Published on April 13, 2026

We're looking for great people to join our growing team.

Full Stack Engineer (Ruby on Rails, Python, React)

About Wealthbit

We’re shipping products that people need to build financial freedom in their lives. Wether that’s getting out of crippling debt or building an investment portfolio that ensures their future is secure, our aim is to ensure people have the tools and knowledge they need to succeed.
We started with a platform used by financial advisors, to make the financial advice process more transparent and have their clients (everyday people) be more involved in understanding and building financial plans they believed in and could make sense of, putting people in greater control of their finances.
Next up, we’re working on bringing a complete Financial Freedom Programme™ to companies to help their employees systematically and proactively work towards improving their financial health.
We’re focused on simplifying finances to make a real impact.

What we care about

  • Authenticity: What you see is what you get. We value each member of the team showing up authentically, and make space for other to do the same.
  • User focus: We build real products for real people. We focus on solving problems for them that make meaningful and lasting impact.
  • Curiosity: We embrace curiosity, challenge the status quo, and see setbacks as opportunities to learn.
  • Simplicity: We believe that making things more complex is easy, making things simple is hard. So we do what’s hard. From concepts, features, products, if it’s not simple then it’s most likely going to be hard to follow or use. Neither of which is good for users.
  • Proactive Ownership: You own your features, tools, and processes. If you see something that needs improvement, push for it to get done.
  • Autonomy: Everyone in the team is responsible for how they deliver their work, what solutions they choose, and what they decide to prioritize.

Who we’re looking for

We’re expanding our product team, and this role is about working on the planning platform for transparent and impactful financial advice.
We’re hiring a Ruby on Rails Product Engineer, excited to challenge themselves by talking to users, getting involved with design and developing an opinion on what should be built, then making it happen.
What you’ll be doing
  • 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.
Role specific outcomes you’ll drive.
  • 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.

Requirements

  • Proven Experience: You have 3-5+ years of professional experience in full-stack web development, with a track record of shipping and maintaining complex applications.
  • Technical Proficiency: You have strong proficiency in Ruby on Rails and a modern JavaScript framework (we use React). You have some experience with, or would be willing to learn, Python for data modeling and analysis.
  • Systems Thinking: You can balance long-term scalability with short-term needs, writing code that is not just functional but also maintainable and robust.
  • User-Centric Mindset: You are passionate about building products for people. You can turn complex requirements into intuitive experiences that meet user and business needs.
  • Effective Communication: You can articulate complex technical ideas clearly and collaborate effectively with team members from different disciplines. You are comfortable communicating directly with customers to solve their problems.
  • Initiative & Problem Solving: You proactively identify gaps, propose solutions, and take the initiative to drive meaningful change without waiting for permission.
  • Asynchronous Collaboration: You proactively own your goals, manage your time independently, and communicate with clarity, particularly in written form.

Bonus points if you have:

  • Previous experience in FinTech or with financial modeling concepts.
  • Experience building and maintaining API integrations between different systems.
  • Direct experience providing customer support in a technical role.

Other Important Things

  • Fully Remote: Work flexibly from home. For those in Johannesburg or Cape Town, the team occasionally meets up for important events.
  • Growth Mindset: We know imposter syndrome is real and can discourage fantastic people from applying. Don’t let it deter you—we’re all learning.
  • Retirement Benefits: Access to a group provident fund, including risk benefits (death, income replacement, funeral cover), helping secure your financial future.
  • We Work Hard, And Rest Well: We have high standards but recognize that rest and well-being are what fuel peak performance.
If you’re excited about building products that are that genuinely changes lives, we’d love to meet you.
