Job Description:

CRAVV Revolutionizing the kitchen experience Full Stack Flutter Engineer

Location: Onsite, Bengaluru | Experience: 1-2 years | Reports to: CTO

About Cravv

Cravv is building the future of the kitchen. We are creating a centralized ecosystem of smart devices and appliances that work in tandem to make cooking less stressful and more intuitive. Think of it as the nervous system for your kitchen, where every device talks to every other, and the whole thing just works. We are a small, fast-moving team that ships real products. No fluff, no theatre. If you are looking for a place where your work directly shapes the product and the company, this is it.

THE ROLE

We are looking for a Full Stack Flutter Engineer who can move across both mobile and backend systems, building Flutter experiences while also designing the APIs, real-time infrastructure, and streaming systems that power them. This is not a frontend-plus-some-API-calls role. A large part of the work involves real-time communication, synchronization, media pipelines, and distributed state across devices, mobile apps, and backend services. You will report directly to the CTO and have significant influence on technical direction. This is not a role where you will be handed a spec and asked to execute. You will be expected to reason through system design, own your work end-to-end, and think across client and server boundaries.

What You'll Work On

Flutter App Development
Build and own features across the Flutter codebase, covering UI, state, networking, and domain logic.
Work within a Clean Architecture setup (data / domain / presentation) with enforced dependency direction.
Manage app state using Riverpod 3.x with @riverpod code generation.
Build responsive, production-grade UI using Material 3 and custom design tokens.
Integrate real-time communication, including:
WebSockets
Streaming state updates
Session synchronization
Device communication
Work with media flows including:
HLS playback
WebRTC
Live audio and video streams
Write meaningful tests across widgets, providers, repositories, and contracts.
Backend Development
Build backend services using Go (Golang), Node.js, and Fastify.
Design and maintain REST APIs and real-time systems powering mobile and device experiences.
Work on WebSocket infrastructure, streaming systems, session and state synchronization, and media-related workflows.
Design backend systems around retries, idempotency, concurrency, and fault tolerance.
Work with PostgreSQL and Redis for persistence, caching, queues, and ephemeral state.
Build and maintain microservice-based systems with clear service boundaries.
Write maintainable, high-performance backend code with proper validation, error handling, and observability.

Required

WHAT WE'RE LOOKING FOR

Production Flutter Experience: You have shipped and maintained real Flutter applications on Dart 3.x. We care more about systems you have owned than years of experience.
Backend Systems Experience: You have built production backend systems using Go (Golang) and/or Node.js (preferably Fastify) involving APIs, real-time communication, high concurrency, and distributed systems.
Strong Architecture and State Management Skills: You are comfortable reasoning about application architecture, rebuild boundaries, async state, synchronization, caching, API contracts, and backend/frontend coordination.
Concurrency and Debugging Skills: A large part of the difficult work here involves timing and synchronization problems. You naturally think about failure modes before shipping, including:
Reconnect loops and retry storms
Stale state and race conditions
WebSocket synchronization and streaming edge cases
Session transitions
Experience: 1-2 years of professional software development experience.

Nice to Have

None of these are mandatory, but they are highly valuable:
go_router with redirect guards and nested navigation
Freezed, json_serializable, and build_runner
BLE integrations (flutter_blue_plus)
Redis pub/sub or streams
HLS or WebRTC systems
Media pipelines and FFmpeg workflows
Firebase (Crashlytics, Analytics, Auth)
Docker and containerized deployments
Microservice architecture experience
RBAC and auth systems
CI/CD and release engineering
Experience debugging systems across frontend, backend, and infrastructure layers

YOU PROBABLY WON'T ENJOY THIS ROLE IF

You prefer staying strictly frontend or strictly backend.
You rely on fully-specified tickets instead of reasoning through system design tradeoffs.
You struggle debugging async timing or distributed-state issues.
You optimize for quick patches over maintainable systems.
You avoid reading code outside your main stack.
