Position: Full-Time Direct Hire

Overview
TalentFish is casting a line for an Electrical Systems Engineer - Embedded HW/FW & Support! We are seeking a hands-on Electrical Systems Engineer to lead electrical system design while contributing to firmware factory support returns (RMA) touch sensor tuning and customer support with our client.

What Youll Do - Role Responsibilities:

Electrical system design (35%)

1. Lead schematic capture PCB-level electrical design and component selection for new products and revisions.

1. Design analog and digital circuits power delivery signal integrity considerations and EMC mitigation strategies.
2. Produce and review design documentation BOMs and verification plans.
3. Work closely with mechanical software and test engineering to ensure system-level integration and reliability.

Firmware development (15%)

1. Implement and maintain embedded firmware features tied to electrical interfaces and sensors.
2. Debug hardware/firmware interactions and provide targeted fixes or workarounds in collaboration with firmware engineers.
3. Contribute small-to-moderate firmware changes focused on enabling hardware functionality and resolving integration issues.

Factory support (10%)

1. Support manufacturing ramp-up: review test fixtures create/validate production test procedures and troubleshoot production issues.
2. Work with contract manufacturers to clarify assembly and test requirements and implement corrective actions to improve yield.

RMA support (5%)

1. Investigate returned units to root-cause hardware failures and interact with firmware and test teams as needed.

Develop and document repair procedures failure modes and preventative design changes to reduce return rates.

Touch sensor tuning (20%)

1. Tune and validate touch sensor performance (capacitive or other touch technologies) across hardware revisions and environmental conditions.

Develop tuning procedures thresholds and baseline algorithms and verify performance in lab and field scenarios.

Customer support (15%)

1. Serve as a technical escalation for customers partners and support teams on electrical and touch-sensor related issues.
2. Provide actionable troubleshooting steps documentation and firmware/hardware recommendations to resolve customer-impacting problems.

Time Allocation for primary responsibilities

1. Electrical circuits boards and system designs and test debug - 35%
2. Touch sensor tuning and designing (capacitive/gesture/etc.) - 20%
3. Customer support (technical escalations pre and post sale) - 15%
4. Firmware development - 15%
5. Factory support - 10%
6. RMA (returns & repairs) support - 5%

What Youll Bring - Your Qualifications:

1. Degree in Electrical Engineering Electronics Engineering Technology or equivalent experience.
2. Demonstrated experience in electronic system design (schematic capture PCB design component selection) for power board to board communications and peripherals with EMC/EMI in mind.
3. Practical experience debugging hardware and hardware/firmware interactions.
4. Basic embedded firmware knowledge (C/C) and build tools and experience with peripheral interfaces (I2C/SPI/UART); Experience designing building controlling and deploying FW for production environments
5. Experience using electrical engineering tools and test equipment
6. Familiarity with production test development and supporting manufacturing.
7. Experience investigating RMAs and implementing corrective actions.
8. Strong communication skills for cross-functional collaboration and customer-facing interactions.

Preferred Skills

1. Experience tuning and validating touch sensors (capacitive or comparable technologies).
2. Proficiency with common PCB layout tool(s) and workflows.
3. Experience with power supply design signal integrity EMC/EMI testing.
4. Experience working with contract manufacturers and production test systems.
5. Familiarity with test automation and data-driven failure analysis.

What You Can Expect
Working Conditions & Expectations:

1. Hands-on lab work with prototypes and production hardware/fw.
2. Occasional onsite presence at manufacturing or test facilities or customer site as needed
3. Collaboration across firmware mechanical electrical sales QA project management customers and contract manufacturers.
4. Switching gears and focused on prioritized outputs

What this job is:

• Hands on everyday
• Independent and collaborative
• 20 customer projects/products per year; short design cycles lots of shifting between projects and priorities
• Interfacing customers to produce customer requirements
• Process oriented
• Figuring new stuff out
• Creating Documentation
• For an individual contributor owner and SME for all electrical system and circuit designs from concept to production new designs and existing designs with factory customer and field support
  • Must have recent experience designing circuits with microcontrollers from scratch (analog and digital) using a schematic capture tool and releasing products to production as the owner for at least 5 years and 5 products. A role where products were designed for internal use is not relevant/ideal for comparable experience.
• Prefer to have Altium expertise in schematic capture and layout.
• FW engineer owning all embedded fw development control/release sensor tuning and factory support. Must have built firmware for microcontrollers from conception to production for at least 5 products for a company selling embedded hardware products that are released to the field.
• Must have experience controlling designs electrical and firmware.

What this job isnt:

• One product project per year long design and build cycle
• A support EE/FW person 1 of many EE/FW
• Slow pace low urgency procrastination micromanagement required
• A management position

• Opportunity to drive core electrical and fw designs and see the product through manufacturing integration into customer product and field support.
• A cross-functional role with technical variety spanning hardware firmware manufacturing and customer interaction.
• Opportunities to integrate new technologies to increase the organizations HMI offerings and bring fast growth to your tech skills.
