data exploration and being creative in anti-bot approaches, than building the perfect ETL pipeline.

Our engineering team is fully remote across Europe, we meet up in person a few times per year. You can work either 4 or 5 days per week, fully remote or (partially) from our Munich office. Please note that we ONLY consider candidates located within the EU/UK/EEA/Switzerland.

Strum AI | Founding/Lead Engineer | https://www.linkedin.com/company/strum-ai/

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.
