Your research topic: short description  *
Example: I work on programmable photonic quantum circuits on silicon, especially large Mach–Zehnder interferometer meshes for linear-optical computing. I co-design the optical layer (waveguides, phase shifters, monitor taps) with electronics and packaging to reduce loss, reflections, and thermal crosstalk. I build closed-loop calibration routines—pilot-tone dithering and Bayesian phase retrieval—to reach a target unitary and keep it there. In the lab I measure phase noise, insertion loss, and drift with on-chip photodiodes and homodyne setups to map stability limits. For control I use FPGA or microcontroller drivers, plus PID/Kalman loops, to run heater arrays and modulators in real time. Recent work kept a 64×64 mesh stable for hours at >0.98 fidelity; the goal is a reproducible control stack that scales beyond 256 modes.

Your technical skills: short description  *
Example: I tape out with silicon-photonics PDKs (IMEC/AMF), doing layout in KLayout/Nazca and designing test structures for heaters and interferometers. I handle packaging and alignment—fiber arrays, edge or grating coupling, wafer probing, wire-bonding, and temperature control. I run automated measurements with tunable lasers, optical spectrum analyzers, and balanced photodiodes, scripted in Python (PyVISA/serial). For modeling I use FDTD/FEM tools (Lumerical, Meep, COMSOL) and circuit-level simulators or custom Python to capture mesh and thermal dynamics. I implement calibration and self-configuration algorithms in Python/C++, and integrate them with FPGA or microcontroller drivers.

Open to non-technical roles?
Many people with a technical background want to transition to non-technical roles but still within the science & tech sector. Some roles include: Product Manager, Tech Project Manager, Technical Writer & Science Communicator, Tech Sales, VC Fund Advisor. If this is your case, write down which non-technical role you are looking for. Otherwise, write None.
If any, please indicate your preferred opportunity.
If you discovered an interesting opportunity on our communication channels (newsletter, whatsapp, LinkedIn), you can mention it below with [ROLE] @ [COMPANY].
