Role Overview

The Deployed Engineering team collaborates directly with organizations building production-grade artificial intelligence agents.

Provide post-sale advice regarding architecture, best practices, and product roadmap decisions.
Facilitate technical demonstrations, workshops, and training sessions for developer audiences.
Collect field feedback and create reusable patterns, cookbooks, and example code for broader client use.
Contribute code upstream occasionally when it directly enhances customer implementation success.

Requirements

Minimum of 5 years of relevant technical experience in software engineering, customer engineering, solutions engineering, or product engineering, preferably within a startup or scale-up environment.
Solid proficiency in Python, JavaScript, and core systems fundamentals.
Demonstrated experience designing LLM-powered applications or agents that extend beyond basic API calls, including orchestration, multi-step workflows, and failure management.
Proven comfort in direct customer interactions during technical evaluations, architecture reviews, and proof-of-concept phases.
Ability to articulate technical trade-offs clearly and establish credibility with developer stakeholders.
Strong ownership of end-to-end outcomes combined with a bias for action and problem-solving initiative.
