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.

DEVELOPER ADVOCATE:
We’re looking for developers with great communication skills, to show people how to build awesome things with Anvil. You’ll be building example apps; writing how-to guides, blog posts and tutorials; presenting Anvil at conferences; and helping our users – from individual developers to huge tech companies – build their applications. And then you’ll help us work out how to improve Anvil for them.
It's rewarding work – developers love being introduced to Anvil (our stand is always crowded[0] at conferences!). Plus, there are all the advantages of a small startup: lots of autonomy and huge impact. You'll be working directly with the founders as well as some seriously talented colleagues.

We're bootstrapped and profitable, with a small, smart, friendly and diverse team.
Building dev tools is great! We're solving problems we've experienced ourselves, our customers are developers just like us, and platforms have the most fun engineering problems.

Subject: HN Sep 2025 - <Role>
No recruiters, please.
As one of our QA Engineers, you'll be the guardian of product excellence - thinking like a hacker, testing like a detective, and ensuring our complex systems work flawlessly in the wild. You'll go beyond finding bugs to anticipating the unexpected: edge cases, weird component interactions, and those "no user would ever do this... but what if?" scenarios that separate good products from great ones.
What You'll Own:
* Design battle-tested strategies that catch issues before customers do
* Build automated test suites that scale with our ambitions
* Hunt down bugs across complex component interactions and configurations
* Partner with dev teams to ship quality at speed
* Be the voice of risk assessment when it matters most
You Should Have:
* Critical thinking that connects dots others miss
* Deep web tech knowledge (HTTP/HTTPS, DNS, SSL/TLS, CDN)
* Automation chops (Python, JavaScript, Bash)
* Experience with test methodologies and writing bulletproof test cases
* Debugging skills that turn logs into insights
* Communication skills that turn complex issues into clear actions
Why Join?
You'll be testing cybersecurity products that defend critical infrastructure against DDoS attacks – a single bug could mean the difference between stopping an attack in <10 seconds or watching a bank, power grid, or hospital go offline. This isn't just QA – it's cyber defense at the highest level.
If breaking unbreakable systems and ensuring bulletproof security for critical infrastructure sounds like your kind of challenge, come lead, code, and conquer with us: https://www.link11.com/en/blog/jobs/qa-engineer-remote-first...

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

San Francisco (Dogpatch) | On-site w/ flexibility | Full-time | Multiple Roles, $120k–220k + equity + benefits
Why: Comms are contested. Radios make you a target, satellites aren’t guaranteed, and brittle legacy networks won’t survive future fights.
What: We’re building an autonomous maritime network — think distributed systems in the ocean—extending resilient comms, sensing and compute to the edge in high-threat remote environments.
Who we are looking for:
- Software Engineers: large-scale distributed systems, networking, system design, embedded software, DevOps rollouts. Python, C++, Rust. Bonus: SDR, mesh, security.
- Electrical Engineers: PCB layout, embedded, RF, circuits, power/batteries, electro-mechanical. Bonus: DSP.
- Marine/Mechanical Engineers: pressure vessels, subsea robotics, gliders, ruggedized design; DFM, reliability, field deployment.
You will: ship code to robots, test on the water, move fast, own big surface area, and work directly with military operators.
About Us: Our founding team includes a Navy SEAL veteran, defense industry engineers, builders, hackers, and watermen (sailors, boaters, divers, fishermen). We’re focused on real future missions — not legacy requirements. Venture-backed; public launch soon.
Eligibility for a TS/SCI security clearance is a plus. Please send a short note + resume/portfolio to jobs@reveredefense.co with subject HN – Engineering.
