Jr. Embedded Developer
Englewood, CO - onsite
1. Embedded C Programming, Linux, Operating System (5+ years)
2.
WiFi standards and Networking Domain Expertise (5+ years), basic understanding of 5G/LTE technology (high level)
3. Strong debugging and problem solving skills (5+ years)
Prior experience working with networking devices such as wifi routers, cable modems, CMTS etc. will be beneficial.
Hands on experience working with Opensync, OpenWRT, RDK-B etc. will be an advantage.
WiFi Integration
Develop and maintain WiFi radio configuration across Qualcomm, Broadcom, and Atheros chipsets for 2.4GHz, 5GHz, and 6GHz bands
Implement and debug WiFi features including band steering, client steering, channel selection (Client/non-Client), BSS Coloring, OFDMA, MU-MIMO, TWT, and MLO (WiFi 7)
Work with hostapd/wpa_supplicant configuration, CFG80211/mac80211/nl80211 driver interfaces
Develop and maintain OpenSync WiFi managers for cloud-managed radio configuration, client monitoring, and statistics reporting
Debug WiFi driver crashes, firmware asserts, performance regressions, and interoperability issues across client devices
Implement mesh/extender backhaul configuration and optimization
Develop and tune RvR (Rate vs Range) and throughput KPIs across firmware builds
Support channel switching, ECSA, radar detection (Client), and regulatory compliance across multiple country codes
Cellular Backup (Phone-as-Backhaul)
Implement phone-as-backhaul connectivity - enabling the router to use the customer's mobile device as a backup WAN path
Develop the router-side failover client that communicates with the companion mobile app (MSA) to initiate and terminate backup sessions
Implement WAN outage detection and internet reachability healthcheck framework
Develop route arbitration and traffic steering logic between primary WAN and phone-based cellular backup
Manage concurrent WiFi AP + STA operation - serving home clients on AP while connected to phone hotspot as upstream STA
Handle USB tethering detection and network interface management (RNDIS/CDC-NCM/CDC-ECM)
Implement graceful failback logic when primary WAN recovers
Develop LED state machine logic for multi-WAN connectivity status indication
Implement QoS and bandwidth management during cellular backup mode (customer's data plan awareness)
Platform & Common
Design, develop, and debug embedded C software for Linux-based residential gateway platforms (ARM/MIPS SoC)
Develop and maintain OpenSync managers - event-driven daemons that interact with OVSDB for cloud-managed configuration and state reporting
Implement secure communication channels using TLS with mutual authentication (mTLS) between router and cloud/mobile app
Debug kernel-level issues including network driver crashes, kernel panics, and memory leaks
Develop init scripts, UCI configuration handlers, and persistent storage management for OpenWrt
Analyze and resolve field issues using device logs, crash dumps, logpull analysis, and remote diagnostics
Write unit tests and participate in code reviews via GitLab merge requests
* Collaborate with hardware teams, QA, cloud platform engineers, mobile app teams, and service provider partners
