Sr. Full-Stack Engineer

About the RoleHOT JOB - IMMEDIATE OPENING!!!

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.

What You’ll Do in Your New Role 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, confidence indicators, 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.

Required Qualifications 7+ years of professional full-stack software engineering experience, including delivery of complex, data-intensive applications.

Demonstrated experience supporting one or more phases of the intelligence targeting lifecycle, joint targeting process, fires planning, deliberate or dynamic targeting, operational planning, intelligence analysis, command-and-control (C2), or decision-support systems within a Combatant Command, Service Component, Intelligence Community, or DoD operational environment.

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…
