About The Role

We're looking to add an experienced backend engineer to our exceptional team to help support our goal of expanding access to, and improving the quality of, financial planning at all levels.

You'll work across our Django codebase — from evolving established systems to building new features and areas of the platform — with the autonomy to make technical decisions and the responsibility to own the results. We value simple, pragmatic solutions that solve today's problems while keeping tomorrow's needs in mind. You'll balance shipping quickly with performance, security, and long-term code health while working with the team to make thoughtful architectural decisions.

To thrive in this role, you should be innately curious — a critical thinker and natural problem solver. We're looking for a humble team player, seeking to integrate and adapt to established standards, while bringing fresh new ideas and perspectives for discussion. Time management, attention to detail, and strong communication are essential to success in our organization. Most importantly, you should be a lifelong learner eager to understand not just the code, but the inner workings of the application itself.

What You'll Do

• Build and own backend features from planning through implementation, review, release, and ongoing improvement across our existing Django codebase and new areas of the application.
• Design and optimize database queries and data models to keep the platform performant as we serve thousands of clients.
• Build secure, reliable systems that protect sensitive financial and personal data.
• Collaborate with other engineers to make thoughtful architectural decisions that support future needs without over-engineering today's solutions.
• Think critically about requirements, identifying technical pitfalls, edge cases, or ambiguity before they become problems.
• Actively participate in code reviews, providing thoughtful and timely feedback to maintain code quality and keep the team moving quickly.
• Investigate production issues, narrow down root causes, and know when to bring in others to help resolve them.

Qualifications

Required

• 6+ years of professional Python experience, including 3+ years building production applications with Django.
• 2+ years of professional experience designing, building, and maintaining RESTful APIs in production using Django REST Framework, FastAPI, or similar frameworks.
• Strong Django fundamentals, including ORM, migrations, transactions, performance, debugging, and application architecture.
• Strong relational database fundamentals, including SQL, data modeling, indexing, and query performance.
• Demonstrated experience partnering with business stakeholders to clarify evolving requirements and deliver complex backend projects across established codebases and new development.
• Experience using AI coding tools such as Claude Code or Cursor while maintaining full responsibility for understanding and validating the resulting code.
• Strong communication skills with both engineering peers and business stakeholders.

Nice to Have

• Experience with AWS, Celery, task queues, and production observability tools such as Sentry.
• Experience building SaaS or FinTech products.
• Experience building MCP (Model Context Protocol) servers or tools that connect AI assistants to application data and functionality.
• Familiarity with tax planning, Roth conversions and retirement planning, insurance, or estate planning.

Our Engineering Culture

• Remote-first with flexible schedules across time zones
• High trust, high communication — we share progress, questions, and blockers early, often, and openly
• Preference for pragmatic code prioritizing consistency and maintainability
• Code reviews as learning opportunities, not gatekeeping
• Practical over perfect — we ship working solutions that help real users and embrace iteration
• End-to-end ownership mindset — it's not just about finishing tickets, it's about creating a great user experience

• JavaScript
• Vue.js
• In house design system driven by:
• native Javascript, HTML, and CSS
• Bootstrap-Vue
• Backend driven by:
