## Why you’ll want to work with us

For a small team, Afero engineers collectively do a little bit of everything—from cloud applications and infrastructure to mobile development on multiple platforms, firmware on a wide range of devices, to board-level hardware design and implementation of secure wireless devices. If you enjoy deep dives into assorted technology stacks to understand end-to-end system workflows, can adapt past experiences to new solutions, and can communicate technical ideas effectively, Afero is a fantastic opportunity to explore and to expand your expertise.

## What we’re looking for

We're building the mobile experience for Afero's Hubspace smart home product line. As a Senior Software Engineer on the mobile team, you'll work across the full mobile stack. From Flutter UI down to native platform code and help shape the architecture of a production app used by millions of customers.

You'll work on real problems: connected device onboarding over BLE, real-time device control, GraphQL API integration, and an ongoing migration from Redux to a Provider-based architecture. This is not a greenfield role, you'll inherit a mature codebase and be expected to improve it.

We want people with passion to build best in class technology, who will drive the evolution and scale of Afero’s platform. The range of disciplines and experience represented at Afero is broad and deep, and everyone on the team contributes meaningfully to our culture and our growth.  We’re looking for builders and problem solvers who will bring perspective and skills to support our success, people with enthusiasm for digging into complexity, creating solutions, and driving effectiveness in a collaborative environment.

## Key Responsibilities

- Build and maintain the Flutter application across iOS and Android, including native platform channel integrations in Swift and Kotlin
- Design and implement shared business logic using Kotlin Multiplatform, reducing duplication between platforms
- Integrate and evolve GraphQL APIs, working closely with backend teams on schema design and query optimization
- Participate in architectural decisions, including the ongoing migration from Redux to ChangeNotifier/Provider
- Own features end-to-end: from API contract through UI, including test coverage
- Mentor mid-level engineers and contribute to code review culture

Required Qualifications

- 8+ years of mobile software engineering experience
- Strong Flutter/Dart — you've shipped a production Flutter app and understand its rendering model, state management trade-offs, and platform channel boundaries
- Native iOS (Swift), native Android (Kotlin) and you can write platform-specific code when Flutter alone isn't enough
- Kotlin Multiplatform; experience building or consuming shared KMP modules
- GraphQL; client-side experience with queries, mutations, subscriptions, and caching strategies
- Comfort working in an IoT or connected hardware context is a strong plus (BLE, device state synchronization, real-time data)
- Collaborative and direct; this team moves fast and expects engineers to push back when something is wrong
- This role is a hybrid position; candidates must be able to come into the Los Altos, CA office at least three days per week
- Applicants must be authorized to work for any employer in the U.S.

## Nice to have

- Experience with Firebase (Crashlytics, Analytics, Messaging, Remote Config)
- Familiarity with Redux or similar unidirectional data flow patterns
- Background in smart home, embedded, or hardware-adjacent products

Afero is an equal opportunity employer. All applicants will be considered for employment regardless of race, color, national origin, religion, sex, age, disability, sexual orientation, gender identity, veteran or disability status.
