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
