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.
