The Role
As the
Senior Android Developer
, you'll take
full ownership of the Android migration process
, bringing all existing

future expansion to tablets and wearable devices
.
Beyond migration, you'll design and build new Android apps and SDKs that enable
AI experimentation and client integration
, ensuring users have a seamless and robust experience.
This is not your typical app dev role, you'll be working at the intersection of Android engineering, SDK development, and applied AI, helping to shape products that are literally the first of their kind.
If you're a
Kotlin specialist
who thrives on ownership, architecture, and building clean, scalable mobile systems, this is your lasting opportunity to leave a visible impact on a truly emerging technology.
Key Responsibilities
- Lead the migration
of all iOS functionalities into Android — taking complete ownership of the process. - Develop Android applications and SDKs
that enable client integration with cutting-edge AI technology. - Collaborate cross-platform
with iOS engineers to ensure consistency and parity. - Architect Android solutions

iOS/Swift experience
or willingness to pick it up for future cross-platform needs.
Soft Skills & Cultural Fit:
- Self-driven and able to work autonomously.
- A practical problem-solver who enjoys tackling complex challenges.
- Collaborative and humble — confident in your abilities but not ego-driven.
- Strong communication skills, able to work seamlessly with quieter team members.
Preferred Experience:
- Prior experience in
B2B environments
(with longer, more deliberate release cycles) over B2C. - Track record of
taking ownership
of Android roadmaps and delivering high-quality results.
Top Priorities in the First 6 Months
- Migrate all existing iOS functionalities
to Android. - Own and lead
the Android development process. - Deliver quickly
to meet client needs and enable product growth.
Career Growth & Future Opportunities
This role offers two exciting long-term paths:
- Own the Android function
within the company, becoming the go-to technical authority. - Progress into a
Senior Principal Software Engineer
role covering both Android and iOS platforms.
You'll also gain exposure to applied
AI, biometrics, and behavioural computing
— areas growing rapidly across global tech markets.
Why Join
- Be part of an
early, high-impact engineering team
driving a new category of AI. - Collaborate with a world-class team in
AI research, design, and product development
. - Shape Android architecture from the ground up with
