One of LATAM's fastest growing global Fintechs

About the Opportunity

We are partnering with one of the fastest-growing Fintech companies in LATAM—now global, hyper-scaling, and redefining the digital wallet and financial services ecosystem. This organization operates a high-volume, real-time transaction platform that impacts millions of users across several regions.

This is not a traditional corporate environment. It's a
true startup culture
:

  • No hierarchies
  • High accountability
  • A team that embraces big challenges and builds fast
  • A leadership mindset to early stage growth: bold, ambitious, and constantly pushing boundaries

If you are someone who
loves complex problems
, thrives in
scalable architectures
, and feels energized in
fast-paced, non-comfortable environments
, you will fit right in.

What You'll Do

As a
Senior Backend Engineer
, you will be a key contributor in designing and maintaining the core services that power the company's global financial ecosystem. You'll work on systems that move millions of dollars every day—requiring excellence, reliability, and deep technical judgment.

You will:

  • Design, build, and maintain backend systems, APIs, and databases
  • Contribute to distributed systems and microservices architecture
  • Work closely with product and engineering teams to deliver high-quality solutions
  • Participate in high-impact architectural decisions
  • Ensure system performance, stability, and scalability
  • Continuously improve availability, latency, monitoring, and resilience

Technical Requirements (Must-Have)

  • 7+ years working 100% with Java (mandatory)
  • Strong expertise in backend engineering for high-scale environments
  • Deep experience with PostgreSQL (design, optimization, performance tuning)
  • Hands-on experience with distributed systems & microservices
  • Strong understanding of cloud environments (AWS preferred)
  • CI/CD experience
  • Experience in Fintech, banking, or high-transactional environments is a strong plus
  • Advanced English (C1+) – mandatory
  • Valid work permit in the country where you apply (no cross-country relocation, but internal relocation is supported)

Cultural & Personal Fit (Critical)

We are looking for someone who is not only technically strong but also aligned with the company's culture. The right person is:


• Highly proactive
– doesn't wait to be told what to do


• Curious, bold, and not afraid to propose new solutions


• A problem-solver who simplifies complexity for technical and non-technical audiences


• Collaborative


• Someone who wants to grow with a company that is scaling at an absurd rate

Benefits

  • Monthly budget to spend on activities with your team
  • Transportation support
  • Online Friday meditation
  • Training budget
  • Birthday day off + gift
  • Lunch at the office, and more
  • Internal relocation bonus (country-specific)
