The posting

About the Role Our client is a high-growth, venture-backed startup (recently closed a $10M+ Series A) building the industry-leading agentic AI platform for real estate operations. Their technology autonomously handles over 75% of client support interactions across email, SMS, WhatsApp, and voice.

We are seeking a heavy-hitting Senior to Principal level Software Engineer (7–12 years of experience) to join a lean "rockstar" engineering team. You will help scale the engineering organization from 6 to 12+ members while maintaining a rapid shipping velocity. This is a backend-leaning, full-stack role for an elite Individual Contributor who wants to build at the frontier of AI.

What You’ll Do

  • Architect & Ship: Lead the development of major features for omnichannel AI agents, making critical decisions on infrastructure and system design.
  • Build with AI: Integrate AI coding tools (Cursor, Claude Code) into your daily workflow to accelerate development.
  • Collaborate: Work directly with the CTO and founders to shape technical strategy and product direction in fast-paced weekly cycles.
  • Scale Systems: Design and deploy scalable, high-impact systems on AWS that support 6–7x year-over-year revenue growth.
  • Operate Full-Stack: Move fluidly across the stack as needed—shifting priorities weekly based on business impact rather than staying in a technical silo.

Who You Are

  • The Veteran IC: 7–12 years of production experience at top-tier Big Tech firms or recognizable high-growth startups. You are a builder, not a manager.
  • Python Expert: Deep production experience with Python as a primary backend language. Familiarity with TypeScript and React is a strong plus.
  • AI-Native Developer: You are highly proficient with modern AI coding tools and believe in the "10x engineer" potential of agentic workflows.
  • Product-Minded: You understand the business context of your code and care about the "why" behind the product.
  • Education & Background: Strong academic background (Top CS programs) or previous experience as a founder/CTO is highly preferred.

Why Join?

  • Work with a team of ex-Meta, Google, and Microsoft engineers.
  • Massive equity upside in a company that has proven product-market fit and explosive revenue growth.
  • High autonomy in a "no-ego" environment where the best ideas win.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
