Pinwheel - Building the future of financial services in partnership with the biggest brands

“I love my banking app!” said no one, ever.

Pinwheel is on a mission to change that. We believe banks and financial service providers represent the greatest opportunity to build 10x better experiences, especially in the AI age. We’re building the next generation of financial products alongside some of the biggest names in the market including Robinhood, DoorDash, Chime, Cash App, Credit Karma, American Express, Discover, Intuit, Acorns, Visa and more.

If you’re excited by the idea of having your work touch and impact the lives of hundreds of millions of consumers, Pinwheel is the place for you.

If you get stoked about building products alongside the biggest brands in the world, Pinwheel is the place for you.

If you want to join a scrappy, hustling team that is obsessed with defining the future of financial services, Pinwheel is the place for you!

Pinwheel has raised $77M from top-tier investors such as Coatue, Notable, First Round, Upfront, Primary, American Express, Franklin Templeton, Indeed, Semper Virens and more.

**This role is hybrid with 3 days a week in our NYC office.

**This position does not offer visa sponsorship now or in the future.**

Who are we looking for?

We’re hiring a senior full-stack Product Engineer for our Product Engineering team. The PE team builds all the things our customers and their users use: public APIs, embedded SDKs, customer management dashboard, and more.

Our Product Engineering team is lean and works very closely with Product to ensure we’re evolving Pinwheel’s product in ways that bring maximum value to our customers. We are a high-velocity team where we balance four main workstreams: support of customers, deliver the roadmap, proactively improve the product and keep-the-lights-on.

What will you do?

Here are some projects you might work on in your first six months:

• Help us build our Bill Switch product that helps our customers drive account primacy through migrating their users’ subscription spend to their new accounts
• Contribute to a new API version that improves our contracts and formalizes recent product direction in our platform’s code
• Help us firm up and improve our tax product for next tax season
• Clean up old code that no longer serves our current product direction and leave the codebase better than you found it
• Build a new customer dashboard API that aligns with our stack and opens up future expansion possibilities in customer dashboard functionality
• Build new integrations with banking platform partners and help us improve existing implementations to make them more effective

In general, your responsibilities in this role would include:

• Deeply understand our customer needs and design systems to solve them
• Build, scale, and evolve the data models, services, and systems that power our APIs
• Design and ship impactful new functionality in our products, especially focused on our internal and customer-facing back-end APIs
• Maintain and improve our Python-based microservice stack
• Create and improve tooling, processes, and engineering standards across the team
• Mentor engineers and help the team grow

What qualifications are we looking for?

• 5+ years of experience building and maintaining full-stack applications, specifically with data modeling, application logic, and API design
• Prior experience working at an early-stage startup or small tech company
• Expertise with modern back-end languages/frameworks (e.g. FastAPI, Django, Rails, Gin)
• Expertise with modern frontend web frameworks (React, Vue, etc.)
• Played key implementation roles in projects with multiple teams and engineers
• Excited by working closely with customers
• Responsibly uses AI on top of fundamental skills, doesn’t replace them
• Maintains a high bar for technical quality and continues to level up
