- Rotate among the product groups to build capabilities that help win customers and expand the platform, including customer-embedded engineering work
- Fold speech-to-text, voice synthesis and dialogue-model upgrades into production systems
- Tune and troubleshoot live systems while weighing response time, expense and caller satisfaction at enterprise scale
- Collaborate tightly with colleagues in product and machine learning; every engineer drives several initiatives at once
Profile
- Five or more years as a full stack engineer
- Fluent in either Python or TypeScript
- Hands-on work with LLMs, for example multi-turn agents, prompt design or LangChain
- Track record shipping software for very large user bases within a startup or fast-growing company
