Embedded Hardware Engineer

About us

We're an early stage startup in stealth mode in Mumbai, building a security first service that protects people's most valuable possessions. At its core is a secure, connected, battery powered device that we design in-house.

The role

We're hiring the engineer who will own the device's electronics, from the first prototype to a design ready for manufacturing.

What you'll do

• Own the electronics end to end: architecture, schematics, PCB layout, bring-up and firmware

• Design the power system around a rechargeable battery, with low power modes and safe charging

• Integrate 4G cellular, biometric sensing, an electronic lock and other sensors

• Build security into the hardware: secure element, secure boot and signed firmware updates

• Work side by side with our mechanical engineer on fit and assembly, and with our backend engineer on how the device talks to our servers

• Test, debug and document each prototype, and get the design ready for manufacturing and certification

What you'll bring

• 3+ years in embedded hardware and firmware, including at least one battery-powered connected product that reached production

• Schematic and PCB design (KiCad, Altium or similar), and firmware in C/C++ on ESP32, STM32 or similar

• Hands-on work with 4G/LTE modules and low-power design

• Confident in the lab: oscilloscope, logic analyser, soldering and board rework

Good to have

• LiFePO4 batteries and BMS design

• Secure elements, secure boot or encrypted OTA updates

• Fingerprint sensors, solenoids or motor drivers

• Taking a product through BIS, WPC or similar certification

How we work

• Contract for the prototype phase at full-time hours, with a path to a full-time role

• Competitive pay, all in cash (no ESOPs)

• On-site in Mumbai, with the hardware

• You work directly with the founder, and what you design is what ships

Please apply only if you've designed the PCB and written the firmware for a battery powered product that reached production. Shortlisted candidates will walk us through a board they designed.
