Design, build, and maintain scalable backend services and APIs that support a high-throughput analytics platform.
-
Architect and evolve distributed systems with a strong focus on reliability, maintainability, and performance at scale.
-
Own full lifecycle delivery of backend initiatives, including technical design, implementation, testing, observability, and production support.
-
Integrate AI capabilities such as LLMs, agentic frameworks, and related pipelines into core backend services and product features.
-
Improve system reliability through robust observability practices, including logging, tracing, monitoring, and incident response.
-
Collaborate closely with Product and Engineering stakeholders to define requirements, shape architecture, and deliver technical solutions.
-
Contribute to engineering excellence through code reviews, design discussions, and continuous improvement of backend standards and practices.
-
Work with cloud infrastructure environments such as GCP or AWS to support scalable, production-grade systems.
Requirements:
-
Strong experience as a Senior Backend Engineer in high-ownership, product-driven engineering teams.
-
Proficiency in at least one modern backend language such as Python, Go, or Ruby, with strong architectural and system design skills.
-
Solid understanding of distributed systems, RESTful APIs, event-driven architectures, and scalable backend design principles.
-
Experience optimizing database performance at scale, including indexing, query tuning, and working with large production datasets.
-
Hands-on experience with cloud platforms such as GCP (preferred) or AWS.
-
Strong knowledge of observability practices, including monitoring, logging, tracing, and incident management in production systems.
-
Proven ability to independently deliver complex backend features in fast-paced engineering environments.
-
Bonus: experience with LLMs, prompt engineering, or agentic AI frameworks (e.g., OpenAI, Anthropic, MCP).
-
Bonus: familiarity with analytical databases (e.g., BigQuery, ClickHouse), search systems (e.g., Elasticsearch), or event-driven tooling (e.g., Kafka, Pub/Sub).
-
Bonus: experience with AI-assisted development tools and workflows such as Cursor, Copilot, or Claude Code.
-
Bonus: exposure to NLP, customer feedback analytics, or open-source contributions/public speaking.
