Salary: $125,000 - 175,000 per year Requirements:

• At least 7 years of professional full-stack software engineering experience, including delivery of complex, data-intensive applications.
• Experience supporting at least one phase of the intelligence targeting lifecycle, joint targeting process, fires planning, deliberate or dynamic targeting, operational planning, intelligence analysis, command-and-control, or decision-support systems in 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 developing workflow, mission-planning, decision-support, command-and-control, or operational intelligence applications.
• Ability to turn 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.
• Ability to work with operational users and deliver incrementally through regular demonstrations and feedback.
• Understanding of human-centered design for high-consequence workflows where recommendations must be transparent, reviewable, and reversible.
• Strong written and verbal communication skills, including the ability to explain technical decisions to operational and Government stakeholders.
• Eligibility for TS/SCI; an active clearance is strongly preferred.
• Ability to support on-site engagement with USPACOM J32 operators as mission needs require.
• Must be located in the NCR and able to commute to the Mark Center.
• Desired: Experience with joint targeting, Joint Fires, weaponeering, target-effect pairing, force assignment, or course-of-action analysis.
• Desired: Experience in DoD classified environments, disconnected or restricted networks, and security-compliance-driven settings.
• Desired: Experience integrating with Maven Smart System, operational data repositories, simulation engines, or government interfaces of record.
• Desired: Experience developing optimization or recommendation systems that present alternatives, constraints, and explainable rationale.
• Desired: Experience supporting independent testing and evaluation, operational acceptance testing, and deployment into government production environments.

• Design, develop, integrate, and field secure software for USPACOM J32 joint targeting and fires-planning workflows.
• Build operator-facing Target-Effect Pairing applications with ranked recommendations, alternative pairings, constraint-based tradeoffs, and explanations.
• Develop backend services for workflow orchestration, recommendation processing, review and adjudication, approval routing, deconfliction, and draft force-assignment support.
• Translate Joint Fires and Targeting subject matter expert input into intuitive workflows for Phase 3 Capabilities Analysis and Phase 4 Commanders Decision and Force Assignment.
• Implement human-machine teaming controls that let authorized users accept, reject, modify, and route recommendations while preserving human authority over inherently governmental decisions.
• Create traceable, 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, object-management systems, simulation services, and command-and-control interfaces, using secure APIs and event-driven patterns.
• Build interfaces that communicate inventory constraints, timing and availability limitations, assumptions, confidence indicators, infeasible conditions, and recommended next steps.
• Develop resilient services for single-target, multi-target, and constrained-resource planning in connected and degraded operating conditions.
• Implement role- and attribute-based access controls, classification-aware data handling, secure service communication, and tamper-evident auditing.
• Create automated unit, integration, regression, performance, and security tests suitable for Government acceptance and independent testing and evaluation.
• Collaborate with J32 operators, Joint Fires and Targeting experts, weaponeering experts, data engineers, security teams, and Government system owners.
• Participate in sprint planning, backlog refinement, operator demonstrations, technical reviews, and fielding in Government-designated environments.
• Produce maintainable code, API documentation, architecture decision records, release notes, runbooks, and transition materials for Government operation and sustainment.
