Voice AI startup Giga raises $61M Series A

DoorDash and Giga Partnership

The Role We're looking for a Staff Software Engineer to own our iOS and Android SDKs what our customers use to embed Giga's chat and voice agents into their mobile apps. You'll lead the technical direction for how our agents show up on mobile, making architectural decisions around UI surfaces, animations, voice interactions, and performance that raise the bar for engineering quality across the team.

This is a role for someone who wants to build, not just advise. You'll write code, own the iOS and/or Android mobile infrastructure, and ship, but you'll also be expected to think beyond your immediate work. Working closely with design and our web frontend team, you'll identify what mobile experiences we should be building next and ensure our native integrations feel as considered and cohesive as our core product.

What You'll Work On You’ll drive the technical direction for how Giga agents live on mobile devices. Some examples of what you’ll own:

Mobile SDK architecture:

Leading the design, implementation, and evolution of our native iOS and Android SDKs. You’ll make the core architectural tradeoffs required to embed our voice and chat agents seamlessly into customer apps.

Deep OS integrations:

Pushing the boundaries of what native mobile can do. You will own how our agents interact with iOS / Android capabilities like voice routing, background execution, notifications, and app extensions so the agent feels truly "at home" on the device.

UI & performance excellence:

Sweating the details on motion, gesture handling, and accessibility. You’ll set the bar for mobile quality, ensuring our interfaces boast smooth animations, zero latency, and resilient offline behavior.

Tech Stack

Mobile: Swift (iOS), Kotlin (Android)

Backend: Python (Django/FastAPI), TypeScript (Node.js)

Frontend: TypeScript, Next.js (you’ll interact with this when needed)

Infrastructure: AWS, Modal, Kubernetes, Postgres

You Might Be a Fit If You

Have 8+ years of native iOS (Swift) engineering experience, with a track record of shipping complex apps or SDKs at scale

Have strong opinions on clean SDK and API design, and deeply empathize with the external developers who will integrate your work

Can take a vague product requirement and turn it into a fluid, responsive mobile experience without much guidance

Possess deep UX sensitivity—you sweat the details on motion, gesture ergonomics, and accessibility to make interfaces feel "just right"

Understand the depths of iOS and can push platform-native capabilities (like voice routing, background execution, and app extensions) to their limits

Want to be hands-on at a company where senior engineers ship code, not just review it

Are comfortable occasionally crossing the stack (e.g., GraphQL, Go) to unblock yourself and fine-tune end-to-end flows

Perks & Benefits

Competitive base + bonus + equity

Catered lunch daily

Dinner stipend

$500/month wellness & commuter benefit (gym, fitness classes, mental health)

401(k) plan

Medical, dental, and vision coverage
