[Hiring] Backend Software Engineer @BetWarrior

Role Description

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 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.

Qualifications

• 5+ years of experience in highly complex and scalable backend environments.
• Strong Java / JVM Ecosystem Expertise with solid experience in Java and modern frameworks (Spring Boot).
• 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.

Requirements

• 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.

Benefits

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.

We expect every team member to live our values:

• Accountability & Ownership – Take charge, own your craft.
• Reliability – Deliver with quality and consistency.
• Teamwork – Collaborate, challenge, and grow together.
• Winner Spirit – Compete with purpose and grit.
• Wellbeing – Build a career that energizes you.
• Curiosity & Innovation – Keep questioning. Keep improving.
