Strong proficiency in TypeScript, Python, C#, or similar technologies with experience building scalable APIs, microservices, and distributed systems. Practical experience building enterprise AI applications using large language models, including agents, retrieval augmented generation, orchestration frameworks, and model optimization. Hands-on experience with cloud-native technologies, serverless applications, event-driven architectures, data pipelines, relational and NoSQL databases, vector databases, observability tooling, and automated deployment pipelines. Demonstrated ability to own services or features end to end with limited supervision. Experience mentoring engineers through code review, pairing, debugging, documentation, and promoting engineering excellence through testing and continuous improvement. Proficiency in AI concepts and tools to streamline workflows and enhance operational efficiency, with a commitment to responsible and ethical AI use.

About you
You are a motivated and collaborative engineer passionate about applied AI and software engineering excellence. You thrive in a team environment, enjoy solving complex challenges, and are committed to delivering high-quality, scalable, and reliable software solutions. You have a strong sense of ownership and are eager to mentor others and contribute to shared frameworks and responsible AI practices.
