We are looking for a highly experienced Senior Android Engineer to join one of our clients — a technology company building cutting-edge conversational AI and voice solutions used by leading businesses across the retail, automotive, and restaurant industries.

This role requires deep, hands-on WebRTC expertise to support an urgent migration of an Android SDK from WebSockets to WebRTC. You’ll step in as a senior technical expert to help unblock complex challenges, stabilize real-time communication, and accelerate delivery of a production-grade SDK.

This is a short-term, high-impact engagement (up to 2 weeks / ~80 hours total), ideal for someone who enjoys solving hard problems quickly. There is also a potential opportunity to transition into a full-time role if the collaboration goes well.

Your responsibilities will include:

• Collaborate directly with senior Android engineers and the engineering owner to deliver a stable WebRTC-based Android SDK.
• Participate in daily syncs and focused working sessions to accelerate delivery and resolve blockers.
• Lead the migration of real-time communication from WebSockets to WebRTC within the Android SDK.
• Integrate, debug, and stabilize LiveKit-based real-time audio and streaming flows.
• Troubleshoot and resolve low-latency audio, networking, and streaming issues in production environments.
• Contribute hands-on to SDK-level Kotlin code, ensuring reliability, performance, and maintainability.
• Support QA efforts by identifying root causes of critical issues and validating fixes.

What we expect from you:

• Senior-level experience in Android development (Kotlin).
• Strong, hands-on WebRTC experience in production environments (required).
• Solid understanding of real-time audio, networking, and low-latency communication.
• Experience working with Android SDKs and shared libraries (not just app-level code).
• Ability to ramp up quickly and operate effectively with minimal hand-holding.
• Comfortable working in high-priority, time-constrained engagements.
• Professional English communication skills.

Bonus points for:

• Prior experience with LiveKit.
• Background in voice, audio streaming, or media-heavy Android applications.

Interview stages:

• Call with the recruiter.
• Technical interview from our side.
• Technical call with the client.

We offer:

• Remote-first work environment.
• Collaborative and motivated team.
• Impactful work improving patient treatment workflows.
• Professional growth with modern technologies.
• Autonomy and ownership of your work.
• Competitive compensation.
• Opportunity to contribute to future product phases.
