À propos
We have an existing KiCad-based hardware design for a digital audio device intended for professional cinema environments. The system extracts LTC Linear Timecode embedded on AES3 channel 16 from a bundled RJ45 connection using the AES72 pinout, while maintaining a transparent pass-through of the full upstream AES signal path. (The device must preserve full AES signal integrity between upstream and downstream devices, without introducing audible degradation or clock instability.)
The current design includes:
- Full schematic in KiCad
- PCB layout
- Bill of materials
- AES3 receiver using CS8416
- RS-422 receiver stage
- I2S routing to PCM5102A DAC
- Analog LTC output stage
- Power supply stage
We are seeking a senior hardware engineer for the following:
Phase 1 – Design Review and Prototype Bring-Up
- Review schematic for correctness including AES3 handling, impedance, clocking, and power integrity
- Review PCB layout including differential routing, trace impedance, and grounding
- Validate LTC extraction architecture
- Prepare board for fabrication
- Oversee prototype assembly
- Assist with bring-up and signal validation
- Confirm LTC and pass-through signal integrity on output
Deliverables for Phase 1:
- Validated schematic and PCB
- Updated production-ready bill of materials
- 1-2 assembled working prototype units
- Bring-up notes and test documentation
Phase 2 Optional Separate Contract:
- Small batch production three to ten units
- Mechanical enclosure refinement
- Assembly documentation
Ideal Candidate:
- Strong digital audio experience including AES3 and I2S
- KiCad fluency
- Experience with mixed-signal PCB layout
- Experience supervising prototype fabrication
- Comfortable working without access to proprietary cinema hardware and able to simulate AES input in a lab environment
Contract duration of 1 to 3 months. with 30 hours per week.
Mandatory skills: PCB Design, Circuit Design, Electronics, Electronic Design, Electrical Engineering, Digital Electronics, Embedded System, Hardware Design
