Sr. Full-Stack Engineer (USPACOM)

Culmen International LLC • Alexandria, VA

3d • Onsite

About The Position

Culmen International is seeking a Senior Full-Stack Engineer to support secure, mission-ready software development for USPACOM J32 targeting and mission-planning workflows. Must be located in the NCR and able to commute onsite to the Mark Center. As the Senior Full-Stack Engineer, you will design, develop, integrate, and field secure software applications that support targeting and mission-planning operations. You will build user-facing and backend services, develop system integrations, implement auditability and security controls, and collaborate directly with operators and subject matter experts to translate complex operational processes into intuitive, mission-focused software solutions. This role requires full software development lifecycle expertise, including requirements analysis, architecture, testing, deployment, and sustainment in classified environments.

Requirements

• 7+ years of professional full-stack software engineering experience, including delivery of complex, data-intensive applications.
• Strong experience with modern front-end frameworks, backend services, RESTful APIs, event-driven architectures, relational or document databases, and automated testing.
• Experience building workflow, mission-planning, decision-support, command-and-control, or operational intelligence applications.
• Ability to transform complex operational and doctrinal processes into usable, explainable software.
• Experience with data provenance, audit logging, workflow state management, access controls, and configuration or model versioning.
• Familiarity with containerized deployments, CI/CD pipelines, infrastructure-as-code, observability, and secure cloud or on-premises environments.
• Demonstrated ability to collaborate with operational users and deliver incrementally through frequent demonstrations and feedback.
• Understanding of human-centered design for high-consequence workflows where recommendations must remain transparent, reviewable, and reversible.
• Excellent written and verbal communication skills, including the ability to explain technical decisions to operational and Government stakeholders.
• Eligibility for TS/SCI; active clearance strongly preferred.
• Ability to support on-site engagement with USPACOM J32 operators as mission needs require.

Nice To Haves

• Experience with joint targeting, Joint Fires, weaponeering, target-effect pairing, force assignment, or course-of-action analysis.
• Experience working in DoD classified environments, disconnected or restricted networks, and security-compliance-driven settings.
• Experience integrating with Maven Smart System, operational data repositories, simulation engines, or government interfaces of record.
• Experience developing optimization or recommendation systems that present alternatives, constraints, and explainable rationale.
• Experience supporting independent T&E, operational acceptance testing, and deployment of software into government production environments.

Responsibilities

• Design, build, and field secure, mission-ready software supporting USPACOM J32 joint targeting and fires-planning workflows.
• Develop operator-facing applications for Target-Effect Pairing (TEP), including ranked recommendations, alternative pairings, constraint-driven tradeoffs, and explanations.
• Build backend services for workflow orchestration, recommendation processing, review and adjudication, approval routing, deconfliction, and draft force-assignment support.
• Translate Joint Fires and Targeting SME input into intuitive workflows supporting Phase 3 Capabilities Analysis and Phase 4 Commander’s Decision and Force Assignment.
• Implement human-machine teaming controls that allow authorized users to accept, reject, modify, and route recommendations while preserving human authority over inherently governmental decisions.
• Create traceable and auditable software that records source data, model or ruleset versions, recommendation history, user actions, timestamps, and approval rationale.
• Integrate with Government-designated systems—including Maven Smart System (MSS), object-management systems, simulation services, and command-and-control interfaces—through secure APIs and event-driven patterns.
• Build interfaces that clearly communicate inventory constraints, timing and availability limitations, assumptions, infeasible conditions, and recommended next steps.
• Develop resilient services capable of supporting single-target, multi-target, and constrained-resource planning scenarios in connected and degraded operating conditions.
• Implement role-based and attribute-based access controls, classification-aware data handling, secure service communication, and tamper-evident audit capabilities.
• Create automated unit, integration, regression, performance, and security tests suitable for Government acceptance and independent test and evaluation.
• Partner directly with J32 operators, Joint Fires and Targeting SMEs, weaponeering experts, data engineers, security teams, and Government system owners.
• Participate in sprint planning, backlog refinement, operator demonstrations, technical reviews, and fielding activities in Government-designated environments.
• Produce maintainable code, API documentation, architecture decision records, release notes, runbooks, and transition materials supporting Government operation and sustainment.

Benefits

• Exceptional Medical/Dental/Vision Insurance, premiums for employees are 100% paid by Culmen, and dependent coverage is available at a nominal rate (including same or opposite sex domestic partners)
• 401k – Vested immediately and 4% match
• Life insurance and disability paid by the company
