Backed by Balderton Capital.
About the role
Spam Blocker identifies unknown callers, blocks spam and scams, and screens suspicious calls before they ring. It’s a consumer product operating at the intersection of mobile platforms, real-time calling, and Hiya’s global reputation and security systems. The team is small and owns Spam Blocker end to end, from the native apps and backend services to subscriptions, entitlements, and releases. We don’t split work by platform. Engineers move between Swift, Kotlin, and the backend depending on what the product needs.
What they're looking for
- Demonstrated Kotlin Multiplatform experience in production applications. Specifically shipping shared KMP code, or deciding where a shared boundary belongs
- Production code shipped outside your primary platform in the last two years, on iOS, backend, or web, that you can show us. Shipping on both iOS and Android is a strong plus
- Experience carrying a significant architecture or platform change through a mobile team, from proposal to adoption, including bringing other engineers along
- Comfort in the services behind the app: APIs, entitlements, analytics. You do not wait for a backend engineer to unblock a mobile feature
- A high quality bar with automation as the default. You build automation around repeatable failure modes and use device testing deliberately, for the things only a device can tell you
- Active use of AI coding agents. You separate planning from execution on non-trivial work and can say what has worked, what has not, and where you draw the line on trusting an agent's output
More about this role
At Hiya, we’re making business calls more trusted, useful, and effective.
Voice remains one of the most important ways businesses communicate with their customers, but the value of a call depends on trust. When customers do not recognize who is calling or why, important conversations are missed, customer relationships suffer, and business outcomes are harder to achieve.
Hiya helps businesses create trusted calling experiences that benefit both sides of the conversation: enterprises can reach customers with confidence, and customers can answer with confidence. Our products support branded business calling, trusted caller identity, call performance insights, customer engagement, and voice security capabilities that help businesses strengthen relationships and improve outcomes.
This role sits in a core business area for Hiya and is focused on helping SMB and enterprise customers succeed.
