Outbound Capabilities gives Aircall customers a first-class outbound calling experience. 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

Mentor engineers and grow technical leadership across the team, so good decisions don't depend on one person

Own operational excellence: observability, alerting that people trust, runbooks, incident response and root-cause analysis

Partner with the Product Manager and Designer to turn product goals into technical plans, and push back when a technical choice would hurt customers

Coordinate with the teams we depend on: Calls & Routing, Number Management, AI Voice Agents, Integrations and Data Platform

You should have proven experience with

TypeScript and Node.js, production-grade

React, owning components end-to-end, not just familiarity

AWS and cloud architectures (we run on EKS)

GraphQL APIs (AppSync) and event-driven patterns (SQS/SNS workers)

PostgreSQL

Observability with Datadog or similar: designing metrics, monitors and dashboards, not just reading them

Leading the technical work of a team or a multi-quarter initiative: architecture decisions, design reviews, delivery and quality

Mentoring engineers and raising the standard of a team's code, design and operations

Using AI coding assistants or agents (e.g. Claude Code, Cursor, Copilot) daily to design, build, test and debug, with a clear way of checking what they produce

It would be great if you also have

Telephony or dialer experience (SIP, call routing), or CRM integrations (HubSpot, Salesforce)

Twilio calling: Programmable Voice, TwiML, call status webhooks or conferences

Building AI or LLM features in production: prompt and tool design, evaluations, and monitoring quality and cost
