About The Role

We are looking for a Full-Stack Engineer with 3–5 years of production experience who can take ownership of features end-to-end across mobile, backend, web/admin tooling, testing, and infrastructure.

This role requires strong backend and SQL fundamentals, production Flutter experience, and the ability to work independently on systems where correctness, reliability, and server-side validation are critical.

What You’ll Own

You will own complete vertical slices of features, including:

• Mobile screens and user-facing functionality
• Backend APIs and feature modules
• Wallet and reward use cases
• Server-side validation and business rules
• Admin and internal tooling
• Database migrations
• Automated tests
• Background workers and queues
• Monitoring and alerts
• Store releases
  
  

Mobile Development

Work with:

• Flutter 3.11
• Riverpod
• go_router
• Dio
• AppLovin MAX
• Firebase
  
  

You will be responsible for building production-quality mobile features, integrating ad SDKs, and supporting App Store / Play Store releases.

Backend Development

Work with:

• NestJS 11
• TypeScript
• TypeORM
• PostgreSQL 18
• Redis
• BullMQ
• Jest
  
  

You will build and maintain feature modules, APIs, wallet/reward functionality, fraud rules, workers, database migrations, and automated tests.

Web & Admin

Work with:

• Next.js 16
• React 19
• Tailwind 4
• Vercel
  
  

You will contribute to the marketing site and internal admin console, including functionality such as:

• User lookup
• Withdrawal review
• Partner configuration
• Internal operational tooling
  
  

Infrastructure

This is not a dedicated DevOps role, but you will be expected to ship and maintain your own infrastructure-related changes.

You should be comfortable reading and extending:

• Terraform
• AWS
• RDS
• ElastiCache
• CloudWatch
  
  

This includes adding or maintaining monitoring and alerts when required.

What We’re Looking For

Must Have

• 3–5 years of experience shipping production software that you have owned
• Strong experience with server-side TypeScript and a typed ORM
• Strong SQL skills and the ability to write queries independently and read a query execution plan
• Production experience with Flutter, or strong native mobile development experience with the ability to ramp up quickly in Dart
• Working knowledge of React for building internal tools and interfaces
• Experience writing automated tests alongside the feature being developed
• Strong written English and ability to communicate technical decisions clearly
• Ability to work independently and take ownership of features from implementation through delivery
  
  

Nice to Have

Experience with any of the following will be a strong advantage:

• Payments, ledgers, payouts, and reconciliation
• Ad mediation SDKs or attribution
• Fraud and abuse prevention, including fingerprinting and velocity limits
• Redis and production queue systems
• Terraform and AWS
• App Store / Play Store review and release processes
  
  

How We Work

We value engineering discipline, ownership, and verifiable outcomes.

Our development approach includes:

• Plan before coding and define a verifiable outcome
• Use Clean Architecture with clearly defined boundaries
• Write tests alongside features
• Use real PostgreSQL and Redis in testing where appropriate
• Review money-related paths twice
• Maintain one owning document for each important contract
• Keep commits small and focused
• Provide clear and honest summaries of completed work
