10+ years of relevant experience Education Level: BS Degree - experience may be considered in place of education requirement. Briefly Describe the Work: GITI is seeking a Principal Software Engineer to support Cyber Operations Research and Development as the technical lead for production software development on a passive RF emitter identification and network analysis from real-time sensor data streams. The candidate will own the architecture, implementation, and delivery of the production pipeline - a stream ingestion, rollup, and post-processing system that operates on NDF (Network Description File) data produced by TDMA network sensors in dense, contested RF environments.

The candidate will lead a small team of senior software engineers, coordinate closely with the program technical lead and AI/ML researchers to drive Cyber Operations software from prototype to production-quality, resource-efficient components deployable on tactical edge hardware. This is a hands-on technical leadership role: the Principal Engineer writes code, makes architecture decisions, and is accountable for pipeline performance and reliability in support of real world cyber operations.

Responsibilities:
* Own the architecture and implementation of the production software pipeline, including stream ingestion, rollup, database write, and batch post-processing components

* Lead a team of Senior Software Engineers in support of real world cyber operations; assign work, conduct code reviews, enforce quality standards, and provide technical mentorship

* Establish and maintain disciplined software engineering practices: versioning, CI/CD pipelines, unit and integration testing, and documentation standards

* Design and evaluate database and storage architecture for the tactical system and research enclave environments

* Collaborate with the program technical lead to translate research findings and batch optimization algorithms into production pipeline components

* Evaluate and benchmark Python pipeline performance on tactical-box-spec hardware; identify bottlenecks and lead porting of mature components to Rust or C for edge deployment

* Manage and coordinate the tactical system VM environment and stream simulation infrastructure; ensure research VM is not disrupted by development activity

* Define and enforce stream interface contracts between the ingestion layer, database, and downstream consumers

* Evaluate emerging technologies (e.g., DuckDB/Parquet, Polars, message queues) against program requirements and recommend adoption decisions to the technical lead

* Maintain the program's Git Lab repository structure, branching strategy, and release management

* Produce clear technical documentation including architecture decision records, interface specifications, and deployment guides

* Support technical reviews and provide written inputs for sponsor deliverables as directed by the program technical lead Expert-level career professional with broad and deep application of software engineering principles across the full development lifecycle. Exercises independent judgment in evaluating methods, techniques, and approaches; identifies and resolves complex technical problems with significant program impact. Provides technical leadership and direction to other engineers.

Bachelor's (or equivalent) with 10+ years of experience.

Required Skills:

* Demonstrated experience leading a software engineering team on a production data pipeline or streaming system; ability to set technical direction and mentor junior engineers

* Expert-level Python development, including stream processing, multi-threaded/async architectures, and performance profiling

* Proficiency in one or more compiled or systems languages (Rust, C, C++, or Go) for performance-critical components; experience porting Python to compiled targets

* Hands-on experience designing and implementing relational database schemas and write-intensive data pipelines (MySQL, Postgre

SQL, or equivalent)

* Experience parsing binary serialization formats such as Flat Buffers or Protocol Buffers in a production context

* Demonstrated ability to benchmark and optimize pipeline throughput on resource-constrained hardware or cloud environment

* Strong proficiency with Linux system administration, remote server management via SSH, and air-gapped development environments

* Experience architecting multi-consumer data systems where a single write path must serve concurrent display, analytics, and batch processing readers

* Proficient in disciplined software engineering practices:
Git Lab/Git, CI/CD pipeline design, test-driven development, and code review

* Excellent written and oral communication skills; ability to produce architecture decision records and technical documentation for both engineering and leadership audiences Desired

Skills:

* Experience with TNS (Target Network System) sensor data…
