Building a Kotlin Developer resume?
Skip the blank page. Start with a template built for this role, then tailor it for each job you apply to.
Tip: use the template as a starting point, then swap in your own numbers and project names.
What to include in a senior-level Kotlin developer CV
Begin with a concise header and a 2-3 sentence summary that states your years of experience, core domains, and the value you bring. Include contact details, LinkedIn or portfolio links, and a UK location line so recruiters can filter for local or remote roles.\n\nAdd a technical skills section that lists Kotlin-related technologies such as coroutines, Flow, Ktor, Spring Boot, Jetpack libraries, and Kotlin Multiplatform where relevant.
Follow skills with a focused work experience section that emphasises impact, system ownership, and mentoring rather than a long list of routine tasks.\n\nFor UK roles, include a line confirming your right to work in the UK and any visa status. If applying to NHS or public sector positions, align salary expectations with UK pay bands and emphasise experience with data security and governance where relevant.
Work experience examples for senior-level Kotlin developer CV
Write each job entry with a short context sentence, followed by 3-5 achievement bullets that start with strong verbs and include measurable outcomes where possible. Focus on ownership items such as modules you designed, migrations you led, and performance improvements you delivered.
Where appropriate, reference the scale and context within UK organisations.\n\nExample bullet 1: Led the migration of a monolithic Java service to Kotlin microservices using Spring Boot and Ktor, reducing deployment time and improving test coverage across UK teams.
Mention the scale of the system and your design leadership.\n\nExample bullet 2: Architected and implemented coroutine-based data pipelines that improved throughput and reduced thread usage, while mentoring three engineers on async patterns. Mention reliability metrics and cross-team collaboration.\n\nExample bullet 3: Built a Kotlin Multiplatform module for shared business logic used by Android and iOS teams, enabling feature parity and reducing duplicated effort; coordinated across multiple UK product squads.

- 2Keep a concise portfolio or GitHub repository summary and link directly to relevant modules or examples of your architecture diagrams.
- 3Prepare 2 to 3 short stories mapped to your CV bullets so you can expand on design decisions and trade-offs during interviews.
