Senior Software Engineer; Backend

CargoX is a UAE-based autonomous logistics company deploying driverless delivery vehicles across last-mile, middle-mile and long-haul routes. Core Connect is its fleet orchestration platform and the digital glue within its ecosystem of autonomous mobility in logistics. It gives organizations a unified platform to track, manage, and integrate autonomous vehicles, connects with the wider operations ecosystem, and optimizes fleet utilization through data insights and reporting.

We are seeking a Senior Software Engineer (Backend) who prioritizes system reliability and product impact. You will be a key contributor to Core Connect, developing a scalable Hexagonal Backend API service that serves as the primary interface for our commercial ecosystem. We value engineers who operate with a high degree of autonomy, technical pragmatism, and a commitment to operational excellence.

We are specifically looking for candidates who demonstrate ownership, pragmatism, and feel comfortable with navigating ambiguity.

• Core Engineering & Architecture: Design, implement, and optimize scalable Kotlin Spring Boot backend services using a Hexagonal architecture for high-performance fleet orchestration.
• Data & Integration Strategy: Manage complex data layers (Postgres/PostGIS, Timescale DB) and develop a Unified Abstraction Layer to integrate diverse autonomous vehicle APIs for fleet-agnostic control.
• Real-time Systems & Optimization
  :
  Drive the technical roadmap for real-time data engineering, resolving bottlenecks in high-frequency data ingestion (MQTT/Web Sockets) to ensure sub-second latency.
• Security, Scalability & Observability: Enforce standards for platform security and observability, implementing Multi-tenant Architecture (RLS) and Role-Based Access Control (RBAC).
• Cross-Functional Collaboration: Partner closely with Product, Engineering Leadership, and Dev Sec Ops  to build high-quality solutions that drive measurable business outcomes.
• Engineering Culture
  :
  Mentor engineers, lead rigorous code reviews, introduce process improvements, and foster a culture of operational excellence.

• Experience &
  
  Education:
  
  Bachelor’s degree or higher in Computer Science or other relevant fields and 5+ years of professional experience with Java or Kotlin and Spring Boot delivering well-tested, complex systems in a SaaS startup environment
• Architecture & Data Mastery: Deep proficiency in distributed systems, Hexagonal Architecture, and scalable API design. Expertise in SQL (PostgreSQL), geospatial data (GIS/PostGIS), and time-series data (Timescale DB).
• Real-Time & Integrations: Experience architecting low-latency communication (Web Sockets, MQTT) and building abstraction layers for third-party vendor APIs.
• Mindset & Execution: Proven ability to navigate ambiguity, balance architectural purity with commercial objectives (managing technical debt, shipping MVPs), and take full ownership of the code lifecycle and incident management (root-cause analysis and prevention).
• Security & Quality: A consistent focus on software quality and security best practices with hands-on experience in automated testing (unit and integration test suites), SAST, DAST, and setting up platform observability tooling.
• Complementary Expertise:
• Frontend Proficiency: Practical experience building interfaces with React or Next.js and Type Script.
• Infrastructure & Dev Ops: Mastery of cloud environments, specifically AWS and Kubernetes (EKS), along with CI/CD pipelines and Infrastructure as Code (Terraform or Helm)
• Industry
  
  Experience:
  
  Direct background in logistics, robotics, or fleet management systems.
• Communication:
  Fluency in Business English is a must.
