    Now that we’re part of Anaconda, we’re growing the team so that we can do more, faster 🙂 Right now we’re looking for a senior engineer with lots of experience in backend stuff, but an interest in working across the full stack from obscure kernel wrangling, custom Linux container-based virtualization, Django and Flask on the mid-tier, up to TypeScript and React on the front end. There’s even a (tiny) bit of Lua thrown in there. We’re an Extreme Programming team so you’ll be pairing with other team members from day one. All work is remote (bar occasional team meetups), and we can currently hire people based in the UK or in Germany. There’s more detailed information about the role on the official Anaconda jobs board, and you can also apply there – or you can also drop us a line at jobs@pythonanywhere.com.

  • Our Commitment to Providing Free Accounts
    on August 26, 2022 at 12:00 am

    Managing fraud and abuse of free products is a challenge that nearly every SaaS company contends with, but too often the perceived solution is to simply end free accounts. We’ve seen this happen time and again across the open-source ecosystem, most recently from Heroku, and we fear this comes at the detriment of the community. We believe we’ve found a better way to solve this problem and are therefore committed to maintaining free PythonAnywhere accounts for the foreseeable future. Yes, this does cost us money and we do need to handle fraud and abuse, but over the 10 years we’ve been running we’ve found that the benefits to the community and to the service itself outweigh the costs.
