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.
