[Hiring] Frontend Software Engineer @BetWarrior

Role Description

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.

In this role, you'll:

• Design & Specify (SDD): 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.
• Build Complex Solutions: Model complex state flows and design resilient interface architectures capable of operating in high-traffic, low-latency environments.
• Collaborate Directly: Work closely with Product and UX teams in small, autonomous squads, acting as the technical bridge between business ideas and viable architectures.
• Ensure Functional Quality (GDD/BDD): Translate business scenarios into clear acceptance criteria and well-structured system behaviors, actively collaborating with the Automation QA team.
• Maintainability & Future Thinking: Design components and abstractions with long-term maintainability in mind, anticipating edge cases, critical bugs, and bottlenecks.

Qualifications

• 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.

Requirements

• 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).

Benefits

• Fast-moving, collaborative, and demanding team with high standards for quality.
• Opportunity to grow with the company and take ownership of your work.
• Visible contributions and defined growth paths based on delivery.
