Backend Software Engineer

JOIN OUR TEAM

BetWarrior is a next-generation digital gaming company with a bold mission: to redefine the way people experience sports betting and casino entertainment across Latin America.

With a dynamic and diverse team, deep market insights, and cutting-edge technology, we're creating an experience that is personalized, responsible, and always player-first.

Great people, bold ideas, and a sharp focus on user experience set us apart.

Purpose

We are looking for a Backend Software Engineer with strong analytical skills and a product-oriented mindset to join our multidisciplinary teams. At BetWarrior, we are evolving toward a Spec-Driven Development (SDD) and Given-When-Then / Behavior-Driven Development (GDD/BDD) approach.

In this model, without traditional Business Analysts, the Backend team plays a key role: leading the initial technical analysis based on Product requirements, establishing the conversation with the Frontend team, and defining contracts, models, and interactions before writing a single line of code.

In this role, you'll

• Lead Technical Analysis and SDD: Take the lead in defining functional and technical specifications (OpenAPI/Swagger, data models, sequence/state diagrams). Produce clear documentation both for Product stakeholders and for the technical team to operate and maintain the solution.
• Foster Communication and Collaboration: Act as a communication bridge within the team. Work in small, autonomous squads, actively collaborating with Product, UX, and Frontend to align on endpoints and integration contracts.
• Build High-Traffic, Event-Driven Systems: Design and develop resilient, low-latency, highly concurrent backend architectures, with a strong focus on event-driven architectures.
• Champion Observability: Understand that quality goes beyond code: incorporate metrics, structured logging, and tracing from the design stage to ensure effective production monitoring.
• Behavior-Driven Design (GDD/BDD): Translate complex business scenarios into structured acceptance criteria (Given-When-Then / Gherkin), working closely with the Automation QA team.
  

What we look for in an exceptional candidate

• 5+ years of experience: Strong software engineering background in highly complex and scalable backend environments.
• Strong Java / JVM Ecosystem Expertise: Solid experience with Java and modern frameworks (Spring Boot), which are the core technical foundation of our platforms.
• Event-Driven Architecture Design: Experience with distributed systems, asynchronous processing, and messaging/event-driven tools (Kafka, RabbitMQ, etc.).
• Strong Technical Definition Skills (SDD): Demonstrated ability to lead upfront technical design through comprehensive specifications, technical diagrams, and API definitions.
• Observability Culture: Strong interest in system telemetry (metrics, logging, tracing) and troubleshooting production bottlenecks.
• Communication and Forward Thinking: Ability to articulate technical decisions, communicate architecture to non-technical stakeholders, and design maintainable, long-term solutions.
  

Bonus points if you also have

• Hands-on experience with Cloud infrastructure (AWS) and container orchestration (Docker, Kubernetes).
• Previous experience managing critical incidents and conducting post-mortems, using those learnings to anticipate potential failures during the design stage.
• Familiarity with reactive programming principles or advanced concurrency patterns.
  

How we do things

BetWarrior is a company in expansion. The team is fast-moving, collaborative, and demanding — with high standards for quality and a genuine commitment to building something that lasts. We are not looking for someone to fill a seat. We are looking for people who want to grow with the company, take ownership of their work, and be part of building a regional team that operates at a high level across multiple markets.

For the right person, this is an opportunity to join at a stage where your contribution is visible, your growth is real, and the path forward is defined by what you deliver — not by time in role.
