Job Description

Our client built an AI-powered sales platform helps B2B companies generate more opportunities thanks to our advanced lead generation engine, hyper-personalized sequencing, omnichannel outreach, and AI-powered smart actions. We are backed by Y Combinator, and we are powering the sales teams at some of the fastest-growing companies in the world like Deel, Moveworks, H1 and Vanta.
Our main goal is to build a sales platform that helps companies grow. Our product requires us to solve a myriad of difficult engineering problems very diverse in nature: from working on NLP models that can extract information from a thread of emails, to scaling an elasticsearch cluster holding terabytes of data.

We are deeply aware of the importance of our tool to our customers and look for people that share that vision.

Among other things, our stack includes:

Ruby on Rails, React, PostgresQL, Elasticsearch, Redis

We don't require you to have experience in our stack to apply.

However, it's important to note that while this position primarily focuses on people and process management, there is a significant technical aspect we expect from candidates. The ideal candidate should possess the ability to work hands-on with the codebase when necessary, providing technical guidance, troubleshooting complex issues, and ensuring the overall quality and efficiency of our engineering efforts.

This role offers the unique opportunity to lead and shape greenfield projects from inception, guiding a team as you build pioneering products leveraging Large Language Models and cutting-edge AI technologies that don't yet exist in the market, giving you unparalleled creative freedom and impact.

Main Responsibilities:

  • Work directly with the co-founders
  • Have lots of autonomy and impact
  • Provide leadership and mentorship to other engineers on the team
  • Plan engineering sprints
  • Recruit a robust team of engineers that are among the best in the industry, from outreach to closing
  • Empower the engineering team to achieve a high level of technical productivity and quality
  • Manage an excellent team of engineers, helping to develop their careers with stretch projects and excellent feedback
  • Contribute to engineering-wide initiatives as part of the engineering management team
