Senior Hardware Design Engineer

GrubPac builds electric last-mile delivery infrastructure — EV two-wheeler fleets fitted with our own connected, temperature-controlled Smart Boxes for cold-chain delivery. Commercial pilots with two of India's largest food and dairy brands go live in January 2027.
We're bringing our electronics design capability in-house. This role owns it.
What you'll do
Own the full PCB cycle for the Smart Box: architecture, schematic capture, multi-layer layout, fab and assembly release
Become the source of truth for our hardware — complete schematic, layout, BOM and revision documentation for existing and new boards
Redesign current hardware for cost, reliability, component consolidation and manufacturability at fleet scale
Design and validate power across both variants: DC architectures with battery management, and AC compressor-driven units on direct 170–240V mains
Integrate temperature/environmental sensing, GPS-LTE telemetry and display control; work with our firmware team on interface definition and bring-up
Run bench, thermal and vibration validation plus field failure analysis on units riding Indian roads
Manage EMS and component vendors from prototype through production ramp, and drive EMI/EMC and BIS compliance
What we're looking for
4–8 years designing production electronics that shipped in volume — IoT, embedded, automotive, appliance or power electronics
Strong Altium / KiCad / OrCAD skills across schematic and multi-layer layout
Mixed-signal and power fundamentals: SMPS, DC-DC, BMS, compressor/motor control, protection circuits
Hands-on ability to analyse, document and improve existing boards on the bench
IPC standards, DFM/DFA, EMI/EMC and thermal design; comfort with scope, logic analyser and thermal camera
Experience with Indian EMS and component suppliers
B.E./B.Tech in Electronics, Electrical or related (we prioritise skills over degrees)
Bonus: cold-chain or HVAC control systems, ruggedised/IP-rated hardware, embedded C literacy, or having stood up a hardware function at a startup.
CTC: As per industry standards, commensurate with experience.
You won't be iterating on a component of a component. You'll own the electronics of a product going into commercial fleet deployment in January 2027 — and have the authority to change it.
On-site, Delhi. Applications with a portfolio, board photographs or design samples will be prioritised.
