Who it suits
A good fit
- You like co-building an agent with a customer’s engineers.
- You want the proof of concept before the sale and the architecture after it.
- You’re glad to travel 40% of the time.
Think twice
- You don’t want to travel 40% of the time.
- You haven’t designed an agent past a simple API call.
- You want the work to stop at a recommendation.
What you’d do
- Co-architect and co-build production agents with the customer’s engineers.
- Run technical demos, training, and workshops for developers.
- Help customers deploy conversational agents, research agents, and multi-step workflows.
- Advise customers on architecture after the sale.
What they ask for
- You have 3 or more years in software, customer, solutions, or product engineering. Founding experience counts, and they prefer a startup or scale-up.
- You have strong Python, JavaScript, and systems fundamentals.
- You’ve designed agent or LLM applications past a simple API call, including 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 for deployment, onboarding, and ongoing work.
- On-target earnings are base salary plus variable pay at plan. Equity is separate.
