Senior Backend Engineer

Responsibilities:

• Design and build scalable, high-performance Java services and agentic microservices powering Tekion's AI platform.
• Develop and integrate LLM-based agent pipelines using LangChain, LangGraph, and LangFlow from prompt design through production deployment.
• Implement vector-based semantic search and knowledge retrieval using Qdrant, and model complex domain relationships using Neo4j graph databases.
• Build and maintain durable, fault-tolerant async workflows using Temporal, ensuring reliable execution of long-running agent orchestration tasks.
• Architect and implement multi-agent orchestration patterns for routing, tool use, memory management, and agent chaining across conversational and batch workloads.
• Establish and maintain observability standards: distributed tracing, structured logging, LLM call telemetry, latency dashboards, and cost-per-call monitoring.
• Lead feature development end-to-end from technical design through code review, QA sign-off, and production rollout.
• Collaborate with architects and senior engineers to influence system design and platform strategy.
• Mentor junior and mid-level engineers; conduct rigorous code reviews; drive adoption of engineering best practices across the team.
• Proactively identify performance bottlenecks, security gaps, and reliability risks in development and production environments.
• Champion quality, contribute to test strategy, promote TDD/BDD practices, and ensure adequate coverage across unit, integration, and contract tests.
