Senior Gen AI Software Engineer

Minimum Bachelors Degree and 8 yrs of relevant experience.

You are a seasoned software engineer who has built and operated meaningful production products, ideally including zero-to-one work spanning backend services, data, and user interfaces.

You have shipped LLM-powered or AI-assisted products beyond a demo and understand the practical challenges of reliability, context, tool use, provider changes, latency, cost, and changing model behavior.

You are highly proficient in Python and comfortable working in TypeScript and React, with strong fundamentals in API design, data modeling, SQL, and testing.

You understand how to build the broader system around a model, including its data, tools, instructions, permissions, feedback loops, and measures of quality.

You can define success criteria, investigate failures, and use testing, feedback, and production signals to improve AI experiences over time.

You exercise strong product and engineering judgment, choosing when a problem calls for traditional software, an LLM-powered approach, or a thoughtful combination of both.

You communicate complex technical ideas clearly and collaborate effectively with domain experts and non-technical partners.

You are comfortable working through ambiguity, making informed decisions with incomplete information, and changing direction when evidence shows a better path.

You are a lifelong learner with strong but flexible opinions, and you thrive on giving and receiving constructive feedback.

Experience as an early engineer, startup founder, or in a similarly high-ownership environment where you moved quickly from ambiguous problems to shipped products.

Experience with advertising technology, campaign optimization, performance marketing, analytics products, or other data-rich B2B software.
