Java Developer - Senior
Synectics, Alpharetta, GA, United States
REQUIREMENTS
Knowledge of security engineering relevant to LLM apps (prompt injection, data exfiltration patterns).
Domain expertise in the product area (e.g., telecom operations, network management, customer support).
Strong cross-functional collaboration with product, security, and platform teams.
Ability to translate business workflows into agent capabilities and measurable outcomes.
Comfortable operating in ambiguity and iterating from prototype hardened production.
5-7 years of experience in Python with 1-3 years of experience in Java
Agentic / LLM Engineer experience using LangGraph agentic framework
RAG / Knowledge graph
AWS & Kubernetes
Experience in AI observability platforms (Langsmith / Langfuse)
Core Software Engineering Skills (Must Have)
Strong coding in Python (often primary) and/or TypeScript/Java.
Solid fundamentals: data structures, APIs, concurrency/async, error handling, clean architecture.
Experience building microservices and integrating with internal/external APIs.
Familiarity with CI/CD, automated testing, code reviews, and release management.
Agentic / LLM Engineering Skills (Must Have)
Designing and implementing agent workflows: planning tool selection execution verification.
Tool/function calling patterns and building reliable tool interfaces (idempotency, retries, timeouts).
Prompt engineering plus prompt/version management and safe prompt templating.
Handling non-determinism: evaluations, guardrails, deterministic fallbacks, and replayable runs.
Building multi-step orchestration (state machines, DAGs, workflow engines, or agent frameworks).
Retrieval + Knowledge Integration (Often Required)
Building RAG pipelines: chunking, embeddings, indexing, retrieval strategies, reranking.
Working knowledge of vector databases (e.g., Pinecone, pgvector, FAISS, Weaviate) and search.
Grounding and citation approaches; freshness and permission-aware retrieval.
Reliability, Safety, and Governance
Implementing guardrails: PII redaction, prompt injection defenses, policy filters, allow/deny tool lists.
Designing for observability: tracing agent steps, tool calls, latency, token/cost metrics.
Building robust fallbacks (rule-based flows, smaller models, cached answers, human escalation).
Secure handling of secrets and credentials; least-privilege tool access.
Evaluation & Quality (Critical for Agentic Systems)
Creating evaluation suites: golden tasks, regression sets, scenario tests, adversarial tests.
Defining success metrics (task completion rate, groundedness, hallucination rate, latency, cost).
Experience with A/B testing or online evaluation in production.
Platform/Infrastructure (Preferred)
Cloud experience (AWS/Azure/GCP), containers (Docker), optionally Kubernetes.
Familiarity with scalable data pipelines and queues (Kafka/SQS/PubSub) for async agent work.
Experience optimizing inference costs/latency (model choice, batching, caching, token reduction).
Experience with frameworks like LangChain, LlamaIndex, or workflow engines (Temporal, Step Functions, Airflow).
