About the role

As a Senior Android Engineer, you will be responsible for designing, developing, and deploying mobile solutions that improve our micro-mobility functionality. That will mostly happen via coding in Kotlin, combining elements of backend-driven UI. Mobile engineers at Bolt usually get onboarded to back-end as well within their first year, so this could be a great opportunity if you are keen to grow as a full-stack engineer. All engineers at Bolt have a heavy inclination towards product thinking, so you will get a chance to shape up and drive exciting product initiatives yourself, in partnership with your Product Manager and the rest of the Micro-Mobility team! Our tech stack: Java, Kotlin, Coroutines, Flow, dagger 2, Retrofit , Glide, Room, Jetpack Compose.

Main tasks and responsibilities:

Designing, developing, A/B testing and deploying solutions that improve our user journey.

Working closely with back-end engineers to define and implement API integrations for micro-mobility-related business logic.

Testing your solutions thoroughly to make sure they meet their intended goals. That involves building meaningful unit tests and working closely with QA testers to cover usual and edge case scenarios.

Building a deep understanding of our products and of the way they impact the business metrics and end users. Contributing ideas and constructive feedback to our product roadmap.

Leading feature developments from idea to the point where they bring positive, validated impact to the end users.

Mentoring engineers and supporting new talent attraction.

About you:

You have experience testing and releasing mobile changes while ensuring their quality across multiple Android versions.

You have experience with unit testing and automation testing frameworks.

You are great at making data-driven decisions that positively impact the business.

You have a drive for leading initiatives and features till the end, even if the last mile is the hardest, and for monitoring and ensuring their success even after delivery.

You have strong principles towards writing clean, simple, secure, and maintainable code.

You possess a solid understanding of algorithms and data structures.

Experience is great, but what we really look for is drive, intelligence, and integrity. So even if you don’t tick every box, please consider applying!
