You Will

• Design & implement Linux software (C/C++, Python) for real-time sensing and device control of hardware.
• Integrate hardware & firmware: bring-up boards, write/maintain device drivers, and interface with peripherals (GPIO/UART/I²C/SPI/ADC/DAC).
• Build reliable connectivity: implement and harden device communications using TCP/UDP, HTTP(S)/REST, MQTT, and/or gRPC/Protobuf.
• Harden for production: performance tuning, resource/memory optimization, and fault-tolerant behaviors for large device fleets.
• Ship with discipline: contribute to CI/CD pipelines (build, test, package), containerize services for edge deployment, and support OTA releases.
• Secure the stack: apply secure-by-default practices (TLS, certs/identity, secure boot, signed updates, key handling).
• Test & observe: author unit/integration tests, support HIL testing, add logging/metrics for remote diagnostics and telemetry.
• Collaborate with electrical, mechanical, and cloud/backend teams to deliver features end-to-end on schedule.

You Have

• B.S./M.S. in Computer Engineering, Electrical Engineering, Computer Science, or related.
• 5+ years relevant software development experience with C/C++, Python. Some of this must include Linux experience as well as user space, and ideally kernel, fundamentals.
• Low-level interfacing experience: digital I/O, UART, I²C, SPI; comfort reading schematics and datasheets.
• Networking fundamentals and hands-on protocol work (TCP/IP, sockets; familiarity with HTTP(S), MQTT or similar).
• Strong CS foundations: concurrency/threading, memory management, OS concepts, data structures.
• DevOps fluency for edge: Git workflows; experience with CI systems (e.g., GitHub Actions/GitLab CI/Jenkins) to automate build & test; basic Docker/Podman usage to package edge apps.
• Effective cross-functional communication; clear technical writing.
• Embedded Linux distro/tooling: Yocto/OpenEmbedded or Buildroot; cross-compilers, CMake/GNU Make, toolchains.
• Driver/kernel experience (modules, device trees) and board bring-up.
• Real-time concepts: scheduling/latency, multi-threaded design; RTOS exposure (e.g., FreeRTOS) is a plus.
• Edge orchestration exposure: k3s/microk8s or interaction with Kubernetes-managed services; container registries and image versioning.
• Testing depth: GoogleTest/CTest, fuzz/static analysis (e.g., clang-tidy), HIL or emulator-based CI.
• Security depth: secure boot chains, firmware signing/rollback protection, certificate provisioning/rotation, secrets handling.
• Telemetry/observability: device logging, metrics, and remote diagnostics; familiarity with cloud monitoring/alerting patterns.
• Scripting for automation and data handling (Python/Bash).
