The objective is to develop an AI model that detects and classifies Longitudinal and Transverse Cracking (LTC) in asphalt airfield pavements, in accordance with ASTM D5340-24. The model will use fused Digital Elevation Model (DEM) and imagery data to identify cracks, measure their extent, and assign a severity level (Low, Medium, or High) based on the standard's width and spalling criteria. The output will support the broader Pavement Condition Index (PCI) workflow used across the company's 85-model system. What you'll need to do: • Access and understand the provided DEM and imagery data, along with existing labels • Build a pipeline that fuses DEM and imagery to detect cracks and measure their length and width • Train a model to classify each detected crack as Low, Medium, or High severity per the ASTM thresholds • Apply the standard's exclusion rule so distresses are not double-counted where other cracking is already recorded • Validate the model's outputs against the team's verified ground truth and report accuracy • Deliver the trained model along with a short write-up of results and any limitations

The Role You will work directly with our hardware/firmware engineer to: Develop AI/ML models for complex physical-system data Apply physics-informed and scientific machine-learning techniques Analyze multi-channel time-series data Develop signal-processing and feature-extraction pipelines Build and evaluate anomaly and state-estimation models Develop multimodal modeling approaches Optimize models for edge/embedded deployment Integrate the intelligence layer with existing hardware and firmware Help develop the POC into a robust production architecture Ideal Background PhD strongly preferred in Machine Learning, Computer Science, Computational Physics, Electrical Engineering, Applied Mathematics, Signal Processing, or a related discipline. We are particularly interested in experience with: Physics-Informed / Scientific ML Signal Processing Time-Series ML Sensor Fusion Anomaly Detection Physical-System Modeling Embedded ML / Edge AI PyTorch / TensorFlow / JAX NumPy / SciPy C/C++ / Embedded Systems Candidates who have successfully taken ML from research into real-world physical hardware are strongly preferred. Current Stage The hardware POC and data-acquisition system are already under development. The selected candidate will work directly with our hardware/firmware engineer to develop, validate, and integrate the AI/ML layer. There is potential for a significant ongoing role for the right person. To Apply Please briefly answer: What is the most relevant scientific-ML or physical-system ML project you have personally built? What portions did you personally design and implement? What experience do you have with real-world sensor/time-series data? Have you deployed ML onto embedded or edge hardware? Please provide relevant publications, GitHub repositories, patents, or other technical work. Application details, hardware architecture, use case, datasets, system objectives, and other proprietary information will be disclosed only to selected candidates following an NDA.

I built a working website prototype with AI tools. What I am looking for is someone who works the way I want to work, several levels up: an AI engineer who can take something built this way and make it real, secure, and maintainable. To be clear about what I am not looking for. I do not want to hand a spec to a web development shop and receive a finished website. I want a partner who is fluent in building with AI, who can tell me where the AI-generated foundation under this thing is fine and where it is quietly dangerous, and who can get the intelligence at the center of the product working properly. I want to be in the room while it is built rather than handed the keys at the end. Where the project is today A self-contained single-file web application, roughly 100KB, built with AI tools, that runs in any browser with no server Around fifteen pages behind a client-side router A working assistant that answers plain-language questions and returns structured results, currently running on hand-written rules rather than a model All content lives in JavaScript arrays inside the file No hosting, no database, no backend, no authentication The assistant is the product The assistant needs to run on a live model, answer only from my data, and never invent a fact. Users will ask vague, badly-phrased questions using the wrong vocabulary, and it has to handle that without guessing. One failure mode I have already hit in testing: a query returned three correct results and silently left out four others that also qualified. Nobody watching knew what was missing. Getting that class of problem solved, and provably solved, is the core of this job. So I need someone with real opinions about retrieval and grounding, system prompt design, refusal behavior, handling ambiguous input, and how you test any of it. Specifically: how do I know the assistant is right, and how do I know a change I make next month did not break it? What I need built Everything built in my accounts and under my ownership from day one: repository, hosting, domain, database, model API keys A real stack and hosting on a custom domain, with a deployment process I can run A database as the single source of truth, with the content migrated out of the current file The assistant on a live model, server-side, with proper key handling, retrieval grounded in my data, refusal behavior when the answer is not there, rate limiting and cost controls An evaluation approach for the assistant. A test set, a way to catch regressions, and a way to measure completeness rather than just plausibility A way for non-technical contributors to add and correct content without touching code Security done properly and documented in plain language, including the AI-specific parts: API keys never reaching the client, prompt injection, what the model can and cannot see, abuse and runaway cost, plus the ordinary work of TLS, headers, secrets, backups, restores and dependency hygiene You are a good fit if you have Shipped LLM-powered products to production, not just demos Built retrieval over your own structured data, and have been burned by it Strong views on evaluating model output, and a practical method rather than a vibe Worked with non-technical founders and can explain a tradeoff without dumbing it down or burying me Fluency with the current AI build tools, and honesty about their limits In your proposal, please answer these four questions. Link one LLM-powered product you took to production. What was the architecture, and what broke in ways you didn't expect? My assistant returned three correct results and silently omitted four that also qualified. Diagnose that from what I have told you, and tell me how you would prevent the whole category, not just the instance. How do you evaluate an assistant like this? I want the actual method, including how you catch a regression after a change. What is your honest read on the fastest path: rebuild on a proper stack, or extend what exists? Tell me why. Assume I will ask follow-up questions. How this starts A paid two- to three-hour working session where you walk me through your read of the prototype and the architecture you would propose. I will share the prototype under NDA once we are talking. If this goes well there is likely ongoing work beyond the initial build.

The use case is AI-assisted prior authorization document preparation for specialty medication or imaging order. We have healthcare data in FHIR / EHR export format, including patient demographics, diagnosis codes, medications history, lab results, provider notes, previous treatments, allergies, and encounter history. The system should review this data and help generate a prior authorization support summary for clinical staff, showing why the request meets medical necessity. The workflow should be able to extract relevant clinical evidence from the chart, match it against authorization requirements, and generate structured output such as: - Patient and diagnosis summary - Requested medication / procedure - Relevant ICD/CPT/NDC codes if available - Previous failed therapies or contraindications - Supporting labs, notes, and visit history - Missing documentation or data needed before submission - Draft medical necessity summary for staff review We need someone to check our current AWS architecture and implement this workflow inside existing AWS setup. The implementation may use AWS Bedrock, SageMaker, Comprehend Medical, Lambda, S3, API Gateway, or other AWS services depending on what fits best. This work requires real healthcare software experience, not only general AI experience. HIPAA compliant design is important, including PHI handling, encryption, IAM permissions, secure data movement, CloudWatch logging, audit trail, and no unsafe storage of sensitive patient data.
