Backend Software Engineer

Wayflyer Backend Developer

Today's small businesses need a capital provider that keeps pace with their growth ambitions. Traditional financing options are slow, cumbersome and often out of reach. That's why we built Wayflyer.

Our technology allows us to assess businesses in minutes, generate financing offers that reflect their growth potential and send funds in as little as 24 hours. To date, we've deployed over $6bn to thousands of businesses worldwide, backed by Tier 1 banks like J.P. Morgan.

You'll be collaborating with ambitious colleagues from around the world. We have offices in Dublin, London, New York, Charlotte, Berlin and Sydney.

The challenge

We assess businesses in minutes and send funds in as little as 24 hours. The systems that make that possible need to be fast, reliable, and built to scale as we grow into new markets.

What you'll actually do

Design and develop scalable backend services using Python and Django, focusing on our core financial products

Build and maintain RESTful APIs that power our customer-facing applications and internal tools

Implement robust data models and database schemas to support our financial services infrastructure

Write clean, testable code with comprehensive unit and integration tests

Collaborate with cross-functional teams to design and implement new features and improvements

Optimize application performance and ensure high availability of our services

Participate in code reviews and contribute to technical documentation

Monitor and maintain production systems, ensuring reliability and security

Who thrives here

You should be comfortable making and defending technical decisions, while remaining open to feedback and alternative approaches. You'll need to balance technical excellence with business needs and help guide the team toward pragmatic solutions.

You excel at stakeholder management and can effectively communicate technical concepts to non-technical audiences. You're proactive in identifying and addressing potential issues before they become problems. We look for candidates with most or all of the below traits that can point to real experience applying them.

Bachelor's degree in Computer Science, Engineering, or related field, or equivalent practical experience

5+ years of professional experience in backend development with Python

Strong proficiency in Django, or other Python API frameworks (e.g. FastAPI, Flask)

Experience with SQL databases (preferably PostgreSQL) and ORM frameworks

Knowledge of API design principles and microservices architecture

Experience with AWS or similar cloud platforms

Solid understanding of version control with Git

Experience with testing frameworks (e.g., pytest, unittest)

Understanding of security best practices and data protection

Strong problem-solving skills and attention to detail

Excellent communication abilities and proven track record of successful team collaboration

Given what we do, experience in financial services, fintech and business-to-business organisations is particularly interesting to us.

We hire for range

What you're like as a person and how you treat people is a big deal for us. People love working with you. You're helpful and generous with your time and knowledge. People love helping you back. People know where they stand with you.

You're always looking to learn and grow, on a personal and professional level. And you're always looking to help others learn and grow by sharing your own knowledge and experience.

You know why diversity, equality, inclusion and belonging matters, and speak up when we can do better.

What this role could turn into

Engineers here tend to grow in the direction they're most interested in - whether that's deepening technical specialism, moving into architecture, or taking on more cross-functional ownership as we scale.

Location and working policy

Fully remote, Europe.

The good stuff

25 days off, plus public holidays, onboarding in our Dublin or London office. Equity - because you should own a piece of what you're building. Generous parental leave for primary and secondary caregivers. 60 days a year to work abroad from wherever you want.
