About

Leedflow is fundamentally changing the way companies find their next client in the most simplest way. We’re transforming how outreach is done and turning the numbers game into the quality game. Imagine, perplexity for B2B data!

We’re early. The foundation is being laid right now, and we’re looking for someone who wants to lay it with us. Titles don’t matter here, ownership, speed, and impact do.

This role is backend-heavy, ideal for someone who thrives in early-stage chaos, balances quality with velocity, and loves shipping fast.

What You'll Do

  • Design, build, and scale backend systems (Python, FastAPI, Django)
  • Work across distributed systems, task queues (Pub/Sub, RabbitMQ, Celery, Temporal), and containerized infrastructure (Docker, Kubernetes)
  • Implement feature flags, observability, and monitoring (Grafana, Prometheus, Sentry)
  • Ship features quickly and iteratively alongside a small, collaborative team
  • Help shape engineering standards, deployment pipelines, and product direction
  • Contribute to (or lead) AI and data features — LLMs, enrichment, scoring — if that’s your thing

What We're Looking For

  • Strong Python skills and experience building scalable APIs
  • Solid understanding of distributed systems, task queues, and observability
  • Comfortable in fast-paced environments with minimal structure
  • Clear communicator with a builder’s mindset
  • Bonus: hands-on experience with AI, ML, or data science — even a side project, LLM experiment, or scrappy data pipeline counts

Why Leedflow

  • Ground floor — shape the product, the team, and the culture
  • Flat hierarchy with full ownership and autonomy
  • Flexible hours and async-friendly work culture
  • A kind, driven, and humble team that genuinely enjoys working together


If you’re passionate about building, shipping, and making a real difference, you’ll fit right in.
