At Aircall, you'll join a company in motion. How we work at Aircall We're customer-obsessed, data-driven, and focused on delivering meaningful outcomes. Users build campaigns from contact lists, the system dials automatically for agents (human or AI Voice Agent), and outcomes flow back to CRMs and analytics. The product is live with hundreds of companies and growing fast.
In this role you own how it's built and how it runs. Set the technical direction of the team: architecture, standards, and the trade-offs between speed and quality. Lead design and delivery of the team's biggest initiatives, from proposal to production, and break them into work the team can ship in small steps. Stay hands-on: write and review production code across the backend and the React frontend. Make AI a core part of how the team builds: use AI coding assistants and agents every day, shape workflows that keep quality high, and help others adopt them well. Bring AI into the product where it helps customers, working with the AI Voice Agents team on campaigns run by AI agents. Raise the bar for the team through code review, design reviews, pairing and coaching. Calls & Routing, Number Management, AI Voice Agents, Integrations and Data Platform.
