R&D Engineering Technician
Join Us in Building the Future of Home Robotics
At Sunday, we're developing personal robots to reclaim the hours lost to repetitive tasks. We're focused on an ambitious goal to make generalized robots broadly accessible, enabling households to take back quality time.
We have spent the last 18 months building a talented team, securing capital, and validating our technology. We are now seeking passionate individuals to join us in the next phase of our growth. If you are ready to apply your skills to the forefront of robotics innovation, we’d love to hear from you.
What to Expect
In building robots for the home, we are tackling a true grand challenge in robotics: dexterous mobile manipulation in unstructured environments. To make this possible, we are building across the entire robotics stack, and a lot of that work happens at the bench.
As an R&D Engineering Technician, you'll be working hands on turning designs and test plans into working hardware. You'll partner closely with our systems, mechanical, electrical, and firmware engineers to build, wire, bring up, and test robots and subsystems. You will also help us keep our fleet of robots well maintained and continuously improving. This role offers significant ownership and a front row seat to cutting edge technology as it comes together into a real product.
What You'll Do
Assemble, wire, and bring up robotic systems and subsystems including actuation and perception hardware, following engineering drawings and work instructions
Execute test plans and procedures developed by engineers; collect, log, and organize test data
Build, maintain, and improve test fixtures and jigs
Run standard test equipment (oscilloscope, multimeter, logic analyzer) under engineering direction, to triage and debug issues
Support cross disciplinary triage spanning mechanical, electrical, firmware, and software systems, escalating findings to the responsible engineers
Aid our early robot deployments by going on site and potentially being on-call
Document build logs, write standard operating procedures, and surface recommendations to engineers
Perform soldering, crimping, rework, and light fabrication to support prototyping and repair
Maintain lab equipment, tools, inventory, and consumables; keep the workspace organized, calibrated, and safe
Provide feedback and work on improvements to robot assembly, bringup, and QA processes
Use basic scripting (Python) to run test routines or parse data where it speeds the work
What You'll Bring
2+ years of hands on experience building and testing robots (or complex electromechanical systems - those are robots too!)
Ability to read and work from schematics, mechanical drawings, BOMs, and work instructions
Comfort with soldering, crimping, hand tools, and basic mechanical/electrical fabrication and assembly
Familiarity with standard diagnostic tools (oscilloscope, multimeter, logic analyzer)
Strong, detail-oriented record keeping and a habit of clear documentation
Comfort working in a fast-moving prototype environment
Nice to Haves
Exposure to protocols including CAN, Ethernet, USB, MIPI
Hands on experience with actuators, cameras, microcontrollers
Soldering and rework to IPC standards
Comfortable with agentic coding tools (Claude Code, Codex, etc.)
Prior experience in a robotics startup
At Sunday Robotics, we’re building technology shaped by real people - curious, creative, and diverse. We’re proud to be an equal opportunity employer and consider all qualified applicants regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.
Even if you don’t meet every single requirement, we encourage you to apply. Studies show that women and underrepresented groups often hold back unless they meet 100% of the criteria - we don’t want that to be the reason we miss out on great talent.
