Mixed-Signal Hardware Engineer

EMTensor GmbH; Wien; Vor Ort; EUR 16.000 - 25.000; Vollzeit

Zusammenfassung

EMTensor GmbH in Bengaluru is seeking a seasoned Analog RF Design Engineer to own mixed-signal circuit design for high-frequency front ends and data conversion stages. You will collaborate with a dedicated PCB engineer and guide layout decisions to meet impedance and EMC requirements.

The role emphasizes board bring-up on real hardware, parts lifecycle management, and coordination with firmware teams. This is a hands-on, end-to-end design position within a small team.

Qualifikationen

• Board-level analogue and RF circuit design experience.
• Schematics you designed, built and brought up.
• Experience with ADC/DAC data conversion.
• Impedance matching, LNAs, mixers and RF switches familiarity.
• Proficient with Altium Designer for PCB design.
• Ability to collaborate with FPGA/firmware teams.

Aufgaben

• Own analogue and RF circuit design for mixed-signal boards.
• Brief PCB engineer on layouts and manufacturing considerations.
• Collaborate with firmware engineers on substitutions and timing.
• Manage BOM, parts lifecycle, obsolescence and sourcing.
• Board bring-up and debugging on real hardware.

Jobbeschreibung

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.

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, dynamic 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 compatibility, second source, lead times. This is the bulk of the first few months.

Altium Designer (Allegro, OrCAD, KiCad or PADS also considered).

Board bring-up and debug on real hardware - you have seen a live board, not only CAD.

Measurement: oscilloscope, spectrum analyzer, vector network analyzer, signal generator.

Manufacturing and documentation: Gerbers, BOM, DFM, board acceptance, design documentation, change control.

An understanding of what layout needs from you: stack-up, controlled impedance, differential pairs, return current, EMC.

Based in Bengaluru. This role is on site; we are not relocating for it.

Nice to Have

A background in radar, instrumentation or scientific equipment.

SPICE or LTspice simulation.

Experience rebuilding or re-issuing an existing design rather than starting from a blank sheet.

A Note on Scope

This is board-level design, not IC design. In India the title "Analog Design Engineer" often means work inside the chip - Virtuoso, tape outs, process nodes. That is a different profession and not what this role is. PCB layout is a separate position on the same team, which we are hiring for in parallel.

This Role May Not Suit You If

Your experience is digital logic only, with no analogue or RF.

Your design work has been academic, or limited to evaluation boards.

Your recent work is repair and commissioning rather than design.

We read every application ourselves and reply to each one. If your CV lists tools without projects, add a few lines about one board you worked on - that is what we look at first.
