Detalles del empleo

Descripción completa del empleo

Hello! We're Cashea , and we're on a mission to give Venezuelans back the opportunity to access credit through a BNPL business model. Since our launch in 2022, we've been dedicated to promoting financial inclusion. Today we have more than 9 million active users, both consumers and merchants, and we've become a trusted brand in Venezuela, winning hearts and minds .

About the role

We're looking for a Senior Backend Engineer who owns systems, not just services. You'll design the backend that moves money for millions of people — which means correctness, resilience, and performance aren't nice-to-haves, they're the job.

You'll work close to Product and to other engineering teams, shaping how our platform scales as we grow. This is hands-on: you'll write code, make architectural calls, and be on the hook for how your services behave in production. The growth path here rewards engineers who go deep, raise the bar around them, and make the system better than they found it.

Overall you will...

Design and build robust, scalable backend services in Node.js and NestJS (Express).
Create and maintain high-performance RESTful APIs that other teams can build on with confidence.
Build for financial correctness — idempotency, reconciliation, retries, and well-defined failure states.
Model and manage relational data, primarily in PostgreSQL, with performance and integrity in mind.
Make architectural and system-design decisions, and own the trade-offs behind them.
Ensure optimal service performance and own production deployments end-to-end.
Raise the engineering bar through code reviews, pairing, and clear technical standards.
Mentor engineers and lead technical discussions, leaving the team stronger than you found it.
Move fast across multiple workstreams in a dynamic, high-growth startup environment.

Qualifications

Bachelor's degree in Computer Science or a related field, or equivalent practical experience.
5+ years of backend development experience, with solid depth in Node.js and NestJS (Express).
Proven experience designing and operating RESTful APIs in production.
Advanced knowledge of relational databases, preferably PostgreSQL.
Experience writing unit and integration tests, and treating quality as part of delivery.
Strong grasp of design principles and architectural patterns.
Track record of shipping features independently and owning service performance in a fast-moving context.
Ability to communicate complex technical concepts clearly, and to mentor others effectively.
Excellent problem-solving and analytical thinking, with genuine curiosity about new technology.

Desirable skills

Experience with cloud platforms, specifically Google Cloud Platform (GCP).
Knowledge of containers and orchestration, such as Docker and Kubernetes.
Experience with messaging and queuing systems like RabbitMQ, Kafka, or Pub/Sub.
Experience building in fintech, payments, or credit.
Spanish and English proficiency.

Why you'll love working at Cashea

At Cashea, we have a work culture based on trust and purpose. If you need a clue as to why we are a good choice, these are our core values:

We don't work on autopilot. Everything we do is intentional. We love to develop ideas with full awareness of the impact they can have on our users.
Your creativity and curiosity are our most important assets.
Your voice matters. We listen and make space for ideas and feedback. Everyone belongs, and what's important to you is important to us.
We value transparency. Clarity keeps us connected and grounded.
Last but not least, we focus on real impact.

If you want to work with us, fill out the application. We'd love to meet you!
