You've worked with modem control interface layers, such as Qualcomm's TelSDK or QMI, or the Android RIL. * You know how to integrate cellular data into an operating system, through routing, firewalls, tethering, VPNs, and handoffs between WiFi and cellular. * You know how to triage and debug end-to-end issues in a team, and can perform and analyze packetcaptures. You enjoy debugging difficult latency and connection issues that span framework, modem control, radio, kernel, and carrier. * Most of our code is written in C, C++, and Java, so we expect you know at least one of these languages well. * BS/MS/PhD in computer science or electrical engineering (or equivalent experience) * 5+ years software development experience * Most importantly, you have a deep drive to make cellular work perfectly, on any carrier, modem, and in any signal conditions. Preferred qualifications: * Experience collaborating with radio and operating system vendors to debug issues * Experience with IMS-adjacent system integration (VoLTE/VoWiFi behaviors, emergency calling flows, QoS policy plumbing) focusing on OS services andreliability rather than deep protocol implementation. * Familiarity with 4G/5G device behavior from an OS perspective (network selection policies, roaming behavior, dual-SIM/DSDS state management, recovery strategies). * Experience with eSIM/eUICC userland flows (activation/provisioning UX, profile management, secure storage, lifecycle and error recovery) and carrier-driven edge cases. * Strong automation background for cellular reliability: lab harnesses, simulated networks, test plans aligned with certification suites, and telemetry-driven regression detection. * Working knowledge of modem control-plane interfaces end-to-end: high-level vendor control APIs/SDK patterns and their underlying transports (e.g., QMI/MBIM/AT-style concepts), plus coordination with power/thermal and connectivity policy. * The ability to collaborate with hardware engineers to debug antenna, power and operating system issues, 4G (4th Generation) Wireless, Analysis Skills, Android, Antenna, Application Programming Interface (API), Automation, C Programming Language, C++ Programming Language, Cloud Applications, Computer Engineering, Computer Science, Debugging Skills, Electrical Engineering, Equal Employment Opportunity (EEO), Error Recovery, Firewalls, Hardware Debugging, Hardware Design, IP Multimedia System (IMS), Java, Kernel Programming, Linux Operating System, Maintenance - Plumbing, Management Strategy, Modems, Network Simulation, Network Systems, Network Testing, Operating Systems, Process Improvement, Product Development, QoS (Quality of Service), Software Design, Software Development, Software Engineering, State Laws and Regulations, System Integration (SI), Team Player, Technical Recruiting, Telemetry, Test Plan/Schedule, User Interface/Experience (UI/UX), VPN (Virtual Private Network), Wi-Fi, Wireless Communications ## Description We think wireless communication can be perfectly reliable - no matter where our cars go. We're looking for cellular experts who agree. ## Related Videos - [Using WebAssembly to run, extend, and secure your application](https://www.wearedevelopers.com/videos/652-using-webassembly-to-run-extend-and-secure-your-application) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Unlocking the potential of Digital & IT at Vodafone](https://www.wearedevelopers.com/videos/602-unlocking-the-potential-of-digital-it-at-vodafone) - [On developing smartphones on wheels](https://www.wearedevelopers.com/videos/258-on-developing-smartphones-on-wheels) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [7 Important Tips That Every Software Developer Should Know](https://www.wearedevelopers.com/magazine/101-7-important-tips-that-every-software-developer-should-know) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
