Expertise in REST and gRPC, with proficiency in Node.js and JavaScript. Proficiency in AWS, along with experience using at least one additional cloud platform such as GCP or Azure. Advanced knowledge of Kubernetes and Terraform in production environments. Experience operating highly available production systems, including monitoring, scalability, reliability, performance optimization, and operational tooling. Strong knowledge of SQL and NoSQL databases, including PostgreSQL, MySQL, MongoDB, Cassandra, or DynamoDB. Familiarity with graph databases such as Neo4j and vector databases or embedding infrastructure for semantic search and retrieval. Hands-on experience building and operating LLM-powered systems in production, including evaluation, validation, regression testing, tracing, and failure analysis. Working knowledge of LangSmith or comparable LLM observability and evaluation tools; familiarity with OpenAI, Anthropic, or similar model providers is a plus. Ability to contribute across the full stack, with a strong understanding of frontend architecture and the ability to debug, design, and ship across frontend, backend, infrastructure, and AI systems. Understanding of large-scale enterprise software systems, including architecture, integration, deployment, modernization, and long-term maintainability. Proven track record of operating at Staff+, Principal Engineer, or comparable scope, independently driving complex technical initiatives and delivering high-impact outcomes with minimal supervision. Salary Range: $300,000 - $500,000 + Bonus + Equity Blitzy is an equal opportunity employer committed to building a diverse and inclusive team. We believe different perspectives make us stronger. Base salary ranges are determined by country, role, level, experience, and skills. The range displayed on each job posting reflects Blitzy's good faith determination of the minimum and maximum targets for new hire salaries across all US locations.
