THE ROLES
We are hiring three Senior Full-Stack Engineers to join our cross-functional team pillars (which include Commercial Optimization, Product Innovation, and Tech Scale). Please note that specific pillar placement is not guaranteed and may vary from time to time based on business needs.
We are advertising broadly for full-stack developers, but are actively seeking candidates with distinct front-end or back-end specialisms to fulfill three specific profiles:
- Balanced Full-Stack Developer. Comfortable splitting impact 50/50 across C#/.NET and modern TypeScript / React
- Back-end focused Senior Developer. Deep C#/.NET and Azure SQL expertise with front-end awareness
- Front-end focused Senior Developer. Strong Modern React/TypeScript specialization to lead UI architecture and frontend modernization while collaborating with backend systems. Migrating legacy patterns through TypeScript into component-driven React
During the application review, we will evaluate your individual background against all three specialist tracks to find the best fit for your technical strengths.
KEY RESPONSIBILITIES
- Technical depth and delivery. Deliver high-quality features across the full stack (or front-end/back-end focus areas). Make independent technical decisions, consider architectural knock-on effects, and write clean, thoroughly tested code
- Migration and modernization. Help steer key initiatives—whether migrating C# services to .NET 8, optimizing Azure SQL performance, or converting legacy UI modules into scalable React components
- Technical debt and architecture. Identify and raise technical debt, author technical proposals on complex tickets, and champion quality standards
- PR reviews and mentorship. Provide constructive code reviews, pair with mid-level engineers, unblock colleagues proactively, and guide standard methodologies
- Collaboration and strategic AI. Work closely with PMs, Designers, and Marketing to shape what gets built, not just how. Strategically utilize and critically evaluate AI tools to accelerate delivery without compromising quality
Requirements
REQUIRED
- Minimum 5 years of progressive, professional software development experience
- Technical core:
- Strong proficiency in C# and the .NET ecosystem, OR
- Strong proficiency in React, TypeScript, HTML, and CSS (with web accessibility/WCAG experience for FE-focused candidates), OR
- Broad comfort working across the full stack and adapting to where team focus is required
- Data and cloud. Experience with relational databases (SQL Server / Azure SQL preferred)
- Engineering standards. Proven experience conducting thorough PR reviews, mentoring mid-level engineers, and working within Agile/SDLC frameworks
- Education. Bachelor’s or Master’s degree in Computer Science, Engineering, or equivalent practical experience
- Remote setup. Candidates must have an existing and suitable remote workstation setup
NICE-TO-HAVES
- Experience with React component library design systems or component-driven migration
- Hands-on experience with Azure Ecosystem (App Services, Azure SQL, Azure DevOps)
- Experience with Entity Framework Core or backend performance optimization
- Familiarity with OpenTelemetry, front-end performance monitoring, or testing frameworks (Jest, React Testing Library, Playwright)

Benefits
- 30 days' holiday per year (inclusive of UK bank holidays)
- 100% remote working
- Social events and annual meet ups

Prepare your application
Use the description above to assess your fit for Wordwall. This checklist is guidance from Resumize, rather than additional requirements from the employer. Imported listings can be shortened or change after collection, so confirm the complete description and current availability before sending an application.
Match requirements to evidence
Identify the responsibilities and skills the employer explicitly names. For each important requirement, choose one example from your work, education, training, or projects. Explain what you did, how you did it, and what changed as a result. Include a measurable outcome when you can support it. If you lack a requirement, describe related experience accurately instead of adding an unfamiliar skill to your resume.
Put the most relevant examples near the top of your resume. Keep job titles, dates, qualifications, and contact details consistent across your application materials. Use the employer’s terminology when it describes your experience accurately; a copied list of keywords does not explain your contribution. A short, specific bullet is easier to review than a paragraph that mixes several unrelated duties.
Check the working arrangement
Confirm the location, schedule, employment type, and any eligibility requirements on the employer’s site. A remote label does not establish worldwide eligibility or flexible hours. If compensation, benefits, equipment, travel, or contract duration are missing from this listing, write down your questions for the recruiter. Do not assume details from another opening at the same company apply to this role.
Review before submitting
Follow the employer’s requested file format and application instructions. Open your exported resume and check that its text is selectable, its sections read in order, and its links work. Proofread names, dates, and contact information. Share confidential work samples only when you have permission, and use an anonymized example when necessary.
Submit through a trusted employer or recruiting destination. If the original listing has disappeared, search the employer’s careers page for the title rather than assuming the vacancy remains open. Save the application date, job reference, and the version of your resume you sent. Those details help you prepare for a later conversation and avoid submitting conflicting information through several job boards.
Review your resume for writing and readability feedback, or browse other openings if this opportunity is unavailable.
