This role sits at the intersection of backend engineering and AI-powered product innovation, focused on building and operating high-performance services that power intelligent, user-facing features at scale. You will design and deliver backend systems that support LLM-driven experiences, ensuring reliability, scalability, and efficiency in production environments. The position requires strong ownership of end-to-end services, from design and implementation to monitoring and optimization. You will work closely with cross-functional teams including product, data science, and engineering to bring experimental AI capabilities into production. The environment is highly collaborative, data-driven, and focused on continuous improvement, with a strong emphasis on observability and system performance. This is a hands-on engineering role ideal for professionals passionate about backend systems, distributed architectures, and applied AI in real-world products.

• Design, build, and maintain scalable backend services and APIs supporting AI-powered product features.
• Deliver end-to-end solutions with ownership over quality, latency, reliability, and cost in production environments.
• Develop and operate distributed systems capable of handling high traffic and complex workloads.
• Instrument services using observability tools to monitor performance, detect issues, and ensure system stability.
• Collaborate with product, data science, and engineering teams to evolve AI-driven features from experimentation to production.
• Review code and system designs critically, contributing to technical decision-making and architecture discussions.
• Improve system performance and reliability through continuous optimization and debugging of production issues.
• Work with event-driven architectures and asynchronous systems to ensure scalability and resilience.
• Contribute to engineering best practices, including testing, documentation, and deployment standards.

Requirements:

• Strong experience in backend development with Python and production-grade systems.
• Solid experience with AWS, including serverless architectures (e.g., Lambda).
• Strong knowledge of SQL and NoSQL databases (PostgreSQL, DynamoDB, OpenSearch), including data modeling and access patterns.
• Experience designing, deploying, and maintaining APIs in production environments.
• Hands-on experience with distributed and event-driven systems (e.g., Kafka, SQS).
• Strong understanding of observability practices, including metrics, logs, tracing, and alerting tools (Grafana, Prometheus, OpenTelemetry).
• Experience working with microservices and distributed architectures at scale.
• Strong problem-solving skills and ability to work with loosely defined technical challenges.
• Excellent communication skills and ability to collaborate across technical and non-technical teams.
• Nice to have: experience with LLM-based systems, prompt engineering, retrieval workflows, or agentic AI systems.
• Nice to have: experience with data pipelines (e.g., Airflow) and AI coding tools (Cursor, Copilot, Claude Code).
• Nice to have: experience with Kotlin, Go, or Java for cross-team or distributed system work.
