• Enhance AI data workflows by building scalable infrastructure for high-throughput data I/O, orchestration, and storage, leveraging distributed queues, databases, and message brokers.
• Drive engineering excellence by mentoring and guiding less experienced engineers, fostering collaboration, and ensuring high-quality development practices.
• Improve system reliability and customer experience by working with the Support team to troubleshoot and resolve issues within the team’s area of ownership.
• Shape the future of AI development by contributing to an AI platform used by leading research labs to train multi-modal large language models (LLMs).
• Advance innovation by staying up to date with industry trends, assessing new technologies, and incorporating relevant advancements into backend systems.
• Share knowledge and expertise through technical documentation, blog posts, research publications, and conference presentations, establishing thought leadership in AI infrastructure.
• Collaborate cross-functionally with engineers, product managers, and stakeholders to drive initiatives forward and develop solutions that meet customer and business needs.

What You Bring

• Strong technical expertise with 5+ years of experience in backend engineering, specializing in distributed systems and large-scale software architecture.
• Proficiency in backend technologies, including databases (Relational, Key-Value Stores, Cloud Buckets), queues, job management, message brokers, and streaming data.
• Experience building APIs using REST and GraphQL, with knowledge of backend development in Node.js (NestJS preferred).
• Fluency in programming languages such as TypeScript, Java, or Python, with a solid understanding of data structures and algorithms.
• Cloud expertise, with experience in at least one major platform (GCP preferred, AWS, or Azure).
• Strong problem-solving skills, able to break down complex requirements into actionable tasks and navigate ambiguity effectively.
• A proactive mindset, with a strong sense of ownership and the ability to thrive in a fast-paced, dynamic environment.
• Effective collaboration and communication skills, working across teams to drive projects to completion.
• Commitment to continuous learning, staying current with industry trends and leveraging AI tools like Cursor and GitHub Copilot for development efficiency.
