Senior Software Engineer, Partner Onboarding

About the role

As a Senior Software Engineer on our Partner Onboarding team, you will build industry-first products that allow businesses to launch their 401(k) in as little as five minutes, driving our business growth. You will collaborate with domain experts to design, build, test, and own systems and processes for servicing 401(k) plans and making our customers happy. As reliability is key to earning our customers’ trust, you will build robust systems that are observable, maintainable, and scalable. As an engineering organization, we:

• Value continuous improvement - we care about documentation, security, durability, not just throwing features over the wall.
• Help each other be better engineers - we leave things better than we found it.
• Aspire to collaborate seamlessly - we ensure our software is improving the customer experience.

What you get to do every day

• Design, build, and maintain our user experiences for both external and internal customers
• Work on business-critical, foundational services which serve as the data funnel of our entire platform
• Improve complex processes and systems to make them more robust and require less human intervention
• Collaborate with other engineers and stakeholders to share knowledge and build expertise
• Develop ownership over domains in our system and make informed engineering tradeoffs
• Advocate for and delight internal and external users
• Direct AI agents across the full development lifecycle — from prototyping and implementation to debugging and code review — operating as the architect and decision-maker while AI handles the building
• Expand what's possible with AI tooling — identify opportunities to automate repetitive engineering work, improve code quality through AI-driven review, and share effective patterns with your team

What you bring to the role

• 6+ years of experience building and maintaining software in production
• Desire to work with the following technologies: Node, TypeScript, React, AWS and PostgreSQL
• Proficiency in leveraging AI coding assistants (e.g., GitHub Copilot, Cursor, ChatGPT) to accelerate development cycles and improve code quality.
• Top notch communication skills. You can communicate well with engineers and non-engineers alike
• Strong desire to learn, think creatively, and share knowledge with others
• Enjoy mentoring other engineers and deeply review their code
• Proactive and empathetic mindset - you love to roll up your sleeves to fix problems for our customers
• Past experience working in startups and/or fintech
