Résumé du poste

Arango is hiring a Customer Solution Architect to lead the technical customer relationship for our GraphRAG-enabled AI platform in Paris. You will own end-to-end design, pilot, and production deployment, turning customer problems into scalable graph-based architectures with retrieval capabilities.

The role requires deep graph expertise, 5+ years in software/solution architecture, and strong Python and AI tooling experience.

Qualifications

Deep graph knowledge with graph data modeling and AI-backed retrieval.
5+ years in software engineering, solution architecture or technical professional services.
Strong Python and applied AI skills with familiarity in LLM tooling.

Responsabilités

Own the technical customer relationship across the full lifecycle: discovery, design, pilot, production, expansion.
Run discovery with sponsors and operators to identify high-value use cases and real business outcomes.
Design target architectures on Arango's multi-model platform, including graph data models, AQL traversal, and GraphRAG retrieval.
Define success criteria, SLAs/SLOs, data access and governance requirements, and phased delivery plans.
Build reference implementations and prototypes that demonstrate value early: graph schema, data connectors, pipelines, and orchestration.
Guide production deployment with CI/CD, IaC, and proper testing with customer engineers.
Architect retrieval across graph traversal, vector search, and hybrid approaches; orchestrate tool and agent calls.
Establish evaluation practices and iterate on prompts, models, and retrieval strategy.

Description du poste

About ArangoDBArango makes your business data AI-ready, giving agents, apps, and assistants trusted context at scale. Every answer is traceable. Every decision is governed. No more stitching together a vector store, a graph database, a search index, and a governance layer added as an afterthought. Arango’s Contextual Data Platform has it all built in, not bolted on. Trusted by organizations including NVIDIA, HPE, Zscaler, the London Stock Exchange, the U.S. Air Force, NIH, Siemens, and Articul8, Arango helps enterprises move from AI pilots to reliable production systems faster while lowering infrastructure complexity and total cost of ownership. Arango is a proud member of the NVIDIA Inception Program and the AWS ISV Accelerate Program. Stop building Frankenstacks. Start building with Arango. Learn more at arango.ai. We believe great innovation happens when curious, driven people collaborate. We are committed to building a diverse and inclusive team and supporting our employees and interns as they learn, grow, and contribute to shaping the future of enterprise AI.

About The RoleArango is hiring a Customer Solution Architect to be the primary professional services interface between Arango and the customers deploying our AI product suite. You own the technical relationship end to end, from first discovery through production and expansion. Your job is to turn a customer's problem into a working architecture on Arango's multi-model platform and its GraphRAG and knowledge-graph capabilities, prove value early, and guide the customer's team through deployment and adoption. The role sits where solution architecture, graph data modeling, and applied AI meet. It suits someone who can hold a design conversation with a customer's chief architect in the morning and review a GraphRAG retrieval design with their engineers in the afternoon. Deep graph expertise is not optional here. It is the core of how Arango's AI suite delivers value, and the CSA is expected to be the customer's most trusted source of graph and GraphRAG design judgment.

Key Responsibilities

Own the technical customer relationship as the primary professional services contact across the full lifecycle: discovery, design, pilot, production, and expansion.
Run discovery with customer sponsors, domain experts, and operators to identify high-value use cases for Arango's AI product suite, and qualify them against real business outcomes.
Design target architectures on Arango's multi-model platform, including graph data models, AQL query and traversal patterns, and GraphRAG retrieval design tailored to the customer's domain.
Define success criteria, SLAs/SLOs, data access and governance requirements, and a phased delivery plan from proof of value to production.
Build reference implementations and prototypes that prove value early: graph schema, data connectors, GraphRAG pipelines, tool and agent orchestration, APIs.
Guide production deployment into secure, observable services alongside the customer's engineers, with CI/CD, infrastructure-as-code, and proper testing.
Architect retrieval across graph traversal, vector search, and hybrid approaches (chunking, embeddings, ranking, caching), and orchestrate tool and agent calls.
Establish evaluation practices and iterate on prompts, models, retrieval strategy, and graph structure using offline and online metrics and A/B tests.
Design data pipelines (ETL/ELT), vector indices, graph ingestion, and metadata governance.
Define monitoring for quality, drift, hallucination and guardrail events, latency, and cost, and stand up alerting and dashboards with the customer.
Architect role-based access, secrets management, audit logging, PII redaction, and content safety controls.
Meet customer compliance requirements (SOC 2/ISO 27001, GDPR/CCPA, HIPAA as applicable).
Produce architecture documentation, runbooks, and reusable patterns, and train customer engineers and end users.
Act as the voice of the customer to Arango's product and engineering teams, shaping the roadmap with what we learn in the field.

Required Qualifications

Deep graph knowledge (central to this role). Hands-on expertise in graph data modeling, graph query and traversal (AQL, or equivalents such as Cypher or Gremlin), graph algorithms, and knowledge-graph design for AI. Direct experience building GraphRAG or knowledge-graph-backed retrieval for LLM applications.
5+ years in software engineering, solution architecture, or technical professional services, including building and operating production systems.
Strong applied AI and Python skills, with a solid grasp of data structures, systems design, concurrency, and networking.
Strong database skills across graph, NoSQL, key-value, and document models. Multi-model experience is valued given Arango's platform.
Hands-on experience with modern LLMs and tooling (OpenAI/Anthropic/Llama, Hugging Face, LangChain/LlamaIndex, function and tool calling).
Retrieval and vector databases (FAISS, pgvector, Pinecone, Weaviate, or similar), and hybrid retrieval that combines graph and vector.
Cloud and containers (AWS/GCP/Azure), Docker/Kubernetes, IaC (Terraform/CloudFormation), and CI/CD.
Observability (metrics, logs, traces) and performance tuning for latency-sensitive services.
Excellent customer-facing communication, with the ability to lead technical conversations from the executive level down to the engineering team.

Nice to have

Direct ArangoDB experience, or prior work deploying a graph database in production.
Search and IR fundamentals (BM25, hybrid retrieval, re-ranking, ColBERT, cross-encoders).
Front-end or full-stack experience (TypeScript/React, Next.js) for light UI prototyping.
MLOps platforms and evaluation frameworks (MLflow, Weights & Biases, Ragas, promptfoo, DeepEval).
Model adaptation and inference optimization awareness (LoRA/PEFT, DPO, distillation, quantization, vLLM/TGI/TensorRT-LLM), enough to advise on tradeoffs rather than to hand-build.
Domain experience in finance, healthcare, public sector, manufacturing, or retail.
Security and compliance familiarity: data residency, KMS/HSM, private networking.
French government or industry experience.

What success looks like (6–12 months)

2 to 4 customer deployments of Arango's AI suite live in production against agreed uptime, latency, and cost targets.
Measurable quality and business outcomes (task accuracy, deflection rate, cycle time) backed by evaluation and telemetry.
Reusable graph and GraphRAG reference architectures and connectors adopted by the broader delivery team and by customers.
Customer teams enabled and self-sufficient, with runbooks, documentation, and training in place, and strong satisfaction and NPS.
A credible field feedback loop feeding Arango's product and engineering roadmap.
