Field System Engineer

Key Responsibilities

1. Platform Integration & On-Site Commissioning

- Lead mechanical and electrical integration of stabilized EO/IR sights onto host platforms (e.g., remote-controlled weapon stations, armoured fighting vehicles, mast mounts).

- Validate power distribution, video outputs (HD-SDI, Ethernet etc.), serial control lines (RS-422, CAN bus, MIL-STD-1553)

- Conduct platform-level checkouts and pre-trial verification before range testing

2. Optical Alignment & Boresight Calibration

- Perform high-precision multi-sensor harmonization and boresight calibration across visible (HD daylight), thermal (cooled/uncooled MWIR/LWIR), and laser channels (LRF).

- Set up optical collimators, blackbody targets, and alignment to verify Line of Sight (LOS) accuracy, parallax correction, and gimbal coordinate frames relative to weapon barrels

- Validate stabilization performance (LOS jitter, drift, tracking loop latency) under static and dynamic vehicle-motion profiles.

3. Field Trials & Firing Range Support

- Provide real-time engineering support during factory acceptance trials (FAT), field firing trials, user acceptance tests (UAT), and Environmental Stress Screening (ESS) campaigns.

- Monitor video feeds, tracking lock stability, thermal imager NUC (Non-Uniformity Correction) tables, and gimbal servo responses during weapon firing shock and high-vibration scenarios.

- Interface directly with military technical officers and test range crews to troubleshoot test anomalies and collect trial logs.

4. Troubleshooting, Maintenance & Repair

- Perform Line-Replaceable Unit (LRU) diagnostics down to sub-assembly levels (slip rings, servo motors, resolver/encoder modules, optical window assemblies, heater elements).

- Diagnose electronic board-level faults, video artifacts, communication packet drops, and thermal detector cooler degradations in ruggedized field environments.

- Carry out O-Level (Organizational) and I-Level (Intermediate) maintenance, including desiccant replacement, nitrogen purging/sealing integrity checks, and lens repolishing/cleaning per MIL-STD procedures.

5. Documentation & Training

- Deliver technical operator and maintenance training to customer technical staff and Defence operators (covering tracker tuning, reticule zeroing, and routine BIT diagnostics).

- Prepare detailed Field Service Reports (FSRs), Root Cause Failure Analysis (RCFA) reports, and trial discrepancy logs for design and QA teams.

Technical Knowledge:

- In-depth understanding of gyro stabilization (rate gyros, encoders, direct-drive BLDC/torque motors) and closed-loop motion control.

- Practical experience with thermal imaging systems, HD daylight cameras, and eye-safe Laser Rangefinders (LRFs).

- Familiarity with collimator-based testing, MTF evaluation, boresight, and optical alignment benches.

- Proficiency in communication protocols: RS-422, RS-232, Ethernet (TCP/IP, UDP), CAN bus, and video formats (SMPTE-292M / HD-SDI, analog, RTSP streaming).

- Tools & Test Equipment: Competence with digital oscilloscopes, multi-meters, serial bus analysers, optical collimators, blackbody sources, and field purging/dry nitrogen kits.
