S35 - Sr Project Engineer Associate Technical Leader - Testing Automation

Key Responsibilities

• 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) behaviour, APN/VPN, bandwidth/jitter tolerance; enforce Systemd/ Journald health, watchdogs, Cgroups, and remote diagnostics.
• Cloud & APIs :Contract & functional tests (Open API/JSON Schema; consumer‑driven contracts).
• API load/performance: steady/spike/soak/chaos; p95/p99 latency & error budgets; idempotency & pagination under load; versioning compatibility. Multi‑tenant isolation, Auth Z/Auth N (RBAC/ABAC), throttling, blue/green/canary + rollback.
• Web & Mobile apps:
• Automation with Playwright (web) and Appium (mobile); cross‑browser/device matrices.
• Offline/poor‑network behaviour, 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.
  
  

• Experience Range: 4-8 years
• Qualification: Bachelor or master’s degree in computer science
• Domain : Experience in aerospace is preferred
• 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.
