About the team

SumUp empowers merchants all over the world to build a thriving business thanks to wide ranging product lines and functionality that helps speed up business operations & manage the day to day. Think payment solutions, POS systems, accounting software, reporting, loyalty and much, much more.

As a Senior Software Engineer in our Expansion Latam squad, you will have full ownership of designing, implementing, and maintaining software solutions that directly impact SumUp's growth in the region. You will join a mission-critical team responsible for a varied product portfolio, including Payments, Onboarding, Payouts, and Taxes.

Currently, we run an Own Acquiring operation in Chile, a vital pillar for our success. Your primary mission will be to de-risk this operation, lead the migration to modern payment exchanges (like VCX), and scale our platform to support new markets and card brands. This is a high-stakes environment where your technical decisions directly affect real-time financial transactions.

What you’ll do

Design & Ownership: Take full ownership of the LATAM payments platform, improving its architecture, resilience, and security.
High-Impact Delivery: Lead the migration from legacy packages to VCX (Visa Clearing Exchange) and strengthen our VPC (Visa Platform Connect) implementation.
Technical Excellence: Introduce new tools and best practices to improve team productivity, resolve incidents, and reduce technical debt.
Collaboration: Work closely with Product Managers and global teams (Payments Processing & Post Processing) to align technical solutions with business needs.
Mentorship: Act as a technical reference and mentor for mid-level and junior engineers within the squad.
Automation: Identify opportunities to optimize workflows, such as automating clearing processes for major brands like Mastercard.

What you’ll need

Senior Technical Expertise: Proven experience in code design, automated testing, CI/CD, performance optimization, and resilience patterns in distributed systems.
Tech Stack: Advanced proficiency in Golang and/or TypeScript/JavaScript.
Data Management: Deep understanding of relational databases (e.g., PostgreSQL), including schema modeling and query optimization.
System Design: Strong experience with microservices, scalability, and message queues (RabbitMQ or Kafka).
Communication:Advanced English proficiency (written and spoken). You will need to collaborate with global stakeholders and present technical ideas clearly.
Leadership: Experience leading medium-to-high scale technical projects and a proactive "self-starter" mindset.
Adaptability: Comfort navigating ambiguity and complex payment flows across multiple markets.

Nice to have

Fintech & Payments: Previous experience in the payments domain or acquiring integrations knowledge.
Cloud & Infrastructure: Hands-on experience with AWS (EKS, RDS, S3, SQS) and container orchestration (Docker, Kubernetes).
Multi-language: Proficiency in Java, Kotlin, or Ruby.
Observability: Experience with monitoring tools like Grafana and Prometheus.
