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
