Engineering Manager, Product Engineering

About Us

Rillet serves accounting and finance teams—the financial brains of their companies. Our job is to help them run the numbers with impossible speed, accuracy, and insight. Rillet is the AI-native ERP middle market and enterprise companies trust for revenue recognition, multi-entity consolidation, and investor reporting. To enable real-time finance and a continuous close, Rillet rebuilt the general ledger from the ground up for the AI era. We serve Series A to public companies like Mercor, Scribe, and Function Health, and are a certified partner of top accounting firms like EY and KPMG.

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. The people who thrive at Rillet do not wait for assignments. They internalize the mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for. Our work revolves around our customers. The people who succeed here are energized by delivering what matters most—even when it was not part of the original plan.

Rillet is built on deep accounting expertise, and it takes people from many disciplines to build a category-defining company. You do not need to be an accountant to thrive here—but you do need to care deeply about the problems we solve and the impact our customers can create. Together, we combine the precision of accounting with the speed, creativity, and ambition of AI-native software to power the financial core of the world’s fastest-growing companies—and redefine what finance teams should expect from their software.

About the Role

Rillet's product engineering team is the engine behind everything our customers experience—and as our Engineering Manager, Product Engineering, you'll own it. You'll be owning a large part of our core product engineering team going through its next phase of growth. You're stepping in at a pivotal moment, with real scope to shape how the team is structured, how it operates, and where it goes. We're looking for someone who is as excited about what gets built as how it gets built—a leader who drives engineering excellence, partners deeply across functions, and develops the team that ships what our customers love.

We’re looking for teammates who are based near our New York City or San Francisco offices, or open to relocating. Our hybrid schedule brings the team together in person on Tuesdays and Thursdays, plus one additional flexible day each week. Some roles may spend more time in the office depending on the needs of the team.

Responsibilities

• Own product engineering for a large part of Rillet's engineering org—setting direction, shaping team structure, and making the organizational and architectural calls that unlock scale.
• Partner with product managers, designers, and subject matter experts to influence what we build, not just how we build it.
• Drive multiple high-stakes product initiatives from conception to launch, maintaining a high bar for quality and reliability.
• Lead, mentor, and develop a talented team of engineers, building the culture and craft standards that define great product engineering at Rillet.
• Recruit and onboard exceptional engineers who will help accelerate product development as we grow.
• Get hands-on with code during this critical growth phase, contributing directly to Rillet's product surface.

Requirements

• 4+ years managing product engineering teams at high-growth tech companies, with 6+ years in engineering overall.
• Experience managing multiple teams simultaneously—whether through managers or technical leads—and comfortable operating at that level of organizational complexity.
• Proven experience stepping into complex team situations and driving meaningful organizational change—you've done the hard work, not just the clean-slate builds.
• Strong cross-functional collaborator who translates seamlessly between technical and non-technical stakeholders and moves fast in dynamic environments.
• A culture carrier who sets a high bar and makes it contagious—you know what great looks like and help others rise to meet it.
• Drawn to hard, ambiguous problems and energized by building in environments where you're figuring things out as you go.

Nice to Have

• Experience scaling and subdividing engineering teams during periods of rapid growth.
• Recent hands-on experience with Kotlin, Java, or TypeScript and solid CI/CD practices.
• Background in fintech, ERP, or accounting software.
• Familiarity with enterprise readiness (SOC 2, SSO/SAML, audit logging, or similar).

Benefits

• Competitive pay and meaningful equity—be rewarded for the value you help create.
• Medical and dental coverage, including up to 100% of employee premiums and 90% of dependent premiums.
• 401(k) retirement plan.
• Flexible PTO, nine company-wide holidays, and paid parental leave for eligible employees.

Life at Rillet

• Grow with us—take meaningful ownership, expand your scope, and make an impact as Rillet scales.
• We’re hybrid-first, with teams centered in New York City and San Francisco and select remote roles.
• Offices stocked with snacks, regular team lunches and dinners, and time to connect as a team.
