Senior Developer – gRPC, Kotlin and Connectivity

Multiply & VisFlow Multiply is a technology-driven consultancy operating at the intersection of advanced software engineering, systems design, and data-driven platforms . Together with VisFlow , our product for structured, visual, and traceable technical knowledge, we help organizations build, operate, and evolve complex systems in safety-critical and data-intensive domains. VisFlow is designed to turn complex technical processes, system flows, and operational knowledge into clear, visual, and connected representations . It enables teams to understand, maintain, and scale advanced systems by linking architecture, data, and operational insight across the full lifecycle — from development and deployment to operations and continuous improvement. As Multiply and VisFlow continue to expand within autonomous transport and connectivity platforms , we are looking for several senior developer consultants who want to work close to the core of future mobility solutions. About the Role In this role, you will work on mission-critical connectivity platforms that enable secure, reliable, and real-time communication between autonomous vehicles and cloud or on-premise systems. Connectivity is a foundational capability for autonomous solutions, and your work will directly impact system reliability, safety, and scalability. You will be part of assignments where backend engineering, cloud infrastructure, security, and observability converge. At Multiply, consultants are not isolated resources — you are expected to contribute with technical leadership, architectural thinking, and a strong engineering mindset. Work model: Hybrid What You Will Work With Connectivity platforms forming the backbone of autonomous and distributed systems gRPC-based communication between onboard and offboard components Kotlin-based backend services designed for performance, scalability, and maintainability Secure identity and access management , including certificate-based authentication Telemetry, metrics, and observability , enabling deep operational insight and proactive incident handling OTA and deployment mechanisms supporting efficient lifecycle management of autonomous systems Cloud-native architectures leveraging AWS, containers, and infrastructure as code Your work will often be visualized, documented, and operationalized through VisFlow , ensuring that complex system behavior, data flows, and operational procedures are transparent, traceable, and scalable across teams. Key Responsibilities Design, develop, and evolve secure connectivity platforms between onboard systems and cloud infrastructure Implement identity and access management strategies ensuring unique, trusted identities for connected units Build telemetry pipelines capturing connectivity health, latency, and system metrics Integrate logs and metrics into observability platforms such as Grafana and Databricks Contribute to robust security practices, including encryption, access control, and continuous hardening Develop bring-up, deployment, and operational tooling Implement bandwidth-efficient OTA mechanisms for large-scale deployments Enable real-time communication with high availability and fault tolerance Collaborate in agile, cross-functional teams with a focus on continuous delivery Required Competence Profile Experience: 5+ years of professional experience in backend, platform, or connectivity-focused development Programming & Protocols: Strong proficiency in Kotlin Solid, hands-on experience with gRPC Experience with Kafka is beneficial C++ experience is a plus Cloud & Platform: Strong experience with AWS Familiarity with serverless architectures , Docker , and Kubernetes Infrastructure as Code experience, preferably CloudFormation Databases: Experience with DynamoDB or similar NoSQL solutions Security & Reliability: Strong understanding of encryption, identity management, and secure system design Experience designing systems for high availability and observability Ways of Working: Agile development experience Used to CI/CD, automated testing, and production-grade systems Education Bachelor’s or Master’s degree in Computer Science, Information Technology, or a related technical field Language English (spoken and written) Meriting Experience Exposure to AI-related domains such as: AI Planning Generative AI Knowledge Representation Autonomous Robotics Why Multiply & VisFlow At Multiply, you join a consultancy where deep technical competence, system understanding, and long-term value creation are central. Combined with VisFlow, we offer not only challenging assignments but also a product ecosystem that helps teams see, understand, and improve complex systems over time. You will work close to real-world platforms where reliability, security, and clarity matter — and where your expertise directly shapes how autonomous systems are built, operated, and scaled.
