Electronics Engineer (Embedded Systems)

What you'll actually own

You keep Zooly's sensor electronics real and reliable: hardware development, PCB design, schematics and layout, firmware development, board bring-up, sensor characterization, test fixtures, and production test across the hip, knee, and shoulder products. Your hands are on the hardware that every measurement depends on. You work on one shared platform, so the fixtures and methods you build get used everywhere. The best hardware here is creative and simple at once. If our sensing holds up in the lab and on the line, it will be in part because of the electronics work you did.

Where the business is 12 months after you join

If this hire goes the way we intend, one year from now:

• You have shipped platform electronics work that the hip, knee, and shoulder products rely on.
• Your test fixtures and calibration utilities are what the team uses to trust its hardware.
• You deliver predictably within the shared platform cadence.

About Zooly

Zooly Labs is on a mission to make advanced surgical guidance more accessible for joint replacement surgery. Joint replacement can restore mobility and quality of life, yet surgeons often have limited objective information during the procedure to assess joint behavior and guide decisions. We build AI-guided technology that combines intelligent sensing, real-time data, and decision support with familiar surgical workflows and standard instruments, without large capital equipment. We are an early-stage company building a scalable platform across hip, knee, and shoulder.

How we work at Zooly

Patient-driven. Design-obsessed. We're an in-person team of curious, driven people who care about getting the details right, because there's a patient on the table counting on us. A few beliefs shape how we build, and this role lives at the center of them.

• Build it together. We want people who want to be in the room, solving hard problems face to face. The camaraderie is not a perk, it is how we do our best work.
• Master your craft. We invest in people who go deep. There is no ceiling that forces a great engineer or designer into management to advance. Go as far into your craft as you want.
• Act like an owner. We take responsibility for our decisions and how we communicate, we think long-term, and we bias toward action.

What this role is really like

This is a hands-on role at a fast-growing startup racing real deadlines. You will bring up a board with a scope and logic analyzer, characterize a sensor, write a calibration utility, and build a manufacturing test, often in the same week. If you want to stay in schematic capture and never touch the bench, this is not the role. If you love making real hardware work, it is.

What you'll do

• Develop and support schematics, PCB updates, board bring-up, debugging, sensor characterization and integration, embedded tests, calibration utilities, and manufacturing tests.
• Build reusable platform modules instead of one-off, joint-specific solutions wherever you can.
• Take part in sprint planning, design and code reviews, test planning, and documentation.
• Investigate defects and failures and document root cause and fixes.
• Keep configuration control, test evidence, and clean engineering records.
• Work closely with the product engineers, the US platform leads, quality/regulatory contributors, and suppliers.

What you need to be able to do

These are capabilities, not credentials. If you can do these things, we want to talk regardless of how many years it took you to get here.

• You have hands-on experience with embedded electronics, sensor systems, PCB development, firmware-adjacent work, or hardware verification.
• You can do schematic development, PCB layout review, board bring-up, and work with microcontrollers, analog/digital interfaces, power systems, batteries, and wireless.
• You debug fluently with oscilloscopes, logic analyzers, multimeters, and power analyzers.
• You have working knowledge of embedded C/C++, communication protocols, test scripting, and automated hardware characterization.
• You troubleshoot well, document clearly, keep configuration control, and collaborate with suppliers.
• A degree in electronics and communication engineering or electrical engineering is common in people who do this well, but the ability above matters more than the diploma.

What would make you a strong fit

• Experience with medical devices, robotics, wearables, IoT, or other high-reliability sensor-enabled products and intricate devices.
• Experience with IMUs, force/pressure/strain sensors, sensor calibration, low-power wireless, or production-test automation.
• Experience with Altium, KiCad, OrCAD, or comparable ECAD tools.
• Exposure to EMC testing, pilot manufacturing, component qualification, or design controls.

How this role works with the rest of the team

You are part of one shared engineering team. You are based in India, but the backlog, architecture, and design reviews are global. You work closely with the US electronics and product engineers across overlapping hours, and your work serves every product, not a single joint.

Stay curious

We hire curious people. The kind who took things apart as kids and never stopped asking how things work. If that sounds like you, we'd love to meet.
