Job description

payabl. empowers businesses to grow through payments innovation and banking services. Our ambition is to expand our strong portfolio of global financial services and make them all accessible through our unified platform, payabl.one. As a licensed financial company with principal membership with card schemes, we specialize in global payments and multi-currency banking solutions.

The role is about:
We are looking for a Mid-Level Backend Developer to support our growing File Processing team. You will be a key contributor to our migration journey, helping us move legacy batch jobs into a modern Python ecosystem. This is an ideal role for an engineer who wants to dive deep into high-load data pipelines and financial orchestration in a fast-paced fintech environment.

  • Location: Remote from Portugal or Ukraine (Contractor arrangement)
  • Reporting to: Technical Lead

What you will do:

  • System Implementation: Support the re-architecture of legacy Perl batch jobs into modern, maintainable Python services.
  • Operational Reliability: Assist in implementing workflow orchestration (Prefect/Airflow) to ensure safe job re-runs and system stability.
  • Observability: Help instrument our services with logging and alerting (Grafana/CloudWatch) so we can monitor systems without direct production access.
  • Data Transformation: Work on data ingestion pipelines, moving raw data to S3 and transforming it into relational database records.
  • Collaboration: Participate in agile sprints and maintain clear English communication with the team and stakeholders.

What we need:

  • Python Expertise: 3+ years of backend development experience with Python.
  • Orchestration Exposure: Familiarity or hands-on experience with orchestration tools like Airflow or Prefect.
  • AWS Fundamentals: Exposure to AWS services such as S3 and Lambda.
  • Databases: Experience with relational databases, specifically MySQL.
  • Clean Code: You write intentional, human-readable code and can explain your implementation choices without relying on AI.
  • Curiosity for Product: You care about the business logic and "why" behind the code, especially regarding payment flows and reconciliation.
  • Problem Solving: Strong analytical skills and a proactive approach to troubleshooting.

Hiring Process:

  • Step 1 – Thinking in Action (40 minutes) Your first conversation will be with our Talent Acquisition team. We'll explore your background, career journey, motivations, and overall fit for the role. As part of this discussion, you'll also complete a short technical screening that will be reviewed by our engineering team. This stage helps us understand both your experience and how you approach technical challenges.
  • Step 2 – Build in Production (60–90 minutes) Meet with the Team Lead and technical experts for a practical assessment. Depending on the role, this may involve a live coding exercise or a real-world scenario designed to evaluate your technical skills, problem-solving approach, and ability to work through challenges similar to those faced by our teams.
  • Step 3 – Final Interview (45 minutes) The final stage is a group interview with senior members of our Technology squad, which may include the CTO, CPO, and Team Lead. Together, we'll discuss team fit, collaboration style, expectations from both sides, and any remaining questions about the role, team, or technology domain. This is also an opportunity for you to learn more about our culture and ways of working.

The perks of being a payabl.er: 

  • Grow with Us: Annual Learning Budget for professional development (eligible after probation)—because your growth is our growth.
  • Celebrate Together: We bring colleagues from all offices together for unforgettable company celebrations.
  • Global Collaboration & Events: Opportunities to participate in international company events and initiatives, connecting with colleagues from all regions and contributing to a truly global community

This is a fully remote role for candidates based in Portugal or Ukraine.

Let's embark on a journey to redefine the landscape of payments together. We're not just offering a role; we're inviting you to be a part of something bigger. Join our team, and let's innovate, disrupt, and lead the future of payments. Together, we can make an impact that resonates. Welcome to the team!
