Software Engineer; Agent Systems Gardena, California,

AIxCrypto is a U.S.

-listed company dedicated to building a world-leading ecosystem that integrates AI and blockchain while bridging Web2 and Web
3. Its core products include the Bes Trade DeAI Agent and the AIxC ecosystem products. Our mission is to build the core infrastructure of an AI-driven global economy that empowers more intelligent, more transparent, and more efficient capital appreciation and value regeneration. Our vision is to create a world where real-world value flows freely, securely, and intelligently across information networks — empowering global users to effortlessly participate in the co‑creation and sharing of value within the crypto economy.

As a Staff Software Engineer (Agent Systems) in our Crypto Department, you will architect and implement agentic systems that convert user intent into safe, explainable, multi‑step research and execution workflows. You’ll design Google Agent Development Kit (ADK)–based multi‑agent graphs, define tool/function schemas, integrate retrieval pipelines, and establish guardrails, evaluation, and observability to deliver grounded, low‑latency experiences across web and mobile.

• Agent Orchestration (Google ADK):
  Build single/multi‑agent graphs (planner–tool–critic loops), manage state/memory/sessioning, and use ADK built‑in evaluators for trajectory/factuality; deploy with Vertex AI Agent Builder/Agent Engine under clear latency/cost/grounding SLAs.
• Retrieval & Grounding:
  Implement RAG that fuses curated sources with on‑chain/market/social signals; source attribution/citations and freshness controls; reranking where needed.
• Realtime UX & BFF:
  Stream intermediate results and progressive answers; expose agent endpoints to web/mobile via BFF with typed contracts and back pressure handling.
• Reliability & Safety:
  Enforce prompt‑injection defenses, PII redaction, policy filters, allow/deny‑lists, and safe execution/rollback; maintain gold sets and red‑teaming suites.
• Evals & Observability:
  Instrument tokens/latency/cost; build offline eval sets and online A/B/interleaving tests; track citation coverage and tool‑action success; version prompts/policies and canary new tools.
• Documentation & Standards:
  Author ADRs, tool specs, and runbooks; coordinate with Security/Compliance and Product.

• Bachelor’s degree or above in Computer Science, Software Engineering, or a related discipline.
• 8–10+ years software engineering with 3+ years in LLM/agentic systems or production NLP/IR.
• Strong backend skills (Python, Node.js or Java), APIs (REST/Graph
  
  QL/Web Socket), and cloud delivery (Docker/K8s on AWS or Google Cloud).
• Retrieval & vector search: embeddings, rerankers, vector DBs (pgvector/FAISS/Milvus), chunking/routing, and latency/cost‑aware caching.
• Evals & guardrails: factuality/grounding tests, safety filters, jailbreak resistance, and human‑in‑the‑loop workflows.
• Observability: tracing tokens/latency, cost controls, logs/metrics/traces; CI/CD and canarying for prompts/tools/policies; feature‑flag frameworks.
• Security foundations: secrets management/rotation, signed webhooks, OAuth2/OIDC, mTLS where appropriate.

• Crypto context: order‑book deltas, market data semantics, on‑chain explorers, and precision math for prices/quantities.
• Advanced techniques: hybrid retrieval (graph + dense), reranked fine‑tuning, distillation, caching strategies, and structured JSON outputs with validators.
