AI Engineer

The core responsibilities for the job include the following:

Agents that run finance workflows:

• Own end-to-end finance workflows as autonomous agents: invoice-to-pay, three-way matching and exception handling, GL close tasks, reconciliation, and vendor and compliance checks.
• Design tool and action surfaces over ERP systems, control flow, error recovery, human-in-the-loop checkpoints, approval and segregation-of-duties guardrails, and full auditability of every action taken on financial data.
• Build against production enterprise surfaces: SAP APIs, ERP user interfaces via computer-use agents, documents, and file-based integrations using LangGraph, LangChain, or custom orchestration. Memory and the finance knowledge graph.
• Own agent memory: context management (windowing, summarization, and compaction), long-term memory, retrieval and forgetting policies, and cross-cycle state for long-running agents.
• Model the finance domain as a knowledge graph, with vendors, invoices, POs, GRNs, GL accounts, contracts, approvals, and their provenance in a graph database (Neo4j or equivalent), alongside vector search, ensuring every output can be substantiated for finance and audit review.

Evaluation and model strategy:

• Build and extend our evaluation platform: golden datasets, workflow-level metrics, regression gates in CI, automated judging calibrated against human review, and drift detection on live traffic. No change is released without a measured evaluation delta.
• Work across model families (Anthropic, OpenAI, Google, and open-weight) and own routing, which model handles which step at what quality, cost, and latency point, with tiering, cascading, and provider failover. Scale and platform.
• Own latency, throughput, and unit economics for agents and pipelines operating at large document and transaction volumes, maintaining p50/p95/p99 latency and cost-per-workflow targets as the customer base grows.
• Maintain the API surface (FastAPI, REST) that delivers these capabilities into our products, and mentor engineers working alongside AI systems.

Requirements:

• Agents in production: demonstrated experience delivering a multi-step agent that performs actions in a production system, with a clear understanding of its failure modes and the controls used to contain them.
• Memory: experience designing the memory and context strategy for a long-running agent, including retention, summarization, and pruning decisions.
• Evaluation: hands-on experience building an evaluation harness, including dataset construction, metric selection, and calibration of automated judging.
• Multiple models: delivered systems on at least two model providers or families, with experience migrating a live workload between them.
• Scale: experience operating an LLM or ML system in production at significant request volume, with measurable before-and-after results.
• Our Stack: Python, LangGraph / LangChain, Anthropic, OpenAI, and Google model APIs, FastAPI, PostgreSQL with pgvector, Neo4j, Elasticsearch, Java/Spring Boot and React, GCP and AWS, Docker, and an in-house evals platform and in-house OCR.
• Familiarity is helpful but not a prerequisite.
• Preferred / General Requirements: Finance, accounting, audit, or ERP (SAP) domain exposure, or a strong interest in developing domain-specific depth.
• Computer-use or browser automation agents; GraphRAG and ontology design; document AI/OCR; fine-tuning or serving open-weight models.
• LLM tracing and observability (LangSmith, Langfuse, OpenTelemetry); enterprise AI security, governance, and compliance frameworks.
• Regular use of AI coding agents in day-to-day development; a significant share of our codebase is authored this way.
