Optical & Imaging Systems Engineering
Analyse and interpret the performance of electro-optical imaging systems at instrument and mission level.
Investigate imaging-system behaviour across optical, detector, electronic, firmware, thermal, mechanical, calibration, and operational domains.
Interpret imaging performance characteristics including MTF/OTF, spatial resolution, SNR, radiometric performance, detector response, spectral response, focus, distortion, and field-dependent performance.
Analyse engineering, calibration, and test data to determine whether measured behaviour is consistent with expected system performance.
Understand the relationships between optical design, detector characteristics, thermal environment, mechanical alignment, calibration, and operational configuration.
Interpret and critically assess optical performance models, verification results, and measured payload performance.
Translate instrument-level performance into practical implications for spacecraft integration, mission operation, and image-product performance.
Support the investigation and resolution of anomalous or unexpected imaging-system behaviour.
System-Level Problem Solving
Understand the optical payload as an integrated system, recognising interactions between optical, detector, electronic, firmware, mechanical, thermal, calibration, operational, and customer spacecraft domains.
Diagnose complex performance and operational issues across system and subsystem boundaries.
Develop structured technical investigations based on available evidence, engineering analysis, and targeted testing.
Clearly distinguish between observed facts, engineering interpretation, working hypotheses, and conclusions supported by evidence.
Identify the additional evidence, testing, or specialist analysis required to progress an investigation.
Interpret technical and performance data and translate it into actionable engineering insight.
Develop a strong understanding of how Simera Sense products behave within real customer spacecraft and mission environments.
Technical Investigation & Escalation
Independently own complex or high-impact technical investigations from initial problem definition through analysis, recommendation, and closure.
Establish clear investigation structures covering known facts, open questions, engineering hypotheses, required evidence, risks, and next actions.
Determine when specialist Optical, Electronics, Firmware, Mechanical, Systems, Production, or Product Engineering input is required.
Coordinate specialist engineering inputs while retaining ownership of the overall technical investigation and customer-facing technical narrative.
Escalate appropriately when required, providing clear problem definition, supporting evidence, analysis, and specific technical questions.
Take technical leadership during complex customer investigations and drive activities towards a defensible conclusion or clearly defined next step.
Cross-Functional Collaboration
Work closely with Optical, Systems, Mechanical, Electronics, Firmware, Production, AIT, Product, and Commercial teams to investigate and resolve customer technical issues.
