Stellenbeschreibung:

Join to apply for the Senior Backend Engineer (Python) role at Cariqa

Your mission
Cariqa is here to make EV charging work - faster, safer and completely transparent. We’ve built an omnichannel platform that gives Charge Point Operators total control: control pricing, get paid directly, and reach drivers however they want to pay. No markups. No middlemen. Just a transparent platform that helps clean transport scale. We’re not tweaking the old model. We’re replacing it.
We’re backed by leading investors in both climate and fintech - supporting our mission to bring direct, fair, and transparent payments to EV charging. We’re now actively growing our team. If you want to be part of this journey, apply now. And one day, when you plug in your EV and see a fair price at the charge point, you’ll know you helped make that happen.
Your profile
We’re looking for a Senior Backend Engineer (Python) to help us grow and evolve the Cariqa platform. You’ll work on core Python backends built with Django and FastAPI, designing clean APIs, solving challenging data-driven problems, handling mission-critical flows (like payments), and mastering EV-related protocols like OCPI and OICP. You’ll take full ownership of features, from architecture to deployment, and help shape how we build and scale our product.
We’re a small, motivated team where your work will have real impact. If you enjoy building solid and pragmatic systems, working with data, and contributing to a fast-moving, mission-driven product, we’d love to meet you.
Your Responsibilities

Design, implement, and maintain backend services using Python over Django and FastAPI
Orchestrate complex use-cases across different domains (ev-charging, car connectivity, payments, routing, etc.)

Experience working with modern cloud platforms like Google Cloud (preferably) or AWS
Strong understanding of API design and scalable systems
Experience with CI/CD setup and deployment workflows
Familiarity with agile development and Git-based workflows
Comfortable working in a fast-paced, collaborative environment

Knowledge of infrastructure-as-code tools (Terraform, etc.)
Experience with advanced Stripe API (Stripe Connect, etc.)
Experience with observability tools (Sentry, etc.)
Hands-on experience with data analysis and machine learning
