“This is a builder’s job for 1 to 3 years of experience. You’d travel to customer sites 40% of the time.”
Who it suits
A good fit
- Have 1 to 3 years in a technical role and have built an agent or LLM application past a simple API call
- Like working with a customer during a proof of concept
- Can travel to customer sites 40% of the time
Think twice
- Have more than 3 years of experience
- Don’t want 40% travel
- Haven’t built an agent or LLM application past a simple API call
What you’d do
- Co-architect and co-build production agents with the customer’s engineers.
- Own the technical win in pre-sales, including proofs of concept and evaluations.
- Help customers deploy and operate agents, and advise them after the sale.
- Run demos, trainings, and workshops, and turn field lessons into example code.
What they ask for
- You have 1 to 3 years in software, customer, solutions, founding, or another technical role.
- You have strong Python, JavaScript, and systems fundamentals.
- You’ve built agent or LLM applications with multi-step workflows, orchestration, and failure handling.
- You can explain a tradeoff to a technical customer and own the outcome.
How it works
- You’d travel 40% of the time to customer sites.
