About Bytebeam

Bytebeam builds the hardware and software stacks that power the next generation of smart connected vehicles. From device telemetry and remote diagnostics to OTA updates, alerts, and fleet-scale device management, Bytebeam helps teams ship connected products faster and operate them reliably in the field.

At Bytebeam, hardware does not stop at schematics or layout. We care about how the board behaves in the vehicle, how it gets assembled in production, how it survives EMI, vibration, heat, weak power, field wiring, and how quickly engineering can debug the next issue.

Role Overview

We are hiring a PCB Designer to own PCB layout and release-quality design outputs for our automotive telematics devices.

This is a hands-on production hardware role. You will work from schematics, requirements, mechanical constraints, and manufacturing inputs to create clean, manufacturable PCB layouts for connected vehicle devices. You will work closely with hardware, firmware, validation, mechanical, sourcing, PCB fabrication, and EMS partners to take boards from design through prototypes, bring-up, design revisions, and production release.

We are looking for someone who is strong in Altium Designer, understands electronics well enough to make good layout tradeoffs, and cares deeply about details that decide whether a board works the first time.

What You'll Do

1) PCB Layout and Design Execution

- Own PCB layout for automotive telematics boards from placement through routing, review, and release.
- Translate schematics, board outlines, connector positions, antenna zones, mechanical keepouts, and manufacturing constraints into clean board layouts.
- Define and maintain layout rules for multilayer boards, including stack-up constraints, controlled impedance, differential pairs, spacing, clearances, length matching, and return paths.
- Route mixed-signal embedded hardware with attention to MCUs/MPUs, cellular/LTE modules, GNSS, BLE/Wi-Fi, CAN/OBD, CAN FD, RS-485, USB, Ethernet, SDIO/eMMC, SIM/eSIM, sensors, backup battery, power, debug, and test interfaces.
- Build and close layout constraints for critical nets such as USB, Ethernet/RGMII, SDIO/eMMC, DDR/LPDDR where applicable, RF feedlines, clocks, and high-current power paths.
- Make placement and routing decisions that reduce EMI/EMC risk, improve signal quality, protect sensitive analog/RF paths, and keep power loops and return paths sane.
- Avoid layout mistakes that cause high-speed failures: stubs, split-plane crossings, asymmetric differential-pair vias, missing return paths, poor decoupling placement, uncontrolled impedance, and avoidable crosstalk.

2) High-Speed, RF, and Antenna Layout

- Route high-speed interfaces with controlled impedance, length/skew matching, differential-pair symmetry, crosstalk spacing, via minimization, and continuous reference planes.
- Plan layer transitions for critical signals with symmetric vias and nearby ground-return stitching vias.
- Design or review 50 ohm RF feedlines for cellular/LTE, GNSS, BLE/Wi-Fi, and antenna connections using the stack-up agreed with the PCB fabricator.
- Place RF matching networks, RF connectors, antenna keepouts, ESD protection, ground stitching, and via fences so wireless performance is not sacrificed late in the design.
- Keep RF paths away from crystals, high-speed clocks, switching regulators, noisy digital traces, copper intrusions, and mechanical metal that can detune antennas.
- Support antenna tuning, GNSS/cellular performance debug, and EMI/EMC pre-compliance changes with the hardware and validation teams.

3) Automotive Layout, Protection, and Compliance Readiness

- Layout vehicle power-input and protection sections with attention to load dump, jump start, cranking, reverse polarity, ESD, surge, high-current paths, heat, and safe spacing.
- Place TVS diodes, filters, common-mode chokes, termination parts, protection parts, and connectors so vehicle-facing interfaces are robust and testable.
- Route CAN, CAN FD, OBD, RS-485, and other vehicle or field interfaces with a clear understanding of termination,



bus protection, EMC, and connector-adjacent protection placement.
- Design PCB layouts with automotive realities in mind: vibration, thermal cycling, connector stress, harness variation, exposed field wiring, long service life, and EMS process variation.
- Keep layouts reviewable against relevant standards and checklists such as IPC design practice, IPC land-pattern practice, IPC automotive addenda where applicable, CISPR 25, ISO 7637, ISO 10605, and ISO 16750.

4) ECAD Library, Footprints, and Documentation

- Create, verify, and maintain symbols, footprints, 3D models, and reusable ECAD library parts.
- Cross-check footprints against datasheets, land-pattern guidance, package drawings, and assembly constraints.
- Generate complete manufacturing and assembly release packages, including Gerbers, ODB++ where required, drill files, pick-and-place files, assembly drawings, fabrication notes, stack-up notes, and BOM inputs.
- Maintain clear revision records, layout notes, checklist closures, and ECO documentation.
- Keep design files clean enough that another engineer can review, reuse, or revise them without archaeology.

5) Manufacturability and Vendor Coordination

- Work with PCB fabrication and EMS partners to close DFM, DFA, and DFT feedback before release.
- Review stack-up, material, copper weight, impedance targets, panelization, solder mask, silkscreen, test-point access, and assembly constraints.
- Incorporate feedback from fabrication, assembly, sourcing, validation, and production builds into the next PCB revision.
- Support alternate component and footprint decisions when supply-chain or lifecycle issues affect layout.
- Help improve Bytebeam's PCB checklists, layout guidelines, library practices, and release workflow.

6) Design Review, Bring-Up, and Issue Closure

- Participate in schematic and layout reviews with hardware, firmware, mechanical, validation, and manufacturing teams.
- Support board bring-up by helping inspect layout-sensitive issues around power, interfaces, RF, grounding, noise, connectors, thermal behavior, and manufacturing defects.
- Use board files, schematics, datasheets, and lab observations to help debug prototype and production issues.
- Work with the hardware and validation teams to identify root cause and close layout-related changes in the next revision.
- Build a feedback loop from bring-up, EMI/EMC testing, reliability testing, EMS feedback, and field issues into better future layouts.

Deliverables You'll Own

- PCB layouts and release-ready ECAD design files
- PCB stack-up, design rules, placement/routing notes, and layout-review closure
- High-speed and RF constraint records: impedance targets, length/skew tables, spacing rules, return-path notes, antenna keepouts, and RF-routing notes

- Symbols, footprints, 3D models, and reusable library assets

Who We Are Looking For

We are looking for a PCB Designer who treats layout as engineering work, not drawing work. You should enjoy the discipline of getting placement, return paths, test access, fabrication rules, and mechanical constraints right before the board goes out.

This role will fit someone who can sit with a hardware engineer, challenge a risky connector placement, RF keepout violation, uncontrolled high-speed route, or power-loop path, talk constructively to a PCB fabricator or EMS partner, and then turn the feedback into a cleaner board revision. You should care about boards that assemble cleanly, debug cleanly, and survive real vehicle deployment.

Application Note

Send us one PCB you designed or substantially owned. Tell us the layer count, tool used, major constraints, high-speed or RF sections if any, what went wrong during fabrication, assembly, bring-up, RF/antenna testing, or EMI/EMC testing, and what you changed in the next revision. Layout screenshots, fabrication notes, photos, or a short portfolio are welcome.
