Engineering – 10001 - Communications Platform /

Permanent Full Time Employee /

Hybrid

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.

The Role

We are building a new team from the ground up to work on an ambitious new product in a fast-moving, competitive market. This product will leverage Aircall's core strengths in voice and AI to transform how sales teams operate, helping them work faster, smarter, and more effectively at scale. As one of the first engineers on this team, you'll have significant ownership and influence over the technical direction and product development. We're looking for engineers who are excited to build 0-to-1, thrive in ambiguity, and want to grow with the team, whether that means deepening technical expertise or eventually stepping into technical leadership and management roles as we scale.

Responsibilities at Aircall

Collaborate closely with product managers, designers, and other stakeholders to translate requirements into technical solutions
Have key responsibilities within the design, architecture, and end-to-end delivery of features across the full stack
Build and maintain frontend interfaces with React and backend services with Node.js and TypeScript
Write clean scalable code and test and deploy applications and systems
Revise, update, refactor, and debug code
Participate in code reviews to ensure code quality and share knowledge.

Involvement in product and platform performance optimization and live site monitoring
Participate in an on-call rotation to respond to critical system issues and ensure continuous system reliability
Security is at the forefront of your mind in everything that you do

What We’re Looking For

At least 3 years of professional experience in full-stack development
Experience with AWS services and cloud-based architectures
Deep understanding of software development practices, scalable system architecture, security best practices and cloud-based platforms
Exceptional analytical and problem-solving skills, with the ability to effectively troubleshoot complex issues
Excellent communication and collaboration skills; you thrive working closely with product managers, designers, and cross-functional teams
Comfortable working in a fast-paced, dynamic environment with evolving priorities

Fluency in English is required; Spanish is a plus.

DE&I Statement:

At Aircall, we believe diversity, equity and inclusion – irrespective of origins, identity, background and orientations – are core to our journey.

We pride ourselves on promoting active inclusion within our business to foster a strong sense of belonging for all. We’re working to create a place filled with diverse people who can enrich and learn from one another. We’re committed to ensuring that everyone not only has a seat at the table but is valued and respected at it by providing equal opportunities to develop and thrive.

We are strongly committed to hiring a diverse and multicultural team and we encourage applications from traditionally underrepresented backgrounds.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
