Rillet • New York, NY

About The Position

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. 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.

Requirements

• 5+ years of software engineering experience with a track record on complex, large-scale projects
• Deep expertise in AWS — this is our primary cloud and you'll own it
• Hands-on experience with CI/CD, observability tooling, and distributed systems
• Comfortable making technical decisions and navigating hard tradeoffs at whatever scope your role demands
• Energized by building in a fast-moving environment where the playbook is still being written

Nice To Haves

• Experience building or maintaining third-party integrations (ERP, fintech, or similar)

• Experience owning and scaling public-facing APIs
• Familiarity with enterprise readiness (SOC 2, SSO/SAML, audit logging, or similar)
• Kotlin, Java, or TypeScript experience
• Prior experience at a high-growth startup

Responsibilities

• Own the infrastructure, CI/CD, and developer tooling that keeps our engineering team shipping fast and safely at scale
• Set the technical direction for reliability, security, and compliance — building these in from the ground up rather than bolting them on later
• Shape the design and scalability of our external API, turning it into a competitive asset for customers and partners
• Partner with engineering leadership to define roadmap priorities and translate ambiguous problems into clear technical plans
• Raise the bar for engineering quality through design reviews, mentorship, and hands-on collaboration
