• Owning product features end-to-end: This means that you originate ideas based on user feedback, your intuition and aligning them with our strategy and goals. It also means that you own the success of your work, which includes understanding how users are using what you build, collecting feedback and prioritizing iteration. • Working with design: We expect everyone in the team to have the basics of owning their own UX of your work. You’ll work with design to refine things, but it’s up to you to think through where this might be necessary. • Doing support: Currently, we work on monthly rotations for customer support, where one person owns customer support for a month. This fits our current scale, where work can still be done. If this gets more intense, we’ll move to a different structure like bi-weekly changes. • Writing pitches and documenting your work: We don’t believe documentation for the sake of documentation is useful, so we focus on documentation as a clear way to communicate our ideas, keep track of decisions, feedback, and work progress - especially since we’re a fully remote team. You’ll be expected to put your thoughts down, share it with the team, and keep your feature docs up to date as you work. • High-Impact Advisor Tools: You will build and ship high-quality, reliable, and intuitive features that solve real-world problems for financial advisors, making their work more efficient and effective. • Accurate Financial Projections: You will enhance and maintain the accuracy and performance of our core Python-based financial projection models, ensuring the advice delivered is built on a solid foundation. • A Cohesive Platform Ecosystem: Through effective collaboration and well-built integrations, you will ensure a seamless experience between our advisor platform and our B2C application. • Robust and Scalable Systems: You will contribute to a clean, well-tested, and maintainable codebase that can scale as our business and the needs of our users grow.
