Job description

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

Our Mission

At Wealthbit, we're on a mission to transform financial well-being. We believe in empowering individuals and families to live lives full of choice and opportunity. While our company-wide Financial Freedom Programme serves employees directly, your role will be pivotal to a different, yet connected, mission: to empower the financial advisors who guide them.

You will be a core member of the team building our specialised platform for financial advisors. Your mission is to create powerful, intuitive tools that help advisors deliver scalable, consistent, and high-impact financial advice to their clients. By enabling them, you amplify our ability to foster financial well-being on a massive scale.

The Role

As a Full Stack Engineer, you will be instrumental in developing and shaping the platform that financial advisors use every day. You'll work across our entire stack, from building robust backend services in Ruby on Rails to creating intuitive user interfaces with React.

A unique and critical part of this role involves working with Python to maintain, modify, and improve our sophisticated financial projection models. While you don't need to be a Python expert on day one, a foundational understanding and a strong desire to learn are essential.

You won't be working in a silo. This role requires close collaboration and building integrations with our B2C product team. You will also be directly involved in the success of our users by providing technical customer support for the advisor platform you help build.

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.

Responsibilities

• Develop, test, and maintain our full-stack application using Ruby on Rails and React.
• Take ownership of our Python-based financial projection models, working to improve their accuracy, performance, and capabilities.
• Collaborate with the product, design, and B2C engineering teams to translate requirements into well-engineered solutions.
• Build and maintain critical integrations between the advisor and B2C platforms.
• Provide technical customer support for the advisor platform, troubleshooting issues and communicating directly with users to ensure their success.
• Participate actively in code reviews, architectural discussions, and team best practices to elevate the entire team's output.

What You'll Bring

• 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 a strong desire 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:

• 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.
