Cloud Developer - Collision Avoidance System

This role will design and deliver cloud and edge-to-cloud capabilities that enable safe, reliable, and observable operation of a Collision Avoidance System across heavy mobile equipment. You'll build and operate telemetry ingestion, device messaging, APIs, data stores, and dashboards, partnering closely with embedded, systems/safety, and product teams. A key focus is modernising and hardening the road-side-to-cloud path over LTE/4G (MQTT) while maintaining backwards compatibility as hardware evolves.

Key Outcomes:

• Reliable, low-latency ingestion from road-side components over LTE/4G with MQTT QoS tuned for safety and bandwidth efficiency.
• Production-grade APIs and data models used by analytics, simulation, incident review, and safety case stakeholders.
• End-to-end observability: metrics, traces, structured logs, fleet health dashboards, and alerting aligned to clear SLOs.
• Secure device identity, provisioning, and lifecycle management with audit trails and least-privilege access (IEC 62443 aligned).
• Data quality and retention that supports safety analysis, regression studies, and regulatory evidence.

Key Responsibilities:

• Build cloud-native services for telemetry ingestion, device messaging, and command pathways using MQTT plus REST/gRPC where appropriate.
• Engineer streaming and batch pipelines for logs, metrics, and events to support diagnostics, fleet analytics, and product insights.
• Define and maintain message schemas and contracts across onboard, road-side, and cloud boundaries, ensuring backward compatibility.
• Design scalable storage layers (time-series, object, relational) with partitioning, indexing, and lifecycle policies for cost-efficient retention.
• Establish and operate observability standards including centralised logging, distributed tracing, SLOs/SLIs, and on-call readiness.
• Implement secure device onboarding, certificate/key rotation, secrets management, and RBAC for internal services and dashboards.
• Work with embedded and systems/safety engineers to translate safety requirements into cloud-side validations and fail-safe behaviours.
• Produce strong technical documentation: interface specs, sequence diagrams, runbooks, data dictionaries, and operational playbooks.
• Improve CI/CD, infrastructure-as-code, and automated testing (contract, integration, performance, chaos) to support safe releases.
