Who we’re looking for You design systems that empower autonomous agents to interact, make decisions, and execute tasks seamlessly – building both the application logic and the underlying cloud infrastructure needed to support scalable, dynamic agent operations. You have leveraged modern mobile tools and frameworks (Swift/SwiftUI, Kotlin, Jetpack Compose, and Kotlin Multiplatform) to architect and deliver iOS and Android applications from the ground up. At the same time, you know when to ask for help and don’t let pride or ego get in the way, because after all, you are part of a team.

This role will directly support our client Audi and have the opportunity to shape the development of their digital platform. “We are on the hunt for people who have an innovative mindset (you still dream of that moonshot project but are currently working on your side‑gig)! Lead, mentor, and manage a diverse team of AI engineers across iOS and Android. Communicate clearly with technical and non‑technical stakeholders.





AI Engineering Develop agents that can generate high‑quality native applications based on user and business needs. Develop agentic systems that reliably generate production‑grade code using Swift, SwiftUI, Kotlin, and related platform tools. Build and maintain automated evaluation pipelines (evals) for agent and skill outputs including LLM‑as‑judge scoring, regression test suites, and golden dataset validation so that prompt and model changes are measurable before they ship.

Own the prompt engineering lifecycle for assigned tools and skills version‑controlled prompt templates, parametric input injection, and structured system/user role separation ensuring prompts are testable, reproducible, and free of implicit context drift. Contribute to the team's MCP tooling catalog implement, test, and document MCP‑compatible integrations. 5+ years of mobile engineering experience, including lead ownership and responsibilities in an agile environment. ~ Experience with Kotlin and Android fundamentals. ~ Experience with AI coding agents such as GitHub Copilot. ~ Awareness of unit testing and automation frameworks such as XCTest, XCUITest, Mokkery, Espresso, or Robolectric. ~ Experience with offline storage, threading, and performance tuning. ~ Strong understanding of Git‑based version control and GitHub workflows. ~ Solid knowledge of cloud messaging and push notifications. ~ Ability to translate business requirements into explicit technical plans. ~ Experience designing and building agentic workflows – systems that plan, decompose tasks, execute, self‑validate, and iterate on failures.

Familiarity with LLM evaluation approaches: building golden test sets,



LLM‑as‑judge pipelines, and prompt regression testing; ability to quantify output quality with measurable metrics rather than vibes.

Experience building or consuming agentic workflows multi‑step tool chains, state machine‑based agents, or orchestration frameworks (LangGraph, LangChain, AutoGen, or custom) with an emphasis on deterministic routing and graceful failure handling. Demonstrated experience defining and rolling out engineering standards at a team or org level (coding conventions, PR workflows, testing mandates, API contracts). Track record of driving AI tool adoption within an engineering team – not just using the tools but creating the onboarding, guidance, and culture around them.

Experience with Kotlin Multiplatform. Spend your birthday any way you’d like, as long as it’s not at the office. Extra day off to enjoy every summer holiday and a week‑long end‑of‑year break.
