RWX | Software Engineer | REMOTE (US) | Full-time | https://rwx.com

$175K – $250K + equity

We're a CI/CD platform with an entirely differentiated execution model. Rather than parallelizing jobs on VMs, we provide a serverless interface using a graph of tasks. We then have automatic, content-based caching, which eliminates the large amount of redundant executions that CI platforms have today. You can test changes from a local CLI so that you don't have to commit and push to run. We've made substantial improvements to every aspect of the developer experience.

We're looking for backend-focused engineers who excel at building developer tools. Our engineers are effectively product managers as well and work highly autonomously.

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

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.

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.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

We're a CI/CD platform with an entirely differentiated execution model. Rather than parallelizing jobs on VMs, we provide a serverless interface using a graph of tasks. We then have automatic, content-based caching, which eliminates the large amount of redundant executions that CI platforms have today. You can test changes from a local CLI so that you don't have to commit and push to run. We've made substantial improvements to every aspect of the developer experience.

We're looking for backend-focused engineers who excel at building developer tools. Our engineers are effectively product managers as well and work highly autonomously.

TigerData (FKA Timescale)
[ Global | 100% Remote | Multiple Roles: Eng, Product + more ]

We began in 2017 as Timescale, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.

Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads.
To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.

This is not a reinvention: it’s a reflection of how we already serve our customers today.
