Electrical Engineer Internship Startup Jobs in Massachusetts

You will architect and own our analog and power electronics, oversee PCB development from schematic to production, lead embedded firmware efforts, and build the sensing and validation infrastructure needed to run our process reliably at scale. You will work directly with the founding team, set technical direction for the electrical discipline, and mentor engineers as the team grows.

• Want to architect something genuinely new. You will design from the ground up in a space that has no existing playbook.
• Are energized by constraint. Tight budgets, hard deadlines, and novel physics all at once. You perform well under those conditions and bring others along with you.
• Take end-to-end technical ownership. From initial architecture to bring-up, validation, and production readiness, you drive it across the finish line and hold the standard.
• Want to have an impact on decarbonizing manufacturing. You understand that more efficient processes and lighter parts have real consequences at scale.
• Are a clear communicator and technical leader. You can explain your electrical choices across technical disciplines and make the people around you better.

• Define and own the electrical architecture for a novel metal additive manufacturing platform, from system-level requirements through prototyping, validation, and production readiness.
• Lead design and simulation of analog and power electronics circuits, ensuring performance, reliability, and safety across operating conditions.
• Own PCB design and layout from schematic capture through fabrication and bring-up, applying best practices for signal integrity, EMC, thermal management, and design for manufacturability.
• Develop embedded firmware for real-time control and monitoring of the system's electrical subsystems, interfacing with sensors, actuators, and motion hardware.
• Define and execute electrical verification and validation procedures, including functional testing, design review, and FMEA.
• Specify and qualify electronic components and subsystems for reliable operation in demanding manufacturing environments.
• Collaborate with mechanical, controls, software, and process engineering to ensure clean system-level integration.
• Establish and own electrical documentation standards: schematics, BOMs, design review records, and test reports.
• Contribute to IP development and support patent preparation in collaboration with the founding team.
• Mentor and guide junior engineers and interns as the team scales.

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field; Master's or PhD a plus.
• 5+ years of hands-on experience designing and developing electronic hardware, with demonstrated progression of technical responsibility.
• Deep proficiency in analog and power electronics design.
• Experience with PCB design and layout (KiCad, Altium, or equivalent), from schematic through production-ready files.
• Embedded firmware development experience and familiarity with real-time control systems.
• Experience defining and executing electrical V&V procedures, including functional testing and design review processes.
• Demonstrated ability to take hardware from concept through build, test, and iterative improvement, ideally across multiple product generations.
• Prior experience in a hardware startup, industrial equipment, or advanced manufacturing context.

• Background in FPGA, DSP, or real-time embedded platforms.
• Familiarity with design for manufacturability (DFM) and design for test (DFT) principles.
• Exposure to FMEA, functional safety standards, or electrical regulatory compliance (IEC, UL, CE).
• Experience managing or mentoring other engineers.
• Interest in metal additive manufacturing or advanced manufacturing processes.

• Y Combinator and NSF-backed startup with differentiated, defensible technology.
• Equity incentive based on long-term contributions and performance.
• Direct collaboration with the founding team on hardware that does not exist elsewhere in the world.
• A lean, low-bureaucracy environment where your technical judgment shapes product direction.
• Flexible working arrangements and a culture that respects your time and autonomy.
• The opportunity to file patents and contribute to a growing IP portfolio in a novel technical domain.
