We’re looking for a Senior Financial Systems Manager to join our FP&A team in Montreal. As a Senior Financial Systems Manager within FP&A, you will own Lightspeed's enterprise performance management (EPM) platform end-to-end and act as the primary liaison between Finance and the Data Office, IT, and broader business systems on everything that touches financial planning infrastructure. You will be the technical owner of Pigment, our new planning system, and a hands‑on builder driving its architecture, integrations, and evolution. What you’ll be doing: Platform Ownership: Own Pigment as a system, including data models, calculation logic, dimensional structure, security and access design, version control, and release management. Make the architectural calls that determine how planning works at Lightspeed for years. Integrations & Data Architecture: Partner with the Data Office on upstream data quality, source system integrations, and the dimensional standards that flow through ERP, EPM, and BI. Own the integrity of how data moves between BigQuery, NetSuite, Workday, Salesforce, Looker, and Pigment. Standards & Team Empowerment: Define the technical excellence required for our Pigment environment by creating robust modelling guidelines, scalable patterns, and best‑practice implementations. Drive team‑wide proficiency and confidence through the creation of comprehensive documentation and targeted training programs for FP&A. Drive Strategic Impact: Collaborate closely with the Director, FP&A leadership, and senior partners in Finance and Data to convert business requirements into technical platform solutions.

Deep fluency in EPM data modelling: dimensional design, calculation logic, allocations, security architecture, and integrations. Strong understanding of finance source systems and data flows across ERP, data warehouse, and BI. Direct experience with BigQuery, NetSuite, Workday, Salesforce, or Looker is a strong plus. SQL proficiency for diagnosing upstream data issues. Python or scripting experience is a plus. Working knowledge of SOX compliance and its implications for financial systems, access reviews, and change management. AI fluency. Use LLMs, copilots, and automation tools in your workflow. Excitement about what’s next matters. Comfortable working across vendors, internal IT, and Data Office partners to land complex technical decisions. Ability to write clear specs, requirements documents, and technical documentation that holds up under scrutiny. Comfort explaining technical tradeoffs to senior finance leaders without losing them in jargon. Cross‑functional fluency. Worked across Data, Accounting, IT, and business teams, not just within Finance. Bias toward structural thinking. Know when to ship a workaround and when to push back and design it properly. Nice to haves: Fluency in SaaS and payments business mechanics is a plus. Pigment Certified Modeler certification or equivalent platform credential. Public company finance environment exposure. Experience supporting a system migration end‑to‑end. FP&A foundation, not pure systems administration. Built or supported revenue models, expense forecasts, headcount plans, or unit economics frameworks and understand why they exist. You’ll enjoy: A flexible work environment that empowers you to do your best work. A culture that celebrates performance. The chance to make an impact in a team that’s big enough for career growth, but lean enough to make your voice heard. Career‑defining opportunities.
