Responsibilities

Design, develop, and maintain the core backend systems supporting our data and simulation applications. Ensure robust, scalable, and secure server-side functionality to handle massive volumes of vehicle telemetry, analysis compute, and relational database management.
Build and manage high-performance APIs (REST, GraphQL, or gRPC) to enable seamless data exchange between internal microservices, external partner systems, and our front-end interfaces.
Implement efficient data storage, retrieval mechanisms, and ETL (Extract, Transform, Load) pipelines to support complex data processing and analytics. Ensure data integrity, security, and compliance with industry standards.
Optimize server performance for low latency and high throughput. Identify and resolve systemic bottlenecks, optimize database queries, and ensure cloud infrastructure scales efficiently under load.
Architect and manage scalable cloud deployments utilizing 'infrastructure as code' (IaC) techniques to maintain reliable and repeatable environments.
Develop and execute comprehensive testing plans (unit, integration, and load testing) to ensure backend reliability and resilience. Troubleshoot and resolve complex system issues and bugs promptly.
Work closely with cross-functional teams—including embedded systems engineers, data scientists, and front-end developers—to deliver cohesive software solutions and practice continuous improvement.
Create and maintain detailed, up-to-date documentation of system architecture, data models, and APIs to ensure clarity and long-term maintainability.
