Senior 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.
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.
Design and develop resilient, low-latency, highly concurrent backend architectures, with a strong focus on event-driven architectures.
Understand that quality goes beyond code: incorporate metrics, structured logging, and tracing from the design stage to ensure effective production monitoring.
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 in software engineering background in highly complex and scalable backend environments.
Solid experience with Java and modern frameworks (Spring Boot), which are the core technical foundation of our platforms.
Experience with distributed systems, asynchronous processing, and messaging/event-driven tools (Kafka, RabbitMQ, etc.).
Demonstrated ability to lead upfront technical design through comprehensive specifications, technical diagrams, and API definitions.
Strong interest in system telemetry (metrics, logging, tracing) and troubleshooting production bottlenecks.
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.

Reliability – Deliver with quality and consistency
Teamwork – Collaborate, challenge, and grow together
