IC Electronic & Telecom Systems Engineer

Fixed-term R&D; project contract (12 - 24 months, with possibility of extension)

Full-time – 40 h/week

About the project

TARRANIX is a cutting-edge R&D; initiative focused on developing next-generation photonic integrated circuits (PICs) for sustainable photonic computing. The project combines nanofabrication, photonic design, computing and photonics within a multidisciplinary team of physicists, engineers, and material scientists.

Role Overview

We are building the electronic layer that interfaces with the Tarranix fully photonic ALU. Your mission is to design the mixed-signal, reconfigurable, and embedded systems that drive on-chip lasers/modulators and read out multi-state optical logic. You will create the ELECTRONIC validation SoC: a small RISC-V–based calculator-style platform that tests and demonstrates our optical gates.

This role bridges telecom-grade optoelectronics, IC design, mixed-signal engineering, and FPGA-based control—a core position in shaping the first hybrid photonic processor.

KEY RESPONSIBILITIES





Design the electronic–photonic interface layer (laser/SOA drivers, modulator drivers, TIAs, ADCs, comparators).

Develop E/O and O/E transduction for 1550 nm systems.

Build FPGA-based control logic for modulation, timing, and multi-level photonic readout.

Integrate an ELECTRONIC RISC-V SoC (peripherals, memory-mapped photonic ALU interface, firmware).

Design mixed-signal PCBs / IC blocks ensuring clean analog + high-speed behavior.

Prototype the optical calculator demonstrator (keyboard, display, firmware).

Collaborate with photonics, metasurface, and nanofab teams to co-design the integral architecture.

WHAT SUCCESS LOOKS LIKE

A working electronics wrapper enabling full optical ALU execution.

A functional electronic RISC-V calculator demonstrator powered internally by photonic logic.

Stable, repeatable E/O + O/E transduction supporting Tarranix multi-state gates.
