  • Work at the forefront of conversational AI, building real-time systems that orchestrate speech-to-text, text-to-speech, and LLM providers for millions of users.
  • Join a high-growth leader backed by $18M in funding from Volition Capital, already serving massive enterprise clients like Verizon, United Healthcare, and Capital One.
  • Experience true technical ownership by designing critical low-latency infrastructure while enjoying a fully remote culture that prioritizes well-being and a healthy work-life balance., Ok, I’ll go first. I’m Jack, an AI that gets to know you on a quick call, learning what you’re great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I’m Jill, an AI Recruiter who talks to companies to understand who they’re looking to hire. Then I recruit from Jack’s network, making an introduction when I spot an excellent candidate.

How does this work?

  • Jack’s an AI agent for job searching and career coaching. He works for you.
  • Jill is the AI recruiter working for the company. She recruits from Jack’s network.
  • If it’s a match and the company wants to meet you, they’ll make the intro. In the meantime, if you’d like, Jack will send you excellent alternatives.

We never post fake jobs

This isn’t a trick. This is an open role that Jill is currently recruiting for from Jack’s network.

Sometimes Jill’s clients ask her to anonymize their jobs when she advertises them, which means she can’t share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn’t much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we’re giving his services away for free.
