## Job description

Position Title: Principal Software Engineer Location: Remote with travel to customer sites Clearance Requirement: Top Secret/SCI required Employment Type: Full-Time Research Innovations, Inc. (RII) is breaking through the big, slow, status quo with transformative technology that fundamentally changes and improves the world. We develop cutting-edge software for all levels of the government and military. Using agile development practices and user-centered design, we create innovative software solutions for complex real-world problems. We are looking for a committed Principal Software Engineer to join the MAX Electromagnetic Warfare (EW) product team within our Tactical Command & Control line of business. You will help build the EW and spectrum operations capabilities of the MAX platform — modeling complex electromagnetic environments, integrating physics-based propagation models, and turning messy real-world data into workflows warfighters actually use. Get s#it done. This position requires an active US Top Secret/SCI clearance.

## WHAT YOU WILL BE DOING

- Design and develop EW and electromagnetic spectrum operations capabilities for the MAX platform, from data model to user-facing workflow

- Model complex operational domains in code: design schemas and data models that unify disparate, messy data sources into coherent, trustworthy representations

- Integrate and validate physics-based RF propagation models, terrain and clutter data, and third-party services via APIs

- Build and maintain integrations with external C2 systems, sensor feeds, and telemetry sources

- Develop with modern AI-assisted and agentic coding workflows: shape the problem, author and review detailed implementation plans, direct AI coding agents, and own the quality and correctness of what ships

- Collaborate through plan reviews and merge requests in a highly collaborative, no-egos team culture

- Demo working software to customers, translate their feedback into priorities, and iterate quickly

- Support deployment of the product across cloud, on-premises, and edge/DDIL environments

- Contribute to software design and test documentation, and mentor teammates in your areas of depth

- Continuously challenge yourself to become a better software developer

## WHAT YOU HAVE DONE

- BS degree in a related technical field and 5+ years of relevant professional experience (an advanced technical degree may substitute for a portion of the experience)

- Modeled complex real-world domains in software: schema and data model design, entity resolution across disparate sources, and API-based data integration

- Professional experience in Python, C#, Java, or similar languages, and with SQL-based persistence solutions

- Experience integrating data from third-party applications and services via REST APIs

- Hands-on experience with AI-assisted or agentic software development, including reviewing and verifying AI-generated work

- Disciplined testing practices: unit testing, test-driven development, and validation of your own work

- Experience working in containers (Docker) and familiarity with Kubernetes-based deployment

- Experience demoing software to customers and translating user needs into technical requirements

- Ability to multitask, self-assign work, and function in a dynamic, fast-paced development environment

-

## Experience mentoring other developers

- Excellent verbal and written skills

## EVEN BETTER

- Experience with electromagnetic spectrum operations: spectrum management, RF propagation modeling, link analysis, or EW planning workflows

- Experience supporting DoD customers, including on-site engagement with program offices or operational units

- Familiarity with terrain, elevation, and land cover data sources (DTED, GMTED, LiDAR-derived datasets)

- Experience with data across classification levels, cross-domain solutions, and build-low/ship-high development

- Experience with Tactical Assault Kit (TAK) or integrating with platforms such as Palantir via OSDK/APIs

-

## Experience with edge and DDIL deployment environments
