Mechanical Technician

About the team

Droyd builds autonomous robotic systems that automate repetitive manual work in real environments. Our robots are built in-house, which means fabrication, iteration, and shop execution are core to how we operate.

Our hardware team designs and builds low-cost six-axis robotic arms used to train and deploy generalist AI models. The shop is where designs become real parts.

About the role

As a Shop Technician / Machinist (Entry Level) at Droyd, you’ll support day-to-day in-house fabrication for our robotics team. You’ll run CNC equipment, operate advanced 3D printers, and produce reliable prototype and production parts.

This is an entry-level, hands-on role designed for someone early in their career who wants to grow into a senior fabrication or manufacturing position. You’ll work closely with mechanical engineers and learn directly on real hardware.

This role is based on-site in San Francisco, CA.

In this role, you’ll

Additive manufacturing

• Operate and maintain a fleet of Bambu Lab printers (H2D and P1S) with multi-material capability

• Set up prints using engineering filaments such as PPA-CF, PC, ASA, and PETG-CF

• Tune slicing for strength, dimensional accuracy, reliability, and material efficiency

• Manage filament drying, storage, and material handling

• Own the full print workflow including setup, monitoring, post-processing, and finishing

• Perform annealing and other thermal post-processing for high-performance polymers

CNC machining

• Program and run 3-axis and 4-axis CAM operations for aluminum parts

• Operate in-house CNC equipment including AVID routers and a Makera Carvera mill

• Plan workholding, design fixtures, and prepare part setups

• Perform routine maintenance such as calibration, tramming, lubrication, and tool changes

CAD, CAM, and fixturing

• Create simple CAD models for fixtures, jigs, and prototypes (Onshape preferred)

• Generate CAM toolpaths for router-style CNC systems and small mills

• Design custom fixtures for unconventional geometries

General shop operations

• Operate core shop tools such as drill presses, saws, sanders, and deburring tools

• Help keep the shop safe, organized, and running smoothly

• Support inventory tracking for tooling, consumables, and raw materials

• Learn and grow into operating additional equipment as the shop scales

Vendor coordination

• Assist with communication and coordination with external machine shops and fabricators

• Help manage outsourced machining and specialty fabrication work

We’re looking for candidates who

• Are early in their career and looking for an entry-level role in fabrication or machining

• Have hands-on experience from school shops, internships, maker spaces, or personal projects

• Are comfortable working with tools, machines, and physical hardware

• Want to learn CNC machining, additive manufacturing, and shop best practices

• Take pride in clean, reliable work and attention to detail

• Are eager to grow into more responsibility over time

About Droyd

Droyd builds autonomous robotic systems to automate manual work for enterprises. We design the hardware, build it in-house, and deploy robots that operate in real production environments.

If we do this right, robots stop being prototypes and start being infrastructure.

Join us and help build the hardware that makes it real.
