Staff Software Engineer (AI Agents)

TL;DR

Staff Software Engineer (AI Agents): Build the core architecture for AI agents to interact with and control complex real-world physical systems with an accent on agent orchestration, tool integration, low-latency communication, and execution environments. Focus on designing the agent harness, owning model-to-physical-action connectors, and enabling simulation-first testing and training pipelines.

Location: Remote US, Sunnyvale, California

Salary: $230,000 - $380,000 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.
• Collaborate with warfighters to turn capability requests into production-ready agentic systems quickly.

Requirements

• 10+ 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) with strong opinions on agent/model behavior.
• Systems-oriented fullstack engineering experience integrating software with physical hardware or low-level systems.
• Exposure to simulation environments and 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

• Premium medical, dental, and vision plans with $0 paycheck contribution.
• Competitive PTO and company holiday calendar.
• Meaningful equity and a competitive base salary + bonus compensation package.
• Unlimited AI tokens.
• Catered lunch daily and a fully stocked kitchen.
• EV charging.

Hiring process

• Interviews focused on agentic systems architecture, integration with real-world systems, and production engineering fundamentals.
• Technical evaluation of simulation/testing approach and low-latency/distributed systems experience.
• Discussion of ownership, collaboration style, and ability to deliver production-ready agentic systems.
