Join our team and help shape the future of connectivity indoors and outdoors. Together, let's push the boundaries of technology and advance sustainable networks worldwide.

How You'll Help Us Connect the World

As a MAPLE Accelerators Systems Engineer, you will provide hands-on technical expertise supporting development, integration, and troubleshooting of MAPLE hardware accelerators and embedded firmware on Freescale B4860 platforms. You will work closely with DSP, platform software, and system engineering teams to enable and optimize uplink and downlink 4G processing. The position is flexible in both duration and hours. The role can be a full-time permanent hire, a full-time contract position, or a part-time consulting position. This role can be located anywhere in the world.

You Will Make an Impact By
Providing hands-on development and debug support for B4860 MAPLE hardware accelerators
Supporting uplink (UL) MAPLE modules and MAPLE job scheduling
Developing, modifying, and troubleshooting MAPLE RISC micro-code, including state machines and DMA coordination between master and slave components
Developing and maintaining embedded firmware to control MAPLE accelerators
Writing and supporting device drivers for MAPLE accelerators (DEPE, EQPE, FTPE, TVPE, PUPE, CRCPE) on SC3900 DSP cores
Configuring and troubleshooting shared memory subsystems and cache coherency between MAPLE accelerators and SC3900 DSP cores
Debugging MAPLE hangs caused by memory corruption, coherency issues, or performance bottlenecks
Supporting B4860 exception handling, system configuration, and MMU configuration for both SC3900 DSP cores and MAPLE accelerators
Configuring and debugging MAPLE AXI master and slave interfaces to/from the SoC
Supporting CoreNet Coherency Module configuration and resolving system-level issues
Working with MAPLE HW scheduler, PIC, and SRAM switch fabric on B4860 platforms
Required Qualifications for Consideration
Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent practical experience
Proven hands-on experience with Freescale B4860 MAPLE hardware and/or MAPLE software
Prior experience working on MAPLE HW and/or MAPLE SW is required
Strong experience with UL MAPLE modules (must-have)
Experience developing RISC-based embedded firmware for hardware accelerators
Experience writing low-level device drivers for DSP-based systems
Strong understanding of DMA, MMU configuration, cache coherency, and shared memory architectures
Demonstrated ability to debug complex hardware/software interaction issues in real-time or near-real-time systems
You Will Excite Us If You
Have experience with SC3900 DSP processing
Understand Host-to-MAPLE interfaces, including job preparation, MAPLE buffer descriptors, and SDOS APIs
Have worked with EDF / Embedded Data Flows in MAPLE engines
Have experience configuring high- and low-priority buffer descriptor rings
Have hands-on experience with B4860 Datapath Acceleration Architecture (DPAA), including QMAN, BMAN, and FMAN
