Engineering Manager (Financial Systems)

Government technology has failed the public for decades, and Americans have been conditioned to expect websites from the 90s for essential public services.

Kaizen exists to strengthen trust in American public services by building technology that residents and public servants are proud to use. We partner with local, state, and federal agencies to replace legacy systems with modern, AI-native software that is worthy of the people they serve. We started in outdoor recreation, and now we're building toward something much larger — the software layer that powers how Americans access any government service.

Our platform already reaches 40 million residents across 50+ agencies in 17 states.

Founded in 2022 and based in New York City, Kaizen has raised $35 million from NEA, a16z, Accel, 776, and Carpenter Capital. We're builders, designers, and operators who believe that beautifully designed software shouldn’t be a luxury in government. It’s how you earn trust back.

This is a hybrid role based out of our New York City HQ. Candidates must reside in New York or be able to commute to New York City to work out of our office at least three times a week (Tuesdays - Thursdays).

As our Financial Systems EM, you’ll be building the financial systems that power this mission - ensuring governments and residents alike can trust every transaction, every time. You’ll get to solve some of the hardest technical challenges in fintech and civic tech, shape the foundation of our platform, and play a key role in scaling an early-stage startup on its way to nationwide impact. You will be responsible for owning and building our financial systems - payments, processors, reporting, and accounting infrastructure. These systems are among the most sensitive parts of our product and codebase, and as we scale to larger, more sophisticated customers, they’re holding us to higher standards of accuracy, compliance, and reliability. This is a highly technical role with leadership responsibility: ~80% hands-on engineering and ~20% people management. You’ll collaborate closely with product and platform teams to design simple, abstracted financial interfaces, while ensuring our systems are accurate and built to scale.

The government technology modernization wave is happening. Agencies are being pushed to change, and they need partners who can move fast and build well.

We have the contracts. We have the agency relationships. We have the platform. We need the engineers.

If you want to spend the next few years shipping software that actually matters — not another B2B SaaS dashboard, not an internal tool nobody uses — and you want to do it at a company moving aggressively into one of the most consequential markets in tech, this is the role.

You need a detailed ticket to know what to build next. You think AI tools are a crutch. You want to own one layer of the stack and never leave it. You're more comfortable in a 500-person organization than a small team where everyone's accountable. You need the problem fully defined before you start moving. Or if you're looking for low-stakes work — because what we build touches real people in real moments that matter: accessing benefits, families navigating public services, constituents interacting with their government at its most critical touchpoints. This work is serious. The people we serve deserve serious teams.
