Guidehouse is seeking a Software Developer to join our Technology / AI and Data team supporting mission-critical initiatives for Defense and Security this role you will lead the design and implementation of secure scalable ingestion and data processing workflows that power advanced AI-driven platforms. You will architect solutions for transforming complex high-volume data into structured outputs optimized for downstream AI/ML pipelines while ensuring compliance with stringent federal security and regulatory standards. Collaborating with engineers architects and mission stakeholders you will deliver innovative backend capabilities that enable accurate efficient and reliable decision-making in support of national security objectives.

What You Will Do:

• Serves as the lead backend integration engineer responsible for architecting and implementing ingestion preprocessing normalization and transformation workflows for the FBI adjudication AI platform.
• Designs ingestion frameworks supporting SF-86 forms investigative attachments summaries financial/criminal records and continuous vetting alerts using both traditional OCR and VLM/LLM-based document understanding.
• Ensures ingestion workflows comply with FedRAMP High RMF CJIS and FBI ATO requirements including logging auditability encryption and secure processing of PII and sensitive investigative information.
• Collaborates with AI/ML engineers backend API developers cloud engineers and security engineers to ensure ingestion outputs are optimized for RAG workflows SEAD-4 scoring anomaly detection and adjudicator review.

• Data Ingestion Parsing & ETL Architecture

• Design ingestion pipelines supporting LLMs and VLMs for OCR document understanding multimodal extraction and parsing of complex investigative materials including forms tables handwritten elements and embedded imagery.
• Build scalable ingestion and ETL workflows capable of processing hundreds of pages per case using OCR engines (Textract Tesseract) and VLM-based parsing models such as LayoutLM Qwen-VL Donut or LLaVA.
• Implement normalization and transformation workflows including deduplication schema harmonization field mapping classification labeling chunking segmentation and tokenization optimized for downstream LLM/RAG operations.
• Develop fault-tolerant ingestion systems with checkpointing idempotency retry frameworks ingestion-state tracking and structured error reporting.

• Backend Integration & System Connectivity

• Build secure compliant integrations with FBI systems case repositories identity/HR systems and continuous vetting alert sources using APIs ETL endpoints SFTP and message queues.
• Develop backend microservices that assemble case packages correlate evidence across disparate sources and produce structured adjudication-ready datasets.
• Integrate ingestion outputs with vector databases embedding pipelines and LLM inference services ensuring data is structured enriched and optimized for reasoning workflows.
• Ensure all integrations enforce strict authentication authorization validation and data-handling policies.
• RAG / LLM Data Preparation
• Create ingestion workflows that prepare documents and extracted content for embeddings retrieval indexing semantic search and long-context reasoning.
• Implement chunking segmentation labeling and evidence-tagging strategies designed to maximize retrieval precision and reduce hallucination risk in LLM inference.
• Develop heuristics for filtering prioritizing and contextualizing extracted information to enable fact-grounded SEAD-4 scoring and memo generation.
• Support preparation of vector representations metadata fields and retrieval keys for large-scale evidence collections.

• Security Compliance & Logging

• Implement secure ingestion pipelines aligned with FedRAMP High RMF CJIS and FBI security requirements including encryption access control PII-handling rules and secure logging.
• Apply advanced PII-safe processing techniques including automated redaction VLM-aided sensitive field detection classification tagging and compliance-driven filtering.
• Ensure ingestion systems generate detailed logs lineage metadata provenance trails and audit events supporting adjudication oversight and accreditation documentation.
• Collaborate with Security Engineers to ensure ingestion controls map to SSP requirements and POA&M items are remediated promptly.

• Performance Optimization & Reliability

• Optimize ingestion pipelines for parallelization concurrency batching memory efficiency and large-scale document processing throughput.
• Implement distributed ETL frameworks such as Step Functions Airflow Dagster Glue or Spark depending on workload and security constraints.
• Develop monitoring dashboards capturing ingestion throughput VLM/LLM OCR accuracy metrics error frequencies latency patterns and retry trends.
• Implement resilience features including dead-letter queues backoff retry mechanisms fault isolation and disaster-recovery patterns.

• Collaboration Leadership & Mission Enablement

• Align ingestion outputs directly with AI/ML engineer requirements for long-context LLM inference retrieval indexing and SEAD-4 scoring workflows.
• Work with backend API developers to ensure ingestion flows integrate seamlessly with scoring engines entity explorers memo builders and anomaly detection pipelines.
• Participate in sprint ceremonies architecture reviews backlog refinement and cross-functional coordination with mission stakeholders.
• Mentor mid-level engineers in ETL design multimodal OCR techniques distributed system patterns and secure ingestion best practices.
