Guidehouse is seeking a Software Developer to join our Technology / AI and Data team, supporting mission-critical initiatives for Defense and Security clients. In 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.

What You Will Need *: *

• An ACTIVE and MAINTAINED "TOP SECRET" Federal or DoD security clearance

• Requires a University Degree and minimum 4-6 years of prior relevant experience; (Relevant experience may be substituted for formal education or advanced degree)

• 5 years of backend/integration engineering experience, including 3 years in large-scale ETL or ingestion workflows.

• Deep experience with Python, Java, or Scala; ingestion frameworks such as Airflow, Step Functions, Dagster, or Glue.

• Experience with ETL pipelines, large-scale document ingestion, OCR/VLM document understanding, unstructured data parsing.

• Experience developing secure data processing/normalization workflows.

• Experience with distributed processing frameworks.

What Would Be Nice To Have *: *

• An ACTIVE and MAINTAINED "TOP SECRET" Federal or DoD security clearance.- Once onboard with Guidehouse, new hire MUST be able to OBTAIN and MAINTAIN a Federalor DoD "TOP SECRET/SCI (TS/SCI)" security clearance.

• 8+ years of backend/integration engineering experience, including 4+ years in large-scale ETL or ingestion workflows.

• Experience integrating FBI, DCSA, or NBIB systems or adjudication-related data sources.

• Experience designing ingestion workflows for RAG, embeddings, vector databases, or long-context LLM pipelines.

• Experience training or applying VLMs such as LayoutLM, Donut, Qwen-VL, or LLaVA for OCR replacement or enhancement.

• Experience with knowledge graphs, entity resolution, evidence-linking workflow development.

• Familiarity with SEAD-4, continuous vetting, or investigative case analysis processes.

• Airflow vs. Dagster vs. Step Functions.

• Textract, Tesseract, LayoutLM, Donut, Qwen-VL, LLaVA.

• Specific AWS ingestion tools (Glue, Batch, S3 eventing).
