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 Frontend Software Engineer with an analytical mindset and a product-oriented perspective to join our multidisciplinary teams. At BetWarrior, we are evolving toward a Spec-Driven Development (SDD) and Given-When-Then / Behavior-Driven Development (BDD) model.
We are not simply looking for a developer who turns designs into code, but rather an engineer who takes end-to-end ownership of the problem: from refining and technically specifying requirements (state diagrams, API contracts, Markdown/Gherkin specs) to delivering robust and scalable solutions.
In this role, you'll
Lead technical analysis based on initial Product/UX Acceptance Criteria. Define sequence/state diagrams, API contracts, and write functional specifications (MD/Gherkin) before writing code.
Model complex state flows and design resilient interface architectures capable of operating in high-traffic, low-latency environments.
Work closely with Product and UX teams in small, autonomous squads, acting as the technical bridge between business ideas and viable architectures.
Translate business scenarios into clear acceptance criteria and well-structured system behaviors, actively collaborating with the Automation QA team.
Design components and abstractions with long-term maintainability in mind, anticipating edge cases, critical bugs, and bottlenecks
What we look for in an exceptional candidate
5+ years of experience in software engineering, providing the foundation needed to have worked through the level of complexity required for problem-solving.
Strong analytical and problem-solving skills, with experience managing critical state flows in web applications or concurrent platforms.
Demonstrated ability to create technical documentation prior to development (OpenAPI/Swagger specs, UML/sequence diagrams, Markdown technical specs).
Familiarity with defining business-oriented scenarios using Given-When-Then / Gherkin.
Strong foundations in computer science or software engineering (design patterns, data structures, browser performance), beyond narrow expertise in a particular library.
Experience or working knowledge of JavaScript/TypeScript, UI libraries/frameworks such as React, and Node.js environments.
Bonus points if you also have
Experience working on high-traffic, high-concurrency, or real-time data platforms.
Experience going through complex production incidents or post-mortems that have shaped your approach to preventing errors through clear specifications.
Knowledge of event-driven architecture or real-time API technologies (WebSockets, Server-Sent Events)
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.
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
