Senior Integration and MBSE Engineer

LMI is seeking a Senior Systems Engineer to serve as the design-to-implementation lead for system interfaces, pipeline engineering design, and detailed systems engineering specifications within the F-35 LogIT program. This role works from the architecture baseline and extends it into detailed technical designs for data ingestion, transformation, transport, validation, metadata, observability, and security controls across government and OEM integration points. The role is engineering-oriented and requires a senior contributor who can shape design decisions, contribute to model-based engineering, and provide detailed systems engineering depth across ERP, DLMS, and government integration activities. LMI is a new breed of digital solutions provider dedicated to accelerating government impact with innovation and speed. Investing in technology and prototypes ahead of need, LMI brings commercial-grade platforms and mission-ready AI to federal agencies at commercial speed. Leveraging our mission-ready technology and solutions, proven expertise in federal deployment, and strategic relationships, we enhance outcomes for the government, efficiently and effectively. With a focus on agility and collaboration, LMI serves the defense, space, healthcare, and energy sectors-helping agencies navigate complexity and outpace change. Responsibilities

• Translate enterprise architecture and Cameo model baselines into detailed systems engineering designs for interfaces, message flows, adapters, pipeline segments, validation services, and data routing logic.
• Develop and maintain detailed Cameo SysML models that capture system interfaces, activity flows, message exchanges, traceability relationships, and allocation of functions across the integration fabric.
• Define detailed technical designs for ingestion from structured, semi-structured, and unstructured sources, including OEM systems, APIs, file drops, message queues, databases, and transferred vendor systems.
• Design data transformation logic for field-level enrichment, identifier crosswalks, unit normalization, DLMS and MILSTRIP translation, and conversion into modern schemas such as JSON and Parquet.
• Produce detailed interface and integration designs for DAAS, ELMS/DPAS, DLA EBS/IDE, ILS-S, ESCAPE, Navy ERP, USTRANSCOM IGC, JPO systems, and Advana-aligned data pipelines.
• Define system-level requirements and design patterns for transport, publish/subscribe messaging, point-to-point exchange, retries, buffering, quarantine logic, and ordered delivery where required by mission criticality.
• Support detailed designs for metadata capture, schema validation, lineage, anomaly detection, and audit-grade provenance throughout the data lifecycle.
• Engineer secure systems design patterns for data in transit and at rest, authentication, authorization, redaction, tagging, and Cross Domain Solution handling across classified and unclassified environments.
• Work directly with development, data engineering, and platform teams to refine user stories, resolve design gaps, and ensure that implementation stays aligned with architecture and systems engineering intent.
• Contribute to sprint reviews, integration planning, technical exchange meetings, and validation activities by explaining detailed technical behavior to both engineers and government stakeholders.

• Bachelor's degree in systems engineering, software engineering, computer science, information systems, electrical engineering, or a related technical field.
• 8 or more years of relevant experience in systems engineering, solution engineering, data integration engineering, or enterprise application engineering in federal, defense, ERP, or logistics environments.
• Demonstrated experience with model-based systems engineering using Cameo Systems Modeler / MagicDraw and SysML to capture system behavior, interfaces, activities, allocations, and traceability.
• Experience contributing to defense architecture artifacts such as OV-1, SV-1, and OV-5b or equivalent views, especially where those views must remain synchronized with implementation design.
• Strong experience designing integration solutions across ERP, logistics, and data platforms, including APIs, EDI/DLMS, databases, event streams, file-based exchange, and hybrid cloud/on-prem connectivity.
• Practical experience with interface and pipeline design using technologies such as Kafka, NiFi, Airflow, Python, Spark, SQL, REST, GraphQL, SOAP, JDBC/ODBC, MQ, and related integration mechanisms.
• Strong understanding of Defense Logistics Management Standards, MILSTRIP/MILSTRAP-style transactions, field mapping, schema validation, and translation to modern data structures.
• Understanding of government logistics and sustainment systems and the roles they play in requisitioning, asset visibility, cataloging, transportation, maintenance, repair, and financial accountability.
• Familiarity with DoD cybersecurity and deployment considerations, including IL designations, PKI, CAC/PIV, STIGs, RMF, audit logging, and secure movement of data across boundaries.
• Active SECRET clearance or the ability to obtain and maintain one., * Experience with F-35 data, sustainment workflows, or aviation logistics integration environments.
• Experience integrating or designing for systems such as DAAS, ELMS, DLA EBS/IDE, ILS-S, Navy ERP, ESCAPE, IGC, JPO systems, or Advana-aligned pipelines.
• Familiarity with SAP-centric logistics and financial workflows in environments where ERP transactions must be reconciled with external logistics or sustainment events.
• Experience with observability and telemetry patterns using Grafana, Prometheus, ELK, Splunk, or comparable stacks.
• Experience operating in agile delivery organizations that use Jira, GitLab, and quarterly PI Planning.
