Job Specifications

Aircall is a place where voices are valued.

Backed by over $220 million of investment since 2015, we create technology that fuels accessible, transparent and collaborative communication to empower our base of 20,000+ customers (and growing) to make authentic, human connections.

Conversation is a cornerstone of our culture. Wherever our people find themselves in the Aircall world – Paris, New York, San Francisco, Sydney, Madrid, London, Berlin, Seattle, Mexico City or at home – everyone has a voice that is valued.

Whatever your background, wherever you’re from – we want you to join the conversation. Let’s talk.

As a Senior BE & AI Engineer , you will be responsible for the design, development, deployment, and operation of business-critical AI features that add customer value on top of Voice. Previous experience implementing AI features is a must. Best practices, evangelization, and mentoring in your team and across the whole of Engineering will be part of your day to day job.

Quality, excellence, and agility drive our delivery processes and you will help us level these up. Using a variety of back-end stacks, appropriate for each requirement, but always hosted on AWS, we build added value and resilient services on top of voice and fully integrate with our customers’ business critical tools (CRM, Helpdesk, E-Commerce, …).

Your mission @ Aircall:

Participate in requirements analysis to help with providing the right technical and business solutions for our customers
Propose innovative solutions based on AI landscape trends
Have key responsibilities within the design, architecture, and end-to-end delivery of AI key modules
Write clean scalable code and test and deploy applications and systems
Revise, update, refactor, and debug code
Be part of an engineering organization delivering high quality, secure, voice solutions to Aircall clients
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
Mentor team members

A little about you:

AI experience is a must for this position: Knowledge about LLMs (GPT, Mistral, Llama, Claude, etc…) and experience developing with them (usage, prompting, etc), AI frameworks (Langchain, LlamaIndex, Auto Gen, etc), AI architectures (RAG, reranking, etc)
You have at least 5+ years of experience in back-end development in a large scale, preferably typed language (Typescript/ Node.js , Java, Scala), with experience in Javascript, Ruby, or Python, with a focus on delivering for security, scalability, availability, and performance
Nice to have: Ideally you will have worked with AWS in a production environment and understand how to design for, deploy on and get the best out of, the environment and services provided by Amazon
Security is at the forefront of your mind in everything that you do

Aircall is constantly moving forward. We’re building new roads to complete our journey, and we’re taking people with us who have the same builder mentality.

Let’s grow together: Aircall is a place for those who dare to be bold and seek responsibility, excellence, and the opportunity to push themselves to new heights.
