LPWAN wireless Gateway Open-Source Embedded Rust Prototyping

LPWAN wireless Gateway Open-Source Embedded Rust Prototyping

Level of qualifications required : Graduate degree or equivalent

Fonction : Temporary scientific engineer

Context

In the context of a collaboration between Inria and La Poste (the French postal service), a prototype of embedded low‑power gateway will be designed combining microcontroller hardware similar to Nordic Thingy:91, BLE, LTE‑M, GNSS and programmed with an open‑source embedded Rust operating system (Ariel OS). This prototype will be co‑developed with La Poste and tested in the field on La Poste use‑cases.

Assignment

Collaboration : The recruited person will be in connection with the Ariel OS open‑source community & developers, collaborators at La Poste and Inria researchers in the domain of secure IoT and low‑power wireless networking (BLE, LTE‑M, NB‑IOT etc.) as well as the engineers we collaborate with at Campus Cyber.

Responsibilities : The recruited person will be responsible for core embedded OS development, secure low‑power network stack development, and the gateway hardware prototype development and testing in the field. For preliminary information: check out Ariel OS at github.com/ariel-os/ariel-os

Steering/Management : The person recruited will be a hands‑on contact point between Inria, La Poste, and Ariel OS maintainers.

Main activities

Examples of activities :

• Implementation, documentation and CI of embedded Rust components
• Integration of existing Rust crates and/or embedded C libraries as components in the Rust OS

• Social, cultural and sports events and activities
• Theme/Domain : Networks and Telecommunications - System & Networks (BAP E)

Defence Security

This position is likely to be situated in a restricted area (ZRR), as defined in Decree No. relating to the protection of national scientific and technical potential (PPST). Authorisation to enter an area is granted by the director of the unit, following a favourable Ministerial decision, as defined in the decree of 3 July 2012 relating to the PPST. An unfavourable Ministerial decision in respect of a position situated in a ZRR would result in the cancellation of the appointment.

Recruitment Policy

As part of its diversity policy, all Inria positions are accessible to people with disabilities.

About the role

This job is for people who are passionate about prototyping, embedded Rust and low‑power hardware. Obviously having cybersecurity at heart and being an open‑source enthusiast is a plus!
