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.

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have >2000 organizations using our product.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

At Friendly Captcha we do one thing and we do it well: we protect websites from malicious actors and bots.
We provide privacy-friendly and accessible anti-bot solutions that don’t annoy users with tasks like clicking fire hydrants. We make the internet a bit better every day by winning over customers currently using Google reCAPTCHA.
We’re a growing, profitable, fully bootstrapped company. Our revenue mostly comes from medium to large European enterprise and governments.
We’re looking for an engineer whose focus will be on using data to improve our bot detection and protection. Telling apart bots from genuine users is vital to our product.
If possible, we prefer to keep things simple (perhaps boring is the right word even?) - choosing an if/else rule over a neural network. Good knowledge of the web is always useful in this company. 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.
Stack: Golang | Typescript | Clickhouse | Postgres | Redis | Python data science stack
