Software Engineer Intern - Device Team

## Job Overview This internship offers a chance to build technology that matters — products that directly empower frontline workers. You'll collaborate with engineers in a high-growth environment, working on custom communication devices at the heart of the Relay platform, from application-layer features to deep OS and hardware integration. Interns will gain hands-on experience across the full device stack, from Android application development and OS-level systems programming to embedded firmware and Linux hardware interfaces — contributing to a product that ships to real customers every 6 weeks. Summer interns are expected to work full-time in-office during the summer in our amenity-rich, world-class headquarters in Raleigh, NC. We work with a diverse set of languages, including C, C++, Java, Kotlin, Rust, and Bash/Python. Our devices run Android on custom in-house hardware, and our development environments are Linux-based. Our culture is based on Impact, Team, and Learning. ## What You Will Do You'll work on product development for Relay's custom communication devices — Android-based hardware designed entirely in-house. We own the full stack, from hardware to software, and ship updates to customers approximately every 6 weeks. Depending on your background, you'll contribute across one or more layers: - Android — fix bugs and build new features spanning application development (Kotlin, Java) and OS-level programming, which may touch the Linux Kernel, Java-based frameworks, shell scripts, or C/C++/Rust daemons - Linux OS — work below the Android layer on operating system tasks and hardware interfaces - Embedded systems — develop new embedded products or microcontroller firmware that runs inside or alongside existing Relay devices ## What You Will Bring - Currently enrolled in a Computer Science or related technical field with a GPA of 3.5 or above. - Strong proficiency in C, Java, or Kotlin. Android/AOSP systems programming experience is a plus but not required — if you're a solid developer with a Linux systems background, you can learn Android. - Or experience in embedded systems programming — e.g., NRF or ST-based products running Zephyr, ThreadX, or Linux. - Or experience programming Linux at or below the POSIX API layer, typically in C/C++ (Rust experience is increasingly relevant as AOSP adopts it). - Or solid experience with scripting languages such as Bash, Python, or similar. - Familiarity with IP networking concepts (HTTP, TCP/UDP sockets) is preferred. - Comfort with desktop and server Linux distributions — our development environments and internal tooling are Linux-based. - An analytical, methodical approach to problem-solving. - Strong communication skills and a habit of documenting what you build. - Ability to manage multiple workstreams and self-prioritize. - Exposure to Agile development practices. - Genuine curiosity and drive to learn.
