US H-1B: cap-subject employers enter a lottery weighted by wage level — Level I gets 1 entry, Level IV gets 4 (DHS projected selection odds ≈15% at Level I to ≈61% at Level IV). Universities and non-profit research employers are cap-exempt. The $100,000 fee for new petitions from abroad is currently blocked by a court order (appeal pending).

About the role
Our mission is to automate coding. The first step in our journey is to build the best tool for professional programmers, using a combination of inventive research, design, and engineering. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code. ABOUT THE ROLE As a Software Engineer on the Agent Harness team at SpaceXAI, you’ll build the core agent behavior and capabilities that power agent experiences across Cursor products. This spans agent orchestration, tools, guardrails, and model behavior tuning—designed as a platform that SpaceXAI engineers can extend and depend on. Your work will also define the default Cursor agent experience (”Auto”), where users trust us to make the right model choices under real-world constraints. Example projects include: - Advancing the agent harness (agent loop, tools, prompts, execution environment, capabilities) used across Cursor products. This would shape and empower experiences like multi-agent coordination. - Improving the default Cursor agent experience (the “Auto” model setting): making smart model choices based on user needs, model capabilities, and cost appetite. - Shaping the default Cursor agent’s personality. - Launching new models on Cursor end-to-end — partnering with foundational model providers and our research team on integration, evaluation, and rollout. YOU MAY BE A FIT IF - You have built complex agentic products or infrastructure. - You have strong software engineering fundamentals and enjoy shipping production systems. - You have taste and strong opinions on model and agent behaviors. You stay up-to-date and informed on emerging research and industry trends. - You make good calls in the gray area: weighing data, user experience, and product taste when there isn’t a single “right” answer. - Experience building eval datasets or frameworks to understand and improve the performance of AI systems is a plus. - Experience building products or tools used by other engineers is a plus. APPLYING If there appears to be a fit, we'll reach to schedule 2-3 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team. #LI-DNI
