About the Role:

You’ll be a key engineer focused on building and owning the systems that allow tens of thousands of businesses to offer and manage 401(k)s. This is a very hands-on role: owning full stack services and APIs end-to-end, shipping production code, and evolving the architecture to support future needs. You’ll partner closely with product, compliance, and operations to turn complex financial requirements into reliable software. If you like solving hard problems and having a real impact on people’s lives, then we want to work with you.

About the Team:

The Core 401(k) team makes offering a 401(k) to employees a no brainer for every company. We’re responsible for ensuring companies don’t have to think about complex laws, rules, and regulations. We build features and capabilities for small businesses that are often unavailable through legacy providers. What we do matters. Hundreds of thousands of people are trusting us with their retirement, and that’s something we never lose sight of.

Here’s what you’ll do day-to-day:

• Design, build, maintain, and ship services and features that allow companies to offer and manage 401(k)s to their employees.
• Identifying opportunities to extend and modify the architecture of existing systems to support new capabilities
• Identify, codify, and evangelize engineering best practices
• Partner with product, design, and operations to scope work and deliver production-ready solutions.
