Salary: $170,000–$275,000 USD

Company

hirify.global develops Fury, a robotic foundation model for defense that enables autonomous, natural-language control of robot fleets.

What you will do

• Design and advance the agent harness (agent loop, tools, prompts, execution environment, capabilities) used across the agentic stack.
• Integrate fullstack software with physical hardware systems and AI agents, ensuring robust low-latency communication across complex pipelines.
• Build simulation environments and game-engine-like frameworks to test and train agents before physical deployment.
• Own the connectors translating model output into physical action for real-world systems.
• Fine-tune frontier AI models and build data acquisition pipelines feeding the training infrastructure for agents.
• Work with warfighters to turn capability requests into production-ready agentic systems.

Requirements

• 5+ years of full-stack engineering experience in a startup or high-ownership environment.
• Experience building complex agentic products or infrastructure (agent loops, orchestration systems, tool-use frameworks) and strong opinions on agent/model behavior.
• Systems-oriented fullstack engineering experience integrating software with physical hardware or low-level systems.
• Exposure to simulation environments, game engines (Unreal, Unity, Isaac Sim), or robotics middleware (ROS/ROS2).
• Strong software engineering fundamentals: architecture, distributed systems, and real-time pipelines; ability to ship production systems.

Culture & Benefits

• Competitive base salary and bonus, plus meaningful equity.
• Premium medical, dental, and vision plans with $0 paycheck contribution.
• Competitive PTO and a company holiday calendar.
• Catered lunch daily and a fully stocked kitchen.
• Unlimited AI tokens and EV charging.
• Relocation assistance may be available depending on role eligibility.

Hiring process

• Interviews focused on agentic systems, architecture, and real-world integration experience.
• Technical evaluation of systems design, distributed/real-time pipelines, and shipping production software.
• Discussion of fit for building defense-focused robotic foundation model capabilities.
