About the Role
About Us
Our client develops SaaS platforms that convert vehicle and operational data into actionable insights for fleet operators. The business focuses on solutions that optimise routing, improve compliance, and reduce operating costs through real-time monitoring and analytics. Teams span software engineering, mobile platforms, and data services to support end-to-end fleet management for transport and logistics customers.
Job Description
The Senior Software Engineer C++ will lead development of core backend services that process high-volume telemetry and event streams. The role requires ownership of complex modules, driving performance improvements, and guaranteeing reliability for production systems used across thousands of vehicles. Success will be measured by reduced incident rates, faster feature delivery, and demonstrable improvements in system throughput and latency. The post is a 12-month fixed-term assignment focused on stabilising critical systems while enabling ongoing product roadmap delivery.
Key Responsibilities
- Design and implement performant C++ services that handle telemetry ingestion, processing, and storage.
- Lead code reviews, define standards, and mentor engineers to elevate code quality and maintainability.
- Investigate production incidents, perform root-cause analysis, and deploy durable fixes under time constraints.
- Optimise existing systems for concurrency, memory usage, and low-latency operation.
- Collaborate with product managers and cross-functional teams to translate requirements into technical designs.
- Create and maintain comprehensive unit and integration test suites to safeguard service stability.
- Contribute to capacity planning, performance benchmarks, and release gating for key services.
- Document system design decisions and support operational runbooks for on-call teams.
