Recent discoveries have enabled computers to do a wide range of things that previously only humans could do. Making sure this technology is not locked away but open and available for everyone to use is our mission.

Why join us?

  • Spell has recently received a Series A fundraising round bumping our funding up to 15 million, which is allowing us to focus on growing our product and engineering team. Spell is the rare combination of being a startup, in a burgeoning industry, with experienced leadership. Our leadership has ample experience in scaling a team, a product, building infrastructure, and studying Machine Learning/AI. Working at Spell allows engineers the opportunity to work in an exciting startup environment without the usual concern of it failing due to inexperience and immaturity.

  • Our CEO, Serkan, has had leadership experience founding the Facebook NY office, and scaling it from 0 to 1000 engineers, while heading up culture and recruiting initiatives. Serkan also cofounded the Facebook Artificial Intelligence Research Lab along with Yann Lecun. The rest of our team has worked at companies such as Facebook, Google, Microsoft, eBay, Clarifai, Zocdoc, Betterment, and Square.

  • We are focused on bringing the right combination of talent, diversity, and camaraderie to the early stages of Spell as we scale. You will have ownership of a significant portion of our product, and will directly influence our culture while working in a new and exciting field.

Engineering at Spell

Engineering team and processes

We have a relatively small engineering team of 8, and thus have no unnecessary processes. Everything we do is very diligent and intentional, and we try to automate everything: It's allowed our 8-person team to appear like one with 30 people. Most of our team is full-stack, which means they work close to baremetal configuring or deploying virtual machines on-prem, but also work closer to our users implement features inside our API and front-end written in golang/React.

Technical Challenges

We have built infrastructure that's made training and deploying machine learning algorithms inside all public clouds and even private on-prem clouds extremely easy. What usually takes entire devops teams years to achieve, can be achieved within minutes with just a few clicks from our customers.

Our customers run experiments massively in parallel, however, they need to access their datasets and view their metrics for how well their models, and that all needs to be performant. This has required us to scale using multi-level caching and redundancy for streaming information across different public clouds and regions of public clouds.

Projects you might work on
  • Create the user interfaces for generating and managing multiple AI experiments in parallel, while showing streaming metrics from these experiments in beautiful dashboards

  • Build a FUSE filesystem that will act as a multiple layered cache for large datasets that are hosted in object stores
