About this role
About the Role: We are looking for a Machine Vision Engineer who designs the imaging chain and develops the vision algorithms that run on it - from lens and lighting selection through to production software. You will combine classical machine vision with AI/ML where it adds value and deliver it as software running inside industrial equipment. Responsibilities: Optics and Imaging Design: Size the imaging chain for each inspection: field of view (FOV), working distance, spatial resolution (µm/pixel), and the measurement accuracy it must support. Select sensors and cameras - resolution, pixel size, sensor format, monochrome vs. colour, global vs. rolling shutter, area scan vs. line scan, dynamic range, and SNR. Select lenses - focal length, primary magnification, f-number and aperture, depth of field, mount type (C-mount, F-mount, TFL), telecentric vs. entocentric optics, extension tubes, and spacers. Evaluate optical performance before purchase: MTF and resolving power (lp/mm), distortion, vignetting, and chromatic aberration. Design illumination geometry - backlight, coaxial, dome, ring, bar, darkfield, and low-angle - and select wavelength, diffusion, and strobe vs. continuous operation. Apply bandpass and polarising filters, including cross-polarisation, to control glare, specular reflection, and ambient light. Set exposure, gain, and strobe timing against a motion blur budget; configure hardware, encoder, and PLC triggering with defined latency and jitter. Build optical test setups, calibration targets, and fixturing that give repeatable imaging on real parts. Camera and Acquisition Integration: Develop real-time image acquisition and vision processing pipelines. Integrate industrial cameras and camera SDKs via GenICam/GenTL and SFNC feature access. Select interfaces and size bandwidth - GigE Vision, 10 GigE, USB3 Vision, CoaXPress, Camera Link - including PoE, cabling, and frame grabbers. Manage acquisition timing, buffering, and frame or line rate against
Questions freshers ask
Is this role open to freshers?
QED BLACKBOX FACTORIES PRIVATE LIMITED hasn't stated an experience requirement for this role. Umbrix only lists roles that are fresher-eligible or leave experience unstated, so it's worth applying and letting the employer decide.
Does applying cost anything?
No. Applying is free, and it always should be. Umbrix runs every listing through a scam filter before publishing it, and any posting that asks for a registration fee, a security deposit or a training charge is rejected outright. If this employer asks you for money at any stage, that is a scam — stop and report it.
Where does this listing come from?
This posting was collected from QED BLACKBOX FACTORIES PRIVATE LIMITED's own careers listing or a licensed job feed, checked by our scam filter, and re-verified on each ingest run. The Apply button sends you to the original posting — Umbrix never sits between you and the employer.
Is this job still open?
Umbrix re-checks every listing against its source on a schedule and closes any posting that disappears. This it & software role was still live at the last check. If the employer's page says otherwise, it closed since then.
