Technical Lead – Frontend Infrastructure

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're looking for a Technical Lead – Frontend Infrastructure to join a challenging project — one of our most technically demanding builds, where this role owns the technical core. 
This is not a pure web role, though native mobile development isn't a hard requirement today. Regulated betting products may eventually require native-level work — biometric authentication, payment gateways, secure token storage, and compliant geolocation — that goes beyond what Capacitor (or a similar framework) covers out of the box. If and when that's needed, someone will need to build the native plugins these capabilities depend on; real Swift/Kotlin experience is a strong plus for this role, even if it's not the day-one focus.
You'll also architect the app to evolve over time: keeping business logic, state management, and networking cleanly decoupled from the UI layer so the platform can adapt its approach as performance and product needs grow.
This is an individual contributor role today; as the project scales, this will grow into a team you help build and lead.
More than a traditional developer, we're looking for someone with an analyst's mindset: strong at asking the right questions, evaluating trade-offs between architectural alternatives, and modeling complex systems — using AI-assisted development tools as part of the workflow, not as a replacement for that judgment.
Given the scope of this role — foundational architecture for a regulated, real-money platform at scale — reliability and resilience are first-class concerns, not an afterthought.

In this role, you'll

- Design and own the core infrastructure of our proprietary Next.js frontend: project structure, build pipeline, environment/config strategy, and deployment architecture.

- Define and implement a multi-brand / multi-tenant architecture (feature flagging, per-brand configuration) so a single codebase can serve all our markets.

- Own the mobile wrapper infrastructure. If native plugin work becomes necessary for capabilities standard web APIs can't cover — biometric authentication, payment gateways, secure token storage — either build those plugins directly (Swift/Kotlin) or coordinate with a native specialist to get them built.

- Own the multi-brand binary distribution pipeline using Fastlane, Xcode Schemes, and Gradle Flavors to publish distinct app listings from a shared codebase.

- Decide and implement the right Next.js rendering strategy for a mobile-embedded context — static exports and edge API consumption rather than dynamic SSR.

- Architect the app with business logic, state management, and networking strictly decoupled from the UI layer, for long-term flexibility as the platform evolves.

- Implement compliant, anti-spoofing geolocation appropriate for a regulated betting product.

- Ensure the app meets app store requirements for regulated/betting apps through robust native functionality.

- Define a safe update strategy (including OTA tooling) with version control appropriate for apps with real-time, live user sessions.

- Integrate observability tooling (e.g., Sentry, Datadog) that correlates native and JavaScript errors in a unified view.

- Build with reliability and resilience as core design constraints — graceful degradation, monitoring, and recovery paths appropriate for a regulated, real-money platform.

- Drive frontend performance work end-to-end (Core Web Vitals, Lighthouse scoring), including designing around structural constraints like third-party SDK/CDN dependencies.

- Partner with our DevOps team to define CI/CD requirements for build, test, and deployment across environments and brands (DevOps owns the pipelines; you define what the frontend needs from them).

- Define technical standards, tooling, and best practices for the frontend codebase that the rest of the team will build on.

- Integrate with backend and third-party systems at the infrastructure level as needed.

- Partner with the Developer Leader and Infra & Security to align frontend infrastructure with company-wide standards (AWS, security, cost optimization).

- Document architectural decisions and infrastructure setup so the approach is maintainable and transferable to the wider team.

What we look for in an exceptional candidate

- 8+ years of software engineering experience, including ownership of foundational architecture for a high-traffic, real-money or high-stakes platform — this role sets the technical foundation the whole project is built on.

- Strong, hands-on experience architecting and shipping production Next.js applications at scale.

- Proven experience designing multi-tenant or multi-brand frontend architectures (feature flags, per-tenant configuration, shared codebase strategies).

- Experience with Capacitor or a similar framework (e.g., React Native) for shipping web code as native mobile apps — we have a point of view here but are open to your input on the right approach.

- Experience implementing anti-spoofing / mock-location detection geolocation on mobile, ideally in a regulated (gaming, fintech, or similar) context.

- Experience with OTA update tooling (Capgo, Ionic Appflow, or similar) and safe versioning strategies for apps with live, real-time user sessions.

- Track record designing for reliability and resilience in high-stakes, regulated production systems — not just feature delivery.

- Comfortable working at the infrastructure layer: deployment architecture, environment strategy, build tooling — not just application code.

- Strong ownership mentality: this role sets the technical foundation others will build on.

- Comfort working with AI-assisted development tools as part of the day-to-day workflow.

Bonus points if you also have

- Real, hands-on experience writing or modifying native plugins in Swift (iOS) and Kotlin (Android) — a strong plus given the product may need native plugin work down the line, though it's not required on day one.

- Familiarity with the infra/release stack (AWS, CI/CD, app store releases).

- Prior experience in the gaming, betting, or fintech industry.

- Communication skills in written and spoken English or Portuguese.

- Experience leading/mentoring teams

How we do things

- We don't just "do" tasks; we take the lead and own the outcome.

- We aim to set the bar on every project we own.
