Role Description 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. 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 GitLab 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. Qualifications - 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. Requirements - 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, PostgreSQL, or equivalent). - Experience parsing binary serialization formats such as FlatBuffers 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: GitLab/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 formats and NDF ICD specifications. - Familiarity with TDMA network protocols, time-division access architectures, and passive RF signal processing concepts. - Experience deploying and operating software on tactical edge hardware co-located with a sensor system. - Experience with lightweight stream or message queue architectures (ZeroMQ, RabbitMQ, or equivalent). - Experience with Polars or DuckDB for high-performance analytical workloads and write-once/read-many storage patterns. - Experience with LLM-assisted software development tools (e.g., Claude Code, GitHub Copilot, JetBrains AI Assistant, or equivalent); demonstrated ability to use AI tools productively for code generation, refactoring, and test case development while maintaining engineering judgment and code quality standards. - Familiarity with AI/ML model inference integration — ability to incorporate batch optimizer outputs into the production pipeline without requiring ML expertise. - Experience with browser-based data visualization or reporting tools (React, D3, or equivalent) as a consumer of pipeline output. - Experience with Jupyter Notebooks and research enclave environments; ability to bridge from research prototype to production code. - Experience with FlatBuffers binary stream replay and simulation infrastructure for pipeline testing. - Familiarity with Rust toolchain and ecosystem for systems-level development on Linux. Relevant Certifications - Certifications in software engineering, computer science, or related fields (e.g., Certified Software Development Professional (CSDP); Certified Secure Software Lifecycle Professional (CSSLP); Red Hat Certified Engineer (RHCE); C++ Certified Professional Programmer (CPP); Professional Software Developer Certification (PSD); etc.).

• As a Senior PLC Engineer, you'll own the controls software that keeps our infrastructure online. • This is a hands-on build role. • You'll take an architecture from concept to commissioned, running system, programming the PLCs and SCADA and writing the software, services, and tooling around them. • Design, develop, test, and commission PLC programs on Siemens (TIA Portal, S7-1500/1200) and/or Rockwell/Allen-Bradley (Studio 5000, ControlLogix/CompactLogix) platforms, using IEC 61131-3 languages (Structured Text and ladder), for cooling and mechanical plant equipment: CDUs, chillers, hydraulic skids, fan walls, DOAS, and pumps. • Develop the supervisory logic for the Master Plant Controller, including equipment staging, lead/lag, setpoint reset, failover, and plant-level coordination across multiple skids. • Build and maintain the SCADA/HMI layer (Siemens WinCC, Rockwell FactoryTalk View, or Ignition): operator screens, alarming, trending, historian, and access control. • Write robust safety logic, interlocks, and alarm strategies for pressurized and high-power equipment, and uphold a safety-first engineering standard. • Integrate OEM-controlled equipment such as chillers and DOAS over Modbus TCP, BACnet, OPC UA, EtherNet/IP, and PROFINET, defining and validating register and object maps. • Build process simulations and digital twins (Siemens PLCSIM Advanced / SIMIT, Rockwell Studio 5000 Emulate / Emulate3D, or scripted models) to validate logic and tune control loops before site deployment. • Lead field commissioning, startup, and loop checks. Troubleshoot live systems and drive issues to resolution. • Apply real software engineering practices to controls work: version control, code review, modular and reusable function-block libraries, and clear naming and documentation standards. • Build the general-purpose software around the controls stack: data pipelines, monitoring and telemetry services, edge and cloud integrations, internal tooling, and automation that connects plant data to the rest of Giga's systems. • Translate the controls engineer's architecture and sequence-of-operations into working, well-structured, maintainable code. • Operate comfortably in ambiguous, unstructured environments and solve problems where established processes don't yet exist.

• Develop and customize the internal developer portal using the SaaS platform's public APIs and webhooks. • Design, develop, and maintain microservices and RESTful/asynchronous APIs using Python (FastAPI, Django or Flask). • Implement front-end improvements using JavaScript and jQuery, ensuring an excellent user experience. • Deploy, scale, and operate applications on AWS, Azure, or GCP using Docker, Kubernetes, Serverless, and managed services. • Collaborate with DevOps teams to build and maintain CI/CD pipelines, infrastructure as code (Terraform/CloudFormation), automated testing, and deployment processes. • Monitor and optimize application performance, availability, security, and scalability. • Participate in architecture reviews and code reviews, promoting development best practices.
