Senior Stealth Mode Startup Jobs (NOW HIRING)

Job Summary:
Stealth is a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. They are seeking a Fire Control Systems Software Engineer to design, build, integrate, and validate software for missile defense systems, ensuring safe execution of weapon employment and coordination of launcher actions.
Responsibilities:
• Architect, implement, and test fire control and engagement management software that bridges sensors and C2 systems to launchers, interceptors, or other effectors.
• Develop core functionality such as track ingestion, target state handling, engagement state machines, weapon-target pairing, launcher/effector command sequencing, inhibit/arm/fire logic, and post-launch status management.
• Design software interfaces and message flows across radar/sensor systems, C2 nodes, launchers, effectors, simulators, and operator-facing mission software.
• Build deterministic, fault-tolerant behavior under tight timing and reliability constraints, including degraded modes, interlocks, watchdogs, and safe-state transitions.
• Translate mission and system-level requirements into clear software behavior, interface definitions, and testable acceptance criteria.
• Partner closely with systems engineering, hardware, integration/test, simulation, GNC, and product teams to deliver end-to-end capability.
• Contribute to verification and validation through SIL/HIL/HWIL environments, Monte Carlo analysis, integration labs, ground test, and live or operational test events.
• Participate in requirements reviews, design reviews, hazard analyses, FMEAs, test readiness reviews, and customer technical interchange meetings.
• Help establish engineering best practices for safety-critical and customer-facing defense software, including traceability, release discipline, field issue triage, and root-cause analysis.
• Mentor other engineers and elevate the team’s understanding of fire control architectures, government program rigor, and mission-driven development.
Qualifications:
Required:
• Bachelor’s degree in Computer Science, Software Engineering, Electrical Engineering, Aerospace Engineering, or a related technical field.
• 6+ years of experience developing mission-critical, real-time, embedded, or distributed software systems in defense, aerospace, robotics, autonomy, or similarly demanding environments.
• Demonstrated experience building software that operates in or near the chain from target cueing and engagement planning through effector or launcher execution.
• Strong proficiency in C++ and Python; working knowledge of Java, Rust, or Ada is a plus.
• Experience developing on Linux and comfort working in mixed software/hardware integration environments.
• Experience with real-time messaging, low-latency communications, and distributed system coordination (e.g. DDS, UDP, TCP, ZeroMQ, CAN, or similar).
• Experience owning software through design, implementation, integration, test, and field/debug cycles.
• Ability to reason about timing-sensitive systems, concurrency, interface contracts, and failure modes.
• Strong communication skills and the ability to work directly with cross-functional teams and external stakeholders.
• U.S. citizenship and ability to obtain and maintain a U.S. security clearance.
Preferred:
• Direct experience with fire control, battle management, engagement planning, weapon system integration, launcher control, interceptor systems, C-UAS, integrated air and missile defense, or naval combat systems.
• Experience building software for DoD, IC, or allied military customers in classified or restricted environments.
• Familiarity with software and systems safety practices such as hazard analysis, safety interlocks, fail-safe design, arming/inhibit logic, and verification of safety requirements.
• Familiarity with standards and processes such as MIL-STD-882E, interface control documentation, requirements traceability, and formal verification/validation workflows.
• Experience with hardware-in-the-loop, software-in-the-loop, lab integration, range events, flight test, or live-fire test support.
• Experience with sensor fusion, tracking, state estimation, guidance/control-adjacent systems, or kinematic/physics-based decision logic.
• Experience with DevSecOps and CI/CD tooling in regulated or classified environments (e.g. Git/GitLab, Jenkins, Ansible, Jira, Confluence).
• Familiarity with open architectures or defense integration patterns such as OMS/UCI, FACE, or similar modular mission-system approaches.
• Active Secret or Top Secret clearance.
