Engineering Manager, Platform Engineering

WHAT WE DO Rillet serves accounting and finance teams. Our customers are the financial brains of their companies. Our job is to help them run the numbers with impossible speed, accuracy, and insight. Rillet is an AI-native ERP that can drive a zero-day close. We are different because of our unified source-of-truth data model, hundreds of best-in-class native integrations (Stripe, Ramp, Salesforce, etc), automated & auditable workflows, multi-entity consolidation, and quickly expanding army of specialized AI agents (e.g., accrual, audit, P&L flux, board decks, etc). These earn us a consistently perfect customer satisfaction score https://www.g2.com/products/rillet/reviews. High-growth AI customers like Mercor, and Function Health love our ship velocity, because their financial stack needs to scale as quickly as they do. This huge market is ours to take. We have raised $100M from leading investors (including Sequoia, a16z, Iconiq, Oak HC/FT, and First Round) to help everyone run their numbers at the speed of AI. WHO WE ARE Rillet’s pace is not for everyone. Intelligence is table stakes. To succeed here, you need extreme speed, agency, and flexibility. Successful Rilleteers do not wait for assignments. They internalize a mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for. Work revolves around our customers. Successful Rilleteers are energized by delivering the most important things, even those that weren’t in the original plan. In this role, you do not need to be an accountant. But you do need to appreciate the value that our customers can create for their own company when we equip them with the perfect financial tools. Successful Rilleteers love powering the financial core of the world’s fastest-growing companies. WHO WE NEED Rillet's platform is the foundation every engineer builds on - and as our Engineering Manager, Platform, you'll own it. Developer experience, observability, operational efficiency, core infrastructure - the systems that determine how fast and how well we move as a company. You're stepping into a broad surface area spanning platform and integrations, with real ownership to set direction, grow the team, and make the architectural calls that let a fast-moving org scale without friction. We're looking for a platform-minded engineer-leader who cares as much about developer productivity as uptime - someone who sees internal tooling and observability as features to be crafted, not boxes to be checked. We're looking for teammates who value in-person collaboration and are within commutable distance of our NYC office (or willing to relocate). Team members work in-office Tuesdays and Thursdays, plus one additional flexible day. WHAT YOU'LL DO - Own the architecture, infrastructure, and developer tooling that every engineer at Rillet depends on - from CI/CD and deployment practices to the observability and operational efficiency that keeps us shipping fast and safely at scale. - Build and champion the internal tooling and developer experience that makes engineers at Rillet faster than engineers anywhere else. - Set technical direction for how we build reliability, security, and compliance into our systems from the ground up - including the design and scalability of our external API. - Hire and develop high-caliber platform engineers across a growing surface area, establishing the culture and craft standards that define great platform work at Rillet. - Partner with engineering leadership to define roadmap priorities and translate ambiguous problems into clear technical plans. WHO WE'RE LOOKING FOR - 4+ years managing platform, infrastructure, or developer tooling teams at high-growth tech companies, with 6+ years in engineering overall - Background as a backend engineer who moved into platform work - you understand what it means to build for other engineers, not just alongside them - Deep experience with observability tooling, CI/CD, and clou
