About the Role
We're looking for a Senior Software Engineer (AI Agents) to build the core systems behind an intelligent automation platform used in highly complex, operations-heavy industries. You'll design and ship production-grade LLM systems, contribute across the stack, and play a key role in evolving both the product and technical architecture.
This is a high-ownership, high-impact role where you'll collaborate closely with the founding team, contribute to major architectural decisions, and build technology that solves real-world operational problems at scale.
What You'll Do
• Build and scale the core automation and AI agent systems that power the platform
• Work across the stack: backend APIs, data pipelines, orchestration layers, and frontend workflows
• Design and deploy agent-based LLM components for reasoning, extraction, and decision-making
• Collaborate directly with users to understand workflows and ship high-impact solutions
• Contribute to architecture discussions and help drive key technical decisions
• Write clean, reliable, maintainable code with strong engineering fundamentals
• Support roadmap execution and help elevate engineering standards as the team grows
Who You Are
• A senior-level engineer with experience in high-growth or startup environments
• Comfortable owning projects end-to-end with minimal oversight
• Strong in 0?1 product development and able to operate in ambiguous problem spaces
• Genuinely interested in applied AI and complex operational workflows
• Pragmatic, execution-focused, and thoughtful about long-term system design
What We're Looking For
• 5+ years of professional software engineering experience
• Strong full-stack capabilities (Python, TypeScript, React, Node.js, Go, or Python)
• Experience designing and shipping production backend systems and APIs
• Hands-on experience building or integrating LLM-powered or agent-based systems
• Ability to design scalable services and data pipelines
• Strong technical judgment and ability to make sound tradeoffs
• Clear communicator who can collaborate cross-functionally and with customers
Bonus Points
• Experience with retrieval pipelines, orchestration frameworks, or structured data extraction
• Prior experience at an early-stage startup
Why You'll Love This Role
• Meaningful equity and ownership at a high-growth startup
• Opportunity to help shape the core architecture of a category-defining AI platform
• Direct collaboration with founders on product and technical strategy
• High-trust environment with real autonomy
• The chance to modernize a critical global industry with automation and intelligent systems
