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.

SENIOR DEVELOPER:
We’re looking for an experienced all-rounder to work on the core Anvil platform, with a focus on the back-end. Our stack is mostly Clojure, Javascript, Python, Postgres, and container tools – but we're looking for someone who isn't afraid to jump into something you haven't used before.
You’ll be working with other seriously good all-rounders, including the founders (relevant PhDs, kernel contributors, built a dancing fountain for fun, that sort of thing) and senior colleagues (eg: Stu went from teaching Python in maths class to reverse-engineering our drag'n'drop editor in months), as well as our other developers and developer advocates. 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.

We're bootstrapped and profitable, with customers ranging from tiny (one-person startups) to enormous (HSBC, Bayer, Deloitte, etc).
We work hybrid (in the office Tue-Thu, wherever you like Mon/Fri). If you have questions, I'm a founder and my email's in my profile.
For full job descriptions, and to hear what it's like working here, go to https://anvil.works/jobs.
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...

We are a small, dedicated team working closely with an established industry partner for rapid, real-world testing and iteration.
We are looking for a Senior 2D/3D Computer Vision Engineer to build the core technology that makes our platform possible. The central challenge is to automatically generate clean, geometrically accurate, and simplified 3D roof models from raw aerial Digital Surface Models (DSM) and RGB data. Your work will be the foundation of our user experience, replacing the opaque and slow manual processes that dominate the solar industry today.
As the owner of this domain, you will ideally:
• Define the Process: Take charge of the entire ML pipeline, from R&D to production. This includes refining the annotation process and enhancing our existing Three.js-based 3D annotation tool to build a high-quality, large-scale dataset.
• Build the Models: Research, develop, and train a suite of models to handle roofprint segmentation, structured prediction of planar roof wireframes from point clouds, and detection/classification of roof obstructions (chimneys, pipes, windows, etc.).
• Ship to Production: Engineer a scalable and robust inference pipeline that can process new properties on demand.
Our stack is Python, PyTorch, FastAPI, Rasterio/GDAL, and JavaScript/Three.js for the annotation tool. We are looking for a pragmatic and experienced engineer who loves tackling complex 3D vision problems. You should be comfortable with both 2D and 3D data (especially point clouds and geospatial imagery) and have a proven track record of delivering end-to-end ML solutions.

Bubblehouse is a fast-growing custom and private loyalty platform. Headquartered in NYC, the entire team is fully remote and spread across US and Europe. We power loyalty programs for large brands, including household names.
We’re again expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.
Tech-wise, we’re running on Golang, and using custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.
Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.
Looking for:
1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.
2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)
3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.
We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.
Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.
(If you have applied before, no need to re-apply, we’ll reach out.)
Roundtable is a research and deployment company building the proof-of-human layer in digital identity. Roundtable seeks to research and build real-world Turing Tests, and to productize these developments in bot detection, fraud prevention, and continuous authentication.
We're hiring a Member of Technical Staff. This is not a typical “Founding Engineer” position. In particular, this role will involve more research than similar positions. You should be prepared to spend around half of your time on research and half on engineering.
The ideal candidate has experience in both. However, we don’t strictly require research experience as long as you have a strong quantitative background and an eagerness to learn. We do require proficiency in both web development (Javascript, Node.js) and Python.
If you're interested shoot an email to matt@roundtable.ai with your resume and a short blurb on why you're interested (note: we are unable to offer visa sponsorship at this time).
