Jobs at Firefly Aerospace

Own turbopump hardware across its lifecycle, from requirements and fluid/mechanical design through analysis, manufacturing, testing, qualification, and flight operations. Lead turbomachinery design improvements, first-principles modeling, tolerance analysis, test planning, data review, anomaly resolution, and system-level trade studies. Support assembly, quality, non-conformance disposition, engine testing, stage testing, and launch operations while serving as the Alpha engine turbomachinery subject matter expert.

Designs, develops, tests, qualifies, and supports propulsion valves, regulators, and actuators across their full product lifecycle. Leads design reviews, qualification and acceptance testing, failure investigations, nonconformance resolution, production support, and cross-functional hardware delivery. Develops simulation-based design methods, validates hardware through testing, standardizes solutions, and improves cost, reliability, yield, and manufacturability for aerospace propulsion systems.

Designs and maintains infrastructure-as-code, CI/CD pipelines, automation, monitoring, and Linux-based systems across development, staging, and production. Troubleshoots infrastructure and deployment issues, supports engineering teams, performs root-cause analysis, responds to incidents, manages Git workflows, and implements security and compliance controls. Participates in on-call support and collaborates with IT, software engineering, systems engineering, and security teams.

Manage cybersecurity authorization and compliance for mission-critical space and enterprise systems. Lead RMF processes, ATO packages, SSPs, POA&Ms, SARs, continuous monitoring, control assessments, STIG validation, vulnerability remediation, and CMMC/NIST compliance. Translate national security requirements into system controls, support engineering reviews, coordinate with system owners and Authorizing Officials, and brief executives and government customers. The role also supports DCSA assessments, security audits, incident response, and secure system development.

Designs, builds, tests, and deploys AI-powered tools and applications supporting manufacturing and business operations. Develops quality-control and production-automation systems, MLOps and model-evaluation pipelines, data pipelines, APIs, and integrations. Partners with business and technical teams, coordinates infrastructure needs, conducts system audits, creates documentation, troubleshoots issues, and improves AI/ML capabilities within an Agile/Scrum environment.

Develop and integrate critical C++ platform software, firmware, SDK components, libraries, APIs, and onboard applications for spacecraft systems. Work with embedded Linux, sensors, cameras, hardware buses, networking, multithreaded software, and heterogeneous compute platforms. Support perception integration, simulation, hardware and software testing, spacecraft integration, mission operations, system-level debugging, architecture decisions, technical reviews, and engineering mentorship.

Leads spacecraft systems engineering across design, fabrication, testing, launch, and mission operations. Owns system architectures, requirements, interfaces, technical budgets, verification plans, design reviews, risk management, and configuration control. Resolves test failures and nonconformances while coordinating hardware, software, manufacturing, integration, and operations teams. Supports offsite testing and lunar mission operations, including extended shifts. Requires deep interdisciplinary aerospace expertise and extensive spacecraft lifecycle experience.

The Senior Hardware Design Engineer will lead circuit card development, collaborate with teams on avionics platforms, and troubleshoot designs for space applications.

The Propulsion Engineer II will design, develop, and deliver propulsion components, manage product lifecycle, and lead cross-functional teams for high-performance valve systems.

As a Spacecraft Systems Engineer II, you will develop spacecraft systems, manage technical budgets, validate architecture, and ensure operational efficiency for space missions.

As a System Configuration Engineer, you will manage vehicle-level configuration, oversee CAD integration, maintain traceability, and coordinate with design and manufacturing teams.

Design, develop, test, and qualify high-performance valves, regulators, and fluid components across the product lifecycle. Lead reviews, author and run qualification/acceptance tests, support production, standardize solutions, drive cost and risk reductions, perform simulations and failure investigations, and coordinate cross-functional teams to deliver hardware on schedule.

Provide technical leadership and ownership of spacecraft and launch vehicle electrical and avionics architectures. Define requirements, oversee design, integration, verification, and qualification of power, C&DH, comms, harnessing, FPGA/firmware, and PCB hardware. Lead reviews, trade studies, risk assessments, test strategies, anomaly resolution, and mentor engineering teams while driving reusable modular architectures and technology roadmap.

Design, develop, test and integrate embedded flight software for spacecraft. Collaborate with engineers, optimize firmware for performance and conduct code reviews.

Design, develop, test, and integrate embedded flight firmware for microcontrollers and processors in bare-metal or RTOS environments. Implement low-level drivers and communication protocols, collaborate with hardware teams to debug integrations, optimize for power/performance, participate in code reviews, and validate system-level performance. Optionally support FPGA integration and custom OS builds.

As a Spacecraft Systems Engineer, you will oversee the development of spacecraft, manage requirements and interfaces, and ensure successful mission execution through design reviews and test planning.

Design, analyze, test, and operate in-space propulsion hardware (main and attitude engines, valves, tanks). Lead development, qualification, and acceptance testing, create manufacturing and integration processes, perform flight operations, identify risks and trade studies, and develop automation and test data analysis tools while collaborating across disciplines.

Lead design, analysis, development, and qualification of payload segments and mechanical spacecraft interfaces. Produce CAD, drawings, perform FEA and hand calculations, define tests to industry standards, support builds/integration, and mentor junior engineers while collaborating with cross-functional teams and customers.

Lead design, analysis, test, and qualification of spacecraft fluid and propulsion subsystems from concept through flight. Own requirements, CAD/analysis, hardware development, integration, and test; coordinate manufacturing and operations; perform trade studies, risk identification, and data-driven decisions; develop automation and test-analysis tools; support flight and launch campaigns and troubleshoot fluid system operations.

Perform structural analysis for spacecraft, launch vehicles, and ground support using hand calculations and FEA (ANSYS, NX Nastran). Develop test requirements, validate models with test data, review analyses, define material properties and part changes, and write strength and stability margins to meet program safety factors.
