13001 - EngineeringPermanent Full Time Employee
Aircall is a unicorn, AI-powered customer communications platform used by 22,000+ companies worldwide to drive revenue, resolve issues faster, and scale customer-facing teams. We’re redefining customer communications by bringing voice, SMS, WhatsApp, and AI together into one seamless workspace.
 
Our momentum comes from a simple idea: help teams work smarter, not harder. Aircall’s AI Voice Agent automates routine calls, AI Assist streamlines post-call work, and AI Assist Pro delivers real-time guidance so people can do their best work. The result is higher revenue, faster resolutions, and teams that scale with confidence.
 
Aircall is headquartered in Paris, our European HQ, with a strong North American presence anchored in Seattle, our North American HQ, and teams across Madrid, London, Berlin, San Francisco, New York City, Sydney, and Mexico City. We’ve built a product customers love and a business that’s scaling quickly, backed by world-class investors and driven by rapid AI innovation across multiple product lines.
At Aircall, you’ll join a company in motion. We’re ambitious, product-driven, and execution-focused, with visible impact, fast decisions, and real growth.
 
How we work at Aircall: We’re customer-obsessed, data-driven, and focused on delivering meaningful outcomes. We value ownership, continuous learning, and thoughtful speed. If you thrive in a collaborative, fast-moving environment where trust and impact matter, you’ll feel at home here.

Aircall has acquired Piper AI, and together we're building the future of autonomous sales.

Aircall powers the customer conversations that drive revenue for 23,000+ businesses—but deals don't close on a single conversation. They move, or stall, across calls, emails, video, and more, most of which is invisible at the pipeline level. Piper changes that. Every interaction, wherever it happens, automatically updates the CRM, scores the deal, and triggers the next step. No manual entry. No blind spots. No deals slipping through.

To build on this foundation, Aircall is launching a dedicated New Product Unit bringing together Aircall and Piper AI to accelerate the vision: an AI Orchestration Layer that captures and understands every customer interaction—calls, video, email, WhatsApp—and autonomously executes the workflows that follow: CRM updates, follow-ups, task creation, and coaching insights. The long-term goal is a self-improving, agentic Sales OS, where specialized AI agents collaborate, coordinate, and continuously optimize the entire revenue process.

The Role

We’re looking for a strong Senior Python Engineer who’s eager to go beyond traditional backend development.

This role is for someone ambitious—someone who takes pride in building things well, but knows how to move fast in a startup environment. You strike the right balance between clean architecture and pragmatism, between perfection and progress.

You’re energized by hard technical problems—distributed systems, AI orchestration, architectural trade-offs, performance, and scalability. You can go deep when needed, but you’re equally focused on shipping, learning, and iterating quickly.

You’re curious by nature, committed to continuous improvement, and excited to bring the most effective modern approaches—whether agentic patterns or AI-augmented development workflows—into real-world production.

This isn’t just another engineering role. It’s an opportunity to help build the intelligence layer behind a next-generation autonomous Sales OS.
