Tip: use the template as a starting point, then swap in your own numbers and project names.
What UK employers look for in a mid-level backend developer CV
UK employers want to see that you can own features from design through deployment, and that you can mentor junior colleagues while shipping reliable code. They look for specific technologies, measurable impact, and examples of problem solving that match the job description.
You should aim to show scope, scale, and results. Describe the systems you worked on, the size of the codebase or user base when relevant, and any measurable improvements you delivered.
CV header and summary for a mid-level backend developer CV
Your header should include your full name, job title, location in the UK or remote preference, telephone number, email, and a link to GitHub or a portfolio. Keep contact details concise and ensure links open to polished code or projects.
Write a two to three sentence summary that states your job title, years of backend experience, core languages and frameworks, and the type of role you want. For example, you are a mid-level backend developer with three to five years of experience in Python and PostgreSQL, seeking API and system design work at a product-focused company.
If applicable, mention your right to work in the UK and any visa sponsorship needs.
Skills section with focus and keywords
Group skills into categories such as Languages, Frameworks, Databases, and Tools to make scanning easier. Include only technologies you can discuss confidently in an interview and mirror keywords from the job posting.
Put the most important skills first; for example listing the primary backend language, then the framework, then the database. This helps applicant tracking systems and UK recruiters spot the match quickly.
Experience section: Structure and examples for mid-level backend developer CV
List roles in reverse chronological order and include company name, location (UK city), dates (DD/MM/YYYY format), and your title. Under each role, write three to six achievement bullets that start with an action verb, include a technical context, and show measurable outcomes where possible.
Focus each bullet on the impact you delivered, not day-to-day tasks. For example, say that you reduced API latency by a percentage, increased throughput, reduced error rate, improved deployment times, or mentored colleagues and led design reviews.
Examples
Developed RESTful API endpoints in Python using FastAPI and PostgreSQL, reducing average latency by 28% and increasing throughput by 2x.
Led a small team to redesign a critical service, introducing containerised deployments (Docker) and Kubernetes-based orchestration, cutting deployment time by 60%.
Implemented comprehensive monitoring and alerting, reducing MTTR by 40% and improving issue triage.
Mentored three junior developers, reviewed design decisions, and ran weekly knowledge-sharing sessions to raise code quality.
Collaborated with frontend teams to define API contracts and security controls, improving resilience against common attack vectors.
Additional Tips
- 1Keep the top of your CV focused on the roles and skills that matter most for your target job.
- 2Use your GitHub link to point directly to a small set of well-documented repositories or a single highlighted project.
- 3Practice telling the story behind two or three key bullets so you can explain trade-offs and decisions in interviews.
