About EMTensor

EMTensor develops electromagnetic (microwave) tomography systems for brain imaging — scanners that detect and monitor stroke at the bedside and in the ambulance. We are headquartered in Vienna, Austria, with an engineering office in Bengaluru, India. The team is small, so the engineer who designs something owns it end to end.

The Role

You own the circuit design of our mixed-signal boards: an analogue front end, an RF chain around 1 GHz, and the digitization stage that follows it. Roughly half the board is analogue.

Layout is handled by a dedicated PCB engineer on the same team. Your job is to design the circuit and brief that engineer well — not to route it yourself.

Your First Six Months

We would rather tell you exactly what the work is than describe it in general terms.

Weeks 1–4

Work through the existing package: 22 schematic sheets, eight-layer Gerbers, drill data, a 55-part BOM. Rebuild the board project from the manufacturing files.

Months 1–4

Close out seven discontinued parts. The ADRF6701 is on the critical path. For each part, a verdict: drop-in,



same footprint, or block rework.

Months 4–6

Get a batch built. Brief the fabricator and the assembler, accept the boards, work through the findings.

Throughout

Compare against the reference board.
Work with the FPGA engineer on which substitutions touch the firmware.

What We Are Looking For

Board-level analogue and RF circuit design — schematics you designed, built and brought up.
Analogue: operational amplifiers, differential drivers, active and passive filters, voltage references, noise budget, energetic range.
RF: mixers, quadrature modulators and demodulators, PLL, VCO, frequency synthesizers, LNAs, attenuators, RF switches, impedance matching, S-parameters, noise figure.
Data conversion: ADC and DAC, resolution and sample rate, differential inputs, anti-aliasing filters, common-mode levels, clock jitter.
Component work: alternates, obsolescence, EOL and NRND, pin and footprint com
