Deine Aufgaben
Build and scale the customer service platform that handles millions of passenger conversations across markets - from AI-powered chatbots and voice agents to help center and knowledge base tools. We run a polyglot stack (Python, TypeScript, Terraform) on AWS, integrating Twilio, Cognigy, Kafka and AWS Bedrock. We ship continuously and own our services end-to-end, from Terraform to production.
- Design, build and maintain Python (FastAPI) backend services and TypeScript/React frontends across the CS platform
- Take greenfield products from concept to production - make architectural calls, prototype, validate, and iterate under uncertainty
- Develop and extend Twilio Functions (JavaScript) for voice/IVR and webchat flows
- Manage the infrastructure as code with Terraform (HCL) on AWS - you build it & deploy it
- Integrate third-party and AI platforms: AWS Bedrock, Twilio, Cognigy, LiteLLM, Kafka
- Apply AI to your engineering practice - use and help improve our internal AI tooling to ship faster and raise quality
- Instrument and monitor services (Datadog, event forwarding, alerting) and respond to production issues
Dein Profil

- Hands-on with AWS and infrastructure-as-code (Terraform)

- Strong ability to navigate vague or shifting requirements - a bias for action, comfort making decisions with incomplete information, and the judgment to avoid analysis-paralysis
- Pragmatic, ships iteratively, communicates clearly
- Curious about and comfortable working with AI tooling in day-to-day development
- Experience building products from scratch (0→1) in a fast-moving team
- Conversational AI / chatbot / IVR experience (Twilio, Cognigy, DialogFlow)
