Job summary

PASCALL Systems, a Cambridge-based medical device company, seeks an experienced hardware engineer to own electronics execution end-to-end, including PCB layout, test coordination, and documentation. You’ll work with the COO/VP Engineering and external partners to drive hardware shipped to market.

Ideal candidates have 3–5 years hands-on electronics experience, strong analog/mixed-signal design skills, and comfort coordinating with suppliers and ISO‑13485 test houses. Hybrid work possible.

Qualifications

• Bachelor's degree in Electrical Engineering, Biomedical Engineering, or related field.
• 3–5 years hands-on electronics experience.
• PCB schematic and layout experience.
• Strong fundamentals in analog/mixed-signal circuit design — filters, signal conditioning, power management.
• Experience with suppliers and vendors — specs, issue resolution, delivery tracking.
• Comfort using AI-assisted tools (e.g., GitHub Copilot, Claude / Claude Code, ChatGPT, Cursor) for engineering and documentation work.

Responsibilities

• Design, prototype, and characterize analog and mixed-signal circuits — filters, signal conditioning, and power management — supporting EEG signal acquisition.
• Own PCB schematic & layout for test circuits and prototype hardware.
• Select and characterize electronic components against design requirements.
• Support hardware/firmware integration and debug across device subsystems.
• Manage day-to-day supplier relationships — electrode patch and other hardware suppliers.
• Coordinate testing schedules with ISO 13485 test houses.
• Design and execute experiments to validate hardware performance and analyze data.
• Perform quality control testing using circuit-level analysis techniques.
• Coordinate hardware work across firmware, algorithms, and external consultants.
• Document designs, test protocols, and vendor specifications.
• Use Python for basic data analysis and signal processing on test results.
• Mentor interns on hardware fundamentals and lab practices.
• Use AI-assisted tools to accelerate development tasks.
• Apply AI tools responsibly within a regulated development environment.

Job description

Position Summary

PASCALL is building the next generation of our EEG-based brain state monitoring platform, and we need someone who can own the electronics and hardware execution end-to-end — not just design circuits, but drive the surrounding work (vendor relationships, test coordination, documentation) that actually gets hardware shipped. This role exists to take that ownership off our current Lead Hardware Engineer's plate as the platform scope grows, with the electronics depth to keep pace on circuit and PCB work and the initiative to run with ambiguous problems.

You’ll work closely with our COO/VP Engineering (EE background) and our firmware and systems engineering team, and directly with external partners — electrode patch suppliers, ISO 13485 test houses, and contract engineering firms. You’ll own PCB schematic/layout work on test and prototype circuits, day-to-day supplier and test-house coordination, and the technical documentation that ties it together. This is a high-ownership role for someone ready to grow into more scope, not a narrowly-scoped component-selection job.

PASCALL actively uses agentic AI tools to accelerate development, documentation, and hardware test workflows. We welcome engineers who are comfortable experimenting with AI-assisted workflows and applying them responsibly in a regulated environment.

Responsibilities

• Design & Characterize Circuits: Design, prototype, and characterize analog and mixed-signal circuits — filters, signal conditioning, and power management — supporting EEG signal acquisition.

• Own PCB Schematic & Layout: Develop and iterate PCB schematics and layouts for test circuits and prototype hardware.

• Select Components: Select and characterize electronic components against design requirements (tolerance, thermal, power).

• Support Integration & Debug: Support hardware/firmware integration and debug across device sub-systems.

• Manage Supplier Relationships: Own day-to-day relationships with electrode patch and other hardware suppliers — specs, quality issues, delivery tracking.

• Coordinate Test Houses: Coordinate testing schedules and deliverables with third-party ISO 13485 test houses.

• Design & Run Experiments: Design and execute experiments to validate hardware performance, including use of physiological signal generators/simulators, and analyze resulting data.

• Perform QC Testing: Perform quality control testing using circuit-level analysis techniques.

• Coordinate Cross-Functionally: Coordinate hardware-related work across firmware, algorithms, and external consultants (mechanical design, contract engineering).

• Document Rigorously: Produce and maintain technical documentation for designs, test protocols, and vendor specifications.

• Analyze Data: Use Python (or similar) for basic data analysis and signal processing on test results.

• Mentor Interns: Mentor interns on hardware fundamentals and lab practices as needed.

• Use AI-assisted tools (e.g., LLM-powered coding assistants, automated documentation) to accelerate development tasks.

• Apply AI tools responsibly within PASCALL's regulated development environment.

• Comfortable working directly with suppliers and vendors — specs, issue resolution, delivery tracking

• Self-directed, with a track record of taking on increasing scope and responsibility

• Comfort using AI-assisted tools (e.g., GitHub Copilot, Claude / Claude Code, ChatGPT, Cursor) for engineering and documentation work

Preferred

• Experience with low-power or battery-powered wearable/biosignal‑acquisition hardware

• Exposure to ISO 13485 or other regulated medical device development environments
