1What this role really is

This isn't just about writing code anymore; you'll be the person the team looks to for tough technical decisions and setting the right direction. You're the one who steps in when the architecture feels wobbly or when a new feature needs a solid technical plan from the ground up. Honestly, you're a player-coach: still hands-on with the trickiest bits of code, but also guiding others and making sure we're building things the right way, not just the fast way.

2What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Swift & KotlinExpert

Writing, reviewing, and debugging complex native iOS and Android features, including advanced concurrency and memory management patterns.

Xcode & Android StudioExpert

Mastering advanced debugging, profiling, and build automation features. Configuring complex project settings and troubleshooting build issues.

React Native or FlutterAdvanced

Architecting new cross-platform features, optimising performance, and managing complex state if we're using a hybrid approach. You'll be the go-to person for tough cross-platform challenges.

Git & GitHub/GitLabExpert

Enforcing branching strategies, resolving complex merge conflicts, mentoring juniors on advanced Git workflows (e.g., rebasing, cherry-picking), and managing repository security.

Fastlane or Gradle ScriptsExpert

Automating mobile build, testing, and deployment processes. Writing and maintaining custom scripts to streamline the release pipeline and manage 'code signing' complexities.

Jira & ConfluenceExpert

Managing sprints, creating detailed technical tasks with clear acceptance criteria, tracking team velocity, and documenting architectural decisions and technical specifications.

3What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing inWhere you are nowThe step above
Technical Architecture for New FeaturesProposes options with guidance, implements small components.Designs components within existing architecture, gets sign-off from senior.Designs major features, consults lead on complex integrations, owns implementation.
Code Review & StandardsReceives detailed feedback, applies standards.Provides feedback on minor issues, ensures adherence to standards.Enforces coding standards, provides in-depth technical feedback, mentors.
Technical Debt PrioritisationIdentifies minor issues, flags to senior.Proposes solutions for identified debt, implements with approval.Identifies significant debt, proposes refactoring projects, estimates effort.
Tooling & Library SelectionUses existing tools, learns new ones as directed.Evaluates alternatives for specific tasks, recommends to senior.Researches and recommends new libraries/tools, assesses pros/cons.

4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

App Crash-Free Rate
The percentage of user sessions that complete without an unexpected crash.
Target · Maintain 99.95% or higher across all mobile apps.

If we have 1,000,000 sessions in a month, we'd aim for fewer than 500 crashes. Your architectural decisions and code review rigour directly impact this.

Technical Debt Reduction
The number of identified technical debt items (e.g., legacy code, performance bottlenecks, architectural flaws) that are addressed and resolved.
Target · Reduce identified critical technical debt by 15% per quarter.

Identifying and refactoring a 'Massive View Controller' that was causing frequent bugs, reducing its complexity score by 30% and enabling two new features to be built on top of it without issue.

Team Velocity & Throughput
The average number of story points completed by your immediate team per sprint, reflecting efficiency and predictability.
Target · Increase team's average sprint velocity by 10% year-over-year, while maintaining quality.

If your team typically completes 30 story points a sprint, we'd expect to see that rise to 33 points over a year, not by cutting corners, but by improving processes, reducing blockers, and making better technical choices.

Code Review Turnaround Time
The average time it takes for your pull requests to be reviewed and merged, and for you to review others' pull requests.
Target · Average PR merge time under 24 hours for your own code; review 95% of assigned PRs within 8 business hours.

You submit a PR on Monday morning, and it's merged by Tuesday morning. Equally, you're not letting junior developers wait days for your feedback, unblocking them quickly.

Architectural Design & Guidance
Your ability to design robust, scalable, and maintainable solutions for complex features and to guide your team in implementing them correctly.
  • You're consistently consulted on major technical decisions. Your design proposals are clear, well-reasoned, and lead to successful implementations. Junior developers seek your advice on tricky problems, and your solutions prevent future issues.
Mentorship & Technical Leadership
How effectively you uplift the technical capabilities of your team members through coaching, code reviews, and knowledge sharing.
  • Your direct reports show measurable improvement in their coding practices and problem-solving skills. They feel supported and challenged. You actively lead technical discussions and present solutions at team or department-wide meetings. A junior developer you've mentored gets promoted or takes on more complex work.
Cross-Functional Collaboration
Your effectiveness in working with Product, Design, and Backend teams to deliver features, anticipating and resolving technical challenges proactively.
  • You're actively involved in early-stage product discussions, flagging technical constraints or opportunities. You build strong relationships with other leads. There are fewer 'surprise' issues arising from miscommunication between mobile and other teams. You're seen as a trusted technical voice by non-technical stakeholders.
Technical Documentation & Knowledge Sharing
The quality and completeness of technical documentation you create and your contribution to the team's shared knowledge base.
  • Key architectural decisions are clearly documented. New team members can onboard faster thanks to your guides. You actively contribute to our internal wiki or run tech talks that help the whole team learn.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Technical Puzzles

You'll spend a good chunk of your week tackling the hardest bugs, figuring out how to integrate new, tricky SDKs, or designing the architecture for a feature no one's built before. It's about getting your hands dirty with the really challenging stuff.

Debugging a 'race condition' that only appears on a specific Android device model, or designing a robust offline-first data synchronisation mechanism.

Mentoring and Growing a Team

You'll get a real kick out of seeing your team members improve. This means regular code reviews where you teach, one-on-one sessions helping them unblock, and leading technical discussions that raise everyone's game. Your success is tied to their growth.

Guiding a mid-level developer through their first major architectural contribution, or helping a junior developer understand advanced Swift concurrency patterns.

Shaping Technical Direction

You won't just be handed tasks; you'll be defining them. This role lets you influence the tech stack, set coding standards, and make key decisions about how we build and deliver mobile apps. It's about leaving your mark on the product's technical foundation.

Proposing and leading the adoption of a new state management library, or architecting a modular app structure that allows for faster feature development.

What frustrates people
  • Dealing with 'provisioning profile hell' or obscure Gradle build errors that eat up hours.
  • Receiving design mockups that are technically challenging or impossible to implement efficiently on both platforms, requiring careful negotiation with designers.
  • Having to fix bugs in poorly documented, legacy code written years ago by someone who's long gone.
  • Backend API changes that break existing mobile functionality without proper communication or versioning.
  • The constant need to stay updated with rapidly evolving mobile OS features and tooling, which can feel like a treadmill.
What this role does not give you
  • A purely individual contributor role with no team leadership or mentorship responsibilities.
  • A role where you only work on greenfield projects; there's plenty of legacy code to maintain and improve.
  • Complete autonomy over technical decisions without needing to justify them to product or management.
  • A predictable, '9-to-5' routine; critical bugs or urgent releases can sometimes demand extra effort.

6Who you work with

This role is critical for the technical health and future direction of our mobile platform. Your architectural choices and technical guidance directly influence the quality, performance, and maintainability of our apps. Get it right, and we scale gracefully; get it wrong, and we're constantly patching holes, slowing down innovation across the entire product suite. You'll be shaping the technical capabilities of your team and setting standards for how we build mobile experiences.

Inside the business
  • Product Managers (for feature requirements and roadmap alignment)
  • UI/UX Designers (for design system adherence and user experience)
  • Backend Engineering Leads (for API contracts and system integration)
  • QA Leads (for testing strategy and release quality)
  • Other Mobile Tech Leads (for cross-team consistency and shared components)
Outside the business
  • App Store Review Teams (Apple & Google, for compliance and approval)
  • Third-party SDK/API Providers (for integration and support)

7What you need before you start

Not a wish list. The things you would be expected to already have.

  • Proven track record of 8+ years building and shipping complex mobile applications on both iOS and Android platforms (native or cross-platform).
  • Demonstrable experience leading technical projects or workstreams, including architectural design and mentoring junior developers.
  • Expert-level proficiency in either Swift/iOS or Kotlin/Android development, with strong familiarity in the other, or advanced expertise in a cross-platform framework like React Native or Flutter.
  • Deep understanding of mobile application architecture patterns (e.g., MVVM, MVI, Clean Architecture) and their practical application.
  • Extensive experience with Git, CI/CD pipelines, and automated testing frameworks specific to mobile development.
  • Strong problem-solving skills, with a history of debugging and optimising complex mobile performance issues.
  • Excellent communication skills, capable of articulating complex technical concepts to diverse audiences.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, mobile development has its repetitive bits and head-scratching moments. Imagine if you could cut down on those and focus on the really interesting, high-impact architectural work. Good news: AI tools are here to help you do exactly that. We're not talking about replacing you; we're talking about making you a mobile development powerhouse.

Our AI Productivity Hub is designed to integrate seamlessly into your daily workflow, giving you access to tools that automate the mundane, explain the complex, and even help you write better tests. As a Lead, you'll not only use these tools yourself but also help your team adopt them, multiplying your collective efficiency.

Smart Code Generation & Refactoring

Use tools like GitHub Copilot or similar AI-powered IDE extensions to instantly generate boilerplate code for data models, networking layers, or even complex UI components. Need to refactor a 'Massive View Controller'? AI can suggest patterns and even draft the new structure, saving you hours of tedious typing and helping you focus on the architectural improvements.

Advanced Debugging & Error Explanation

When you hit a cryptic 'linker error' or a strange crash log, paste it into an LLM like ChatGPT-4 or Claude. These tools can often provide instant, clear explanations of what the error means, common causes, and a list of potential solutions, cutting down debugging time significantly. No more endless Stack Overflow searches for obscure build issues.

Automated Unit & UI Test Generation

As a Lead, ensuring test coverage is crucial. AI tools can analyse your code and automatically generate comprehensive unit tests for your functions or even scaffold UI tests for new screens. This means your team can achieve higher test coverage faster, reducing regressions and freeing up time for more complex testing scenarios.

Intelligent Documentation & PR Summaries

Spend less time writing tedious documentation. AI can scan your code changes and automatically draft clear, concise summaries for your pull request descriptions, generate user-facing release notes, or even create initial drafts of technical design documents, letting you focus on the strategic content.

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Lead Mobile Developer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

  • Searching and planning stay free. You only pay when you start learning.
  • Your credits are yours. Regulated, and they don't vanish when a subscription ends.
  • Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

This route runs to 2 national skill standards. That is a real journey.

Zavmo shapes a learning experience as unique as you are. It fits how you learn, your pace and the work you already do. Every step stays benchmarked to recognised national standards. That’s the plan for becoming a Lead Mobile Developer: personal to you, and it still counts. The first steps are free.
