Program Development Scheduler III

Development Scheduler

As an end-to-end responsive space company, Firefly Aerospace is on a mission to enable our world to launch, land, and operate in space—anywhere, anytime. Our small- to medium-lift launch vehicles, lunar landers, and orbital vehicles service the full lifecycle of government and commercial missions from low Earth orbit to the Moon and beyond. Through carbon composite structures, patented propulsion technologies, and common vehicle architectures, Firefly delivers rapid iteration, improved reliability, and cost-efficient access to space.
This position is based at our manufacturing and test facility in Briggs, TX.
The Development Scheduler is responsible for building and managing integrated schedules that connect engineering development, qualification testing, and early production builds into a single executable plan.
This role operates at the intersection of program management and manufacturing execution, ensuring development hardware progresses through design release, fabrication, assembly, integration, and qualification in alignment with program milestones. The Development Scheduler translates program objectives into integrated, resource-loaded schedules, drives alignment between design maturity, build readiness, and test timelines, and ensures development builds are executable—not just planned.
Responsibilities include:
Develop and maintain Integrated Master Schedules (IMS) for engineering development, prototype and development builds, and qualification test campaigns
Ensure alignment between development, qualification, and production readiness gates
Build schedules that reflect actual execution constraints, resource availability, and operational priorities
Partner closely with Program Managers, Engineering Leads, Test & Validation, and Manufacturing to translate program-level objectives into executable schedules
Ensure development builds are ready for execution, including released work instructions, validated tooling, available materials, and aligned routings
Own schedule structure, dependency logic, and integrity within Microsoft Project
Apply scheduling best practices including critical path management, dependency logic, resource loading, and schedule leveling
Identify and actively manage critical path activities across development and qualification phases
Perform what-if scenario analysis to evaluate impacts from design changes, supply disruptions, and test delays
Track milestone adherence, schedule variance, and critical path health against baseline plans
Generate schedule reports for internal leadership, program reviews, and customer visibility as required
Maintain short-interval execution schedules tied to shop floor activity
Capture lessons learned from development execution and support transition into stable production environments
Drive cross-functional alignment to improve schedule credibility and execution success across programs
Required qualifications include:
5+ years of experience in development scheduling, program scheduling, or engineering/manufacturing program environments
Expert-level proficiency in Microsoft Project
Strong experience with complex dependency logic, resource loading and leveling, critical path analysis, and scenario modeling
Strong understanding of Integrated Master Scheduling (IMS) principles
Experience supporting development and qualification lifecycle
