ABOUT THE ROLE
We are looking for senior and staff-level fullstack engineers eager to join the team building our leading Magic AI features.
At Hex we're deeply focused on building powerful, integrated AI features that augment and accelerate analytics workflows. The possibilities here are incredible, and we're uniquely positioned to re-invent the way people think about understanding data.
In this role, you’ll take the lead on building AI-powered features into Hex, partnering closely with our Research team on context and model prompting, and the rest of our product engineering teams on integrating into the platform. The fruits of your work will fundamentally change the way that many thousands of people work with data, and give you a front-row seat to the most exciting technological shift in our lifetimes. As part of our Agent Platform team, you’ll own the scalable agent infrastructure powering today’s most powerful data agents, as well as the cutting-edge experimentation tooling that allows the rest of the team to rapidly deliver new AI features in the product.
WE'D LOVE TO HEAR FROM YOU IF YOU HAVE:
- At least 4+ years of software engineering experience.
- Proficiency with React and Typescript in addition to knowledge around architecture and systems design.
- Experience leading and executing on major product initiatives.
- Excitement for getting your hands dirty and diving deep into how the browser works to develop high-quality and performant user experiences.
- An aptitude for how web infrastructure works to develop high-quality internal developer and external user experiences.
- An instinct for strategic thinking and aligning with business and product goals while keeping a healthy balance of velocity and engineering excellence.
- Interest in the data space, and a love of shipping great products and building tools that empower end users to do more.
- Experience maintaining a high quality bar for design, correctness, and testing.
- An ability to lead product initiatives while collaborating and mentoring fellow engineers.
- Curiosity and an interest in diving into the bigger picture of building a company, including go-to-market, customer development, people, and marketing.
This role will be hybrid (1-2 days per week) based out of our San Francisco, California headquarters or NYC office.
OUR STACK
Our product is a web-based notebook and app authoring platform. Our frontend is built with Typescript and React, using a combination of Apollo GraphQL and Redux for managing application state and data. On the backend, we also use Typescript to power an Express/Apollo GraphQL server that interacts with Postgres, Redis, and Kubernetes to manage our database and Python kernels. Our backend is tightly integrated with our infrastructure and CI/CD, where we use a combination of Terraform, Helm, and AWS to deploy and maintain our stack.
The salary range for this role is: $198,750 - $295,000
In addition to our unique culture, Hex proudly offers a competitive total rewards package, including but not limited to, market-benched salary & equity, comprehensive health benefits, and flexible paid time off.
