Senior Fullstack Developer

About the position

Atender Group is a specialist in customer experience (CX), and Atender Labs is our innovation engine—dedicated to building next-generation CX technologies that power the group’s services.

We’re looking for a Senior Fullstack Developer to join the Atender Labs team in Málaga. In this role, you’ll be a key contributor to the evolution of our AI-driven customer support platform, helping shape the future of how businesses deliver support at scale.

Responsibilities:

• Design and Develop: You’ll play a key role in building scalable, high-performance web applications using modern front-end and back-end technologies. As we enter an exciting phase of rapid platform expansion, there’s no shortage of greenfield opportunities, expect to ship a lot of code that matters.

• Innovation: Shape the future of our platform by implementing cutting-edge web interfaces and integrating seamlessly with AI providers. Your work will directly enhance user experience, streamline operations, and unlock insights from large-scale data.

About you

• Your Expertise

  • Backend: Proficient in C# and .NET, with a deep understanding of scalable service design.

  • Frontend: Skilled in Vue.js or React.js, with experience using GraphQL to build modern APIs.

  • Cloud: Solid experience deploying and operating applications in Microsoft Azure.

  • Databases: Comfortable working with NoSQL technologies like CosmosDB.

  • Messaging & Event Streaming: Practical knowledge of Azure Service Bus, Kafka, or RabbitMQ.

  • Full Stack Mastery: You’ve delivered end-to-end systems involving everything from UI to backend services, security, networking, and infrastructure automation.

  • AI Engineering: You’ve built and shipped AI-driven features such as RAG (retrieval-augmented generation) systems or conversational agents (chatbots).

  • AI-First Development: You leverage AI tools (e.g., Cursor or similar AI pair programmers) to streamline coding and accelerate delivery. Most of the code you ship is AI-assisted, but still driven by your engineering judgment.
    

• Bonus

  • Experience working with the Twilio Platform, especially Voice SDK and TaskRouter.

  • Hands-on involvement in training and fine-tuning AI models.

  Your Professional Traits:

  • Impact-Oriented: You write code with purpose—always focused on business value, knowing when to perfect and when to pragmatically ship.

  • Collaborative by Nature: You communicate clearly, work well in teams, and foster a positive, solution-focused culture.

Note: At Atender, we hire people — not skills. If this description aligns with your skills today or the path you want to grow into tomorrow, we encourage you to apply—even if you don’t meet every requirement.

• Permanent, Full-Time Employment: Secure a role in a fast-growing company.

• Hybrid Work Model: Enjoy a flexible blend of remote and on-site collaboration.

• Competitive Salary & 24 Vacation Days: We value your expertise and believe in a healthy work-life balance.
