About the role

Role embedded with Light’s top customers to redesign finance workflows, wire integrations, and deploy AI-native agents to modernize how multinational SaaS/tech finance functions operate. Founding motion in a new customer-motion with close collaboration with Account Managers, platform, and AI engineering.

Responsibilities

  • Embed with a customer's finance team, map and redesign their workflows AI-first
  • Wire the integrations - pull data from ERPs, banks, and billing into Light
  • Configure, ship, and supervise AI agents in production until the customer trusts them
  • Hand back a workflow the customer runs themselves, and train their team from go-live
  • Diagnose the edge cases the playbook doesn't cover, and ship the answer
  • Measure & prove the impact against a week-0 baseline
  • Partner two-in-a-box with your Account Manager, and pull in platform and AI engineering when you need them
  • Feed repeatable patterns to the Product roadmap

Qualifications

  • 3+ years close to how finance teams actually work - accounting, process design, consulting, or technical customer success
  • You build & tinker. Vibe coding, data pipelines, and LLM agents are tools you reach for, and you ship working software, not slideware
  • You're fluent enough in finance to hold your own with a Controller on multi-entity, consolidation, and reporting - and to know when a request won't work
  • You bring structure to messy problems and move fast: diagnose, prototype, harden, ship
  • You're comfortable in front of a CFO and next to an engineer, and you've delivered without formal authority over anyone
  • You use AI tools daily and have specific opinions on where they help in delivery and where they don't
  • Fluent English; additional European languages a plus
  • Bonus #1: Solutions or integration engineering background; experience mapping and redesigning finance processes and with AI agents in production (evals, guardrails, …)
  • Bonus #2: A finance / accounting qualification
