Senior Software Engineer (backend, Node.js)

About Us:

Capitalize is a mission-driven company solving critical problems in the $20 trillion retirement savings market with delightful products, scalable technology, and a world-class team.

At our core, we’re modernizing the $1 trillion in retirement account transfers (401(k) rollovers) that happen annually and currently involve manual, paper-based processes. By doing so, we’re helping the almost 20 million Americans who change jobs each year with a 401(k) do the right thing with their assets rather than lose them to fees and taxes.

Our Enterprise offering includes a full suite of enterprise-grade APIs used by leading financial institutions to help their users find and transfer retirement accounts as part of their core funding flows. Our Consumer offering helps individuals digitally locate forgotten 401(k)s and consolidate them into one of our brand-name financial partners.  

We’ve raised $35mm from leading venture capital investors including RRE Ventures, Canapi Ventures, Greycroft, and others, and we’ve been recognized as one of TIME’s 100 Best Inventions and by Forbes as one of the Top 50 Fintech Companies in the US.

• Write high-quality, maintainable code in JavaScript and Java.
• Leverage AWS services to deploy, scale, and monitor our systems.
• Build and optimize Docker containers for deployment and scaling.
• Contribute to improving the architecture and design of the platform to handle increasing scale and complexity.
• Ensure data security and compliance to established standards
• Troubleshoot, debug, and optimize systems to handle large amounts of data and traffic.
• Participate in code reviews and mentorship of junior engineers.

Required Skills & Experience:

• Strong proficiency in backend development, especially using JavaScript (Node.js) and Java.
• Hands-on experience with AWS (EC2, Lambda, S3, RDS, etc.) for deploying scalable systems.
• Familiarity with containerization technologies (Docker, ECS).
• Experience in designing and implementing asynchronous workflows (e.g., message queues, event-driven architecture).
• Familiarity with CI/CD pipelines and DevOps tools for infrastructure automation (e.g., Terraform, Ansible).
• Knowledge of data security best practices and compliance requirements.
• Experience working with relational databases (e.g., PostgreSQL, MySQL).
• Strong problem-solving and debugging skills.
• Effective independent contribution, with a sense of ownership for creating great features, and a desire to work in “green-field,” brand new initiatives
• Experience working on products with rapid feature development, including fast iterations and tight feedback loops during QA processes
• Desire to take on growth-oriented initiatives outside of core feature work 
• Excellent communication and collaboration skills.
