    Job Technologies

    Your role in the team

    • You are not just a coder; you are a Solution Architect and Prototyper.
    • In this role, you will bridge the gap between abstract requirements and shipping software.
    • You will use your "End-to-End" expertise to design scalable APIs, manage databases, and build intuitive frontends using Next.js.
    • Crucially, you will be a pioneer in using GenAI tools for rapid prototyping.
    • Instead of spending weeks on a proof-of-concept, you will use AI to transform abstract ideas into working prototypes quickly, validating assumptions before we commit to the deep engineering work.
    • End-to-End Delivery: Drive the full development cycle.
    • You will design scalable backend services (Node.js/Go), optimize database schemas (SQL/NoSQL), and build responsive frontends (React/Next.js).
    • Architecture & Design: You don't just follow instructions; you design the solution.
    • You will decide on the right API strategy (REST/GraphQL), the right data model, and the right cloud infrastructure.
    • Rapid Prototyping with AI: Transform abstract feature ideas into tangible prototypes using GenAI tooling.
    • You use AI to accelerate the "discovery" phase, helping the product team visualize solutions faster.
    • Quality Engineering: Design and execute comprehensive test strategies.
    • You believe in TDD and ensure that unit, integration, and end-to-end tests are part of the definition of done.
    • Documentation & Knowledge: Ensure that our systems are not "black boxes."
    • You maintain comprehensive technical documentation and document working patterns so the team scales with you.
    • Mentorship: Actively participate in code reviews.
    • You look beyond syntax errors to spot architectural misalignments and help colleagues improve their code quality and performance.

    Our expectations of you

    Qualifications

    • A mastery of Distributed Systems: You understand the fallacies of distributed computing, eventual consistency, and how to build fault-tolerant architectures.
    • You don't just write code; you architect solutions that generate code.
    • You aren't just an app developer; you know how your code lives in the cluster.
    • Deep knowledge of RESTful and RPC-based APIs, and you treat API design as a first-class citizen.
    • Vertrautheit mit asynchronen Nachrichtensystemen (RabbitMQ, Kafka, PubSub) und Wissen, wann sie gegenüber synchronen Aufrufen eingesetzt werden sollten.
    • You are a clear communicator who can explain complex abstract concepts to both technical and non-technical stakeholders.

    Experience

    • 5+ years of full-time Backend Development experience, with a strong preference for Golang and a deep understanding of OOP/SOLID principles.
    • A "Force-Multiplier" Mindset: You have experience (or a strong interest) in using AI tools to enhance software quality and velocity.
    • Practical experience with Docker and Kubernetes.
    • Experience with cloud platforms (GCP preferred) and modern database strategies (relational vs. NoSQL).
