We are:
Wizeline, a global AI-centric technology solutions provider, develops cutting-edge, AI-powered digital products and platforms. We partner with clients to leverage data and AI, accelerating market entry and driving business transformation. As a global community of innovators, we foster a culture of growth, collaboration, and impact.
We're looking for a hands-on Senior Backend Engineer to join our team as a strong Individual Contributor. This is a deeply technical, execution-focused role — your impact comes from writing clean, production-grade code, solving hard backend problems, and building reliable core services and integrations.
This is a backend-only role. We already have dedicated frontend coverage, so we're not looking for a full-stack generalist — we want someone who goes deep on the backend.
You'll have a voice in architectural decisions and will collaborate closely with the rest of the team, but the heart of this role is craftsmanship and getting solid systems shipped.
With the right people and the right ideas, there’s no limit to what we can achieve
Are you a fit?
Sounds awesome, right? Now, let’s make sure you’re a good fit for the role:
Responsibilities:
- Backend Services & APIs: Design, build, and maintain robust, scalable, and secure backend services and APIs.
- Third-Party Integrations: Build and own integrations between our backend and external/third-party services, with an emphasis on reliability and fault tolerance.
- Security & Identity: Implement and maintain secure web flows, OAuth flows, and On-Behalf-Of (OBO) user permission flows.
- GraphQL & Federation: Contribute to and scale our data graph using GraphQL, including Federation (WunderGraph).
- Cloud Infrastructure: Build and operate cloud-native services on AWS.
Must-have Skills
- Strong Python: Production-grade experience with Python and a modern web framework (FastAPI preferred; Starlette or similar also welcome).
- Web Security & Auth: Strong command of web security and complex web flows, with hands-on experience implementing OAuth and On-Behalf-Of (OBO) user permission flows.
- System Integrations: Solid experience integrating backend systems with complex external services and third-party APIs.
- GraphQL & Federation: Experience with GraphQL, especially distributed/federated graph architectures (WunderGraph a strong plus).
