Role

Who you are

You have at least 4 years of experience building products and systems in production
You are an amazing communicator
You feel comfortable managing your time and deciding among competing priorities
You are passionate about the future of work
You enjoy learning and teaching
You have some mobile experience
You are comfortable working with backend and frontend technologies, but have a deeper background and interest on the backend side
You care about and want to contribute to our mission of helping people do meaningful work
We're somewhat flexible on the number of years of previous experience for this role. We highly favor talent and interest
Some candidates may see this list and feel discouraged because they don’t match all the items. Please apply anyway: there’s a good chance you’re more wonderful than you think you are
B12 is a safe place for human beings. We particularly encourage you to apply if you identify as a woman, are a person of color or other underrepresented minority, or are a member of the LGBTQIA community

What the job involves

B12's engineering team views software as a craft, but improving the world as the reason to practice it
Our engineers are responsible for prioritizing, conceptualizing, co-designing, building, testing, and engaging users for any concept we are building out
We’re generalists in encouraging each other to experience the full stack, but we’re also aware of each other’s preferences in the stack
For this role in particular, we’re searching for a full-stack engineer who brings strong backend skills (and an interest in using them) to the product
We mentor and teach where we can, both inside and outside of the company
We value sharing our work with the outside world
Our team has published papers on forming expert flash teams and machine-mediated worker hierarchies
We’ve baked our research into Orchestra, the system that coordinates our expert and machine teams, and released Orchestra into open source to contribute our software back to the community
We hope our engineers have more longevity than any one tool we use, but here is a sampling of our current thoughts about technology:
We live on Python/Django and TypeScript/React
We store blobs in Amazon’s S3, munch on them in Amazon’s EC2, develop in Docker, and deploy containers to Amazon’s Elastic Beanstalk
We believe PostgreSQL should be the first system you consider when thinking about persisting structured data
We clean and centralize data in Amazon’s Redshift, and are able to answer almost any question in SQL
We leverage AI in our product and our internal tooling, and faced with a landscape in constant flux, try to pick the right model or agent on a task-by-task basis
We have near-full test coverage on the backend, and are making progress on our frontend and integration tests
We set up continuous integration and deployment because, while this model comes with its own pains, we’ve disliked being on fixed release schedules on previous projects
We like to move fast and support point-in-time recovery :)

Application process

Please provide: A pointer to your CV, resume, LinkedIn profile, or any other summary of your career so far
If you have a profile on websites like GitHub or other repositories of open source software, you can provide that as well. If you don’t have one, it’s still very possible for us to get along just fine!
In addition to the traditional application details, we also ask that you complete a small technical challenge below. Two notes:
By virtue of submitting your application via a public platform like GitHub, it's possible for people to search for projects with "B12" in the repository name/description/contents and see that you have applied. You can obfuscate these details for your privacy, but contact us if you could benefit from a slightly different process to further protect your privacy
We’ve never tried a “write code to apply to B12” exercise before, and introduced it because of a recent deluge of AI-generated/AI-mediated applications that has made reviewing inbound applications infeasible for us. We hope that introducing this exercise results in a smaller number of qualified candidates without serving as too much of an impediment. You are welcome to use AI assistance on this exercise (we did!). We imagine we’ll iterate on this experiment, and very much welcome your feedback on your experience

Our take

Following the recent wave of digital transformation, it’s more important than ever for businesses to have a strong online presence. For the growing number of SMBs and solo entrepreneurs, however, creating a high-quality website can prove difficult and costly. So a market has opened up for on-demand web design and site building.

B12 is one of the companies answering this call, enabling users to launch personally designed SEO-optimized websites within 30 days using its AI-assisted team of designers and copywriters. The company also helps site owners to manage email marketing and automation, online payments and invoicing.

In this way, B12 offers easy access to the benefits of a good website without the headache of designing and optimizing it oneself. And its growth and high number of signups showcase the need for what the company is offering. With this strong product foundation and plans to build it out further, B12 is making strong headway in this market niche.
