CDI • Paris, France

Cette offre est lié au département Engineering


Aircall is on a mission to revolutionize the business phone industry!
We exist to empower every professional to have richer conversations. We provide an entirely cloud-based voice solution, which seamlessly integrates with popular productivity and helpdesk tools. We have raised more than $220 million since 2015, and our base of 8000+ customers (and growing) is at our forefront.
Behind our product are the amazing teams driving it, split between Paris, New York, Sydney, Madrid, London, Berlin and remote locations. Despite our distance, we all work together to drive our product!
As a Senior Backend Engineer, you will be responsible for the design, development, deployment, and operation of business-critical features of the Aircall product. 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 Typescript / NodeJS as part of a serverless architecture (AWS SAM) we use a number of additional AWS components (Lambda, SQS, SNS, S3, Kinesis, DynamoDB, Cognito to name a few), to deliver highly resilient, scalable services on top of voice and fully integrate with our customers’ business critical tools (CRM, Helpdesk, E-Commerce...).

Your mission @Aircall:

  • Write clean scalable code using Typescript / Node.js, (occasionally Go or Ruby) and test and deploy applications and systems.
  • Have key responsibilities within the requirements analysis, solution design, architecture, and end-to-end delivery of key modules in order to provide business solutions.
  • Revise, update, refactor, and debug code.
  • Be part of an engineering organization delivering high quality, secure, and scalable solutions to Aircall clients.
  • Involvement in product and platform performance optimization and live site monitoring.
  • Mentor team members.

A little more about you:

  • You have at least 8+ years of experience in back-end development , preferably using a typed language (Typescript/Node.js, Java, Scala, C#, Go), with a focus on delivering for security, scalability, availability, and performance.
  • You will have worked extensively with AWS in a production environment, preferably for high volume / high availability services and understand how to design for, deploy on and get the best out of, the environment and services provided by Amazon (significant experience of similar components on GCP or Azure would also be suitable).
  • Security is at the forefront of your mind in everything that you do.
  • You are rigorous with code quality and other engineering best practices (testability, maintainability), and are accustomed to using systems such as Jira, Confluence, GitLab, GitHub, etc.
  • Clean Code, Clean Architecture, Test Driven Development, Behaviour Driven Development and Continuous Integration/Deployment are the way you design, develop and release software.
  • You possess effective and proactive communication skills, and can collaborate with different profiles and roles.
  • You are used to working in Agile teams and look for and implement  continuous improvement, but you also appreciate good process and quality assurance in mitigating risk and improving quality.
  • You can provide technical leadership to manage debt and legacy code with business and technical risk mitigation
  • You favour collaborative practices. You invest your technical and interpersonal experience to mentor juniors and include other engineers in your actions. 
  • You have experience in identifying, debugging and solving complex production issues.
  • Nice to have:
  • Experience of Amazon Aurora on high volume / high throughput applications is a plus.
  • A proven experience with Domain Driven Design would be a significant advantage.
  • Experience with Ruby / Ruby On Rails would be a plus.
A little more about engineering @Aircall:
In the next few years, our technical challenge is to leverage fully decoupled architecture and microservices at scale with reliable, event-driven infrastructure behind the scenes.
- Volume: Store, aggregate and compute 1M+ events/day today, 100M+ by next year
- Live: Analyse and take live decisions based on 1M+ events/day
- Modularity: Make our stack scale and increase squads' productivity by featuring microservices based on event-driven architecture
- Uptime: Keep a 99.99% uptime while dealing with an exponential activity growth
We have built and successfully operated +8 microservices since 2019, and that's just the beginning. There are impacts and changes at all levels: architecture, infrastructure, software, organization, and business.
As we scale our stack, we are scaling our team. We are organized in squads which allows us to combine different experts (tech, product, design, business) around a specific roadmap project. This drastically improved our productivity by focusing on key subjects and making our own decisions. Trust in one another is the key to success, along with commitment and transparency.
We know that success comes from smart work and deserves to be recognized and rewarded
We value people who are bold, ambitious, collaborative and customer-centric. We’re a global community growing together
