Responsibilities
- We are looking for engineers with deep expertise in either Android and Backend development - and an openness to contribute to the other area once onboarded.
- Design, build, and maintain highly scalable Android apps and/or backend services.
- Flexibility across domains:
- If your expertise is Android, be open to contributing to backend APIs and services.
- If your expertise is Backend, be open to contributing to Android app development.
- Ensure reliability, performance, and scalability in all systems.
- Collaborate with product managers, designers, QA, and DevOps to deliver features end-to-end.
- Participate in code reviews and design discussions, driving engineering best practices.
Requirements
- 7+ years of professional software engineering experience, with at least 3+ years in Android and Backend.
- Android (preferred): Proficiency in Kotlin (Java experience acceptable), Android SDK, UI/UX best practices, API integration.
- Backend (preferred): Hands-on experience with Golang (Java experience acceptable), micro-services, RESTful APIs.
- Strong knowledge of MySQL or TiDB.
- Solid understanding of cloud concepts (scalability, distributed systems, networking, storage). Direct GCP experience is not required.
- Strong foundation in system design, algorithms, and data structures.
- Familiarity with CI/CD pipelines and containerization (Docker/Kubernetes).
Nice-to-Have
- Experience with Kafka or other messaging systems.
- Exposure to frontend frameworks (React, Angular) is a plus.
What We Offer
- The chance to work on products at massive scale - millions of users, millions of parcels, billions of data points. Growth opportunities: expand into Backend if you are mobile-focused, or into Android if you are backend-focused. A collaborative environment with opportunities to mentor and be mentored. Competitive compensation, benefits, and career progression in a high-growth tech company.
- In short: We want engineers who are experts in Android (Kotlin) and Backend (Golang), and open to working across both domains to solve logistics problems at true scale.
Please apply only if you have relevant experience with the technologies and experience mentioned above.
