This position suits individuals who want to partner directly with enterprise customer engineering teams to turn AI prototypes into reliable production systems.

Key Responsibilities

Co-architect and co-build production-grade AI agents alongside customer engineering teams.
Secure the technical win during pre-sales by designing proofs of concept, answering technical questions, and guiding evaluations.
Assist organizations in deploying and operating agent-based applications like conversational agents, research assistants, and multi-step workflows.
Provide post-sale advice regarding system architecture, best practices, and roadmap-level decisions.
Deliver technical demonstrations, training sessions, and workshops tailored for developer audiences.
Collect field feedback and create reusable patterns, code examples, and cookbooks that scale across multiple clients.
Contribute code upstream occasionally when it directly improves customer outcomes.
Travel to customer sites approximately forty percent of the time for onboarding, deployment, and ongoing technical engagement.

Three or more years of experience in a relevant technical role such as software engineering, solutions engineering, customer engineering, or founding and product engineering, ideally within a startup or scale-up environment.
Strong fundamentals in systems, Python, and JavaScript.
Proven experience designing LLM-powered or agent-based applications that go beyond simple API calls, encompassing multi-step workflows, orchestration, and failure handling.
Comfort working directly with clients through architecture reviews, technical evaluations, and proofs of concept.
Ability to articulate complex technical trade-offs clearly and build trust with developers.
Personal accountability for project outcomes rather than just providing recommendations.
A bias toward action and enthusiasm for figuring things out dynamically.
Genuine excitement regarding the operation of AI agents in production settings rather than basic demos.

Nice to Have

Prior experience deploying AI agents in production environments, particularly utilizing frameworks like LangChain, LangGraph, or similar tools.
Working knowledge of LLM observability, evaluation, or guardrails.
Familiarity with cloud environments including AWS, GCP, and Azure, alongside containers and basic Kubernetes concepts.
Experience shipping and operating production software while owning systems under real-world operational constraints.
