Why we have this role

While traditional Lead roles focus on manual coding, this position is centered on defining the high-level specs, conventions, and reviews that enable AI agents and your team to produce elite iOS code together.
You maintain full ownership of the code and architecture, but your primary impact comes from engineering the specific conditions and guardrails under which AI can deliver reliably.
The core of your mission is to treat the development process as a product, diagnosing where agents fail and closing those gaps through superior prompts, tooling, and system design.

What to expect

You will define and continuously evolve our iOS standards, establishing coding conventions, architectural patterns, and quality gates that AI agents can consistently follow—and that fail loudly when they don't.
You will operate the iOS branch of our "agent factory" by monitoring agent runs, diagnosing failure modes, and feeding corrections directly back into prompts, conventions, tooling, and the specification layer.
In close collaboration with our product team, you will author the iOS specification and ticket templates required to produce agent-ready work.
You will review pull requests generated by agents against our architectural and quality standards, stepping in to intervene whenever an agent stalls.
You will take full ownership of the iOS app's quality, stability, and release outcomes—managing Crashlytics, performance, and release processes—regardless of whether the code was written by a human or an agent.
You will actively shape the iOS codebase to be AI-friendly by enforcing modular boundaries, ensuring deterministic tests, maintaining machine-readable documentation, and designing clear interfaces.
As a leader and mentor to the iOS team, you will share your knowledge, conduct code reviews, and help the team maximize their potential when working alongside AI agents and tools.
You will drive the technical decisions for our fully native Swift development, working completely free of legacy code and enjoying full autonomy over your tools and approach.

You bring over five years of experience as a Senior or Lead iOS Developer, including a track record of guiding teams to ship real, scalable products to production.
You have demonstrable, hands-on production experience using AI-assisted development tooling.
You hold strong, well-founded opinions on what makes a codebase amenable to AI-assisted development, backed by the architectural taste required to execute those ideas.
You have a proven history of making critical technical decisions, designing robust architectures, and successfully guiding teams through their implementation.
You possess excellent technical writing skills in English, which is crucial since our specifications and conventions are a core part of the product and will be authored by you.
You demonstrate independence, initiative, and a strong bias toward shipping over polishing.
You are open to working from our Hamburg office 1–2 days a week.

You will be working, learning, and collaborating alongside dedicated colleagues in a modern, highly AI-focused environment.
You will benefit from short feedback loops, fast decision-making processes, and the opportunity to exert a real influence on the future of the iOS stack at endios.
We offer you the opportunity to develop freely within a growing company in a dynamic industry, allowing you to shape the future while continuously growing on a professional level.
You will have the chance to take on responsibility from day one, leveraging our lean and agile decision-making pathways to make an immediate impact.
We provide flexible working hours based on a culture of trust, along with 30 days of annual vacation.
You will have the option to work remotely for several days a week.
We offer an attractive, competitive salary accompanied by a variety of additional benefits, such as the HVV ProfiCard and a company pension subsidy.
