Software Engineer, Native Delivery

Hightouch is an Agentic Marketing Platform powered by a composable customer data platform that helps marketing teams build and ship end-to-end campaigns. The Senior Software Engineer will build SDKs, on-device experiences, and backend systems for delivering personalized experiences in native apps and on the web, while owning projects end to end and collaborating directly with customers.

Responsibilities:

• You will own and deliver projects start to finish, work directly with customers integrating our SDKs into their apps, and have real influence over what we build
• Building a great SDK requires reasoning about the full round-trip between the device and our backend: how events are collected, how eligibility is evaluated, how messages are delivered, and how the host application renders them. You'll co-design the API and backend alongside the rest of the team
• Cross-channel orchestration on-device. Deciding what a user sees, on which device, at which moment, without channels stepping on each other or one user getting hit five times in a session
• In-app messaging and custom UX. Custom messaging and on-device experiences triggered while a user is active in a customer's app. The SDK evaluates eligibility locally against rules pushed down from our backend
• Behavioral data collection. Custom events, screen views, and user attributes batched on-device and shipped to our backend to feed real-time targeting
• SDK developer experience. Clear init, sane defaults, useful errors, and docs that respect the host engineer's time. Versioning and distribution that doesn't break customer app builds

Requirements:

• You're motivated by high ownership and comfortable in a fast-paced, startup environment
• Native development across iOS, Android, or React Native, with enthusiasm for working across all of them and learning what you don't already know
• Shipping an SDK or library that other developers integrated into their own applications
• Designing systems that span a server, a network, and a client, where the same problem looks different on each side and the contract between them matters as much as the code
