Company

hirify.global develops semiconductor solutions and optical digital signal processing products used in cloud, AI, carrier, and data-center infrastructure.

What you will do

• Architect, design, develop, and test embedded C firmware for complex DSP hardware running on a RISC-V-based multicore MCU.
• Develop firmware for RX/TX signal processing, FEC, PLL/FLL, reference generation, and thermal monitoring.
• Review firmware architecture, APIs, and system integration approaches, translating MSA, OIF, CMIS, and customer specifications into development requirements.
• Debug hardware-software issues, identify root causes, and coordinate validation, testing, and customer support.
• Plan software milestones, manage Agile sprints and backlog priorities, and coordinate deliverables with Marketing, AE, Test, Validation, QA, and Hardware teams.
• Support customer bring-up and develop customer-specific features such as FEC burst statistics, VDM telemetry, and CMIS compliance.

Requirements

• Experience developing memory-constrained embedded C/C++ firmware from architecture and design through testing and customer volume production.
• Understanding of embedded SoC and microcontroller architecture, memory-mapped hardware interfaces, GPIOs, and interrupt service routines; RISC-V experience is advantageous.
• Excellent verbal and written communication skills in English and the ability to collaborate across a large cross-functional organization.
• Bachelor’s, master’s, or PhD degree in Computer Science, Electrical Engineering, Software Engineering, or a related technical field.
• Eligibility to access technology subject to U.S. export-control laws may be required; applicants may undergo an export license review.

Nice to have

• Experience with SERDES, optical DSP, Ethernet or PCIe PHYs, optical module software, FEC, PCS/PMA/PMD, PRBS, and PHY traffic schemes.
• Experience with bare-metal systems, RTOS, device drivers, Linux kernel development, state machines, mixed-signal control, or PID feedback loops.
• Proficiency in C and Python, with Git, Linux, makefiles, GDB, IDEs, Bash, and Clang/GCC.
• Familiarity with digital verification, FPGA emulation, Verilog, laboratory equipment, and signal-processing concepts such as BER, SNR, FFT, and sampling phase.

Culture & Benefits

• Full-time employment with comprehensive benefits supporting financial well-being, family support, mental health, physical health, and recognition.
• Employee stock purchase plan with a two-year look-back period.
• Family support programs, mental health resources, and recognition and service awards.
• Interview participation must be unaided by AI tools, transcription applications, automated note-taking bots, or real-time answer generators.
