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

• Bachelors or Masters 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
