We are looking for a Head of Engineering.

The Mission

X2 builds mental health chatbots, which are proven in many research studies to lower symptoms of anxiety and depression. We believe that combining these AI chatbots with traditional therapy, is the only way to get everyone the care they need - but right now, cannot afford. We just finished our Series A and are scaling to keep up with user growth - spurred by COVID.

The Team

At X2 you get to work with a small but diverse team that includes senior engineers, researchers, and psychologists.

The engineering team at X2 comes from strong technical backgrounds, and share a passion to make a positive impact in the lives of the 29,000,000 people who have paid access to our service. In your role, you will have the opportunity to lead, mentor, and grow this team and have a huge impact in the early stages of a consumer product.

The Tech

Joey Trevino who built the foundation of online bank Chime ($5.8B valuation) retired and is our previous VP Eng. He led a complete rewrite of our codebase, so it has very little technical debt, which allows for adding new features rapidly. We use Python on the back-end and React on the front-end. Our UI mainly consists of text chats on different communication channels and a content creation/training platform for psychologists.

Research is at the core of what we do. We have published 7 research papers, and have 13 more studies in the works. The engineering team’s work directly influences how much symptoms of our users are reduced, of which the results will get published.

The Opportunity

After closing our latest round of funding, we are now scaling up our user base. Millions of messages are exchanged by Tess with people in need, making your impact even bigger.

The engineering team is expected to double before the end of the year. We are looking for a hands-on Head of Engineering to lead the team. In this role, you will help direct architectural decisions, drive to an ambitious roadmap, make tradeoffs in balancing competing constraints. You directly start managing a few engineers, and coding yourself to get familiar with the code. You’ll start to attract and hire new talented engineers to build out your team, and get less involved with coding (if you like).

In this role you will:

  • Work with other stakeholders to set the short and long term roadmap for NLP / NLU and AI at the company
  • Lead your team to impacting high level company goals by facilitating the integration of AI/Automation solutions into the product.
  • Coach and mentor team members from many different backgrounds to grow in both their technical and leadership skills
  • Collaborate with engineers to review designs and advise on high-level and modeling decisions and approaches
  • Grow the team and help shape processes and culture as the company grows

An ideal candidate has:

  • Passion for making a positive impact on the lives of millions of people
  • Experience in web-scale/consumer-facing organizations
  • Broad knowledge of machine learning approaches in general (expertise in NLP, Deep Learning will be valued, not strictly necessary)
  • Ability to work and thrive in a fast-paced, diverse and cross-disciplinary work environment that includes engineers with different backgrounds, psychologists, and UX researchers
  • 2+ years of machine learning (NLP) management experience


  • Unlimited paid time off: as a mental health startup we help keep each other in check to use this policy, and prevent burn-out
  • Choose an annual donation by our Foundation to help a population of your choice: www.x2ai.com/impact
  • Health, dental, and vision insurance
  • Parental leave
  • Remote work
  • 401(k) benefits
