Descriptif mission

ROLE SUMMARY Assure end to end quality from edge devices & gateways through secure cloud ingestion & APIs to web/mobile apps. Deliver risk based strategy, automation, and performance/security/resilience programs wired into CI/CD. KEY RESPONSIBILITIES Hybrid testing: Exploratory for usability/edge cases + robust automation for regression and continuous testing. Edge device & data transfer: Validate firmware, secure boot & OTA with rollback, sensor correctness, power/thermal; test store and forward, ordering, de duplication, and integrity across offline/online transitions. Mobile edge gateway: Verify multi WAN (cellular/Wi Fi) behavior, APN/VPN, bandwidth/jitter tolerance; enforce systemd/journald health, watchdogs, cgroups, and remote diagnostics. Cloud & APIs: o Contract & functional tests (OpenAPI/JSON Schema; consumer driven contracts). o API load/performance: steady/spike/soak/chaos; p95/p99 latency & error budgets; idempotency & pagination under load; versioning compatibility. o Multi tenant isolation, authZ/authN (RBAC/ABAC), throttling, blue/green/canary + rollback. Web & Mobile apps: o Automation with Playwright (web) and Appium (mobile); cross browser/device matrices. o Offline/poor network behavior, background sync, deep links, push notifications, WCAG accessibility, and UI under load validations. Connectivity protocols: MQTT (QoS 0/1/2, retained, LWT, session expiry), CoAP, HTTP/HTTPS; impairment injection (loss/jitter/bandwidth caps) and recovery. Performance & resilience (end to end): Reconnect storms, broker/node restarts, partial region loss; verify back pressure, graceful degradation, and recovery within target RTO/RPO. Observability & CI/CD: Embed API/UI/perf suites in pipelines with quality gates; publish dashboards (latency, traffic, errors, saturation), traces, and correlated logs for RCA; track flake rates & trends.

Languages: Python (PyTest/Robot), TypeScript (Playwright), Bash; Appium (Python/JS bindings). Protocols & networking: MQTT, CoAP, HTTP/HTTPS; TLS/mTLS, OAuth2/OIDC/JWT; Wireshark/tcpdump; tc/netem for shaping; mitm for negative testing. Edge/Linux: systemd/journald, logrotate, cgroups, watchdogs, secure update; serial/USB tooling for device bring up. Cloud & containers: Docker/Podman, Kubernetes/OpenShift; API gateways; streams/queues (Kafka/AMQP/MQTT bridges); time series/document/relational/object stores; backup/restore validation. Automation & API tools: PyTest, Robot, Playwright, Appium, Postman/Newman, REST Assured; OpenAPI/JSON Schema; Pact (consumer contracts). Performance & chaos: k6, JMeter, Gatling; MQTT load (mqtt cli/mosquitto/paho); Toxiproxy, tc/netem for impairment; capacity/headroom analysis. Security: OpenSSL/cfssl, cert rotation/pinning, WAF/rate limit tests, secrets management, SAST/DAST awareness. Observability: Prometheus/Grafana, ELK/Loki, OpenTelemetry + Jaeger/Tempo.
